Short answer

What makes a good case study presentation?

A good case study presentation has an engaging story, a clear structure, real data, visual aids, client testimonials, and a strong call to action. It informs and inspires, making the audience believe they can achieve similar results.

Dull case studies can cost you clients.

A boring case study presentation doesn't just risk putting your audience to sleep—it can actuallyl ead to lost sales and missed opportunities.

When your case study fails to inspire, it's your bottom line that suffers.

Interactive elements are the secret sauce for successful case study presentations.

They not only increase reader engagement by 22% but also lead to a whopping 41% more decks being read fully , proving that the winning deck is not a monologue but a conversation that involves the reader.

Let me show you shape your case studies into compelling narratives that hook your audience and drive revenue.

Let’s go!

How to create a case study presentation that drives results?

Crafting a case study presentation that truly drives results is about more than just data—it's about storytelling, engagement, and leading your audience down the sales funnel.

Here's how you can do it:

Tell a story: Each case study should follow a narrative arc. Start with the problem, introduce your solution, and showcase the results. Make it compelling and relatable.

Leverage data: Hard numbers build credibility. Use them to highlight your successes and reinforce your points.

Use visuals: Images, infographics, and videos can enhance engagement, making complex information more digestible and memorable.

Add interactive elements: Make your presentation a two-way journey. Tools like tabs and live data calculators can increase time spent on your deck by 22% and the number of full reads by 41% .

Finish with a strong call-to-action: Every good story needs a conclusion. Encourage your audience to take the next step in their buyer journey with a clear, persuasive call-to-action.

How to write an engaging case study presentation?

Creating an engaging case study presentation involves strategic storytelling, understanding your audience, and sparking action.

In this guide, I'll cover the essentials to help you write a compelling narrative that drives results.

What is the best format for a business case study presentation?

4 best format types for a business case study presentation:

• Problem-solution case study
• Before-and-after case study
• Success story case study
• Interview style case study

Each style has unique strengths, so pick one that aligns best with your story and audience. For a deeper dive into these formats, check out our detailed blog post on case study format types .

What to include in a case study presentation?

An effective case study presentation contains 7 key elements:

• Introduction
• Company overview
• The problem/challenge
• Your solution
• Customer quotes/testimonials

To learn more about what should go in each of these sections, check out our post on what is a case study .

How to motivate readers to take action?

Based on BJ Fogg's behavior model , successful motivation involves 3 components:

This is all about highlighting the benefits. Paint a vivid picture of the transformative results achieved using your solution.

Use compelling data and emotive testimonials to amplify the desire for similar outcomes, therefore boosting your audience's motivation.

This refers to making the desired action easy to perform. Show how straightforward it is to implement your solution.

Use clear language, break down complex ideas, and reinforce the message that success is not just possible, but also readily achievable with your offering.

This is your powerful call-to-action (CTA), the spark that nudges your audience to take the next step. Ensure your CTA is clear, direct, and tied into the compelling narrative you've built.

It should leave your audience with no doubt about what to do next and why they should do it.

How to adapt your presentation for your specific audience?

Every audience is different, and a successful case study presentation speaks directly to its audience's needs, concerns, and desires.

Understanding your audience is crucial. This involves researching their pain points, their industry jargon, their ambitions, and their fears.

Then, tailor your presentation accordingly. Highlight how your solution addresses their specific problems. Use language and examples they're familiar with. Show them how your product or service can help them reach their goals.

A case study presentation that's tailor-made for its audience is not just a presentation—it's a conversation that resonates, engages, and convinces.

How to design a great case study presentation?

A powerful case study presentation is not only about the story you weave—it's about the visual journey you create.

Let's navigate through the design strategies that can transform your case study presentation into a gripping narrative.

Add interactive elements

Static design has long been the traditional route for case study presentations—linear, unchanging, a one-size-fits-all solution.

However, this has been a losing approach for a while now. Static content is killing engagement, but interactive design will bring it back to life.

It invites your audience into an evolving, immersive experience, transforming them from passive onlookers into active participants.

Which of these presentations would you prefer to read?

Use narrated content design (scrollytelling)

Scrollytelling combines the best of scrolling and storytelling. This innovative approach offers an interactive narrated journey controlled with a simple scroll.

It lets you break down complex content into manageable chunks and empowers your audience to control their reading pace.

To make this content experience available to everyone, our founder, Itai Amoza, collaborated with visualization scientist Prof. Steven Franconeri to incorporate scrollytelling into Storydoc.

This collaboration led to specialized storytelling slides that simplify content and enhance engagement (which you can find and use in Storydoc).

Here’s an example of Storydoc scrollytelling:

Bring your case study to life with multimedia

Multimedia brings a dynamic dimension to your presentation. Video testimonials lend authenticity and human connection. Podcast interviews add depth and diversity, while live graphs offer a visually captivating way to represent data.

Each media type contributes to a richer, more immersive narrative that keeps your audience engaged from beginning to end. You can upload your own interactive elements or check stock image sites like Shutterstock, Adobe Stock, iStock, and many more. For example, Icons8, one of the largest hubs for icons, illustrations, and photos, offers both static and animated options for almost all its graphics, whether you need profile icons to represent different user personas or data report illustrations to show your findings.

Prioritize mobile-friendly design

In an increasingly mobile world, design must adapt. Avoid traditional, non-responsive formats like PPT, PDF, and Word.

Opt for a mobile-optimized design that guarantees your presentation is always at its best, regardless of the device.

As a significant chunk of case studies are opened on mobile, this ensures wider accessibility and improved user experience , demonstrating respect for your audience's viewing preferences.

Here’s what a traditional static presentation looks like as opposed to a responsive deck:

Streamline the design process

Creating a case study presentation usually involves wrestling with an AI website builder .

It's a dance that often needs several partners - designers to make it look good, developers to make it work smoothly, and plenty of time to bring it all together.

Building, changing, and personalizing your case study can feel like you're climbing a mountain when all you need is to cross a hill.

By switching to Storydoc’s interactive case study creator , you won’t need a tech guru or a design whizz, just your own creativity.

You’ll be able to create a customized, interactive presentation for tailored use in sales prospecting or wherever you need it without the headache of mobilizing your entire team.

Storydoc will automatically adjust any change to your presentation layout, so you can’t break the design even if you tried.

How to Present a Case Study like a Pro (With Examples)

Written by: Danesh Ramuthi Sep 07, 2023

Okay, let’s get real: case studies can be kinda snooze-worthy. But guess what? They don’t have to be!

In this article, I will cover every element that transforms a mere report into a compelling case study, from selecting the right metrics to using persuasive narrative techniques.

And if you’re feeling a little lost, don’t worry! There are cool tools like Venngage’s Case Study Creator to help you whip up something awesome, even if you’re short on time. Plus, the pre-designed case study templates are like instant polish because let’s be honest, everyone loves a shortcut.

What is a case study presentation?

What is the purpose of presenting a case study, how to structure a case study presentation, how long should a case study presentation be, 5 case study presentation examples with templates, 6 tips for delivering an effective case study presentation, 5 common mistakes to avoid in a case study presentation, how to present a case study faqs.

A case study presentation involves a comprehensive examination of a specific subject, which could range from an individual, group, location, event, organization or phenomenon.

They’re like puzzles you get to solve with the audience, all while making you think outside the box.

Unlike a basic report or whitepaper, the purpose of a case study presentation is to stimulate critical thinking among the viewers. 

The primary objective of a case study is to provide an extensive and profound comprehension of the chosen topic. You don’t just throw numbers at your audience. You use examples and real-life cases to make you think and see things from different angles.

The primary purpose of presenting a case study is to offer a comprehensive, evidence-based argument that informs, persuades and engages your audience.

Here’s the juicy part: presenting that case study can be your secret weapon. Whether you’re pitching a groundbreaking idea to a room full of suits or trying to impress your professor with your A-game, a well-crafted case study can be the magic dust that sprinkles brilliance over your words.

Think of it like digging into a puzzle you can’t quite crack . A case study lets you explore every piece, turn it over and see how it fits together. This close-up look helps you understand the whole picture, not just a blurry snapshot.

It’s also your chance to showcase how you analyze things, step by step, until you reach a conclusion. It’s all about being open and honest about how you got there.

Besides, presenting a case study gives you an opportunity to connect data and real-world scenarios in a compelling narrative. It helps to make your argument more relatable and accessible, increasing its impact on your audience.

One of the contexts where case studies can be very helpful is during the job interview. In some job interviews, you as candidates may be asked to present a case study as part of the selection process.

Having a case study presentation prepared allows the candidate to demonstrate their ability to understand complex issues, formulate strategies and communicate their ideas effectively.

The way you present a case study can make all the difference in how it’s received. A well-structured presentation not only holds the attention of your audience but also ensures that your key points are communicated clearly and effectively.

In this section, let’s go through the key steps that’ll help you structure your case study presentation for maximum impact.

Let’s get into it. 

Open with an introductory overview 

Start by introducing the subject of your case study and its relevance. Explain why this case study is important and who would benefit from the insights gained. This is your opportunity to grab your audience’s attention.

Explain the problem in question

Dive into the problem or challenge that the case study focuses on. Provide enough background information for the audience to understand the issue. If possible, quantify the problem using data or metrics to show the magnitude or severity.

Detail the solutions to solve the problem

After outlining the problem, describe the steps taken to find a solution. This could include the methodology, any experiments or tests performed and the options that were considered. Make sure to elaborate on why the final solution was chosen over the others.

Key stakeholders Involved

Talk about the individuals, groups or organizations that were directly impacted by or involved in the problem and its solution. 

Stakeholders may experience a range of outcomes—some may benefit, while others could face setbacks.

For example, in a business transformation case study, employees could face job relocations or changes in work culture, while shareholders might be looking at potential gains or losses.

Discuss the key results & outcomes

Discuss the results of implementing the solution. Use data and metrics to back up your statements. Did the solution meet its objectives? What impact did it have on the stakeholders? Be honest about any setbacks or areas for improvement as well.

Include visuals to support your analysis

Visual aids can be incredibly effective in helping your audience grasp complex issues. Utilize charts, graphs, images or video clips to supplement your points. Make sure to explain each visual and how it contributes to your overall argument.

Pie charts illustrate the proportion of different components within a whole, useful for visualizing market share, budget allocation or user demographics.

This is particularly useful especially if you’re displaying survey results in your case study presentation.

Stacked charts on the other hand are perfect for visualizing composition and trends. This is great for analyzing things like customer demographics, product breakdowns or budget allocation in your case study.

Consider this example of a stacked bar chart template. It provides a straightforward summary of the top-selling cake flavors across various locations, offering a quick and comprehensive view of the data.

Not the chart you’re looking for? Browse Venngage’s gallery of chart templates to find the perfect one that’ll captivate your audience and level up your data storytelling.

Recommendations and next steps

Wrap up by providing recommendations based on the case study findings. Outline the next steps that stakeholders should take to either expand on the success of the project or address any remaining challenges.

Acknowledgments and references

Thank the people who contributed to the case study and helped in the problem-solving process. Cite any external resources, reports or data sets that contributed to your analysis.

Feedback & Q&A session

Open the floor for questions and feedback from your audience. This allows for further discussion and can provide additional insights that may not have been considered previously.

Closing remarks

Conclude the presentation by summarizing the key points and emphasizing the takeaways. Thank your audience for their time and participation and express your willingness to engage in further discussions or collaborations on the subject.

Well, the length of a case study presentation can vary depending on the complexity of the topic and the needs of your audience. However, a typical business or academic presentation often lasts between 15 to 30 minutes. 

This time frame usually allows for a thorough explanation of the case while maintaining audience engagement. However, always consider leaving a few minutes at the end for a Q&A session to address any questions or clarify points made during the presentation.

When it comes to presenting a compelling case study, having a well-structured template can be a game-changer. 

It helps you organize your thoughts, data and findings in a coherent and visually pleasing manner. 

Not all case studies are created equal and different scenarios require distinct approaches for maximum impact. 

To save you time and effort, I have curated a list of 5 versatile case study presentation templates, each designed for specific needs and audiences. 

Here are some best case study presentation examples that showcase effective strategies for engaging your audience and conveying complex information clearly.

1 . Lab report case study template

So, you’ve spent hours crafting the perfect case study and are now tasked with presenting it. Crafting the case study is only half the battle; delivering it effectively is equally important.

Forget boring reports and snooze-inducing presentations! Let’s make your case study sing. Here are some key pointers to turn information into an engaging and persuasive performance:

• Know your audience : Tailor your presentation to the knowledge level and interests of your audience. Remember to use language and examples that resonate with them.
• Rehearse : Rehearsing your case study presentation is the key to a smooth delivery and for ensuring that you stay within the allotted time. Practice helps you fine-tune your pacing, hone your speaking skills with good word pronunciations and become comfortable with the material, leading to a more confident, conversational and effective presentation.
• Start strong : Open with a compelling introduction that grabs your audience’s attention. You might want to use an interesting statistic, a provocative question or a brief story that sets the stage for your case study.
• Be clear and concise : Avoid jargon and overly complex sentences. Get to the point quickly and stay focused on your objectives.
• Use visual aids : Incorporate slides with graphics, charts or videos to supplement your verbal presentation. Make sure they are easy to read and understand.
• Tell a story : Use storytelling techniques to make the case study more engaging. A well-told narrative can help you make complex data more relatable and easier to digest.

Nailed your case study, but want to make your presentation even stronger? Avoid these common mistakes to ensure your audience gets the most out of it:

Overloading with information

A case study is not an encyclopedia. Overloading your presentation with excessive data, text or jargon can make it cumbersome and difficult for the audience to digest the key points. Stick to what’s essential and impactful. Need help making your data clear and impactful? Our data presentation templates can help! Find clear and engaging visuals to showcase your findings.

Lack of structure

Jumping haphazardly between points or topics can confuse your audience. A well-structured presentation, with a logical flow from introduction to conclusion, is crucial for effective communication.

Ignoring the audience

Different audiences have different needs and levels of understanding. Failing to adapt your presentation to your audience can result in a disconnect and a less impactful presentation.

Poor visual elements

While content is king, poor design or lack of visual elements can make your case study dull or hard to follow. Make sure you use high-quality images, graphs and other visual aids to support your narrative.

Not focusing on results

A case study aims to showcase a problem and its solution, but what most people care about are the results. Failing to highlight or adequately explain the outcomes can make your presentation fall flat.

How to start a case study presentation?

Starting a case study presentation effectively involves a few key steps:

• Grab attention : Open with a hook—an intriguing statistic, a provocative question or a compelling visual—to engage your audience from the get-go.
• Set the stage : Briefly introduce the subject, context and relevance of the case study to give your audience an idea of what to expect.
• Outline objectives : Clearly state what the case study aims to achieve. Are you solving a problem, proving a point or showcasing a success?
• Agenda : Give a quick outline of the key sections or topics you’ll cover to help the audience follow along.
• Set expectations : Let your audience know what you want them to take away from the presentation, whether it’s knowledge, inspiration or a call to action.

How to present a case study on PowerPoint and on Google Slides?

Presenting a case study on PowerPoint and Google Slides involves a structured approach for clarity and impact using presentation slides :

• Title slide : Start with a title slide that includes the name of the case study, your name and any relevant institutional affiliations.
• Introduction : Follow with a slide that outlines the problem or situation your case study addresses. Include a hook to engage the audience.
• Objectives : Clearly state the goals of the case study in a dedicated slide.
• Findings : Use charts, graphs and bullet points to present your findings succinctly.
• Analysis : Discuss what the findings mean, drawing on supporting data or secondary research as necessary.
• Conclusion : Summarize key takeaways and results.
• Q&A : End with a slide inviting questions from the audience.

What’s the role of analysis in a case study presentation?

The role of analysis in a case study presentation is to interpret the data and findings, providing context and meaning to them. 

It helps your audience understand the implications of the case study, connects the dots between the problem and the solution and may offer recommendations for future action.

Is it important to include real data and results in the presentation?

Yes, including real data and results in a case study presentation is crucial to show experience,  credibility and impact. Authentic data lends weight to your findings and conclusions, enabling the audience to trust your analysis and take your recommendations more seriously

How do I conclude a case study presentation effectively?

To conclude a case study presentation effectively, summarize the key findings, insights and recommendations in a clear and concise manner. 

End with a strong call-to-action or a thought-provoking question to leave a lasting impression on your audience.

What’s the best way to showcase data in a case study presentation ?

The best way to showcase data in a case study presentation is through visual aids like charts, graphs and infographics which make complex information easily digestible, engaging and creative. 

Don’t just report results, visualize them! This template for example lets you transform your social media case study into a captivating infographic that sparks conversation.

Choose the type of visual that best represents the data you’re showing; for example, use bar charts for comparisons or pie charts for parts of a whole. 

Ensure that the visuals are high-quality and clearly labeled, so the audience can quickly grasp the key points. 

Keep the design consistent and simple, avoiding clutter or overly complex visuals that could distract from the message.

Choose a template that perfectly suits your case study where you can utilize different visual aids for maximum impact.

Practice with experts

Using case interview examples is a key part of your interview preparation, but it isn’t enough.

At some point you’ll want to practise with friends or family who can give some useful feedback. However, if you really want the best possible preparation for your case interview, you'll also want to work with ex-consultants who have experience running interviews at McKinsey, Bain, BCG, etc.

If you know anyone who fits that description, fantastic! But for most of us, it's tough to find the right connections to make this happen. And it might also be difficult to practice multiple hours with that person unless you know them really well.

Here's the good news. We've already made the connections for you. We’ve created a coaching service where you can do mock case interviews 1-on-1 with ex-interviewers from MBB firms . Start scheduling sessions today!

Case Presentation Interview is a unique variant of the traditional case study interview . The underlying structure of the case is the same - you’re placed in a hypothetical business situation and are asked to resolve a business problem . However, in this type of case study, you’re asked to solve the case by working independently rather than by collaborating with the interviewer. Case Presentation Interviews are less commonly used but are as important for  candidate assessment as traditional ones. You can encounter them as part of the BCG or Bain first or second-round interview, as well as when applying for managerial roles in the corporate strategy departments or startups. They have been growing in popularity in recent years given their 360° approach to testing candidates in “on-the-job” work leveraging real-life scenarios .

The specific details of this type of case interview differ by the company. In the case of BCG or Bain, you’re usually given a handout of 20 to 40 pages of information including graphs, charts , or tables , and given 1 to 2 hours to analyze information and prepare 3 to 5 slides with your analysis and recommendation. However, there are three major differences among different types of written case studies you should be aware of:

Depending on the case study , you might get an overall business problem or a specific list of 3-4 key questions to investigate and answer. In the former, you have to decide on areas to explore and you have the freedom to solve them, while in the latter you should focus on areas mentioned in the questions. The difference is similar to interviewer- vs interviewee-led traditional cases.

If you’re in the recruitment process for BCG or Bain you’ll most probably get 1-2 hours to analyze information and prepare the slides . However, for smaller consultancies and business roles it became a standard to give case studies with a 2-3 days deadline - which requires your resolution to be more refined and thorough.

In the majority of written case interviews , you are expected to create slides from scratch . This involves both the visual and content sides of the presentation. However, you might also encounter case interviews where you’ll be given (partially) pre-filled slide templates (e.g., titles, graphs, charts ). Then your focus should be on analysis and filling in the missing numbers or messages.

Case Presentation Interview simulates the consulting job environment by placing you in a hypothetical business situation with access to data and further presentation of your insights and work. It helps to predict how you would perform if you joined the company for the role . While they are aimed at testing similar skills to traditional case interviews , they help to assess your critical reading and problem-solving skills , as well as your ability to research and analyze information . It also tests your communication and more “technical” skills in preparing an actual presentation.

The following points are the usual assessment criteria for Case Presentation Interview:

• Logical and structured thinking (using logic and reason to derive conclusions & then being able to convey complex messages in a simple way)
• Data and information analysis (using an analytical approach to data & prioritizing key outcomes)
• Slide making (making the output easy to understand and digest through a compelling story and clear visuals/content)
• Presentation skills (communicating in a clear, concise and persuasive way)

There is a clear five-step process you should follow to successfully solve the Case Presentation Interview:

You should start solving the Case Presentation Interview by making sure you understand the objective and the primary business question you try to answer. Solving the wrong problem or misunderstanding key challenges is the quickest way to fail the case interview. Spend time reading the instructions and understanding the primary problem or questions you are trying to answer. This will allow you to understand the most important areas of the case and derive your framework. In case you get a specific list of questions then focus on those.

Before you begin collecting, reading, and analyzing the data, you should create a basic framework to help guide your analysis. This framework will also shape your target presentation agenda and storyline . Remember - each case is unique and it doesn’t necessarily fit in one of the typical frameworks described in multiple casebooks (applicable especially in the interviewee-led approach). Don’t be afraid to apply a tailored solution, an out-of-the-box way of thinking could make you shine among all other applicants (but still - be complex). You should start by selecting 3 to 4 areas that are needed to answer the primary objective of the case study. If you received a list of detailed questions these can often substitute the framework and there’s no need to add anything else. However, you may identify other important areas and you might decide to add them to your framework. Also, if you received pre-filled slide templates, they will usually provide support on what are the areas you should focus on. Otherwise, you will need to create your framework from scratch . Use your knowledge of the business problems , screen through the data available, and determine the main areas of your framework .  

The next step is to understand the data available to solve the case. For interviews with only 1-2 hours of preparation time, you will be given a handout with information to be leveraged for analyzing and solving the case. Don’t spend time reading and analyzing every slide. That would take too much time. Instead, understand what data and information are out there. Decide and prioritize which information is important to read and analyze in more detail later to solve the case interview. Case presentation interviews have strict time constraints , so you want to make the most of the limited time that you have.

Next, match different pieces of information that exist to areas in your framework . This will enable you to conduct further analyses and solve the case study.  

You should already know what questions you need to answer based on the framework you created. You also understand the data and information available for answering each question. All that is left is to process and analyze information and data that is relevant for each area of the framework. As you analyze the data and start answering major questions in your framework make sure to summarise your learnings and takeaways . It is important you keep a record of key answers that you can then leverage for the storyline of your presentation as well as make it easier to remember the work and decide on target recommendations. Following an analysis of all relevant materials, you should have a list of key takeaways and answers for all core elements of your framework . You should now proceed to define the comprehensive recommendation derived from these data points which would be collectively supported by them.

Not each takeaway will support your final recommendation. Sometimes you might find a takeaway that goes against your hypothesis and proposed recommendation. In this case, you need to mediate conflicting insights and decide on which one is the most important. You might decide that contradicting takeaway is a potential risk or the next step to be further discovered in the way of investigation.

Remember that there is no such thing as a wrong recommendation. As long as your proposal is supported by data-driven evidence your solution will be solid enough for the interviewers.  

As soon as you decide on a recommendation and collect all the supporting data and evidence , it’s time to prepare a structure for the presentation slides. For this purpose, you can structure your presentation into a simple communication pyramid structure - start with the recommendation and 3 supportive arguments , deep dive into supportive reasons and data on the following slides (one slide for each argument), finish with a summary of all covered information, and then present potential next steps or open questions . In case of having received pre-filled slide templates, the structure of your presentation slides might have been already decided for you. Otherwise, you can leverage the approach described above. In the end, you should derive a structure of 6-10 slides which you can start filling in with the content.

Once you finalize the structure of the presentation, the next step is to start putting your content and key messages on them. Make sure you use descriptive slide titles communicating the message of the slide , as well as creating a sound storyline when combined together. Moreover, prepare your slides in a way they’re easy to digest. None of the slides should have more than one, powerful key message.

In case you’re left with some time, review your slides one more time. You should correct any mistakes or errors as well as clean up the slides for them to look neat and polished. Obvious omission can be perceived as a big question mark to your ability to work under pressure in a client-facing role.

Moreover, you should spend the last minutes thinking about potential questions  interviewers might ask you during your presentation. These might include your approach used to analyze or your conclusions. Be prepared for challenges of your assumptions and interpretations of the data!

There are 4 small tips I’d like to share with you that you should keep in mind when preparing Case Presentation Interview:

• Start your presentation with your recommendation first and then follow the framework
• Focus on slide titles and make sure they make a coherent storyline
• Always remember that one slide should have only one message
• Include next steps and open questions at the end of your presentation

You can practice those by solving an example of a BCG Written Case study which can be found here .

9 Tips For Delivering A Stellar Case Presentation Interview

A Case study interview is a staple in the recruitment process for firms in the professional services industry, particularly management consulting firms. But recently, many companies use what is called a “case presentation interview” to test more than just the candidate’s ability to crack a case. 

Recently, case presentation interviews are used for analyst-level employees in many healthcare, tech, and e-commerce consulting firms. 

In this article, you will learn what skills a case presentation interviewer is looking for, the biggest challenge of a case presentation interview, the major tips you can use to ace your case presentation interview and land your dream job! + a bonus Insightful video with tons of examples for consulting case interviews.

What is a case presentation interview?

Also called a case study presentation interview is an advanced phase of the interview process where the interviewee is asked to solve a business problem, given little time and information about the problem. Generally, the case is presented to the hiring manager and his peers.

Case Presentation Interviews usually follow this process:

What skills are the interviewer looking for during a case presentation interview?

The ultimate goal of the interview is not necessarily to see if the person being interviewed can solve the business problem (although, very important), but to see if they can think on their feet, reason like a consultant, communicate their insights effectively before clients and/or the CEOs. 

A case presentation interview is an interviewee’s opportunity to prove to their interviewer that their soft skills and analytical skills are relevant within a realistic business context.

What is the biggest difficulty in case presentation interviews?

Time management tops the list of difficulties that would be faced during a case presentation interview. The firm often provides the interview candidate with a large set of data and extrinsic information. 

9 Tips on how to deliver an excellent Case Presentation Interview

You have to prepare extensively for your case presentation interview, and one of the ways you can do this is by brushing up on your mental maths skills. 

You can do this by randomly giving yourself a short but budgeted time to solve semi-difficult maths problems without using a calculator.

You can use information from case books as practice just so that can get ahead of the curve. It would also be wise for you to extract just the prompt and data as many case books already come with answer keys. 

There are three things you can do to help yourself:

While case presentation interviews are not held like traditional interviews where the interviewer and candidate discuss extensively, it is still important to know as much about the firm as you can find. 

You can use these four easy steps to create structure:

Ensure that you think properly about the framework that you need to include in the key categories. You also need to think properly about the data that would be needed to test the hypothesis. 

Unknown to many case presentation interview candidates, a case presentation interview question packet already has all the data that they need right before their faces- this is one of the biggest advantages of case presentation interviews.  

Most traditional case interviews pose as difficult because the relevant data has to be mined; this is not the case for case presentation interviews, the limited information supplied to the interviewee contains everything they need. Once you form your hypothesis, you can cut right to the chase and start testing instantly to see what direction you should head towards. 

While you might have put in all the hard work in preparation and creating their presentation, it would be an absolute waste of effort if you deliver the presentation shakily. 

Just so you know, whether the allotted time is 30 minutes or 2 hours, it would go by very quickly, hence the need for a time budget. Interviewers often understand the limited time constraints, but you must move on from spending your time analyzing the information and draw out their presentation quickly.

Transparency is an impressive quality to many firms, and they would be impressed by your honesty. 

Case Interview for Beginners Video

Regardless of how difficult it may seem to be, relax, and have fun with it. As long as you did your best to fully prepare, leaving no stone unturned, you will be fine.

With this, chances are very high that both you and the firm reach a mutual realization and an agreement if the firm and the role are great for you. 

We hope that this article has helped simplify the preparation process – one way or the other. Check back soon for more tips and guides on a similar subject matter.

What Is A Case Interview?

Research a career in management consulting, and the case interview is THE issue. But if this is your first exposure to a case interview, you are probably wondering: what is it really like?

In a case interview, applicants have to solve real-world problems live with an interviewer . The cases mimic the kinds of scenarios consultants work with daily – most are pulled directly from real-life client experiences.

The case typically consists of a problem or situation faced by an organization (company, NGO, or government agency). Applicants are given the problem verbally, and in a set amount of time must analyze the case, determine what data is needed, ask for the data, compute potential scenarios, and deliver a presentation on that solution.

While there is also a behavioral portion to the consultant hiring process, the case interview is the most significant filter. It’s make or break , and at firms like McKinsey, it’s mostly break – under 10% of interviewees get an offer .

We’ve compiled this Complete Prep Guide to make sure you make it – no breaking here! Our in-depth preview of what to expect from the interview will help you know how to demonstrate you’re ready to be hired as a consultant.

Case Interview Process

Now you know what the case interview is, but that still doesn’t tell you There are small variations between firms, but generally the case interview portion of the hiring process is quite consistent across the industry.

A typical new hire goes through 4-6 interviews in total, which are usually divided into two rounds occurring on separate days. (Superdays, with Round 1 in the morning and Round 2 in the afternoon of the same day, are possible but less common in consulting than in banking.) The interviews are each 30-60 minutes long.

The first 5-15 minutes of each consulting interview are usually spent on a “ Fit Interview .” In the fit interview, the firm’s screener/s—usually consultants themselves—ask you a variety of questions to better understand your sense of motivation, leadership, teamwork, and your general fit for the company.

After the fit interview, you’ll go straight into the case interview, which usually lasts 20-40 minutes . We’ll go into the 8 parts of a case interview in just a bit, but here is a kickstart:

• Capture the problem (take notes and ensure you understand it)
• Plan your attack and share your plan
• Ask for data and compute answers based on what you get
• Provide a recommendation

Sound easy? Read on.

There are important differences between the first and the second round of case interviews . The first round tests you on a variety of general skills, including time management. In most interviews, you have only 20 minutes – and the firms usually reject 75% of applicants in this round because they can’t digest and solve a problem in a short time.

In the second round, the material requires deeper analysis and applicants work with more senior interviewers. Further, interviewers in the second round sometimes play the role of “bad cop” or “devil’s advocate” along the way, asking you to rethink your methods and offering potentially misleading information to make your task more difficult and test conviction. If you want a more in depth understanding of this, check out our article: “ Structure of Three Case Interview Rounds “.

While the case interview is consistently challenging, firms do add nuance and individuality to the overall consulting interview process. Here are some exceptions:

• Most fit interviews are part of the overall interviews, but some fit interviews can be totally separate from case interviews and facilitated by different interviewers.
• Most case interviews are completed 1:1 with an interviewer, but some case interviews situate applicants in teams instead of working independently.
• Most case interviews are live and presented verbally, but for some you get a packet either overnight or for 1-3 hours prior to the interview and result in a presentation.

The good news? Prepping for a traditional out-loud case interview will ensure you are ready for all exceptions to the rules.

Upcoming Case Interview and Consulting Events

Case Interview Frameworks

Case interview frameworks give you a helpful starting point to solving the case interview. These frameworks offer a systematic way to approach different kinds of business problems .

Case frameworks, however, are wildly misunderstood. Your goal is not to memorize a million frameworks and then apply the “right” framework to a particular problem.

The goal is to memorize a handful of core frameworks to give yourself a mental repository of categories that you can pick and choose from to create your own custom framework for the problem you’re facing.

Some frameworks we’ll take a look at in this next section:

• The “market entry framework” to help you decide if a client should enter a new market
• The Victor Cheng case interview framework – Cheng took the well-known 3 C’s framework (which stands for Company, Customers, and Competition) and added Products as a fourth category of consideration.

For an even deeper dive into frameworks, read our Ultimate Guide to Frameworks .

Market Entry Framework

Consultants often help clients decide whether to enter new markets. Therefore, you will see a scenario in your case interview where a market entry question is being proposed.

The market entry framework is the general framework for dealing with this kind of scenario. Relevant factors often include the situation of the market being entered, the state of the competition, and the process & strategy of first entering the market.

Profitability Framework

Maximizing profits is the essential purpose of any company or enterprise, and is an important consideration for non-profit and government organizations as well. 100% of consulting projects are bottom-line related, and thus many case interview questions involve considering ways to improve profitability.

The profitability framework is a basic approach for analyzing profit problems. There are always a variety of drivers to examine, but the first step is to separate cost and revenue. A deeper look into the profitability framework will familiarize you with the nuances of applying the framework.

Here’s an example of a generic profitability framework in action:

You can also watch a profitability case interview here .

M&A Case Framework (Mergers & Acquisitions)

How do you advise a company when they are considering merging with, acquiring, or being acquired by another company? Many aspiring consultants overlook the possibility of being assigned a mergers & acquisitions case and then are surprised to be confronted with one during their interview. Avoid that mistake by getting comfortable executing an M&A case framework.

In this framework, the question is simple: should one company invest in or buy another?

The primary directive in the M&A case framework is to drill down on your understanding of the acquiring company’s position. The acquiring company is motivated by either short-term or long-term considerations – a financial buyer buys to increase short-term value and sell, while a strategic buyer acquires to hold the target for the long-term.

Your response in an M&A situation will be binary: either a merger/acquisition is advisable or it isn’t.

Other Frameworks:

Pricing framework.

Deciding how to price products & services may seem like a relatively banal activity in comparison with mergers & acquisitions. But in reality, pricing decisions are some of the most influential decisions any company makes, exerting a great influence on profitability. It’s no surprise that consulting applicants often rely on the pricing framework model in their interviews.

3 Cs Framework

The 3 Cs framework gives a bird’s-eye view of a company’s overall situation. The 3 Cs themselves refer to the categories of Company, Customers, and Competition. Separating information and inquiries into these three categories helps give a comprehensive sense of a company’s operation in a given moment.

Porter’s 5 Forces Framework

Sometimes a particular case or client scenario requires you to develop an understanding of a whole industry or sector, as well as how a particular company fits into that overall environment. This is what the Porter’s 5 Forces Framework is designed to help with. The 5 Forces to consider are: the threat of new entrants, competitive dynamics, supplier power, buyer power, and the threat of substitutes.

Case Frameworks Are Not a “Silver Bullet”

Remember – frameworks exist to help you figure out an approach to difficult problems. They are not a pre-written script to force-fit in response to a particular question you’re being asked. The framework serves the problem, not the other way around.

Think of a case interview more like a chess game, in which each framework represents one potential maneuver in a longer sequence of moves.

Also, remember that the case interview is not just a problem to be solved but an audition. You want to demonstrate to your interviewers that you have the ability to respond to a question fluidly, independently responding to new inputs and maintaining perspective as you think on your feet. It is not helpful to demonstrate a rote memorization of the frameworks .

Mental Math for Case Interviews

Solid fluency in mental math is essential to good case interview performance – and to the work of consulting in general. No calculators are allowed in case interviews, so if you’re rusty (and you probably are), it’s time to dust off the cobwebs. One thing we highly recommend is going off your calculator six months in advance of your case interview.

Honing your mental math skills is an essential part of case interview prep. Start with our free drills here . 

If you really want to sharpen your abilities, we’ve designed an entire course on mental math for consulting . Doing things like calculating tips, analyzing your budget, etc., can help you get comfortable working with numbers in the way you’ll have to during the interview process.

4 Steps for Case Math

When you’re working on a complex case, you can easily lose yourself in calculations. Thankfully, here’s a sneak peak of our simple four-step approach you can use to keep your math organized and on point. Get a more in-depth breakdown of case math.

Recap the Problem

These problems are delivered verbally. Some people are great at math but bad at listening, so the first step is to review the data and what you’re solving for. An out-loud recap gives you time to think and ensures you start with accurate information. The recap also gives the interviewer the confidence you will formulate a clear and coherent approach. And if you’ve misunderstood something about the problem, recapping it gives the interviewer the chance to intervene.

Structure Your Approach

After the recap, organize a systematic approach – out loud. Devise a step-by step algebraic approach to get an answer. Remember, you’re not just structuring the approach for your own sake—you’re also demonstrating to the interviewer that there is a logical methodology behind your work.

Run the Numbers

You have the right information and a process to solve for the answer. Now, perform the mathematical operations you laid out. Use your mental math and double-check to ensure your answer makes sense.

Develop and Deliver Insights

The first three steps produce an answer. This fourth and final step – sharing about what the answer means and what the organization should do next – separates top performers from amateurs, and is 100% required in second round interviews.

Case Interview Examples

We have prepared over 25,000 applicants for case interviews. So far, no one has come back and said “that was so much easier than I expected.”

That’s the bad news.

But here’s some good news – the case interviews you’ll encounter at different firms have a lot in common, and they will demand largely similar things from you as an applicant. For that reason, the first 80% of your case interview prep should be general (i.e., not firm-specific).

Our curriculum will prepare you for any case interview, from MBB firms to boutique firms. Still, there are some things that make every firm unique. In order to help you get a sense of what you’ll encounter at some of the consulting firms to which you’ll be applying, here are several case interview examples.

McKinsey Case Study Interview Examples

You can find many McKinsey case study interview examples on the McKinsey website , and in our Case Library, which contains over 500 cases (with solutions and guidance so you can learn as you go). Get instant access here . 

BCG Case Interview Examples

Just like McKinsey, BCG also includes multiple BCG case interview examples on its website. Again, there are dozens of BCG case interview examples (including solutions) in our Case Library .

Bain Case Interview Examples

As with its competitors, Bain includes Bain case interview examples on its website/a>. While practicing by yourself is fine if you’re a beginner, take the next step by working 1:1 with one of our MBB coaches. We’ll coach you through cases, assess your strengths and weaknesses, and build a plan for you to get interview-ready.

Boutique Firms Case Interview

The basic structure of a case interview is not very different at a boutique firm. Some boutiques specialize in certain industries or sectors, which will then be represented in the types of cases they give out.

Here’s an example called “ Promotional Planning ” from Kearney.

Compared to material from the MBB firms, boutique firms’ case interview examples are a little bit harder to come by, that is, if you look outside of our Case Library .

Case Interview Prep: Be Ready for Your Interview

The case interview is the hurdle in an entire management consulting career. The single biggest regret we hear? Under-preparing.

Here are key tips to avoid common interview prep pitfalls:

Case Interview Prep Timeline

In a perfect world, your case interview prep timeline should start 6 months before your interview – time for 1-2 out loud interviews a week and plenty of math and structure drills in between. Look ahead to the time you’ll start the interview process and build your prep schedule backward from there.

Of course, many people find themselves with less than six months before their desired interview time. Heck, I had 2 weeks. That doesn’t disqualify you – it just means you must be strategic to prepare on an accelerated timeline. 

In our Black Belt program, one of our MBB coaches will build a personalized prep plan for you that is 1 week or 1 year long, and based on any background.

If you are in school, there are certain optimal times to apply. 

U.S. Undergrads:

Peak recruiting season for juniors and seniors begins in July. Start preparing for the case interview (and get your resume ready!) by April.

International Undergrads:

Application drop in October. Begin case interview prep by June.

Advanced Degree Candidates (ADCs):

We recommend applying for the competitive Bridge Programs in March, and full-time recruiting begins in July. For the best shot, begin preparing for the case interview in November or December of the prior year. 

First year MBAs will interview in January for internship roles. However, diversity recruiting begins at conferences as early as September so you should begin interview prep in May, after matriculation but before even coming to campus.

Second years re-recruiting for full-time roles should begin to refine their casing skills as soon as February (after internship interviews). For second years who decide after a summer internship that consulting is the right career path for you, start prep as soon as you figure out you want to pursue consulting. Your best option?

Audio Review

The case interview is an in-person out-loud process, and your communication and people skills are just as important as your technical know-how. This is a verbal as well as a mental test – if you don’t simulate the interview environment in your prep process by practicing out-loud, you won’t succeed.

We differ from the norm here, but we help make sure you’re more successful so we’re okay with that.

Don’t read books. If you must read, do it after you’ve listened to or watched case interviews, and tried at least 10 out loud on your own with a partner.

Start to get a sense of what the case interview looks and sounds like by watching our walkthroughs on YouTube .

Once you’ve gotten a sense of what a case sounds like, work with an expert coach to put it all together for yourself. Our coaches conduct mock case interviews and offer actionable feedback – this is the most effective way to get ready for the case interview.

Practice Out Loud

Left to their own devices, many aspiring consultants study as they would for any other test – by silently doing cases on their own. This presents a huge problem when you arrive on the day of the interview and discover that you have to talk, write, and think at the same time.

Even if you think you’re considering how to communicate the work you’re doing as you do practice cases, you’ll find that you sound much smarter in your head than you will out loud.

The reason the case interview is a verbal process is so that the interviewer can follow your thought process in real time. Practice out loud to build your confidence and identify weak spots that otherwise won’t surface until it’s too late!

Structuring Process

Structure is everything. In fact, the most common feedback is “be more structured” and that starts the minute the case begins.

As you proceed through practice case studies, take 2 minutes to structure your approach and 2 minutes to read it out. Use a timer. End with your hypothesis.

Do Your Homework

The average successful applicant does 30 to 50 practice cases – and yes, some people pass with 10 cases, and others need 100. How do you know what you need?

First – if you want to optimize your case prep, review every case you do right after you finish it and keep a log of your learnings. Repeat mistakes without fixing them is a recipe for disaster.

Practice with a Case Partner

Partner with other aspiring consultants who share your ambition to help keep you accountable. Get firsthand feedback on your performance is helpful – but in addition, providing feedback to other people helps improve self-awareness.

Use the practice for what it is – an opportunity to get over fear and build confidence. Be careful, though. If you decide NOT to hire an expert coach, don’t put too much weight on the feedback you get from amateur case partners.

Get Expert Help

We’ve said it already but it bears repeating: working with an expert coach will increase your odds of acing the case interview. Our coaches first succeeded as candidates, and then served as interviewers. 

An expert coach can also cut the number of necessary practice cases in half. We recommend the Black Belt Interviewer package , which offers 8 hours of 1:1 coaching. A staggering 60% of our Black Belts earn offers from top 10 firms nationwide . Not too shabby, when you compare that to the industry average acceptance rate of 3%.

1. The key to landing your consulting job.

Case interviews - where you are asked to solve a business case study under scrutiny - are the core of the selection process right across McKinsey, Bain and BCG (the “MBB” firms). This interview format is also used pretty much universally across other high-end consultancies; including LEK, Kearney, Oliver Wyman and the consulting wings of the “Big Four”.

If you want to land a job at any of these firms, you will have to ace multiple case interviews.

It is increasingly likely that you will also have to solve online cases given by chatbots. You might need to pass these either before making it to interview or be asked to sit them alongside first round interviews.

Importantly, case studies aren’t something you can just wing . Firms explicitly expect you to have thoroughly prepared and many of your competitors on interview day will have been prepping for months.

Don’t worry though - MCC is here to help!

This article will take you through a full overview of everything you’ll need to know to do well, linking to more detailed articles and resources at each stage to let you really drill down into the details.

As well as traditional case interviews, we’ll also attend to the new formats in which cases are being delivered and otherwise make sure you’re up to speed with recent trends in this overall part of consulting recruitment.

Before we can figure out how to prepare for a case interview, though, we will first have to properly understand in detail what exactly you are up against. What format does a standard consulting case interview take? What is expected of you? How will you be assessed?

2. What is a case interview?

Before we can hope to tackle a case interview, we have to understand what one is.

In short, a case interview simulates real consulting work by having you solve a business case study in conversation with your interviewer.

This case study will be a business problem where you have to advise a client - that is, an imaginary business or similar organisation in need of guidance.

You must help this client solve a problem and/or make a decision. This requires you to analyse the information you are given about that client organisation and figure out a final recommendation for what they should do next.

Business problems in general obviously vary in difficulty. Some are quite straightforward and can be addressed with fairly standard solutions. However, consulting firms exist precisely to solve the tough issues that businesses have failed to deal with internally - and so consultants will typically work on complex, idiosyncratic problems requiring novel solutions.

Some examples of case study questions might be:

• How much would you pay for a banking licence in Ghana?
• Estimate the potential value of the electric vehicle market in Germany
• How much gas storage capacity should a UK domestic energy supplier build?

Consulting firms need the brightest minds they can find to put to work on these important, difficult projects. You can expect the case studies you have to solve in interview, then, to echo the unique, complicated problems consultancies deal with every day. As we’ll explain here, this means that you need to be ready to think outside the box to figure out genuinely novel solutions.

2.1. Where are case interviews in the consulting selection process?

Not everyone who applies to a consulting firm will have a case interview - far from it!

In fact, case interviews are pretty expensive and inconvenient for firms to host, requiring them to take consultants off active projects and even fly them back to the office from location for in-person interviews (although this happens less frequently now). Ideally, firms want to cut costs and save time by narrowing down the candidate pool as much as possible before any live interviews.

As such, there are some hoops to jump through before you make it to interview rounds.

Firms will typically eliminate as much as 80% of the applicant pool before interviews start . For most firms, 50%+ of applicants might be cut based on resumes, before a similar cut is made on those remaining based on aptitude tests. McKinsey currently gives their Solve assessment to most applicants, but will use their resulting test scores alongside resumes to cut 70%+ of the candidate pool before interviews.

You'll need to be on top of your game to get as far as a case interview with a top firm. Getting through the resume screen and any aptitude tests is an achievement in itself! Also we need to note that the general timeline of an application can differ depending on a series of factors, including which position you apply, your background, and the office you are applying to. For example, an undergraduate applying for a Business Analyst position (the entry level job at McKinsey) will most likely be part of a recruitment cycle and as such have pretty fixed dates when they need to sit the pre-screening test, and have the first and second round interviews (see more on those below). Conversely, an experienced hire will most likely have a much greater choice of test and interview dates as well as more time at their disposal to prepare.

For readers not yet embroiled in the selection process themselves, let’s put case interviews in context and take a quick look at each stage in turn. Importantly, note that you might also be asked to solve case studies outside interviews as well…

2.1.1. Application screen

It’s sometimes easy to forget that such a large cut is made at the application stage. At larger firms, this will mean your resume and cover letter is looked at by some combination of AI tools, recruitment staff and junior consulting staff (often someone from your own university).

Only the best applications will be passed to later stages, so make sure to check out our free resume and cover letter guides, and potentially get help with editing , to give yourself the best chance possible.

2.1.2. Aptitude tests and online cases

This part of the selection process has been changing quickly in recent years and is increasingly beginning to blur into the traditionally separate case interview rounds.

In the past, GMAT or PST style tests were the norm. Firms then used increasingly sophisticated and often gamified aptitude tests, like the Pymetrics test currently used by several firms, including BCG and Bain, and the original version of McKinsey’s Solve assessment (then branded as the Problem Solving Game).

Now, though, there is a move towards delivering relatively sophisticated case studies online. For example, McKinsey has replaced half the old Solve assessment with an online case. BCG’s Casey chatbot case now directly replaces a live first round case interview, and in the new era of AI chatbots, we expect these online cases to quickly become more realistic and increasingly start to relieve firms of some of the costs of live case interviews.

Our consultants collectively reckon that, over time, 50% of case interviews are likely to be replaced with these kinds of cases . We give some specific advice for online cases in section six. However, the important thing to note is that these are still just simulations of traditional case interviews - you still need to learn how to solve cases in precisely the same way, and your prep will largely remain the same.

2.1.3. Rounds of Interviews

Now, let’s not go overboard with talk of AI. Even in the long term, the client facing nature of consulting means that firms will have live case interviews for as long as they are hiring anyone. And in the immediate term, case interviews are still absolutely the core of consulting selection.

Before landing an offer at McKinsey, Bain, BCG or any similar firm, you won’t just have one case interview, but will have to complete four to six case interviews, usually divided into two rounds, with each interview lasting approximately 50-60 minutes .

Being invited to first round usually means two or three case interviews. As noted above, you might also be asked to complete an online case or similar alongside your first round interviews.

If you ace first round, you will be invited to second round to face the same again, but more gruelling. Only then - after up to six case interviews in total, can you hope to receive an offer.

2.2. Differences between first and second round interviews

Despite case interviews in the first and second round following the same format, second/final round interviews will be significantly more intense . The seniority of the interviewer, time pressure (with up to three interviews back-to-back), and the sheer value of the job at stake will likely make a second round consulting case interview one of the most challenging moments of your professional life.

There are three key differences between the two rounds:

• Time Pressure : Final round case interviews test your ability to perform under pressure, with as many as three interviews in a row and often only very small breaks between them.
• Focus : Since second round interviewers tend to be more senior (usually partners with 12+ years experience) and will be more interested in your personality and ability to handle challenges independently. Some partners will drill down into your experiences and achievements to the extreme. They want to understand how you react to challenges and your ability to identify and learn from past mistakes.
• Psychological Pressure: While case interviews in the first round are usually more focused on you simply cracking the case, second round interviewers often employ a "bad cop" strategy to test the way you react to challenges and uncertainty.

2.3. What skills do case interviews assess?

Reliably impressing your interviewers means knowing what they are looking for. This means understanding the skills you are being assessed against in some detail.

Overall, it’s important always to remember that, with case studies, there are no strict right or wrong answers. What really matters is how you think problems through, how confident you are with your conclusions and how quick you are with the back of the envelope arithmetic.

The objective of this kind of interview isn’t to get to one particular solution, but to assess your skillset. This is even true of modern online cases, where sophisticated AI algorithms score how you work as well as the solutions you generate.

If you visit McKinsey , Bain and BCG web pages on case interviews, you will find that the three firms look for very similar traits, and the same will be true of other top consultancies.

Broadly speaking, your interviewer will be evaluating you across five key areas:

2.1.1.One: Probing mind

Showing intellectual curiosity by asking relevant and insightful questions that demonstrate critical thinking and a proactive nature. For instance, if we are told that revenues for a leading supermarket chain have been declining over the last ten years, a successful candidate would ask:

“ We know revenues have declined. This could be due to price or volume. Do we know how they changed over the same period? ”

This is as opposed to a laundry list of questions like:

• Did customers change their preferences?
• Which segment has shown the decline in volume?
• Is there a price war in the industry?

2.1.2. Structure

Structure in this context means structuring a problem. This, in turn, means creating a framework - that is, a series of clear, sequential steps in order to get to a solution.

As with the case interview in general, the focus with case study structures isn’t on reaching a solution, but on how you get there.

This is the trickiest part of the case interview and the single most common reason candidates fail.

We discuss how to properly structure a case in more detail in section three. In terms of what your interviewer is looking for at high level, though, key pieces of your structure should be:

• Proper understanding of the objective of the case - Ask yourself: "What is the single crucial piece of advice that the client absolutely needs?"
• Identification of the drivers - Ask yourself: "What are the key forces that play a role in defining the outcome?"

Our Problem Driven Structure method, discussed in section three, bakes this approach in at a fundamental level. This is as opposed to the framework-based approach you will find in older case-solving

Focus on going through memorised sequences of steps too-often means failing to develop a full understanding of the case and the real key drivers.

At this link, we run through a case to illustrate the difference between a standard framework-based approach and our Problem Driven Structure method.

2.1.3. Problem Solving

You’ll be tested on your ability to identify problems and drivers, isolate causes and effects, demonstrate creativity and prioritise issues. In particular, the interviewer will look for the following skills:

• Prioritisation - Can you distinguish relevant and irrelevant facts?
• Connecting the dots - Can you connect new facts and evidence to the big picture?
• Establishing conclusions - Can you establish correct conclusions without rushing to inferences not supported by evidence?

2.1.4. Numerical Agility

In case interviews, you are expected to be quick and confident with both precise and approximated numbers. This translates to:

• Performing simple calculations quickly - Essential to solve cases quickly and impress clients with quick estimates and preliminary conclusions.
• Analysing data - Extract data from graphs and charts, elaborate and draw insightful conclusions.
• Solving business problems - Translate a real world case to a mathematical problem and solve it.

Our article on consulting math is a great resource here, though the extensive math content in our MCC Academy is the best and most comprehensive material available.

2.1.5. Communication

Real consulting work isn’t just about the raw analysis to come up with a recommendation - this then needs to be sold to the client as the right course of action.

Similarly, in a case interview, you must be able to turn your answer into a compelling recommendation. This is just as essential to impressing your interviewer as your structure and analysis.

Consultants already comment on how difficult it is to find candidates with the right communication skills. Add to this the current direction of travel, where AI will be able to automate more and more of the routine analytic side of consulting, and communication becomes a bigger and bigger part of what consultants are being paid for.

So, how do you make sure that your recommendations are relevant, smart, and engaging? The answer is to master what is known as CEO-level communication .

This art of speaking like a CEO can be quite challenging, as it often involves presenting information in effectively the opposite way to how you might normally.

To get it right, there are three key areas to focus on in your communications:

• Top down : A CEO wants to hear the key message first. They will only ask for more details if they think that will actually be useful. Always consider what is absolutely critical for the CEO to know, and start with that. You can read more in our article on the Pyramid Principle .
• Concise : This is not the time for "boiling the ocean" or listing an endless number possible solutions. CEOs, and thus consultants, want a structured, quick and concise recommendation for their business problem, that they can implement immediately.
• Fact-based : Consultants share CEOs' hatred of opinions based on gut feel rather than facts. They want recommendations based on facts to make sure they are actually in control. Always go on to back up your conclusions with the relevant facts.

Being concise and to the point is key in many areas, networking being one for them. For more detail on all this, check out our full article on delivering recommendations .

Prep the right way

3. types of case interview.

While most case interviews share a similar structure, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

As we’ll see, these differences aren’t hugely impactful in terms of how you prepare. That said, it's always good to know as much as possible about what you will be going up against.

3.1. Different case objectives

A guiding thread throughout this article and our approach in general will be to treat each case as a self-contained problem and not try to pigeonhole it into a certain category. Having said that, there are of course similarities between cases and we can identify certain parameters and objectives.

Broadly speaking, cases can be divided into issue-based cases and strategic decision cases. In the former you will be asked to solve a certain issue, such as declining profits, or low productivity whereas in the latter you will be ask whether your client should or should not do something, such as enter a specific market or acquire another company. The chart below is a good breakdown of these different objectives:

3.2. How do interviewers craft cases

While interviewers will very likely be given a case bank to choose from by their company, a good number of them will also choose to adapt the cases they would currently be working on to a case interview setting. The difference is that the latter cases will be harder to pigeonhole and apply standard frameworks to, so a tailored approach will be paramount.

If you’ve applied for a specific practice or type of consulting - such as operational consulting, for example - it’s very likely that you will receive a case geared towards that particular area alongside a ‘generalist’ consulting case (however, if that’s the case, you will generally be notified). The other main distinction when it comes to case interviews is between interviewer-led and candidate-led.

3.3. Candidate-led cases

Most consulting case interview questions test your ability to crack a broad problem, with a case prompt often going something like:

" How much would you pay to secure the rights to run a restaurant in the British Museum? "

You, as a candidate, are then expected to identify your path to solve the case (that is, provide a structure), leveraging your interviewer to collect the data and test your assumptions.

This is known as a “candidate-led” case interview and is used by Bain, BCG and other firms. From a structuring perspective, it’s easier to lose direction in a candidate-led case as there are no sign-posts along the way. As such, you need to come up with an approach that is both broad enough to cover all of the potential drivers in a case but also tailored enough to the problem you are asked to solve. It’s also up to you to figure out when you need to delve deeper into a certain branch of the case, brainstorm or ask for data. The following case from Bain is an excellent example on how to navigate a candidate-led case.

3.4. Interviewer-led cases

This type of case - employed most famously by McKinsey - is slightly different, with the interviewer controlling the pace and direction of the conversation much more than with other case interviews.

At McKinsey, your interviewer will ask you a set of pre-determined questions, regardless of your initial structure. For each question, you will have to understand the problem, come up with a mini structure, ask for additional data (if necessary) and come to the conclusion that answers the question. This more structured format of case also shows up in online cases by other firms - notably including BCG’s Casey chatbot (with the amusing result that practising McKinsey-style cases can be a great addition when prepping for BCG).

Essentially, these interviewer-led case studies are large cases made up of lots of mini-cases. You still use basically the same method as you would for standard (or candidate-led) cases - the main difference is simply that, instead of using that method to solve one big case, you are solving several mini-cases sequentially. These cases are easier to follow as the interviewer will guide you in the right direction. However, this doesn’t mean you should pay less attention to structure and deliver a generic framework! Also, usually (but not always!) the first question will ask you to map your approach and is the equivalent of the structuring question in candidate-led cases. Sometimes, if you’re missing key elements, the interviewer might prompt you in the right direction - so make sure to take those prompts seriously as they are there to help you get back on track (ask for 30 seconds to think on the prompt and structure your approach). Other times - and this is a less fortunate scenario - the interviewer might say nothing and simply move on to the next question. This is why you should put just as much thought (if not more) into the framework you build for interviewer-led cases , as you may be penalized if you produce something too generic or that doesn’t encompass all the issues of the case.

3.5. Case and fit

The standard case interview can be thought of as splitting into two standalone sub-interviews. Thus “case interviews” can be divided into the case study itself and a “fit interview” section, where culture fit questions are asked.

This can lead to a bit of confusion, as the actual case interview component might take up as little as half of your scheduled “case interview”. You need to make sure you are ready for both aspects.

To illustrate, here is the typical case interview timeline:

• First 15-30 minutes: Fit Interview - with questions assessing your motivation to be a consultant in that specific firm and your traits around leadership and teamwork. Learn more about the fit interview in our in-depth article here .
• Next 30-40 minutes: Case Interview - solving a case study
• Last 5 minutes: Fit Interview again - this time focussing on your questions for your interviewer.

Both the Case and Fit interviews play crucial roles in the finial hiring decision. There is no “average” taken between case and fit interviews: if your performance is not up to scratch in either of the two, you will not be able to move on to the next interview round or get an offer.

NB: No case without fit

Note that, even if you have only been told you are having a case interview or otherwise are just doing a case study, always be prepared to answer fit questions. At most firms, it is standard practice to include some fit questions in all case interviews, even if there are also separate explicit fit interviews, and interviewers will almost invariably include some of these questions around your case. This is perfectly natural - imagine how odd and artificial it would be to show up to an interview, simply do a case and leave again, without talking about anything else with the interviewer before or after.

3.5.1 Differences between firms

For the most part, a case interview is a case interview. However, firms will have some differences in the particular ways they like to do things in terms of both the case study and the fit component.

3.5.2. The McKinsey PEI

McKinsey brands its fit aspect of interviews as the Personal Experience Interview or PEI. Despite the different name, this is really much the same interview you will be going up against in Bain, BCG and any similar firms.

McKinsey does have a reputation for pushing candidates a little harder with fit or PEI questions , focusing on one story per interview and drilling down further into the specific details each time. We discuss this tendency more in our fit interview article . However, no top end firm is going to go easy on you and you should absolutely be ready for the same level of grilling at Bain, BCG and others. Thus any difference isn’t hugely salient in terms of prep.

3.6. What is different in 2023?

For the foreseeable future, you are going to have to go through multiple live case interviews to secure any decent consulting job. These might increasingly happen via Zoom rather than in person, but they should remain largely the same otherwise.

However, things are changing and the rise of AI in recent months seems pretty much guaranteed to accelerate existing trends.

Even before the explosive development of AI chatbots like ChatGPT we have seen in recent months, automation was already starting to change the recruitment process.

As we mentioned, case interviews are expensive and inconvenient for firms to run . Ideally, then, firms will try to reduce the number of interviews required for recruitment as far as possible. For many years, tests of various kinds served to cut down the applicant pool and thus the number of interviews. However, these tests had a limited capacity to assess candidates against the full consulting skillset in the way that case interviews do so well.

More recently, though, the development of online testing has allowed for more and more advanced assessments. Top consulting firms have been leveraging screening tests that better and better capture the same skillset as case interviews. Eventually this is converging on automated case studies. We see this very clearly with the addition of the Redrock case to McKinsey’s Solve assessment.

As these digital cases become closer to the real thing, the line between test and case interview blurs. Online cases don’t just reduce the number of candidates to case interview, but start directly replacing them.

Case in point here is BCG’s Casey chatbot . Previously, BCG had deployed less advanced online cases and similar tests to weed out some candidates before live case interviews began. Now, though, Casey actually replaces one first round case interview.

Casey, at time of writing, is still a relatively “basic” chatbot, basically running through a pre-set script. The Whatsapp-like interface does a lot of work to make it feel like one is chatting to a “real person” - the chatbot itself, though, cannot provide feedback or nudges to candidates as would a human interviewer.

We fully expect that, as soon as BCG and other firms can train a truer AI, these online cases will become more widespread and start replacing more live interviews.

We discuss the likely impacts of advanced AI on consulting recruitment and the industry more broadly in our blog.

Here, though, the real message is that you should expect to run into digital cases as well as traditional case interviews.

Luckily, despite any changes in specific case interview format, you will still need to master the same fundamental skills and prepare in much the same way.

We’ll cover a few ways to help prepare for chatbot cases in section four. Ultimately, though, firms are looking for the same problem solving ability and mindset as a real interviewer. Especially as chatbots get better at mimicking a real interviewer, candidates who are well prepared for case cracking in general should have no problem with AI administered cases.

3.6.1. Automated fit interviews

Analogous to online cases, in recent years there has been a trend towards automated, “one way” fit interviews, with these typically being administered for consultancies by specialist contractors like HireVue or SparkHire.

These are kind of like Zoom interviews, but if the interviewer didn’t show up. Instead you will be given fit questions to answer and must record your answer in your computer webcam. Your response will then go on to be assessed by an algorithm, scoring both what you say and how you say it.

Again, with advances in AI, it is easy to imagine these automated case interviews going from fully scripted interactions, where all candidates are asked the same list of questions, to a more interactive experience. Thus, we might soon arrive at a point where you are being grilled on the details of your stories - McKinsey PEI style - but by a bot rather than a human.

We include some tips on this kind of “one way” fit interview in section six here.

4. How to solve cases with the Problem-Driven Structure?

If you look around online for material on how to solve case studies, a lot of what you find will set out framework-based approaches. However, as we have mentioned, these frameworks tend to break down with more complex, unique cases - with these being exactly the kind of tough case studies you can expect to be given in your case interviews.

To address this problem, the MyConsultingCoach team has synthesized a new approach to case cracking that replicates how top management consultants approach actual engagements.

MyConsultingCoach’s Problem Driven Structure approach is a universal problem solving method that can be applied to any business problem , irrespective of its nature.

As opposed to just selecting a generic framework for each case interview, the Problem Driven Structure approach works by generating a bespoke structure for each individual question and is a simplified version of the roadmap McKinsey consultants use when working on engagements.

The canonical seven steps from McKinsey on real projects are simplified to four for case interview questions, as the analysis required for a six-month engagement is somewhat less than that needed for a 45-minute case study. However, the underlying flow is the same (see the method in action in the video below)

Let's zoom in to see how our method actually works in more detail:

4.1. Identify the problem

Identifying the problem means properly understanding the prompt/question you are given, so you get to the actual point of the case.

This might sound simple, but cases are often very tricky, and many candidates irretrievably mess things up within the first few minutes of starting. Often, they won’t notice this has happened until they are getting to the end of their analysis. Then, they suddenly realise that they have misunderstood the case prompt - and have effectively been answering the wrong question all along!

With no time to go back and start again, there is nothing to do. Even if there were time, making such a silly mistake early on will make a terrible impression on their interviewer, who might well have written them off already. The interview is scuppered and all the candidate’s preparation has been for nothing.

This error is so galling as it is so readily avoidable.

Our method prevents this problem by placing huge emphasis on a full understanding of the case prompt. This lays the foundations for success as, once we have identified the fundamental, underlying problem our client is facing, we focus our whole analysis around finding solutions to this specific issue.

Now, some case interview prompts are easy to digest. For example, “Our client, a supermarket, has seen a decline in profits. How can we bring them up?”. However, many of the prompts given in interviews for top firms are much more difficult and might refer to unfamiliar business areas or industries. For example, “How much would you pay for a banking license in Ghana?” or “What would be your key areas of concern be when setting up an NGO?”

Don’t worry if you have no idea how you might go about tackling some of these prompts!

In our article on identifying the problem and in our full lesson on the subject in our MCC Academy course, we teach a systematic, four step approach to identifying the problem , as well as running through common errors to ensure you start off on the right foot every time!

This is summarised here:

Following this method lets you excel where your competitors mess up and get off to a great start in impressing your interviewer!

4.2. Build your problem driven structure

After you have properly understood the problem, the next step is to successfully crack a case is to draw up a bespoke structure that captures all the unique features of the case.

This is what will guide your analysis through the rest of the case study and is precisely the same method used by real consultants working on real engagements.

Of course, it might be easier here to simply roll out one an old-fashioned framework, and a lot of candidates will do so. This is likely to be faster at this stage and requires a lot less thought than our problem-driven structure approach.

However, whilst our problem driven structure approach requires more work from you, our method has the advantage of actually working in the kind of complex case studies where generic frameworks fail - that is exactly the kind of cases you can expect at an MBB interview .

Since we effectively start from first principles every time, we can tackle any case with the same overarching method. Simple or complex, every case is the same to you and you don’t have to gamble a job on whether a framework will actually work

4.2.1 Issue trees

Issue trees break down the overall problem into a set of smaller problems that you can then solve individually. Representing this on a diagram also makes it easy for both you and your interviewer to keep track of your analysis.

To see how this is done, let’s look at the issue tree below breaking down the revenues of an airline:

These revenues can be segmented as the number of customers multiplied by the average ticket price. The number of customers can be further broken down into a number of flights multiplied by the number of seats, times average occupancy rate. The node corresponding to the average ticket price can then be segmented further.

4.2.2 Hypothesis trees

Hypothesis trees are similar, the only difference being that rather than just trying to break up the issue into smaller issues you are assuming that the problem can be solved and you are formulating solutions.

In the example above, you would assume revenues can be increased by either increasing the average ticket price or the number of customers . You can then hypothesize that you can increase the average occupancy rate in three ways: align the schedule of short and long haul flights, run a promotion to boost occupancy in off-peak times, or offer early bird discounts.

4.2.3 Other structures:structured lists

Structured lists are simply subcategories of a problem into which you can fit similar elements. This McKinsey case answer starts off by identifying several buckets such as retailer response, competitor response, current capabilities and brand image and then proceeds to consider what could fit into these categories.

Buckets can be a good way to start the structure of a complex case but when using them it can be very difficult to be MECE and consistent, so you should always aim to then re-organize them into either an issue or a hypothesis tree.

It is worth noting that the same problem can be structured in multiple valid ways by choosing different means to segment the key issues. Ultimately all these lists are methods to set out a logical hierachy among elements.

4.2.4 Structures in practice

That said, not all valid structures are equally useful in solving the underlying problem. A good structure fulfils several requirements - including MECE-ness , level consistency, materiality, simplicity, and actionability. It’s important to put in the time to master segmentation, so you can choose a scheme isn’t only valid, but actually useful in addressing the problem.

After taking the effort to identify the problem properly, an advantage of our method is that it will help ensure you stay focused on that same fundamental problem throughout. This might not sound like much, but many candidates end up getting lost in their own analysis, veering off on huge tangents and returning with an answer to a question they weren’t asked.

Another frequent issue - particularly with certain frameworks - is that candidates finish their analysis and, even if they have successfully stuck to the initial question, they have not actually reached a definite solution. Instead, they might simply have generated a laundry list of pros and cons, with no clear single recommendation for action.

Clients employ consultants for actionable answers, and this is what is expected in the case interview. The problem driven structure excels in ensuring that everything you do is clearly related back to the key question in a way that will generate a definitive answer. Thus, the problem driven structure builds in the hypothesis driven approach so characteristic of real consulting practice.

You can learn how to set out your own problem driven structures in our article here and in our full lesson in the MCC Academy course.

4.2. Lead the analysis

A problem driven structure might ensure we reach a proper solution eventually, but how do we actually get there?

We call this step " leading the analysis ", and it is the process whereby you systematically navigate through your structure, identifying the key factors driving the issue you are addressing.

Generally, this will mean continuing to grow your tree diagram, further segmenting what you identify as the most salient end nodes and thus drilling down into the most crucial factors causing the client’s central problem.

Once you have gotten right down into the detail of what is actually causing the company’s issues, solutions can then be generated quite straightforwardly.

To see this process in action, we can return to our airline revenue example:

Let’s say we discover the average ticket price to be a key issue in the airline’s problems. Looking closer at the drivers of average ticket price, we find that the problem lies with economy class ticket prices. We can then further segment that price into the base fare and additional items such as food.

Having broken down the issue to such a fine-grained level and considering the 80/20 rule(see below), solutions occur quite naturally. In this case, we can suggest incentivising the crew to increase onboard sales, improving assortment in the plane, or offering discounts for online purchases.

Our article on leading the analysis is a great primer on the subject, with our video lesson in the MCC Academy providing the most comprehensive guide available.

4.4. Provide recommendations

So you have a solution - but you aren’t finished yet!

Now, you need to deliver your solution as a final recommendation.

This should be done as if you are briefing a busy CEO and thus should be a one minute, top-down, concise, structured, clear, and fact-based account of your findings.

The brevity of the final recommendation belies its importance. In real life consulting, the recommendation is what the client has potentially paid millions for - from their point of view, it is the only thing that matters.

In a case interview, your performance in this final summing up of your case is going to significantly colour your interviewer’s parting impression of you - and thus your chances of getting hired!

So, how do we do it right?

Barbara Minto's Pyramid Principle elegantly sums up almost everything required for a perfect recommendation. The answer comes first , as this is what is most important. This is then supported by a few key arguments , which are in turn buttressed by supporting facts .

Across the whole recommendation, the goal isn’t to just summarise what you have done. Instead, you are aiming to synthesize your findings to extract the key "so what?" insight that is useful to the client going forward.

All this might seem like common sense, but it is actually the opposite of how we relay results in academia and other fields. There, we typically move from data, through arguments and eventually to conclusions. As such, making good recommendations is a skill that takes practice to master.

We can see the Pyramid Principle illustrated in the diagram below:

To supplement the basic Pyramid Principle scheme, we suggest candidates add a few brief remarks on potential risks and suggested next steps . This helps demonstrate the ability for critical self-reflection and lets your interviewer see you going the extra mile.

The combination of logical rigour and communication skills that is so definitive of consulting is particularly on display in the final recommendation.

Despite it only lasting 60 seconds, you will need to leverage a full set of key consulting skills to deliver a really excellent recommendation and leave your interviewer with a good final impression of your case solving abilities.

Our specific article on final recommendations and the specific video lesson on the same topic within our MCC Academy are great, comprehensive resources. Beyond those, our lesson on consulting thinking and our articles on MECE and the Pyramid Principle are also very useful.

4.5. What if I get stuck?

Naturally with case interviews being difficult problems there may be times where you’re unsure what to do or which direction to take. The most common scenario is that you will get stuck midway through the case and there are essentially two things that you should do:

• 1. Go back to your structure
• 2. Ask the interviewer for clarification

Your structure should always be your best friend - after all, this is why you put so much thought and effort into it: if it’s MECE it will point you in the right direction. This may seem abstract but let’s take the very simple example of a profitability case interview: if you’ve started your analysis by segmenting profit into revenue minus costs and you’ve seen that the cost side of the analysis is leading you nowhere, you can be certain that the declining profit is due to a decline in revenue.

Similarly, when you’re stuck on the quantitative section of the case interview, make sure that your framework for calculations is set up correctly (you can confirm this with the interviewer) and see what it is you’re trying to solve for: for example if you’re trying to find what price the client should sell their new t-shirt in order to break even on their investment, you should realize that what you’re trying to find is the break even point, so you can start by calculating either the costs or the revenues. You have all the data for the costs side and you know they’re trying to sell 10.000 pairs so you can simply set up the equation with x being the price.

As we’ve emphasised on several occasions, your case interview will be a dialogue. As such, if you don’t know what to do next or don’t understand something, make sure to ask the interviewer (and as a general rule always follow their prompts as they are trying to help, not trick you). This is especially true for the quantitative questions, where you should really understand what data you’re looking at before you jump into any calculations. Ideally you should ask your questions before you take time to formulate your approach but don’t be afraid to ask for further clarification if you really can’t make sense of what’s going on. It’s always good to walk your interviewer through your approach before you start doing the calculations and it’s no mistake to make sure that you both have the same understanding of the data. For example when confronted with the chart below, you might ask what GW (in this case gigawatt) means from the get-go and ask to confirm the different metrics (i.e. whether 1 GW = 1000 megawatts). You will never be penalised for asking a question like that.

5. What to remember in case interviews

If you’re new to case cracking you might feel a bit hopeless when you see a difficult case question, not having any idea where to start.

In fact though, cracking case interviews is much like playing chess. The rules you need to know to get started are actually pretty simple. What will make you really proficient is time and practice.

In this section, we’ll run through a high level overview of everything you need to know, linking to more detailed resources at every step.

5.1. An overall clear structure

You will probably hear this more than you care for but it is the most important thing to keep in mind as you start solving cases, as not only it is a key evaluation criterion but the greatest tool you will have at your disposal. The ability to build a clear structure in all aspects of the case inteview will be the difference between breezing through a complicated case and struggling at its every step. Let’s look a bit closer at the key areas where you should be structured!

5.1.1 Structured notes

Every case interview starts with a prompt, usually verbal, and as such you will have to take some notes. And here is where your foray into structure begins, as the notes you take should be clear, concise and structured in a way that will allow you to repeat the case back to the interviewer without writing down any unnecessary information.

This may sound very basic but you should absolutely not be dismissive about it: taking clear and organized notes will allow what we found helps is to have separate sections for:

• The case brief
• Follow-up questions and answers
• Numerical data
• Case structure (the most crucial part when solving the case)
• Any scrap work during the case (usually calculations)

When solving the case - or, as we call it here, in the Lead the analysis step, it is highly recommended to keep on feeding and integrating your structure, so that you never get lost. Maintaining a clear high level view is one of the most critical aspects in case interviews as it is a key skill in consulting: by constantly keeping track of where you are following your structure, you’ll never lose your focus on the end goal.

In the case of an interviewer-led case, you can also have separate sheets for each question (e.g. Question 1. What factors can we look at that drive profitability?). If you develop a system like this you’ll know exactly where to look for each point of data rather than rummage around in untidy notes. There are a couple more sections that you may have, depending on preference - we’ll get to these in the next sections.

5.1.2 Structured communication

There will be three main types of communication in cases:

• 1. Asking and answering questions
• 2. Walking the interviewer through your structure (either the case or calculation framework - we’ll get to that in a bit!)
• 3. Delivering your recommendation

Asking and answering questions will be the most common of these and the key thing to do before you speak is ask for some time to collect your thoughts and get organised. What you want to avoid is a ‘laundry list’ of questions or anything that sounds too much like a stream of consciousness.

Different systems work for different candidates but a sure-fire way of being organised is numbering your questions and answers. So rather than saying something like ‘I would like to ask about the business model, operational capacity and customer personas’ it’s much better to break it down and say something along the lines of ‘I’ve got three key questions. Firstly I would like to inquire into the business model of our client. Secondly I would like to ask about their operational capacity. Thirdly I would like to know more about the different customer personas they are serving’.

A similar principle should be applied when walking the interviewer through your structure, and this is especially true of online case interviews (more and more frequent now) when the interviewer can’t see your notes. Even if you have your branches or buckets clearly defined, you should still use a numbering system to make it obvious to the interviewer. So, for example, when asked to identify whether a company should make an acquisition, you might say ‘I would like to examine the following key areas. Firstly the financial aspects of this issue, secondly the synergies and thirdly the client’s expertise’

The recommendation should be delivered top-down (see section 4.4 for specifics) and should employ the same numbering principle. To do so in a speedy manner, you should circle or mark the key facts that you encounter throughout the case so you can easily pull them out at the end.

5.1.3 Structured framework

It’s very important that you have a systematic approach - or framework - for every case. Let’s get one thing straight: there is a difference between having a problem-solving framework for your case and trying to force a case into a predetermined framework. Doing the former is an absolute must , whilst doing the latter will most likely have you unceremoniously dismissed.

We have seen there are several ways of building a framework, from identifying several categories of issues (or ‘buckets’) to building an issue or hypothesis tree (which is the most efficient type of framework). For the purpose of organization, we recommend having a separate sheet for the framework of the case, or, if it’s too much to manage, you can have it on the same sheet as the initial case prompt. That way you’ll have all the details as well as your proposed solution in one place.

5.1.4 Structured calculations

Whether it’s interviewer or candidate-led, at some point in the case you will get a bunch of numerical data and you will have to perform some calculations (for the specifics of the math you’ll need on consulting interviews, have a look at our Consulting Math Guide ). Here’s where we urge you to take your time and not dive straight into calculating! And here’s why: while your numerical agility is sure to impress interviewers, what they’re actually looking for is your logic and the calculations you need to perform in order to solve the problem . So it’s ok if you make a small mistake, as long as you’re solving for the right thing.

As such, make it easy for them - and yourself. Before you start, write down in steps the calculations you need to perform. Here’s an example: let’s say you need to find out by how much profits will change if variable costs are reduced by 10%. Your approach should look something like:

• 1. Calculate current profits: Profits = Revenues - (Variable costs + Fixed costs)
• 2. Calculate the reduction in variable costs: Variable costs x 0.9
• 3. Calculate new profits: New profits = Revenues - (New variable costs + Fixed costs)

Of course, there may be more efficient ways to do that calculation, but what’s important - much like in the framework section - is to show your interviewer that you have a plan, in the form of a structured approach. You can write your plan on the sheet containing the data, then perform the calculations on a scrap sheet and fill in the results afterward.

5.2. Common business knowledge and formulas

Although some consulting firms claim they don’t evaluate candidates based on their business knowledge, familiarity with basic business concepts and formulae is very useful in terms of understanding the case studies you are given in the first instance and drawing inspiration for structuring and brainstorming.

If you are coming from a business undergrad, an MBA or are an experienced hire, you might well have this covered already. For those coming from a different background, it may be useful to cover some.

Luckily, you don’t need a degree-level understanding of business to crack case interviews , and a lot of the information you will pick up by osmosis as you read through articles like this and go through cases.

However, some things you will just need to sit down and learn. We cover everything you need to know in some detail in our Case Academy Course course. However, some examples here of things you need to learn are:

• Basic accounting (particularly how to understand all the elements of a balance sheet)
• Basic economics
• Basic marketing
• Basic strategy

Below we include a few elementary concepts and formulae so you can hit the ground running in solving cases. We should note that you should not memorise these and indeed a good portion of them can be worked out logically, but you should have at least some idea of what to expect as this will make you faster and will free up much of your mental computing power. In what follows we’ll tackle concepts that you will encounter in the private business sector as well as some situations that come up in cases that feature clients from the NGO or governmental sector.

5.2.1 Business sector concepts

These concepts are the bread and butter of almost any business case so you need to make sure you have them down. Naturally, there will be specificities and differences between cases but for the most part here is a breakdown of each of them.

5.2.1.1. Revenue

The revenue is the money that the company brings in and is usually equal to the number of products they sell multiplied to the price per item and can be expressed with the following equation:

Revenue = Volume x Price

Companies may have various sources of revenue or indeed multiple types of products, all priced differently which is something you will need to account for in your case interview. Let’s consider some situations. A clothing company such as Nike will derive most of their revenue from the number of products they sell times the average price per item. Conversely, for a retail bank revenue is measured as the volume of loans multiplied by the interest rate at which the loans are given out. As we’ll see below, we might consider primary revenues and ancillary revenues: in the case of a football club, we might calculate primary revenues by multiplying the number of tickets sold by the average ticket price, and ancillary revenues those coming from sales of merchandise (similarly, let’s say average t-shirt price times the number of t-shirts sold), tv rights and sponsorships.

These are but a few examples and another reminder that you should always aim to ask questions and understand the precise revenue structure of the companies you encounter in cases.

5.2.1.2. Costs

The costs are the expenses that a company incurs during its operations. Generally, they can be broken down into fixed and variable costs :

Costs = Fixed Costs + Variable Costs

As their name implies, fixed costs do not change based on the number of units produced or sold. For example, if you produce shoes and are renting the space for your factory, you will have to pay the rent regardless of whether you produce one pair or 100. On the other hand, variable costs depend on the level of activity, so in our shoe factory example they would be equivalent to the materials used to produce each pair of shoes and would increase the more we produce.

These concepts are of course guidelines used in order to simplify the analysis in cases, and you should be aware that in reality often the situation can be more complicated. However, this should be enough for case interviews. Costs can also be quasi-fixed, in that they increase marginally with volume. Take the example of a restaurant which has a regular staff, incurring a fixed cost but during very busy hours or periods they also employ some part-time workers. This cost is not exactly variable (as it doesn’t increase with the quantity of food produced) but also not entirely fixed, as the number of extra hands will depend on how busy the restaurant is. Fixed costs can also be non-linear in nature. Let’s consider the rent in the same restaurant: we would normally pay a fixed amount every month, but if the restaurant becomes very popular we might need to rent out some extra space so the cost will increase. Again, this is not always relevant for case interviews.

5.2.1.3. Profit and profit margin

The profit is the amount of money a company is left with after it has paid all of its expenses and can be expressed as follows:

Profit = Revenue - Costs

It’s very likely that you will encounter a profitability issue in one of your case interviews, namely you will be asked to increase a company’s profit. There are two main ways of doing this: increasing revenues and reducing costs , so these will be the two main areas you will have to investigate. This may seem simple but what you will really need to understand in a case are the key drivers of a business (and this should be done through clarifying questions to the interviewer - just as a real consultant would question their client).

For example, if your client is an airline you can assume that the main source of revenue is sales of tickets, but you should inquire how many types of ticket the specific airline sells. You may naturally consider economy and business class tickets, but you may find out that there is a more premium option - such as first class - and several in-between options. Similarly to our football club example, there may be ancillary revenues from selling of food and beverage as well as advertising certain products or services on flights.

You may also come across the profit margin in case interviews. This is simply the percentage of profit compared to the revenue and can be expressed as follows:

Profit margin = Profit/Revenue x 100

5.2.1.4. Break-even point

An ancillary concept to profit, the break-even point is the moment where revenues equal costs making the profit zero and can be expressed as the following equation:

Revenues = Costs (Fixed costs + Variable costs)

This formula will be useful when you are asked questions such as ‘What is the minimum price I should sell product X?’ or ‘What quantity do I need to sell in order to recoup my investment?’. Let’s say in a case interview an owner of a sandwich store asks us to figure out how many salami and cheese salami sandwiches she needs to sell in order to break even. She’s spending $4 on salami and $2 for cheese and lettuce per sandwich, and believes she can sell the sandwiches at around $7. The cost of utilities and personnel is around $5000 per month. We could lay this all out in the break-even equation:

7 x Q ( quantity ) = (4+2) x Q + 5000 ( variable + fixed costs )

In a different scenario, we may be asked to calculate the break-even price . Let’s consider our sandwich example and say our owner knows she has enough ingredients for about 5000 sandwiches per month but is not sure how much to sell them for. In that case, if we know our break-even equation, we can simply make the following changes:

P ( price ) x 5000 = (4+2) x 5000 + 5000

By solving the equation we get to the price of $7 per sandwich.

5.2.1.5. Market share and market size

We can also consider the market closely with profit, as in fact the company’s performance in the market is what drives profits. The market size is the total number of potential customers for a certain business or product, whereas the market share is the percentage of that market that your business controls (or could control, depending on the case).

There is a good chance you will have to estimate the market size in one of your case interviews and we get into more details on how to do that below. You may be asked to estimate this in either number of potential customers or total value . The latter simply refers to the number of customers multiplied by the average value of the product or service.

To calculate the market share you will have to divide the company’s share by the total market size and multiply by 100:

Note, though, that learning the very basics of business is the beginning rather than the end of your journey. Once you are able to “speak business” at a rudimentary level, you should try to “become fluent” and immerse yourself in reading/viewing/listening to as wide a variety of business material as possible, getting a feel for all kinds of companies and industries - and especially the kinds of problems that can come up in each context and how they are solved. The material put out by the consulting firms themselves is a great place to start, but you should also follow the business news and find out about different companies and sectors as much as possible between now and interviews. Remember, if you’re going to be a consultant, this should be fun rather than a chore!

5.3 Public sector and NGO concepts

As we mentioned, there will be some cases (see section 6.6 for a more detailed example) where the key performance indicators (or KPIs in short) will not be connected to profit. The most common ones will involve the government of a country or an NGO, but they can be way more diverse and require more thought and application of first principles. We have laid out a couple of the key concepts or KPIs that come up below

5.3.1 Quantifiability

In many such scenarios you will be asked to make an important strategic decision of some kind or to optimise a process. Of course these are not restricted to non-private sector cases but this is where they really come into their own as there can be great variation in the type of decision and the types of field.

While there may be no familiar business concepts to anchor yourself onto, a concept that is essential is quantifiability . This means, however qualitative the decision might seem, consultants rely on data so you should always aim to have aspects of a decision that can be quantified, even if the data doesn’t present itself in a straightforward manner.

Let’s take a practical example. Your younger sibling asks you to help them decide which university they should choose if they want to study engineering. One way to structure your approach would be to segment the problem into factors affecting your sibling’s experience at university and experience post-university. Within the ‘at uni’ category you might think about the following:

• Financials : How much are tuition costs and accommodation costs?
• Quality of teaching and research : How are possible universities ranked in the QS guide based on teaching and research?
• Quality of resources : How well stocked is their library, are the labs well equipped etc.?
• Subject ranking : How is engineering at different unis ranked?
• Life on campus and the city : What are the living costs in the city where the university is based? What are the extracurricular opportunities and would your sibling like to live in that specific city based on them?

Within the ‘out of uni’ category you might think about:

• Exit options : What are the fields in which your sibling could be employed and how long does it take the average student of that university to find a job?
• Alumni network : What percentage of alumni are employed by major companies?
• Signal : What percentage of applicants from the university get an interview in major engineering companies and related technical fields?

You will perhaps notice that all the buckets discussed pose quantifiable questions meant to provide us with data necessary to make a decision. It’s no point to ask ‘Which university has the nicest teaching staff?’ as that can be a very subjective metric.

5.3.1 Impact

Another key concept to consider when dealing with sectors other than the private one is how impactful a decision or a line of inquiry is on the overarching issue , or whether all our branches in our issue tree have a similar impact. This can often come in the form of impact on lives, such as in McKinsey’s conservation case discussed below, namely how many species can we save with our choice of habitat.

5.4 Common consulting concepts

Consultants use basic business concepts on an every day basis, as they help them articulate their frameworks to problems. However, they also use some consulting specific tools to quality check their analysis and perform in the most efficient way possible. These principles can be applied to all aspects of a consultant’s work, but for brevity we can say they mostly impact a consultant’s systematic approach and communication - two very important things that are also tested in case interviews. Therefore, it’s imperative that you not only get to know them, but learn how and when to use them as they are at the very core of good casing. They are MECE-ness, the Pareto Principle and the Pyramid principle and are explained briefly below - you should, however, go on to study them in-depth in their respective articles.

Perhaps the central pillar of all consulting work and an invaluable tool to solve cases, MECE stands for Mutually Exclusive and Collectively Exhaustive . It can refer to any and every aspect in a case but is most often used when talking about structure. We have a detailed article explaining the concept here , but the short version is that MECE-ness ensures that there is no overlap between elements of a structure (i.e. the Mutually Exclusive component) and that it covers all the drivers or areas of a problem (Collectively Exhaustive). It is a concept that can be applied to any segmentation when dividing a set into subsets that include it wholly but do not overlap.

Let’s take a simple example and then a case framework example. In simple terms, when we are asked to break down the set ‘cars’ into subsets, dividing cars into ‘red cars’ and ‘sports cars’ is neither mutually exclusive (as there are indeed red sports cars) nor exhaustive of the whole set (i.e. there are also yellow non-sports cars that are not covered by this segmentation). A MECE way to segment would be ‘cars produced before 2000’ and ‘cars produced after 2000’ as this segmentation allows for no overlap and covers all the cars in existence.

Dividing cars can be simple, but how can we ensure MECEness in a case-interview a.k.a. a business situation. While the same principles apply, a good tip to ensure that your structure is MECE is to think about all the stakeholders - i.e. those whom a specific venture involves.

Let’s consider that our client is a soda manufacturer who wants to move from a business-to-business strategy, i.e. selling to large chains of stores and supermarkets, to a business-to-consumer strategy where it sells directly to consumers. In doing so they would like to retrain part of their account managers as direct salespeople and need to know what factors to consider.

A stakeholder-driven approach would be to consider the workforce and customers and move further down the issue tree, thinking about individual issues that might affect them. In the case of the workforce, we might consider how the shift would affect their workload and whether it takes their skillset into account. As for the customers, we might wonder whether existing customers would be satisfied with this move: will the remaining B2B account managers be able to provide for the needs of all their clients and will the fact that the company is selling directly to consumers now not cannibalise their businesses? We see how by taking a stakeholder-centred approach we can ensure that every single perspective and potential issue arising from it is fully covered.

5.4.2 The Pareto Principle

Also known as the 80/20 rule, this principle is important when gauging the impact of a decision or a factor in your analysis. It simply states that in business (but not only) 80% of outcomes come from 20% of causes. What this means is you can make a few significant changes that will impact most of your business organisation, sales model, cost structure etc.

Let’s have a look at 3 quick examples to illustrate this:

• 80% of all accidents are caused by 20% of drivers
• 20% of a company’s products account for 80% of the sales
• 80% of all results in a company are driven by 20% of its employees

The 80/20 rule will be a very good guide line in real engagements as well as case interviews, as it will essentially point to the easiest and most straightforward way of doing things. Let’s say one of the questions in a case is asking you to come up with an approach to understand the appeal of a new beard trimmer. Obviously you can’t interview the whole male population so you might think about setting up a webpage and asking people to comment their thoughts. But what you would get would be a laundry list of difficult to sift through data.

Using an 80/20 approach you would segment the population based on critical factors (age groups, grooming habits etc.) and then approach a significant sample size of each (e.g. 20), analysing the data and reaching a conclusion.

5.4.3 The Pyramid Principle

This principle refers to organising your communication in a top-down , efficient manner. While this is generally applicable, the pyramid principle will most often be employed when delivering the final recommendation to your client. This means - as is implicit in the name - that you would organise your recommendation (and communication in general) as a pyramid, stating the conclusion or most important element at the top then go down the pyramid listing 3 supporting arguments and then further (ideally also 3) supporting arguments for those supporting arguments.

Let’s look at this in practice in a case interview context: your client is a German air-conditioning unit manufacturer who was looking to expand into the French market. However, after your analysis you’ve determined that the market share they were looking to capture would not be feasible. A final recommendation using the Pyramid Principle would sound something like this: ‘I recommend that we do not enter the German market for the following three reasons. Firstly, the market is too small for our ambitions of $50 million. Secondly the market is heavily concentrated, being controlled by three major players and our 5 year goal would amount to controlling 25% of the market, a share larger than that of any of the players. Thirdly, the alternative of going into the corporate market would not be feasible, as it has high barriers to entry.Then, if needed, we could delve deeper into each of our categories

6. Case examples or building blocks?

As we mentioned before, in your case interview preparation you will undoubtedly find preparation resources that claim that there are several standard types of cases and that there is a general framework that can be applied to each type of case. While there are indeed cases that are straightforward at least in appearance and seemingly invite the application of such frameworks, the reality is never that simple and cases often involve multiple or more complicated components that cannot be fitted into a simple framework.

At MCC we don’t want you to get into the habit of trying to identify which case type you’re dealing with and pull out a framework, but we do recognize that there are recurring elements in frameworks that are useful - such as the profitability of a venture (with its revenues and costs), the valuation of a business, estimating and segmenting a market and pricing a product.

We call these building blocks because they can be used to build case frameworks but are not a framework in and of themselves, and they can be shuffled around and rearranged in any way necessary to be tailored to our case. Hence, our approach is not to make you think in terms of case types but work from first principles and use these building blocks to build your own framework. Let’s take two case prompts to illustrate our point.

The first is from the Bain website, where the candidate is asked whether they think it’s a good idea for their friend to open a coffee shop in Cambridge UK (see the case here ). The answer framework provided here is a very straightforward profitability analysis framework, examining the potential revenues and potential costs of the venture:

While this is a good point to start for your case interview (especially taken together with the clarifying questions), we will notice that this approach will need more tailoring to the case - for example the quantity of coffee will be determined by the market for coffee drinkers in Cambridge, which we have to determine based on preference. We are in England so a lot of people will be drinking tea but we are in a university town so perhaps more people than average are drinking coffee as it provides a better boost when studying. All these are some much needed case-tailored hypotheses that we can make based on the initial approach.

Just by looking at this case we might be tempted to say that we can just take a profitability case and apply it without any issues. However, this generic framework is just a starting point and in reality we would need to tailor it much further in the way we had started to do in order to get to a satisfactory answer. For example, the framework for this specific case interview doesn’t cover aspects such as the customer’s expertise: does the friend have any knowledge of the coffee business, such as where to source coffee and how to prepare it? Also, we could argue there may be some legal factors to consider here, such as any approvals that they might need from the city council to run a coffee shop on site, or some specific trade licences that are not really covered in the basic profitability framework.

Let’s take a different case , however, from the McKinsey website. In this scenario, the candidate is being asked to identify some factors in order to choose where to focus the client’s conservation efforts. Immediately we can realise that this case doesn’t lend itself to any pre-packaged framework and we will need to come up with something from scratch - and take a look at McKinsey’s answer of the areas to focus on:

We notice immediately that this framework is 100% tailored to the case - of course there are elements which we encounter in other cases, such as costs and risks but again these are applied in an organic way. It’s pretty clear that while no standard framework would work in this case, the aforementioned concepts - costs and risks - and the way to approach them (a.k.a building blocks ) are fundamentally similar throughout cases (with the obvious specificities of each case).

In what follows, we’ll give a brief description of each building block starting from the Bain example discussed previously, in order to give you a general idea of what they are and their adaptability, but you should make sure to follow the link to the in-depth articles to learn all their ins and outs.

6.1 Estimates and segmentation

This building block will come into play mostly when you’re thinking about the market for a certain product (but make sure to read the full article for more details). Let’s take our Bain Cambridge coffee example. As we mentioned under the quantity bucket we need to understand what the market size for coffee in Cambridge would be - so we can make an estimation based on segmentation .

The key to a good estimation is the ability to logically break down the problem into more manageable pieces. This will generally mean segmenting a wider population to find a particular target group. We can start off with the population of Cambridge - which we estimate at 100.000. In reality the population is closer to 150.000 but that doesn’t matter - the estimation has to be reasonable and not accurate , so unless the interviewer gives you a reason to reconsider you can follow your instinct. We can divide that into people who do and don’t drink coffee. Given our arguments before, we can conclude that 80% of those, so 80.000 drink coffee. Then we can further segment into those who drink regularly - let’s say every day - and those who drink occasionally - let’s say once a week. Based on the assumptions before about the student population needing coffee to function, and with Cambridge having a high student population, we can assume that 80% of those drinking coffee are regular drinkers, so that would be 64.000 regular drinkers and 16.000 occasional drinkers. We can then decide whom we want to target what our strategy needs to be:

This type of estimation and segmentation can be applied to any case specifics - hence why it is a building block.

6.2 Profitability

We had several looks at this building block so far (see an in-depth look here ) as it will show up in most case interivew scenarios, since profit is a key element in any company’s strategy. As we have seen, the starting point to this analysis is to consider both the costs and revenues of a company, and try to determine whether revenues need to be improved or whether costs need to be lowered. In the coffee example, the revenues are dictated by the average price per coffe x the number of coffees sold , whereas costs can be split into fixed and variable .

Some examples of fixed costs would be the rent for the stores and the cost of the personnel and utilities, while the most obvious variable costs would be the coffee beans used and the takeaway containers (when needed). We may further split revenues in this case into Main revenues - i.e. the sales of coffee - and Ancillary revenues , which can be divided into Sales of food products (sales of pastries, sandwiches etc., each with the same price x quantity schema) and Revenues from events - i.e renting out the coffee shop to events and catering for the events themselves. Bear in mind that revenues will be heavily influenced by the penetration rate , i.e. the share of the market which we can capture.

6.3 Pricing

Helping a company determine how much they should charge for their goods or services is another theme that comes up frequently in cases. While it may seem less complicated than the other building blocks, we assure you it’s not - you will have to understand and consider several factors, such as the costs a company is incurring, their general strategic positioning, availability, market trends as well as the customers’ willingness to pay (or WTP in short) - so make sure to check out our in-depth guide here .

In our example, we may determine that the cost per cup (coffee beans, staff, rent) is £1. We want to be student friendly so we should consider how much students would want to pay for a coffee as well as how much are competitors are charging. Based on those factors, it would be reasonable to charge on average £2 per cup of coffee. It’s true that our competitors are charging £3 but they are targeting mostly the adult market, whose willingness to pay is higher, so their pricing model takes that into account as well as the lower volume of customers in that demographic.

6.4. Valuation

A variant of the pricing building block, a valuation problem generally asks the candidate to determine how much a client should pay for a specific company (the target of an acquisition) as well as what other factors to consider. The two most important factors (but not the only ones - for a comprehensive review see our Valuation article ) to consider are the net present value (in consulting interviews usually in perpetuity) and the synergies .

In short, the net present value of a company is how much profit it currently brings in, divided by how much that cash flow will depreciate in the future and can be represented with the equation below:

The synergies refer to what could be achieved should the companies operate as one, and can be divided into cost and revenue synergies .

Let’s expand our coffee example a bit to understand these. Imagine that our friend manages to open a chain of coffee shops in Cambridge and in the future considers acquiring a chain of take-out restaurants. The most straightforward example of revenue synergies would be cross-selling, in this case selling coffee in the restaurants as well as in the dedicated stores, and thus getting an immediate boost in market share by using the existing customers of the restaurant chain. A cost synergy would be merging the delivery services of the two businesses to deliver both food and coffee, thus avoiding redundancies and reducing costs associated with twice the number of drivers and vehicles.

6.5. Competitive interaction

This component of cases deals with situations where the market in which a company is operating changes and the company must decide what to do. These changes often have to do with a new player entering the market (again for more details make sure to dive into the Competitive Interaction article ).

Let’s assume that our Cambridge coffee shop has now become a chain and has flagged up to other competitors that Cambridge is a blooming market for coffee. As such, Starbucks has decided to open a few stores in Cambridge themselves, to test this market. The question which might be posed to a candidate is what should our coffee chain do. One way (and a MECE one) to approach the problem is to decide between doing something and doing nothing . We might consider merging with another coffee chain and pooling our resources or playing to our strengths and repositioning ourselves as ‘your student-friendly, shop around the corner’. Just as easily we may just wait the situation out and see whether indeed Starbucks is cutting into our market share - after all, the advantages of our product and services might speak for themselves and Starbucks might end up tanking. Both of these are viable options if argued right and depending on the further specifics of the case.

6.6. Special cases

Most cases deal with private sectors, where the overarching objective entails profit in some form. However, as hinted before, there are cases which deal with other sectors where there are other KPIs in place . The former will usually contain one or several of these building blocks whereas the latter will very likely have neither. This latter category is arguably the one that will stretch your analytical and organisational skills to the limit, since there will be very little familiarity that you can fall back on (McKinsey famously employs such cases in their interview process).

So how do we tackle the structure for such cases? The short answer would be starting from first principles and using the problem driven structure outlined above, but let’s look at a quick example in the form of a McKinsey case :

The first question addressed to the candidate is the following:

This is in fact asking us to build a structure for the case. So what should we have in mind here? Most importantly, we should start with a structure that is MECE and we should remember to do that by considering all the stakeholders . They are on the one hand the government and affiliated institutions and on the other the population. We might then consider which issues might arise for each shareholder and what the benefits for them would be, as well as the risks. This approach is illustrated in the answer McKinsey provides as well:

More than anything, this type of case shows us how important it is to practise and build different types of structures, and think about MECE ways of segmenting the problem.

7. How Do I prepare for case interviews

In consulting fashion, the overall preparation can be structured into theoretical preparation and practical preparation , with each category then being subdivided into individual prep and prep with a partner .

As a general rule, the level and intensity of the preparation will differ based on your background - naturally if you have a business background (and have been part of a consulting club or something similar) your preparation will be less intensive than if you’re starting from scratch. The way we suggest you go about it is to start with theoretical preparation , which means learning about case interviews, business and basic consulting concepts (you can do this using free resources - such as the ones we provide - or if you want a more through preparation you can consider joining our Case Academy as well).

You can then move on to the practical preparation which should start with doing solo cases and focusing on areas of improvement, and then move on to preparation with a partner , which should be another candidate or - ideally - an ex-consultant.

Let’s go into more details with respect to each type of preparation.

7.1. Solo practice

The two most important areas of focus in sole preparation are:

• Mental math

As we mentioned briefly, the best use of your time is to focus on solving cases. You can start with cases listed on MBB sites since they are clearly stated and have worked solutions as well (e.g. Bain is a good place to start) and then move to more complex cases (our Case Library also offers a range of cases of different complexities). To build your confidence, start out on easier case questions, work through with the solutions, and don't worry about time. As you get better, you can move on to more difficult cases and try to get through them more quickly. You should practice around eight case studies on your own to build your confidence.

Another important area of practice is your mental mathematics as this skill will considerably increase your confidence and is neglected by many applicants - much to their immediate regret in the case interview. Find our mental math tool here or in our course, and practice at least ten minutes per day, from day one until the day before the interview.

7.2. Preparation with a partner

There are aspects of a case interview - such as asking clarifying questions - which you cannot do alone and this is why, after you feel comfortable, you should move on to practice with another person. There are two options here:

• Practicing with a peer
• Practicing with an ex-consultant

In theory they can be complementary - especially if you’re peer is also preparing for consulting interviews - and each have advantages and disadvantages. A peer is likely to practice with you for free for longer, however you may end up reinforcing some bad habits or unable to get actionable feedback. A consultant will be able to provide you the latter but having their help for the same number of hours as a peer will come at a higher cost. Let’s look at each option in more detail.

7.2.1. Peer preparation

Once you have worked through eight cases solo, you should be ready to simulate the case interview more closely and start working with another person.

Here, many candidates turn to peer practice - that is, doing mock case interviews with friends, classmates or others also applying to consulting. If you’re in university, and especially in business school, there will very likely be a consulting club for you to join and do lots of case practice with. If you don’t have anyone to practice, though, or if you just want to get a bit more volume in with others, our free meeting board lets you find fellow applicants from around the world with whom to practice. We recommend practicing around 10 to 15 ‘live’ cases to really get to a point where you feel comfortable.

7.2.2. Preparation with a consultant

You can do a lot practising by yourself and with peers. However, nothing will bring up your skills so quickly and profoundly as working with a real consultant.

Perhaps think about it like boxing. You can practice drills and work on punch bags all you want, but at some point you need to get into the ring and do some actual sparring if you ever want to be ready to fight.

Practicing with an ex consultant is essentialy a simulation of a case interview. Of course, it isn’t possible to secure the time of experienced top-tier consultants for free. However, when considering whether you should invest to boost your chances of success, it is worth considering the difference in your salary over even just a few years between getting into a top-tier firm versus a second-tier one. In the light of thousands in increased annual earnings (easily accumulating into millions over multiple years), it becomes clear that getting expert interview help really is one of the best investments you can make in your own future.

Should you decide to make this step, MyConsultingCoach can help, offering bespoke mentoring programmes , where you are paired with a 5+ year experienced, ex-MBB mentor of your choosing, who will then oversee your whole case interview preparation from start to finish - giving you your best possible chance of landing a job!

7.3. Practice for online interviews

Standard preparation for interview case studies will carry directly over to online cases.

However, if you want to do some more specific prep, you can work through cases solo to a timer and using a calculator and/or Excel (online cases generally allow calculators and second computers to help you, whilst these are banned in live case interviews).

Older PST-style questions also make great prep, but a particularly good simulation is the self-assessment tests included in our Case Academy course . These multiple choice business questions conducted with a strict time limit are great preparation for the current crop of online cases.

7.4. Fit interviews

As we’ve noted, even something billed as a case interview is very likely to contain a fit interview as a subset.

We have an article on fit interviews and also include a full set of lessons on how to answer fit questions properly as a subset of our comprehensive Case Academy course .

Here though, the important thing to convey is that you take preparing for fit questions every bit as seriously as you do case prep.

Since they sound the same as you might encounter when interviewing for other industries, the temptation is to regard these as “just normal interview questions”.

However, consulting firms take your answers to these questions a good deal more seriously than elsewhere.

This isn’t just for fluffy “corporate culture” reasons. The long hours and close teamwork, as well as the client-facing nature of management consulting, mean that your personality and ability to get on with others is going to be a big part of making you a tolerable and effective co-worker.

If you know you’ll have to spend 14+ hour working days with someone you hire and that your annual bonus depends on them not alienating clients, you better believe you’ll pay attention to their character in interview.

There are also hard-nosed financial reasons for the likes of McKinsey, Bain and BCG to drill down so hard on your answers.

In particular, top consultancies have huge issues with staff retention. The average management consultant only stays with these firms for around two years before they have moved on to a new industry.

In some cases, consultants bail out because they can’t keep up with the arduous consulting lifestyle of long hours and endless travel. In many instances, though, departing consultants are lured away by exit opportunities - such as the well trodden paths towards internal strategy roles, private equity or becoming a start-up founder.

Indeed, many individuals will intentionally use a two year stint in consulting as something like an MBA they are getting paid for - giving them accelerated exposure to the business world and letting them pivot into something new.

Consulting firms want to get a decent return on investment for training new recruits. Thus, they want hires who not only intend to stick with consulting longer-term, but also have a temperament that makes this feasible and an overall career trajectory where it just makes sense for them to stay put.

This should hammer home the point that, if you want to get an offer, you need to be fully prepared to answer fit questions - and to do so excellently - any time you have a case interview.

8. Interview day - what to expect, with tips

Of course, all this theory is well and good, but a lot of readers might be concerned about what exactly to expect in real life . It’s perfectly reasonable to want to get as clear a picture as possible here - we all want to know what we are going up against when we face a new challenge!

Indeed, it is important to think about your interview in more holistic terms, rather than just focusing on small aspects of analysis. Getting everything exactly correct is less important than the overall approach you take to reasoning and how you communicate - and candidates often lose sight of this fact.

In this section, then, we’ll run through the case interview experience from start to finish, directing you to resources with more details where appropriate. As a supplement to this, the following video from Bain is excellent. It portrays an abridged version of a case interview, but is very useful as a guide to what to expect - not just from Bain, but from McKinsey, BCG and any other high-level consulting firm.

8.1. Getting started

Though you might be shown through to the office by a staff member, usually your interviewer will come and collect you from a waiting area. Either way, when you first encounter them, you should greet your interviewer with a warm smile and a handshake (unless they do not offer their hand). Be confident without verging into arrogance. You will be asked to take a seat in the interviewer’s office, where the case interview can then begin.

8.1.1. First impressions

In reality, your assessment begins before you even sit down at your interviewer’s desk. Whether at a conscious level or not, the impression you make within the first few seconds of meeting your interviewer is likely to significantly inform the final hiring decision (again, whether consciously or not).

Your presentation and how you hold yourself and behave are all important . If this seems strange, consider that, if hired, you will be personally responsible for many clients’ impressions of the firm. These things are part of the job! Much of material on the fit interview is useful here, whilst we also cover first impressions and presentation generally in our article on what to wear to interview .

As we have noted above, your interview might start with a fit segment - that is, with the interviewer asking questions about your experiences, your soft skills, and motivation to want to join consulting generally and that firm in particular. In short, the kinds of things a case study can’t tell them about you. We have a fit interview article and course to get you up to speed here.

8.1.2. Down to business

Following an initial conversation, your interviewer will introduce your case study , providing a prompt for the question you have to answer. You will have a pen and paper in front of you and should (neatly) note down the salient pieces of information (keep this up throughout the interview).

It is crucial here that you don’t delve into analysis or calculations straight away . Case prompts can be tricky and easy to misunderstand, especially when you are under pressure. Rather, ask any questions you need to fully understand the case question and then validate that understanding with the interviewer before you kick off any analysis. Better to eliminate mistakes now than experience that sinking feeling of realising you have gotten the whole thing wrong halfway through your case!

This process is covered in our article on identifying the problem and in greater detail in our Case Academy lesson on that subject.

8.1.3. Analysis

Once you understand the problem, you should take a few seconds to set your thoughts in order and draw up an initial structure for how you want to proceed. You might benefit from utilising one or more of our building blocks here to make a strong start. Present this to your interviewer and get their approval before you get into the nuts and bolts of analysis.

We cover the mechanics of how to structure your problem and lead the analysis in our articles here and here and more thoroughly in the MCC Case Academy . What it is important to convey here, though, is that your case interview is supposed to be a conversation rather than a written exam . Your interviewer takes a role closer to a co-worker than an invigilator and you should be conversing with them throughout.

Indeed, how you communicate with your interviewer and explain your rationale is a crucial element of how you will be assessed. Case questions in general, are not posed to see if you can produce the correct answer, but rather to see how you think . Your interviewer wants to see you approach the case in a structured, rational fashion. The only way they are going to know your thought processes, though, is if you tell them!

To demonstrate this point, here is another excellent video from Bain, where candidates are compared.

Note that multiple different answers to each question are considered acceptable and that Bain is primarily concerned with the thought processes of the candidate’s exhibit .

Another reason why communication is absolutely essential to case interview success is the simple reason that you will not have all the facts you need to complete your analysis at the outset. Rather, you will usually have to ask the interviewer for additional data throughout the case to allow you to proceed .

NB: Don't be let down by your math!

Your ability to quickly and accurately interpret these charts and other figures under pressure is one of the skills that is being assessed. You will also need to make any calculations with the same speed and accuracy (without a calculator!). As such, be sure that you are up to speed on your consulting math .

8.1.4. Recommendation

Finally, you will be asked to present a recommendation. This should be delivered in a brief, top-down "elevator pitch" format , as if you are speaking to a time-pressured CEO. Again here, how you communicate will be just as important as the details of what you say, and you should aim to speak clearly and with confidence.

For more detail on how to give the perfect recommendation, take a look at our articles on the Pyramid Principle and providing recommendations , as well the relevant lesson within MCC Academy .

8.1.5. Wrapping up

After your case is complete, there might be a few more fit questions - including a chance for you to ask some questions of the interviewer . This is your opportunity to make a good parting impression.

We deal with the details in our fit interview resources. However, it is always worth bearing in mind just how many candidates your interviewers are going to see giving similar answers to the same questions in the same office. A pretty obvious pre-requisite to being considered for a job is that your interviewer remembers you in the first place. Whilst you shouldn't do something stupid just to be noticed, asking interesting parting questions is a good way to be remembered.

Now, with the interview wrapped up, it’s time to shake hands, thank the interviewer for their time and leave the room .

You might have other case interviews or tests that day or you might be heading home. Either way, if know that you did all you could to prepare, you can leave content in the knowledge that you have the best possible chance of receiving an email with a job offer. This is our mission at MCC - to provide all the resources you need to realise your full potential and land your dream consulting job!

8.2. Remote and one-way interview tips

Zoom case interviews and “one-way” automated fit interviews are becoming more common as selection processes are increasingly remote, with these new formats being accompanied by their own unique challenges.

Obviously you won’t have to worry about lobbies and shaking hands for a video interview. However, a lot remains the same. You still need to do the same prep in terms of getting good at case cracking and expressing your fit answers. The specific considerations around remote case interviews are, in effect, around making sure you come across as effectively as you would in person.

8.2.1. Connection

It sounds trivial, but a successful video case interview of any kind presupposes a functioning computer with a stable and sufficient internet connection.

Absolutely don’t forget to have your laptop plugged in, as your battery will definitely let you down mid-interview. Similarly, make sure any housemates or family know not to use the microwave, vacuum cleaner or anything else that makes wifi cut out (or makes a lot of noise, obviously)

If you have to connect on a platform you don’t use much (for example, if it’s on Teams and you’re used to Zoom), make sure you have the up to date version of the app in advance, rather than having to wait for an obligatory download and end up late to join. Whilst you’re at it, make sure you’re familiar with the controls etc. At the risk of being made fun of, don’t be afraid to have a practice call with a friend.

8.2.2. Dress

You might get guidance on a slightly more relaxed dress code for a Zoom interview. However, if in doubt, dress as you would for the real thing (see our article here ).

Either way, always remember that presentation is part of what you are being assessed on - the firm needs to know you can be presentable for clients. Taking this stuff seriously also shows respect for your interviewer and their time in interviewing you.

8.2.3. Lighting

An aspect of presentation that you have to devote some thought to for a Zoom case interview is your lighting.

Hopefully, you long ago nailed a lighting set-up during the Covid lockdowns. However, make sure to check your lighting in advance with your webcam - bearing in mind what time if day your case interview actually is. If your case interview is late afternoon, don’t just check in the morning. Make sure you aren’t going to be blinded from light coming in a window behind your screen, or that you end up with the weird shadow stripes from blinds all over your face.

Natural light is always best, but if there won’t be much of that during your interview, you’ll likely want to experiment with moving some lamps around.

8.2.4. Clarity

The actual stories you tell in an automated “one-way” fit interview will be the same as for a live equivalent. If anything, things should be easier, as you can rattle off a practised monologue without an interviewer interrupting you to ask for clarifications.

You can probably also assume that the algorithm assessing your performance is sufficiently capable that it will be observing you at much the same level as a human interviewer. However, it is probably still worth speaking as clearly as possible with these kinds of interviews and paying extra attention to your lighting to ensure that your face is clearly visible.

No doubt the AIs scoring these interviews are improving all the time, but you still want to make their job as easy as possible. Just think about the same things as you would with a live Zoom case interview, but more so.

9. How we can help

There are lots of great free resources on this site to get you started with preparation, from all our articles on case solving and consulting skills to our free case library and peer practice meeting board .

To step your preparation up a notch, though, our Case Academy course will give you everything you need to know to solve the most complex of cases - whether those are in live case interviews, with chatbots, written tests or any other format.

Whatever kind of case you end up facing, nothing will bring up your skillset faster than the kind of acute, actionable feedback you can get from a mock case interview a real, MBB consultant. Whilst it's possible to get by without this kind of coaching, it does tend to be the biggest single difference maker for successful candidates.

Case Interview: The Free Preparation Guide (2024)

The case interview is a challenging interview format that simulates the job of a management consultant , testing candidates across a wide range of problem-solving dimensions.

McKinsey, BCG and Bain – along with other top consulting firms – use the case interview because it’s a statistically proven predictor of how well a candidate will perform in the role. The format is not only used by management consulting firms. Other types of organizations – like tech companies, financial services institutions, and non-profits – often use case interviews to assess candidates who are interviewing for roles focused on shaping strategic initiatives.

If you’re preparing to face a case interview, you may be feeling a little apprehensive. The format is notoriously demanding and unlike any other type of recruitment assessment you may have experienced before. However, with the right preparation and investment of time and effort, it is possible to master.

In this guide, we break down everything you need to know about the case interview, outlining exactly what you need to do to prepare effectively and ace the case.

Key takeaways

• The classic case interview format follows the same steps that a management consultant would encounter on a client project. The interview is a little like a role-play where the interviewer plays the role of a client and the candidate plays the part of the consultant hired to solve the problem.
• Some firms occasionally deviate from the classic case interview format. Popular alternatives include written case studies – which require candidates to review paper documents and then prepare and deliver a presentation – and market sizing case interviews, which require candidates to estimate a number.
• Case interviews test candidates against a set of six problem-solving dimensions: structuring, math, judgment and insights, creativity, synthesis, and case leadership. The interviewer uses a scorecard to assess the candidate’s performance in each of these areas.
• Case interview questions can be about almost any type of challenge or opportunity. However, our research indicates that there are 10 types of questions that are asked most frequently at top consulting firms. These include questions on profit improvement, revenue growth, and market entry.
• To do well in a case interview, it’s vital to create custom interview structures that meet the conditions of the ‘AIM’ test. It helps to have a good working knowledge of key case interview frameworks, but this alone is not sufficient.
• A strong grasp of case math is also crucial when it comes to case interview performance. While only high-school level math skills are required, it’s an aspect of the case interview that many candidates find challenging.
• Successful candidates are able to summarize their findings effectively. They also demonstrate strong case leadership by progressing through the case proactively and remaining focused on its overarching objectives.
• To prepare for a case interview, it’s essential to learn every problem-solving skill that will be assessed. We teach all of these skills in our Interview Prep Course , which contains all the video lectures, sample interviews, case material, and practice tools you’ll need to ace any case interview.
• Most candidates who go on to receive an offer from a top consulting firm like McKinsey, BCG or Bain complete at least 25 live practice sessions with a partner before their interview. You’ll find over 100 high-quality cases in our Case Library and a diverse community of candidates available for practice in our Practice Room .
• Some candidates choose to supplement their preparation by working with a coach who has been an interviewer at a top consulting firm. Here at CaseCoach, our coaches have all been handpicked from the alumni of top firms such as McKinsey, BCG and Bain.
• Although the world’s top consulting firms all test candidates using similar methods, none of them approach the interview process in exactly the same way. If you’re preparing to interview at a top consulting firm, it’s important to do your research and find out what you can expect.

An introduction to the case interview

The case interview format, the classic case interview.

The vast majority of case interviews follow the same steps that management consultants encounter on real client projects.

• Brief: The interviewer gives the candidate a brief for the case. They explain the context in which the client is operating, and outline the challenge they’re facing.
• Clarification: The candidate then has the chance to ask clarifying questions. They might do this to ensure they’ve understood the context of the problem correctly or to confirm the client’s goals.
• Reflection: The candidate takes 60 to 90 seconds or so to reflect and lay out a structured approach to solving the case.
• Analysis: The candidate and interviewer then work through the case together, carrying out analyses and moving toward a recommendation. This is the part of the case where you’ll be handling numerical questions, reviewing exhibits, coming up with creative ideas, and so on. It comprises the vast majority of the time you’ll spend on the case.
• Synthesis: The case concludes with the candidate synthesizing their findings and making an overall recommendation to the client.

So what does this unique interview format look and feel like? In reality, a consulting case interview is a little like a role-play. The interviewer plays the role of a manager or client, and the candidate plays the part of the consultant hired to solve the problem. However, a case interview shouldn’t feel like a performance. The most successful candidates treat it as a natural conversation between two professional people.

In the video below you can see an example of exceptional case interview performance in action. The candidate and interviewer in the video are both former McKinsey interviewers.

Interviewer-led vs candidate-led cases

Although the classic case interview has an established format and assesses a specific set of skills, cases can be delivered in different ways. Some are more candidate-led, while others are more interviewer-led

In a candidate-led case, the candidate is in the driver’s seat and is free to explore different aspects of the problem. Interviewers don’t tell candidates what to focus on next. Instead, they provide additional information – like an exhibit or a new fact – when asked. The candidate then analyzes the information and suggests next steps to get to the answer.

In an interviewer-led case, the interviewer may interrupt the candidate and ask them to either perform a specific investigation or focus on a different aspect of the problem. This doesn’t mean the interview is going badly; the interviewer is simply following a script. As a result, in an interviewer-led case, candidates are less likely to take the wrong path.

It’s difficult to predict which style of case you’ll receive. Some firms are known for using one style of interview more frequently than another. However, in practice, most interviews fall somewhere between the two extremes, depending on the style of the interviewer and the case material they’re using. You should therefore always be ready to suggest next steps and have a view about how to get to the answer.

Other case interview formats

While the classic case interview is most common, there are a couple of other interview formats that top consulting firms use from time to time:

The written case study

Some management consulting firms use written case studies to simulate the experience of carrying out consulting work even more accurately than the classic, verbal case interview. In some locations, BCG and Bain have been known to adopt this approach for a small minority of candidates.

In written cases, candidates review a series of paper documents and then structure the problem, run some numbers, generate ideas and, finally, deliver a short presentation. You can learn more in our article on how to crack written case studies .

Market sizing case interviews

Management consulting firms and other employers sometimes use market sizing questions – also known as estimation questions – as a standalone interview format to assess candidates on a wide range of problem-solving dimensions.

In a market sizing interview, you’ll be asked to estimate a number. This might be something like the revenue of a sandwich store or how many ATMs there are in a certain city. The ability to size a market is also a skill required for solving many case interview questions. You can learn more in our article on how to nail market sizing case interviews .

Some key differences to expect

While case interviews are highly codified, it’s important to remember that every interview is unique.

In the final round of interviews, for example, cases may feel less scripted than they did in the first stage. Partners – who are part of the interviewing group in the final round – often use the same case for years at a time. This means they can deliver it without a script and, as a result, tend to give candidates more room to take the lead. You can learn more in our article on the differences between a first and final-round interview at McKinsey, BCG and Bain .

In addition, each firm or office might bring their own nuance or style to the classic case interview format. It’s important to do your research and find out what you can expect from the interview experience at your target firm or office. You can learn more in our article on how the interviews at McKinsey, BCG and Bain differ .

The skills assessed in case interviews

Case interviews are primarily about testing a set of problem-solving skills. The interviewer uses a scorecard to assess a candidate’s performance in the following dimensions:

• Structuring: This is the ability to break problems down into logical drivers. It’s most obviously required at the beginning of a case, where you can pause and take a moment to come up with an approach. But it’s also tested each time you have to consider a new aspect of the problem.
• Math: Most cases contain a quantitative component, such as estimation questions, break-even questions, or other calculations. To do well in this dimension, you need to lay out a clear and efficient approach, run calculations quickly and accurately, and then state their implications for the case.
• Judgment and insights: This dimension is about extracting insights from data, usually by interpreting information in a chart. Performing well in this area involves processing new information quickly, prioritizing what’s important, and connecting your findings to develop sound recommendations.
• Creativity: Cases often have a creative thinking component. Sharing numerous, varied and sound ideas – ideally in a structured way – can help you succeed here.
• Synthesis: This is all about wrapping up the case with a clear and practical recommendation, and delivering it convincingly.
• Case leadership: This dimension is about progressing through the case efficiently and staying focused on its objectives. Case leadership involves gathering facts effectively and building on new findings to develop a recommendation. It’s a particularly important dimension in candidate-led cases.

Questions to expect

If you’re preparing to interview at a top management consulting firm like McKinsey, BCG or Bain, you’re probably curious about the kind of case interview questions you can expect to receive.

To identify the most common case interview questions , we surveyed CaseCoach users who interviewed at either McKinsey, BCG or Bain for a generalist role in 2023. We found that of the 260+ case interviews reported by respondents:

• 20% focused on profit improvement
• 15% focused on revenue growth
• 12% focused on market entry
• 10% focused on cost cutting
• 9% focused on process optimization

These topics align with the typical challenges and opportunities faced by CEOs. Because the job of a management consultant is to help CEOs find solutions to these problems, it’s vital for candidates to demonstrate that they understand the issues behind these questions.

However, while there are some recurring topics, the context and nuances of each individual case mean that no two case questions are the same. Increasingly, firms are testing candidates on questions that fall outside of these recurring topics. One way they’re doing this is by focusing on non-traditional areas, like the public sector. If you’re interviewing for a generalist management consulting role, it’s therefore important to be ready for almost any type of case question.

If you’re interviewing for a role that’s focused on a specific industry or function, like financial services , you’ll likely be given a case focused on that particular area.

How to ace the case

Case interviews require you to think on your feet to solve a complex problem that you’ve never seen before, while being assessed against a number of problem-solving dimensions. Here’s what you need to do to rise to the challenge and ace the case:

1. Create case interview structures that meet the AIM test

Of all the case interview assessment dimensions, structuring is perhaps the most challenging, particularly for those who are just starting out. It requires candidates to propose a prioritized and insightful approach to the case that’s composed of a comprehensive set of independent drivers. Structuring plays a foundational role in the interview, setting the course for the entire conversation.

So, what does good case structuring look like? An effective structure should meet the conditions of the ‘AIM’ test. ‘AIM’ stands for:

• Answer-focused: The structure should identify the client’s goal and the question to solve. It should also provide an approach to answering that question.
• Insightful: The structure should be tailored to the specifics of the client or to the problem in question. You shouldn’t be able to apply it to another case of the same type.
• MECE: This is a well-known acronym among consultants. It stands for ‘mutually exclusive and collectively exhaustive’. In plain English, if a structure is ‘MECE’ it has been broken down into an exhaustive set of independent drivers.

2. Know key case interview frameworks

In a case interview, you’ll be asked to structure a variety of problems. There are a number of frameworks that can help you do this, whether the problem you’re structuring corresponds to a common case question or a different topic entirely:

Business frameworks

You can use established business frameworks to craft custom structures for the most common types of case questions. These include frameworks for mastering profitability questions , answering revenue growth questions and nailing market sizing questions .

Academic frameworks

For unusual case questions that don’t relate to an obvious business framework, it can be helpful to draw on an academic framework like supply and demand, ‘the three Cs’, or Porter’s Five Forces. You can learn more about all of these in our ultimate guide to case interview frameworks . The article includes other business and academic frameworks that you can use to craft custom structures for case questions.

Logical frameworks

Finally, logical frameworks can help you look at the big picture in order to structure your approach. These options can be particularly useful when you’re faced with an unusual case question that doesn’t lend itself to a business or academic framework. Some examples of logical frameworks include:

• Structuring with equations: This approach is most helpful for quantitative case questions. Listen out for introductions that focus on a number. These cases can often be broken down into an equation and then structured along its variables.
• Structuring based on hypotheses: This approach is most helpful for structuring qualitative cases. It involves laying out what you most need to believe in order to validate a specific recommendation. These beliefs form your set of key hypotheses, which you then test as you progress through the case.
• Structuring with root causes: This approach works well for structuring cases that require identifying the reasons for a problem. It involves laying out its potential causes in a way that is mutually exclusive and collectively exhaustive (i.e. MECE).

How to apply these frameworks

While business, academic, and logical frameworks can be helpful when it comes to structuring a problem, learning how to use them correctly is a skill in itself. Simply applying a framework to a case interview question in a ‘cookie-cutter’ fashion is not enough. To impress your interviewer and pass the AIM test, your structure will need to be heavily tailored to the situation at hand. In fact, many case questions can be best answered by combining different frameworks.

Ultimately, interviewers want to understand how your mind works and see you think on your feet. You’ll therefore need to demonstrate that you can propose a custom case interview structure to any question.

3. Be comfortable with simple math

Management consulting firms expect you to navigate mathematical problems confidently and reliably in case interviews. Regardless of your academic background or past experience, you’ll need to be able to set an approach to solve the problem, perform calculations quickly and accurately, and state the implications of your solution.

The good news is that you’ll only be required to demonstrate a high-school level of math skills in case interviews. However, with no calculators allowed and an interviewer looking over your shoulder, it’s natural to find this aspect of the experience a little intimidating.

So, what can you expect from case math? The problems you’ll be asked to solve may take the form of straight calculations, exhibits that require calculations, word problems, and estimation questions.

To do well in this part of the case interview, you’ll need to have a strong understanding of:

• The four operations: addition, subtraction, multiplication, and division
• Key math concepts such as fractions, percentages, and weighted averages
• Business math concepts such as income statements, investments, and valuations

To stand out to your interviewer, you’ll also need to work through math problems confidently and efficiently. Here are our top tips for doing this:

• Keep track of zeros: Case questions often involve large numbers, sometimes in the millions or even billions. Keeping close track of your zeros is therefore crucial. We recommend either counting the zeros in your calculation, using scientific notation, or assigning letter units to zeros.
• Simplify your calculations: This will help you work through problems quickly and efficiently while reducing the potential for mistakes. One way of simplifying calculations is by rounding numbers up or down to make them more ‘friendly’.
• Memorize frequently-used fractions: Some fraction values are used so frequently in case math that knowing them – along with their percentage value and decimal conversions – can save you significant time. We recommend memorizing the fraction and corresponding percentage and decimal values of 1/2, 1/3, all the way through to 1/10.

You can learn more in our guide to mastering case interview math .

4. Summarize your findings

Synthesis is a key skill assessed by interviewers, predominantly at the end of a case interview. You need to provide a clear and sound recommendation that answers the overall question convincingly. You must also describe the key supporting points that informed your recommendation and then outline any further steps you would advise the client to take.

When it comes to concluding cases effectively, this four-step framework can be extremely helpful:

• Quickly play the case question back to your interviewer.
• Answer the question directly and briefly by distilling your response into a single sentence, if possible.
• List the points that support your conclusion.
• Outline the next steps that you recommend to the client.

You can learn more in our article on how to conclude a case study interview .

5. Bring it all together with strong case leadership

Case leadership, more than any other dimension, will give your interviewer an indication of how independently you could handle your workstream as a consultant. It’s a particularly important skill in candidate-led cases, where you’ll set the course of the discussion without the interviewer steering you in a particular direction.

Demonstrating strong case leadership means progressing the case efficiently and staying focused on its overarching objectives. Using a ‘tracker page’ to capture your structure and organize your notes throughout the case will help you in this regard.

Another aspect of case leadership is gathering facts effectively. This includes making reasonable assumptions, requesting missing information, and asking probing questions.

Finally, you’ll be expected to build on new findings to develop your recommendation, adapt your approach, and suggest next steps.

Effective case leadership is all about showing your interviewer that you have a strong command of the problem-solving process. After investigating each key driver in your structure, you need to be able to articulate where you are in your overall approach to solving the problem, and what the next steps should be.

To do this, we recommend using a five-step process to handle every kind of analysis you conduct during the case, whether you’re responding to a numerical question, the data in an exhibit, or something else.

Here’s what that five-step process looks like:

• Set your approach. Define what you’re going to do upfront. It’s particularly important to be explicit here, especially if the analysis is in any way complex or ambiguous.
• Conduct your analysis. Your approach here will vary according to the kind of question you’re working through.
• State your findings. You may also want to make a note of your findings on your tracker page.
• State the implications of your findings. Explain how they impact both your answer to the question and the client’s broader goal.
• Suggest next steps. Your findings will sometimes change how you want to approach the rest of the case. This may mean altering your initial structure and editing it on your tracker page.

6. Be your best on the day

When the day of your interview comes around, you’ll want to be at your very best. But what exactly does this mean?

First, you should present yourself in a professional manner. It goes without saying that you should arrive on time but, ideally, you should plan to arrive early. You should also come equipped with the right material: a pen, squared A4 or letter-size paper pad, and copies of your resume. It’s also vital to dress appropriately for the occasion. Usually, this means wearing formal business dress, but this means different attires in different locations. We recommend doing some research to find out what consultants wear at your target firm and office.

To be at your best on the day of your interview, you must be well rested. Sadly, tiredness is one of the most common reasons for underperformance in consulting interviews. The day before is not the time to cram in further preparation. Instead, aim to have a quiet day and to get plenty of sleep at night.

Ultimately, consulting firms want to hire people who can represent the firm and interact with clients at every level, from the shop floor to the C-suite. Successful candidates treat the case interview as an opportunity to play the role of a management consultant advising a client (i.e. the interviewer). This means exhibiting a great deal of confidence and credibility, together with effective communication and an engaging attitude. It’s vital to stay focused on the overall problem and to drive the resolution of the case while being receptive to the interviewer’s input.

There are a lot of balls to juggle in a case interview, with the added pressure of a potentially life-changing outcome, but successful candidates don’t let their nerves get the better of them. We’ve provided some helpful hints and tips in our article on handling the stress of consulting interviews .

Being your best on the day of your interview requires extensive preparation. It means mastering each dimension of the case interview scorecard to the extent that the skills become second nature to you. It also means completing sufficient case practice to be able to focus on the big picture of the case you’re solving, rather than on simply demonstrating a set of skills.

How to prepare for case interview success

Delivering a standard of performance worthy of an offer from a top firm requires extensive case interview prep. In our experience, most successful candidates invest around 60 hours – or 10 hours each week over a six-week period – in their preparation. Failing to put this effort in is among the most common reasons why many candidates are unsuccessful.

Here’s what effective case interview preparation involves:

Learning the skills

In a case interview, your performance is assessed against a set of common problem-solving dimensions. To recap, these are structuring, math, judgment and insights, creativity, synthesis, and case leadership. It’s important to:

• gain a precise understanding of the expectations on each of these skills
• learn the techniques that will allow you to meet these expectations
• practice until your performance meets the required standard

We teach all these skills in our Interview Prep Course . In our bite-sized video lectures, we map out each of the key skills assessed in a case, and explain what you need to know to demonstrate each skill. We also share our tips on how to improve in each dimension, going above and beyond the advice we’ve included in this article.

In addition, our Interview Prep Course includes many more sample interviews that show real candidates – who went on to join top consulting firms – solving cases. Former consulting interviewers explain what the candidates did well on each dimension and where they could have improved.

Math is a critical prerequisite to handling cases and is something you should be comfortable with before you begin practicing. Our Case Math Course – provided as part of the Interview Prep Course – will help you brush up your skills. It contains 21 video lectures that cover everything you need to know, including the four operations, key math concepts, our pro tips, and business math.

After watching all our Interview Prep and Case Math video lectures, we recommend heading to the ‘Drills’ area of CaseCoach, where you can start practicing specific skills. Drills are interactive exercises that pose rapid-fire questions and provide instant feedback. They help you build your skills and confidence in specific case dimensions quickly, allowing you to make the most of your live case practice with partners. Our Interview Prep Course includes a comprehensive set of drills in four key areas: structuring, calculation, case math and chart interpretation.

When it comes to succeeding in a case interview, nothing beats live practice with a partner. Most candidates who go on to receive an offer from a top consulting firm like McKinsey, BCG or Bain complete at least 25 live practice sessions before their interview.

To practice live cases with a partner, you’ll need access to both case material and practice partners. In our Case Library , you’ll find over 100 cases – complete with solutions – developed by former management consultants. You can download eight of these cases right away by creating a free CaseCoach account. You’ll find a diverse community of fellow candidates who are all available for case interview practice in our Practice Room , where we facilitate over 3,000 practice sessions a week.

You can learn more in our article on how to practice case interviews .

Working with a coach

Some candidates choose to supplement their preparations by working with a consulting interview coach who has been an interviewer at a top firm.

These coaches have the skills and experience to gauge your level of performance and help you identify your areas of strength and weakness. They can also provide you with accurate and helpful feedback on your case-solving skills. This insight can help you accelerate your preparation and improve your performance. Getting used to interviewing with a professional should also help to reduce the stress of the consulting interview experience.

Here at CaseCoach, our coaches are all former consultants and interviewers who have been handpicked from the alumni of top firms such as McKinsey, BCG and Bain.

Do your research

Although employers who use case interviews all test candidates using similar methods, none of them approach the interview process in exactly the same way.

For instance, if you expect to interview with McKinsey, Bain or BCG, it’s helpful to know that these firms all give cases of similar complexity. However, there are some key differences. For example:

• Bain has been known to use estimation questions, such as market sizing, in interviews for its most junior (i.e. Associate Consultant level) roles.
• BCG and Bain occasionally use written cases.
• When it comes to the ‘fit’ interview, McKinsey uses its Personal Experience Interview format, while most Bain offices now use a ‘behavioral interview’ . Only BCG consistently uses the classic fit interview format .

Other differences include the number of rounds of interviews each firm conducts, and their preference for using interviewer-led or candidate-led cases. Wherever you interview, it’s vital to do your research and find out what you might be able to expect.

When it comes to getting ready for the case interview, knowing what you will be assessed on, learning how to succeed, and having access to the best practice resources can all go a long way. Now, you need to put in the hard work and prepare! Good luck.

A case study interview isn’t your average interview. While most interviews ask you to give examples of how you use your skills on the job, in a case study interview, you’ll use those skills in front of the interviewer to solve a real-life problem.

It’s like auditioning for the school play. But instead of showing you can sing and dance, you’re using a case interview to show how you provide innovative solutions to pressing business problems. Not sure how to get ready for this kind of interview? We’ve got you covered. This guide explains how to prep for a case study interview.

Case studies are used across a variety of industries — everything from business to medicine. They are an in-depth examination, analysis, and critique of a real-world scenario the company experienced. People discuss the situation and explore what they learned while forming new solutions to try when they face a similar situation in the future and hope to improve their performance.

For example, doctors and nurses use case studies to improve how they diagnose and treat patients. Using real patient information, the medical team analyzes the case to see what the team may have missed and why they missed it. Learning from these errors helps the team better prepare for similar cases in the future to improve patient care.

While many industries use case studies to iterate and improve their performance, not every company uses case study interviews. This type of interview is very common at consulting companies (no matter what kind of consulting it is). But it’s not unusual for companies outside of consulting to use case interviews for marketing or operations roles.

In a case study interview, you’re given a real-world situation the company has faced and are tasked with analyzing it and suggesting a course of action.

Avg. Time: 5-6 hours

Skills you’ll build: Prioritizing, planning, data analysis, error spotting, communication, strategic thinking

Businesses use case study interviews to assess your abilities in real-time. While you’ll probably draw on a variety of skills, most case study interviews assess:

• Strategic thinking
• Analytical skills
• Common sense

The advantage of a case study interview is that the interviewer can evaluate your ability in each of these areas and see how you’ll actually use them on the job.

What Is a Fit Interview?

Some people use “case study interview” and “fit interview” interchangeably. While a fit interview and a case study interview both ask behavioral interview questions , they are not the same thing.

A case study interview assesses your ability to do the job. It primarily evaluates how you approach business problems and use your skills to solve them. A fit interview is about company culture fit. The interviewer asks questions that assess how well you’ll fit into the company, like asking you questions about what motivates you or how you lead .

Fit and case interviews are important parts of the evaluation process. Getting the job done is just as critical as getting along with coworkers and supporting the company’s mission. Depending on where you interview, you may have one fit interview and one case study interview, or the fit interview may be a smaller part of the case study interview.

What You’ll Learn in a Case Study Interview

A case study interview allows the hiring manager to see your skills in action and how you approach business challenges. But it also teaches you a lot about the company (even if you’re doing most of the talking).

In a sense, you’re behaving as an employee during a case study interview. This gives you a peek behind the curtain, allowing you to see the company’s inner workings, like how they approach business problems and what they expect from you and your performance.

For example, you may offer a novel approach to solving a problem during a case interview. How does the interviewer react to it? Are they impressed? Surprised? Is there a scowl or frown on their face? Their reaction gives you insights into how the company will likely receive your solutions.

Skills you’ll build: Critical thinking, creativity, brainstorming

Depending on the specific company, you may have the case study interview questions in advance, but you may not. Whether you do or don’t, here’s how to prepare for a case study interview.

Conduct Deep Research

Good interview prep for any interview means researching the company. That includes things like learning more about the company’s mission and the challenges the industry faces. But when you’re preparing for a case study interview, your research needs to go deeper. 

When you answer a case study question, your answer has to be specific to the company’s clients or business objectives. For example, if you’re interviewing for a role in strategy consulting , your answer shouldn’t focus on aspects of human resources consulting (unless it’s particularly relevant).

Your research needs to include the kinds of clients the company works with and what types of problems the company solves. For example, the company may only consult for Fortune 100 companies that need accounting advice. Keep these facts in mind as you prepare for the interview.

Case Study Interview Formats

There are four types of case study interview formats:

• Candidate-led: The interviewer asks you a specific question (or gives you a prompt), and you walk the interviewer through a detailed answer.
• Employer-led: The interviewer leads you through a series of specific (and predetermined) prompts and questions, no matter your answers.
• Presentation: You’re given a problem in advance to create and present a detailed case study.
• Video: Similar to a presentation case study interview, you’ll create a video presentation of the case study.

Most companies will tell you in advance which style of case study interview you should prepare for. But if they don’t, reach out to your recruiter or check the company’s website. Many include the essential details you need to prepare for the case study interview.

Seek Out Company-Specific Tips

Speaking of companies and their websites, not only do many companies that use case study interviews tell you the format, they often include helpful tips and tricks to help candidates prepare. This includes what to expect, what the company is looking for skill-wise, and what kinds of responses they want. They may even have a few practice questions and videos you can use to help you prep.

Unlike other common interview questions , it’s not as easy to prepare an answer to case study interview questions. Even though you know it’s a case study interview, you don’t necessarily know the specifics of the case or what problems you’ll be asked to solve.

Cybersecurity

Work through a case experience in this free course from PwC Switzerland. Create a pitch, conduct a risk assessment, and explain your findings.

Skills you’ll build: Risk management frameworks, cause analysis, risk impact assessment, system security

That said, it’s likely your case study interview questions will cover one or several of these concepts:

• Entering new markets
• Increasing profits
• Cutting costs
• Turnarounds
• Mergers and acquisitions
• Pricing strategy
• Developing new products
• Industry analysis
• Competitive response

While there are many ways to answer case study interview questions, a few basic prep tips can help you get ready for every question.

In addition to what you usually bring to a job interview , make sure you bring a notepad and pen or pencil to a case study interview. Taking notes will help you better understand the questions and formulate your answers. It also gives you a place to calculate numbers and figures if you need to. Not every case study interview allows calculators, so you’ll need to be ready to do your calculations manually.

Ask Specific Questions

As you’re working through the case study, you can and should ask any clarifying questions you need. The interviewer wants to hear specific, detailed answers that solve the problem. So, whenever you’re unclear, ask a follow-up question to not only get what you need but to give the interviewer what they need. 

That said, your question(s) should be very specific. You need to verify exactly what the interview is asking so you can create an appropriate answer. Say the interviewer gives you a broad question: The client’s revenue is falling. How do you help them increase it? You can follow up with a very specific question or two to make sure you understand what the interviewer is asking:

You’re asking how I would help the client raise revenue, correct? Are you also asking how I would help them increase their profit and cut costs?

Talk Them Through It

A big part of the case study interview is seeing you in action. However, in this case, “see” really means “how you think.” Since the interviewer can’t hear your inner monologue, you’ll need to practice thinking out loud.

While the interviewer wants to hear your solution, they also want to hear how you got there. That means talking through your entire thought process. Instead of saying, “I’d do X,” you have to explain how you arrived at your decision while you’re getting there.

Because not everyone thinks out loud, it may feel unnatural to you, and you likely won’t be expected to do it on the job. But it’s crucial to practice this skill — and it is a skill — because the interviewer is expecting you to do it in a case study interview.

Crafting Cases

Case Interview Examples: The 9 Best in 2024 (McKinsey, Bain, BCG, etc.)

February 7, 2024 By Julio Tarraf

Today I’m gonna show you a curated list of the 9 VERY BEST Case Interview Example videos from all around the web.

So you don’t have to go through the same pains I did back when I was preparing:

• I watched TONS of videos on YouTube, but most of my time was WASTED because many weren’t helpful at all.
• I couldn’t tell which cases were realistic and which were unrealistic, or which were hard and which were easy.
• I couldn’t even tell whether each answer by the candidates was good enough to pass the interview or not (my best proxy was their confidence, which I later found was NOT a good proxy).

So that brings us to this article.

What's in for you:

Every hour you spend on the examples in this article is the equivalent of spending 3-5 hours browsing YouTube on your own, reading Case in Point, or going through piles of casebooks.

This article is the result of...

24 of those videos didn’t make it to the list: they were  a mix of poorly recorded, unrealistic and even   misleading .

I curated just the best so you wouldn’t have to waste your own 20+ hours to find them.

Table of contents:

• #1. Playworks market entry  [Best for beginners]
• #2. Agricultural chemicals product launch [Advanced candidates only]
• #3. A+ Airlines’ reaction to competitor’s change
• #4. Auto manufacturer profitability decrease  [Best profitability case]

#5. Swift fox population decrease

• #6. Bed and Bath e-commerce acquisition  [Best for solo practice]

#7. FlashFash acquires LaMode

#8. medical supplies manufacturer demand decrease.

• #9. Pepsi’s LA bottling plant

CANDIDATE’S PERFORMANCE

• Stellar framework, touching on all relevant issues and showing a plan to solve the problem from beginning to end
• Great job performing a spontaneous reality check to his estimation
• I would expect more reasoning behind some of the key assumptions (# of high schools and colleges in the US). He was, however, close to the real values – his background as a teacher could have played a role, but as an interviewer I would still have needed to see his reasoning behind those numbers
• Big mistake inadvertently converting square yards to square feet (~10x difference in final answer) combined with math confusion within the Estimation and inefficiencies in Analysis: his analytical skills would have to be tested more thoroughly in a third interview or in a next round

The next case is mostly useful for its framework question.

It’s a high-quality, nuanced case question, similar to the ones you’ll get in McKinsey, Bain and BCG interviews.

The problem with this case is…

It requires either a well-structured answer or a ton of business sense, and the candidate solving it had neither.

As a result, he missed so many great insights, which made the video poor where it could have been rich for those who are practicing: business insight.

To spice up your practice, I’ll list those insights after the video under a spoiler alert, so you can add them to your own business sense library.

Given all of this, I would recommend this video for advanced candidates only .

(To understand what elements a perfect answer would need and how to create one for any case, check out our free course, Case Interview Fundamentals.)

#2. Agricultural chemicals product launch

Product launch

Candidate-led

• Tough case. Full of nuance, and suitable for an MBB first-round (perhaps even for a final-round).
• The analysis at  26:15  is a tough one, great practice for advanced students looking to improve their quantitative skills. Don’t forget that  you need to provide an insight after getting to the numerical answer.
• Right from the start, you can see that you’d need to (1) size the financial benefits orchards would get from using your product and (2) run viability and pricing analyses. The candidate fails to see this until the interviewer suggests it.
• The candidate missed several other important insights which would have been impressive. Can you spot any? Read them below, under the spoiler alert.

As I said, I’ll quickly go over the insights this candidate missed, as I think they could greatly add to your business sense library.

1) The one and most important is the pricing and viability analysis.

• One of the first questions that need to be answered when solving this case is, “what’s the size of the financial benefits of this product to the buyer, how much can we capture of it, and does it covers the manufacturing and distribution costs?”.
• The reason is simple: this analysis can be run entirely on data we most likely have (from research while developing the product), and it will quickly tell us if the product isn’t viable or if we need a strategy pivot.
• When guided, the candidate eventually runs this analysis, but the fact that this isn’t even explicit in his initial structure is still a red flag.
• Here’s what I would expect from a top-2% candidate. This analysis should have been outlined in the initial structure, along with a quick brainstorming of how this product might bring increased profits for the buyer.

2) There are several other potential sources of increased ROI that the launch of this product could yield that he didn’t even consider:

• Cross-selling opportunities to these same clients, once we’re selling Mango Maker to them.
• The possibility of selling this product in several other countries (thus potentially decreasing the costs of production with scale gains.)
• The possibility of selling this product to producers of other tropical fruits (to his credit, he did mention this when pressed, by the end of the video).
• The possibility of acting towards increasing the patent duration.
• The possibility of having some cash flow from the product after the patent expires.

The key to getting to those insights would have been to build a more robust initial framework. More business sense would help for sure, but  structuring techniques  are more feasible to practice and develop.

Lastly: the interviewer says, by the end of the video, that the interviewer would pass his first-round MBB interview with this performance. I do not agree with her.

While it is possible that his interviewers would pass him and let partners decide whether or not he’s suitable for the firm, the risk is just too high.

Some interviewers might pass him, but many others definitely would not.

Yale SOM Consulting Club and Elaine Dang deserve congratulations on the two videos they made.

It’s super high quality work. 

Both of their video examples are similar to real case interviews in format and content, and they’re even superior to some made by case interview prep websites.

#3. A+ Airlines' reaction to competitor's change

• Questions and difficulty realistic for McKinsey, Bain, or BCG
• A real case might have more Brainstorming questions within the case
• Negative: you can’t se the exhibits the candidate is shown
• Great: all of her answers were backed by at least one layer of structure
• Insights provided after calculating every new number, which is super important  (learn more)
• She did a good job keeping the interviewer on board by doing her math out loud at all times
• One thing she could’ve done better was to not constantly come back to the “cash tied up in the cash box” idea – she should’ve tested it once and definitively as to whether that is relevant or not (it isn’t) – a partner would have certainly challenged her on that

Featuring next: me reviewing my own video from a neutral point of view.

Yes, I know that can’t possibly be unbiased.

But here’s why I think this video will get you ahead of other candidates and why you should ABSOLUTELY NOT miss out on this :

• The case comes nearly straight from my own Bain final round.
• My question in the end is difficult (even for McKinsey, Bain or BCG’s standards), and Bruno’s answer is impressive.
• Bruno’s solution is not perfect, and this gives us both an opportunity to openly discuss how it could’ve been better by the end.

#4. Auto manufacturer profitability decrease

• Average-difficulty profitability case in the first half, and a difficult question at 15:44
• Full realistic drill-down to find the real root cause of the problem, which is a common thing in case interviews that you’ll only find in this video
• Bruno should have presented his answer as a plan before diving into the profit tree , which is an advanced skill that makes you sound more like a consultant and less like a candidate
• Efficient and organized drill-down in the profit tree, a must-master habit for all candidates
• Super insightful answer to the second question because it shows second-order level thinking

If you’re mainly looking to improve your performance in profitability cases, there are two pieces of content worth checking out:

• This video: 5 Tactics To Stand Out In Your Profitability Case Interviews
• And this article, the state-of-the-art in profitability trees: Profitability Trees: The Complete Guide

What I love about the next case is that the first question is on diagnosing a client’s issue, but it’s not a profitability case.

It’s actually a public sector case!

Most beginners think you only use issue trees and drill-down analysis when solving a profit problem, but as you’ll see in this case, this is not true at all.

The candidate’s answer is good, so you can compare your own answer to his.

• This is a difficult, realistic diagnostics case, great for advanced candidates to step up their practice with hard cases
• You are not shown a critical exhibit the candidate gets in the middle of the case, making it unsuitable for practice from then on
• The candidate’s initial structure is insightful because it breaks down the population problem into its key drivers
• The insights the candidate provided on the exhibits are spot-on, but I would expect next-steps after the conclusions (e.g. after 10:33 , he could have said  “And to figure out whether this really is the cause of the population decrease, the next thing I would do is…” )
• But he doesn’t make the same mistake twice – at 23:20 , he gets to a number the interviewer asked and, this time, he leads the case perfectly: he comes up with a conclusion (the insight), and then proactively leads the case with next steps

The next video is THE SINGLE BEST in this list for solo practice.

You will see Bruno’s reaction to challenges most people only face in their actual interviews. Mock interviews hardly prepare you for this at all:

• How should you react when an interviewer asks you for more ideas after you’ve given everything you have?
• What do you do when your interviewer asks for a recommendation having given you nearly no data?

Go ahead and see for yourself.

(And how would a real candidate do in this case? I interviewed a candidate with this very same case and recorded it so you could see for yourself. )

#6. Bed and Bath e-commerce acquisition

• Pay special attention to how I made spontaneous challenges to Bruno after his answers. Most mock interviews, even with consultants, don’t have that. So candidates end up getting surprised by them in their actual interviews. You might even want to show this to your peers so they’ll do more realistic mock interviews with you
• In 9:00 I challenge Bruno to see if he’s sure whether customer loyalty was good (higher customer lifetime value) or bad (harder to increase market share) for the acquisition
• In 16:22 I challenge Bruno to find even more ideas other than the ones he had already given
• Due to being interviewer-led AND having great benchmark answers, this is the best video in this list for solo practice
• Super structured brainstorming, which showed me he would not leave any important area behind and helped him give me a ton of creative, insightful ideas
• Insightful framework answer (e.g., 99% of candidates would not talk about whether running this business would be attractive to the friend, much less in depth like he did)

The next case is one of the unmissable videos in this list for two main reasons.

Number one, the candidate’s answers are great, good enough to be benchmarks to your own.

Number two, it’s a difficult M&A case (which is not as exciting as watching the last Avengers movie, I get, but still…).

• Realistic, challenging interviewer-led case for McKinsey, Bain and even BCG (as some interviewers there have been doing this type of case recently)
• Quality answers make it great for solo practice
• Insightful, well-built framework, definitely a benchmark
• Notice how the candidate shows his structure for the quantitative analysis before diving into the math – that’s a great habit you definitely want to copy

I chose this next video mostly due to the quality of the initial case question. Here’s why.

Most profitability cases in casebooks are simple: “industry Y, profits fell. Why?”

But the truth is, in real MBB interviews, the case question almost always has more nuance than that.

That’s what this next video’s initial case question shows.

Just a quick heads up: I would not pass this candidate, as I wasn’t a fan of his initial structure nor of his business sense in general. Your initial structure should be more robust than his.

Profitability

Below average

• The nuances of the case question make it a realistic one for MBB first-round interviews.
• This case could be way more interesting and insightful if the candidate had followed a different path, like finding different sources of revenue, different segments they could cater to at a higher price point, or new markets they could enter with the resources they have.
• Your answers to the initial case question and to all the other brainstormings in the case could (and should, if you’re aiming for the moon) be 5X more robust than this candidate’s. Don’t base your answers off his.  (Learn how to create robust brainstorming structures here.)  
• The analysis he performs is good, structure and communication-wise.
• Great insight that buyers’ price sensitivity would be driven by the switching costs if there were any ( 19:30 ) 

The next video shows an operations case example.

It’s a wonderful use of process structures to diagnose an issue on production line.

I don’t really like its style for practicing for two main reasons.

First, it just doesn’t have the right tempo for you to pause and practice and then compare answers. 

Second, the comments in the middle break the flow.

Nothing wrong with those comments. They’re actually helpful.

The problem is they make this video good for learning a few new concepts, watching a good structure put to use, but not really to practice by yourself.

If you’re an advanced candidate and your practice is up to date and you’re  just looking to learn something new, jump right in.

#9. Pepsi's LA bottling plant

• Only one person playing the interviewer’s and the candidate’s roles, which doesn’t give you an idea of how the case would flow
• Difficult case, great case for advanced candidates to increase their experience/library
• Not really tailored for you to pause and solve at each moment, doesn’t have a good tempo for that
• “Candidate’s” structure at 5:34 is a great example of a process structure put to use in diagnostics cases
• Super insightful brainstorming at 14:50 , with at least one idea you most likely wouldn’t think of

Want to learn to solve cases like the best interviewees in these videos?

Here’s the deal: you can watch as many of these great videos as you want, but they will only help you up to a point.

They’ll help you understand what a case interview is like…

And if you try to answer the questions as you watch them, these videos will even help you get some practice…

But examples of case interviews will never teach you HOW to do cases well.

And if you want to be outstanding at solving cases so that firms like McKinsey, Bain, or BCG are begging you to accept their offers, we have something for you!

We’ve created a free course that will teach you EXACTLY HOW to answer the 6 (and only six!) types of questions you will find in ANY case interview.

(You can even go back to ALL the questions asked within the 9 examples of this article… You’ll see that each of them can be answered using one of the six techniques.)

Now, you might be asking yourself: is this even worth my time?

I get that! There’s so much content out there, and so little time to practice.

Well, here’s the kind of e-mail we get from candidates all the time… It speaks for itself:

Bonus video!

In the beginning of this article, I told you there’d be a video by the end that didn’t make it to the list.

It’s  not that good to make it to a “best of” list. 

Still, I want to add it as a bonus, as it will add value to you in its own way.

#10. 1930's gangster growth strategy

But first, a word of warning... .

This video has a comment that could be misleading. Do NOT watch it without reading the comments.

Sometimes the greatest lessons come from mistakes. This is one of those times.

There’s a comment in the video in which the interviewer suggests that a necessary step in every case is “getting to” a chart.

This gives candidates two false impressions:

False Impression #1) There is a chart in every case, and your goal as a candidate it to “get to it”.

False Impression #2) If your interviewer has given you all the charts they had, you’ve done a good job!

Your goal as a consultant is to find the relevant hypotheses to solve the problem in a structured way and to test them with data.

If you do that, you will have done a great job, and your interviewer may or may not have given you a chart along the way.

This is true for interviews and the consulting job alike!

• Interesting case, as it’s a growth strategy in an unusual “industry”
• It is one of the few cases available online that let you practice Chart Interpretation questions, a common type at McKinsey, Bain and BCG
• Unfortunately, it gives the impression that “getting to all the charts” is the overarching goal of solving a case
• In the first Chart Interpretation question, the candidate missed a critical insight: that they already have 100% market share in all markets.  While the interviewer downplays it , it was a big foul that would be hard to recover from in a real interview
• The candidate provided insight after reading each exhibit – good job. However, he’d never proactively give clear next steps, which is what a well-prepared candidate would do
• If you’re practicing by yourself, remember not to use this candidate’s answers as a quality benchmark

How to Present a Case Study: Examples and Best Practices

Marketers, consultants, salespeople, and all other types of business managers often use case study analysis to highlight a success story, showing how an exciting problem can be or was addressed. But how do you create a compelling case study and then turn it into a memorable presentation? Get a lowdown from this post! 

Table of Content s

Why Case Studies are a Popular Marketing Technique 

Popular case study format types, how to write a case study: a 4-step framework, how to do a case study presentation: 3 proven tips, how long should a case study be, final tip: use compelling presentation visuals, business case study examples, what is a case study .

Let’s start with this great case study definition by the University of South Caroline:

In the social sciences, the term case study refers to both a method of analysis and a specific research design for examining a problem, both of which can generalize findings across populations.

In simpler terms — a case study is investigative research into a problem aimed at presenting or highlighting solution(s) to the analyzed issues.

A standard business case study provides insights into:

• General business/market conditions 
• The main problem faced 
• Methods applied 
• The outcomes gained using a specific tool or approach

Case studies (also called case reports) are also used in clinical settings to analyze patient outcomes outside of the business realm. 

But this is a topic for another time. In this post, we’ll focus on teaching you how to write and present a case study, plus share several case study PowerPoint templates and design tips! 

Besides presenting a solution to an internal issue, case studies are often used as a content marketing technique . According to a 2020 Content Marketing Institute report, 69% of B2B marketers use case studies as part of their marketing mix.

A case study informs the reader about a possible solution and soft-sells the results, which can be achieved with your help (e.g., by using your software or by partnering with your specialist). 

For the above purpose, case studies work like a charm. Per the same report: 

• For 9% of marketers, case studies are also the best method for nurturing leads. 
• 23% admit that case studies are beneficial for improving conversions. 

Moreover, case studies also help improve your brand’s credibility, especially in the current fake news landscape and dubious claims made without proper credit. 

Ultimately, case studies naturally help build up more compelling, relatable stories and showcase your product benefits through the prism of extra social proof, courtesy of the case study subject. 

Most case studies come either as a slide deck or as a downloadable PDF document. 

Typically, you have several options to distribute your case study for maximum reach:

• Case study presentations — in-person, virtual, or pre-recorded, there are many times when a case study presentation comes in handy. For example, during client workshops, sales pitches, networking events, conferences, trade shows, etc. 
• Dedicated website page — highlighting case study examples on your website is a great way to convert middle-on-the-funnel prospects. Google’s Think With Google case study section is a great example of a web case study design done right.

• Blog case studies — data-driven storytelling is a staunch way to stand apart from your competition by providing unique insights, no other brand can tell. 
• Video case studies — video is a great medium for showcasing more complex business cases and celebrating customer success stories.

Once you decide on your case study format, the next step is collecting data and then translating it into a storyline. There are different case study methods and research approaches you can use to procure data. 

But let’s say you already have all your facts straight and need to organize them in a clean copy for your presentation deck. Here’s how you should do it. 

1. Identify the Problem 

Every compelling case study research starts with a problem statement definition. While in business settings, there’s no need to explain your methodology in-depth; you should still open your presentation with a quick problem recap slide.

Be sure to mention: 

• What’s the purpose of the case study? What will the audience learn? 
• Set the scene. Explain the before, aka the problems someone was facing. 
• Advertise the main issues and findings without highlighting specific details.

The above information should nicely fit in several paragraphs or 2-3 case study template slides

2. Explain the Solution 

The bulk of your case study copy and presentation slides should focus on the provided solution(s). This is the time to speak at length about how the subject went from before to the glorious after. 

Here are some writing prompts to help you articulate this better:

• State the subject’s main objective and goals. What outcomes were they after?
• Explain the main solution(s) provided. What was done? Why this, but not that? 
• Mention if they tried any alternatives. Why did those work? Why were you better?

This part may take the longest to write. Don’t rush it and reiterate several times. Sprinkle in some powerful words and catchphrases to make your copy more compelling.

3. Collect Testimonials 

Persuasive case studies feature the voice of customer (VoC) data — first-party testimonials and assessments of how well the solution works. These provide extra social proof and credibility to all the claims you are making. 

So plan and schedule interviews with your subjects to collect their input and testimonials. Also, design your case study interview questions in a way that lets you obtain quantifiable results.

4. Package The Information in a Slide Deck

Once you have a rough first draft, try different business case templates and designs to see how these help structure all the available information. 

As a rule of thumb, try to keep one big idea per slide. If you are talking about a solution, first present the general bullet points. Then give each solution a separate slide where you’ll provide more context and perhaps share some quantifiable results.

For example, if you look at case study presentation examples from AWS like this one about Stripe , you’ll notice that the slide deck has few texts and really focuses on the big picture, while the speaker provides extra context.

Your spoken presentation (and public speaking skills ) are equally if not more important than the case study copy and slide deck. To make a strong case study, follow these quick techniques. Alternatively, you can learn how to present a business case here.

Focus on Telling a Great Story

A case study is a story of overcoming a challenge, and achieving something grand. Your delivery should reflect that. Step away from the standard “features => benefits” sales formula. Instead, make your customer the hero of the study. Describe the road they went through and how you’ve helped them succeed. 

The premises of your story can be as simple as:

• Help with overcoming a hurdle
• Gaining major impact
• Reaching a new milestone
• Solving a persisting issue no one else code 

Based on the above, create a clear story arc. Show where your hero started. Then explain what type of journey they went through. Inject some emotions into the mix to make your narrative more relatable and memorable. 

Experiment with Copywriting Formulas 

Copywriting is the art and science of organizing words into compelling and persuasive combinations that help readers retain the right ideas. 

To ensure that the audience retains the right takeaways from your case study presentation, you can try using some of the classic copywriting formulas to structure your delivery. These include:

• AIDCA — short for A ttention, I nterest, D esire, C onviction, and A ction. First, grab the audience’s attention by addressing the major problem. Next, pique their interest with some teaser facts. Spark their desire by showing that you know the right way out. Then, show a conviction that you know how to solve the issue—finally, prompt follow-up action such as contacting you to learn more. 
• PADS — is short for Problem, Agitation, Discredit, or Solution. This is more of a sales approach to case study narration. Again, you start with a problem, agitate about its importance, discredit why other solutions won’t cut it, and then present your option. 
• 4Ps — short for P roblem, P romise, P roof, P roposal. This is a middle-ground option that prioritizes storytelling over hard pitches. Set the scene first with a problem. Then make a promise of how you can solve it. Show proof in the form of numbers, testimonials, and different scenarios. Round it up with a proposal for getting the same outcomes. 

Take an Emotion-Inducing Perspective

The key to building a strong rapport with an audience is showing that you are one of them and fully understand what they are going through. 

One of the ways to build this connection is by speaking from an emotion-inducing perspective. This is best illustrated with an example: 

• A business owner went to the bank
• A business owner came into a bank branch 

In the second case, the wording prompts listeners to paint a mental picture from the perspective of the bank employees — a role you’d like them to relate to. By placing your audience in the right visual perspective, you can make them more receptive to your pitches. 

One common question that arises when creating a case study is determining its length. The length of a case study can vary depending on the complexity of the problem and the level of detail you want to provide. Here are some general guidelines to help you decide how long your case study should be:

• Concise and Informative: A good case study should be concise and to the point. Avoid unnecessary fluff and filler content. Focus on providing valuable information and insights.
• Tailor to Your Audience: Consider your target audience when deciding the length. If you’re presenting to a technical audience, you might include more in-depth technical details. For a non-technical audience, keep it more high-level and accessible.
• Cover Key Points: Ensure that your case study covers the key points effectively. These include the problem statement, the solution, and the outcomes. Provide enough information for the reader to understand the context and the significance of your case.
• Visuals: Visual elements such as charts, graphs, images, and diagrams can help convey information more effectively. Use visuals to supplement your written content and make complex information easier to understand.
• Engagement: Keep your audience engaged. A case study that is too long may lose the reader’s interest. Make sure the content is engaging and holds the reader’s attention throughout.
• Consider the Format: Depending on the format you choose (e.g., written document, presentation, video), the ideal length may vary. For written case studies, aim for a length that can be easily read in one sitting.

In general, a written case study for business purposes often falls in the range of 1,000 to 2,000 words. However, this is not a strict rule, and the length can be shorter or longer based on the factors mentioned above.

Our brain is wired to process images much faster than text. So when you are presenting a case study, always look for an opportunity to tie in some illustrations such as: 

• A product demo/preview
• Processes chart 
• Call-out quotes or numbers
• Custom illustrations or graphics 
• Customer or team headshots 

Use icons to minimize the volume of text. Also, opt for readable fonts that can look good in a smaller size too.

To better understand how to create an effective business case study, let’s explore some examples of successful case studies:

Apple Inc.: Apple’s case study on the launch of the iPhone is a classic example. It covers the problem of a changing mobile phone market, the innovative solution (the iPhone), and the outstanding outcomes, such as market dominance and increased revenue.

Tesla, Inc.: Tesla’s case study on electric vehicles and sustainable transportation is another compelling example. It addresses the problem of environmental concerns and the need for sustainable transportation solutions. The case study highlights Tesla’s electric cars as the solution and showcases the positive impact on reducing carbon emissions.

Amazon.com: Amazon’s case study on customer-centricity is a great illustration of how the company transformed the e-commerce industry. It discusses the problem of customer dissatisfaction with traditional retail, Amazon’s customer-focused approach as the solution, and the remarkable outcomes in terms of customer loyalty and market growth.

Coca-Cola: Coca-Cola’s case study on brand evolution is a valuable example. It outlines the challenge of adapting to changing consumer preferences and demographics. The case study demonstrates how Coca-Cola continually reinvented its brand to stay relevant and succeed in the global market.

Airbnb: Airbnb’s case study on the sharing economy is an intriguing example. It addresses the problem of travelers seeking unique and affordable accommodations. The case study presents Airbnb’s platform as the solution and highlights its impact on the hospitality industry and the sharing economy.

These examples showcase the diversity of case studies in the business world and how they effectively communicate problems, solutions, and outcomes. When creating your own business case study, use these examples as inspiration and tailor your approach to your specific industry and target audience.

Finally, practice your case study presentation several times — solo and together with your team — to collect feedback and make last-minute refinements!

35 Case Interviews Examples from MBB / Big Four Firms

Studying case interview examples is one of the first steps in preparing for the  management consulting  recruitment process. If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.

A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our  Case Interview 101  guide, if you haven’t done so.

McKinsey case interview examples

Mckinsey practice cases.

• Diconsa Case
• Electro-Light Case
• GlobaPharm Case
• National Education Case

What should I know about McKinsey Case interviews?

At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.

How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!

For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

BCG & Bain case interview examples

Bcg practice cases.

• BCG – Written Case – Chateau Boomerang

Bain practice cases

• Bain – Coffee Shop Co.
• Bain – Fashion Co.
• Bain – Mock Interview – Associate Consultant
• Bain – Mock Interview – Consultant

What should I know about BCG & Bain case interviews?

Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.

The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.

Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

For a detailed guide on candidate-led cases, check out our article on BCG & Bain Case Interview .

Deloitte case interview examples

Deloitte practice cases.

Undergrad Cases

• Human Capital – Technology Institute
• Human Capital – Agency V
• Strategy – Federal Benefits Provider
• Strategy – Extreme Athletes
• Technology – Green Apron
• Technology – Big Bucks Bank
• Technology – Top Engine
• Technology – Finance Agency

Advanced Cases

• Human Capital – Civil Cargo Bureau
• Human Capital – Capital Airlines
• Strategy – Club Co
• Strategy – Health Agency
• Technology – Waste Management
• Technology – Bank of Zurich
• Technology – Galaxy Fitness

What should I know about Deloitte case interviews?

Case interviews at Deloitte also lean towards the candidate-led format like BCG and Bain.

The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.

Accenture case interview examples

Accenture divides its cases into three types with very cool-sounding names.

Sorted in descending order of popularity, they are:

These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.

These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.

These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.

Capital One case interview examples

Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.

Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.

Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!

Case interview example – Case video

The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.

To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .

This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.

In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.

Here are seven notable areas where the candidate (and you) can improve:

Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.

Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .

Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.

Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.

Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.

Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.

Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .

Nonetheless, there are three good points you can learn from the candidate:

The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.

The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.

The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.

These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.

Once you’ve mastered them, you can nail any case they throw at you!

For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.

Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.

There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.

The profitability case we are about to watch will show that. It’s a very unconventional

Profitability. It started out like a typical one but getting more and more tricky toward the end.

The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started! 

It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.

My pitch would sound like this:

“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.

So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.

Does that correctly and adequately summarize the case?”

Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”

You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.

Alright, let’s break down the perfect opening.

First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:

1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.

And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.

You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.

Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.

Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.

Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:

1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.

Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.

Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.

Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on. 

Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.

Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.

To show of this habit in a case interview is very good!

There are three things I would like you to pay attention to:

First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.

No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.

No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!

Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:

First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.

Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.

Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.

So, summarizing the above insights, my pitch would sound something like this:

“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”

And while saying this, you should literally draw an issue tree and point to each as you speak.

There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.

I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:

Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.

Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.

Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.

Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.

My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”

Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.

Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.

In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.

Before we show you how to present your case study, let's discuss what should go in a case study . A well-written case study design should include the following sections:

1. Executive Summary

This section provides a brief overview of the entire case study. Readers should be able to scan it and get the hang of everything you want to discuss.

2. Problem Statement

This section should detail the goals and purpose of your case study.

You should highlight the problem you've identified that your study is looking to solve or questions you intend to answer through your case study. What are the main issues that led to the case study and what will your audience learn?

3. Solution

This case study slide forms the core of your case study. Here you want to explain how you solved the problem.

Discuss how other clients found you, what solutions they chose, why they chose them and how you implemented them.

4. Execution

This section should detail the journey to helping the client achieve the results.

You want to touch on the planning, processes, risks, metrics, KPI and factors you need to get an even better result. Describe the issues you faced during execution and how you mitigated them.

Here, you need to explain the positive impact or benefits of your solution on the client's project or business.

It could be financial results, growth results, improvements, or increases in productivity. Be sure to provide clear evidence like images, videos, statistical data and numbers.

6. Conclusion

Share reviews, quotes, testimonials and recommendations from existing customers about your solution.

When including these elements of a case study presentation, remember to back them up with visuals that engage your audience through storytelling and real-life examples.

Here's an example of a case study we created for Lincoln Learning Solutions, an online K12 curriculum provider founded in 2005.

Problem: The company was forced to downsize and ended up without a professional graphics designer on its team. As a result, they struggled to create visually appealing graphics.

They use Visme to create various visual content, including educational infographics, presentations, newsletters, social media graphics and more.

Below are some helpful tips for designing and presenting your case study to clients, prospects, investors and key stakeholders.

1. Determine Your Goals

This is the first step to designing your case study. What are you looking to achieve, or what message do you want to convey in your case study?

We get it. Case studies are created to demonstrate the value of your solution to customers. However, we recommend aligning your objectives with the value (solution and results) you want your customers to see.

For example, depending on your client's pain points, your objective may be to show your solution helped other clients to:

• Increase productivity, revenue and profit
• Minimize employee turnover
• Gain a competitive advantage
• Drive sustainability or energy efficiency

2. Pick a Compelling Case Study

Once you have outlined what your case study is set to achieve, you need to pick a suitable case study.

We recommend having an arsenal of case studies at your disposal. This will give you the variety you need to whip out and present the best and most relevant case study for each prospect.

Stand-out case studies boost credibility and drive prospects' interest in your solution. For example, you should prioritize case studies featuring reputable brands.

Another top choice is case studies of clients who had complicated problems or clients who left your competitors to work with you. These case study examples typically provide a more compelling story and outcomes.

3. Use Templates

Case studies riddled with design and visual flaws can put off prospects. Using templates keeps your presentation structure organized and visually appealing. Beautiful case study templates like the ones above make your job much easier. It allows you to spend your time on content rather than aesthetics.

4. Use High-Quality Visual Aids

When preparing your presentation, use quality visual aids to break up the text and keep your audience engaged.

You don't want to bore your audience with large walls of irrelevant text and vague statements. Instead, use more numbers and visual aids like charts , graphs , images and videos to show compelling proof of success. They make your message clear and lend credence to your arguments.

Did you help your clients increase sales? If yes, show the percentage increase in numbers and charts or graphs to show a spike.

Notice how the case study template highlights compelling figures using graphs and charts.

5. Deliver a Flawless Presentation

You've already put in a lot of effort to create a solid professional case study. However, even the best-written case study will fail to deliver without a winning delivery.

So, how do you get your clients to buy into your case study during the critical presentation phase? How do you present your case study in a simple, clear and persuasive way?

Keep reading.

Tell an Emotional Story

When presenting case studies, deploy storytelling—it works.

Think of storytelling as a hook that draws your audience into your presentation. Your story could clearly describe the problem a similar client faced, the solution you implemented and what they're currently enjoying.

It's not enough to use facts and figures alone. Injecting an emotional appeal into your narrative will make your case study memorable and impactful.

One way to create a human connection is by painting a clear picture your audience can relate to. You want to visualize their journey to success based on your results with existing clients.

Focus on the Client

Remember that the case study is not about you or your salesperson. Companies that focus more on themselves often come off as self-centered.

You should research your prospects and focus on their needs and challenges. Not only will your presentation be relatable, but it will have an emotional appeal and motivate your clients to take action.

So dig deep to find out these things:

• Your client's concerns and pain points
• The goals and outcomes your clients are looking to achieve and
• The problems holding them back from achieving their goals

The more you can align your presentation with the client's needs and clearly articulate them, the faster you can secure their buy-in. Otherwise, your case study will sound like a thinly disguised sales pitch.

Connect and Engage Your Audience

Do you want to avoid situations where your audience zones off or nods off to sleep during your presentations?

Make your presentation a two-way dialogue. The more you can engage your audience, the more impactful your presentation will be.

Here are some effective ways to engage your audience.

• Grab your audience's attention with a strong presentation opening . You can introduce yourself, tell a joke and review the agenda.
• Ask thought-provoking questions or seek their opinions to understand what value means to them.
• Smile and make eye contact to build rapport with your audience.
• Weave relatable visual aids, colorful metaphors, or other multimedia into your presentations to make your point stand out.
• Keep the conversation going and avoid sounding like you're giving a lecture or reading off a script.

You can also use Visme's interactive presentation tool to wow your audience by zooming into a key point in your presentation.

Keep It Brief and Interesting

No matter how much time you're allotted, keep your presentation brief.

Why does it matter? Humans have short attention spans. So, to avoid losing audience attention, spend more time on slides that drive home your points.

In the middle of the presentation, you may be asked to dive deeper into a particular aspect or answer other questions.

Whatever happens, be prepared to answer questions in the middle of your presentations. You can create appendix slides to expand on some aspects of your case study.

So there you have it. We've discussed everything you need to know about creating and delivering a stunning case study presentation.

Case studies can be an effective sales and marketing tool for convincing and converting prospects into paying customers. However, to deliver a smashing presentation that wows your audience, we recommend using Visme's case study templates . You'll find templates for every niche and use case.

Visme offers a wide array of design assets, visual aids, images, videos and animations to make your presentation pop.

5 Tips for Preparing for PwC and Strategy & Interview

PwC employs over a quarter of a million people in 155 countries worldwide. Its operations are divided into two parts: Trust Solutions and Consulting Solutions. Trust Solutions focuses on its accounting and tax services. PwC Consulting Solutions help a broad spectrum of clients navigate complex business issues by leveraging PwC’s significant experience and range of capabilities.

Client case studies include:

• helping TransRe adopt an enterprise resource planning system to collect and manage data, offering insight and improved decision-making.
• supporting Chipotle to implement a loyalty program to improve customer relationships, build loyalty, and drive business growth.
• providing pro bono consulting to charity The Trevor Project to strengthen its technological capabilities and optimize its volunteer recruitment process.

How does PwC Consulting differ from Strategy&?

In 2014, PwC acquired Booz & Co., the commercial arm of consulting firm Booz Allen Hamilton, and renamed it Strategy&. While PwC Consulting focuses on typical management consulting cases and implementation projects, Strategy& specializes in strategy consulting.

Set up by PwC to attempt to compete with McKinsey, Bain, and BCG, Strategy& has over 3,000 consultants helping businesses shape their future strategies. Strategy& focuses on creating competitive advantage by “developing corporate and business unit strategies and building differentiating capabilities that outperform the competition.” ( Source: PwC )

Implementation of those strategies is handed over to PwC consulting teams. If you join PwC’s management consulting team you will, “help clients translate strategy into execution, closing the gap between ideas and outcomes, to transform the organization and achieve tangible business results.” (Source: PwC)

Like most other Big 4 firms (EY, Deloitte, and KPMG), the PwC recruitment process has multiple stages:

Stage 1: The PwC Application

For entry-level recruitment, the first stage of the PwC process is to submit an application form for the particular roles you’re interested in. You can search for your school’s application deadline on PwC’s interactive campus map. If you can’t find your school or have recently graduated, you should submit by their September deadline. You’ll be asked to pick your top 2 preferred office locations and you’ll need to submit a resume.

Stage 2: The PwC Online Test

A few hours after you’ve submitted your application, PwC will send you an assessment to complete via email. You have to complete the online test within 3 calendar days so it’s worth thinking about that when applying. The PwC online test is a series of games-based assessments to measure cognitive ability, behavioral preferences, and verbal and numerical reasoning.

Learn more by reading PwC Online Test .

Stage 3: The PwC Interview

If you successfully pass the online test, PwC will invite you to a series of interviews. These will include a case interview and behavioral interview and may include a group case and an individual presentation. The first of these interviews is sometimes conducted as a video interview where you’ll record your answers to a range of questions and case studies. Group interviews have traditionally been part of the recruiting process for sophomore consulting internship candidates and select other groups. It’s a good idea to clarify with your recruiting contact what types of interviews you’ll have.

In the past, the bulk of the remaining interviews, group, or individual activities took place during an assessment day. However, for 2021-22 recruitment, PwC US is moving to virtual interviewing. For Consulting Services, you’ll face two virtual, live interviews back-to-back. If you move forward in the process, there may be a final additional  interview.

The case interview process is similar for both PwC Consulting Services and Strategy&. The case interviews are both candidate-led, which means you’ll be responsible for deciding what analysis you want to do and what the approach should be.

The PwC case interviews for Consulting Services applicants typically focus on profit optimization, cost optimization, and market sizing. For example, a recent candidate was asked to “Run me through a market sizing estimate of the iPhone market in Asia.”

For a breakdown of precisely what each of these types is, read Case Interview Types: Master Common Ones Before Your Interview .

The PwC Strategy& case interview includes more strategy-focused cases (such as make-vs-buy decisions, new product introduction, M&A, etc.), but how you tackle a case interview is the same no matter which area you’re applying for.

Following this 4-step model gives you the best chance for success:

• Understand the question . Make sure you understand what it is you’re being asked to do. Repeat back to the interviewing team what exactly you think the task is so they can correct you if necessary.
• Create a structured approach to the problem . Analyze what data you’ve been given and identify areas where you need more information about the client’s problem. Use a business framework to explore the case further or, better yet, create one of your own that’s specific to the issues in your case.
• Ask relevant questions and analyze the problem . Begin to share the assumptions you’re making about the case and ask the interviewing team questions about areas where you’re uncertain or need more data to inform your judgments.
• Effectively communicate your recommendation . Walk the interviewing team through your recommendation(s), explaining how you used the data provided to back up your recommendations. Make sure you call out any assumptions made or any risks associated with the action you’re proposing.

The fit or behavioral interview is a way for interviewers to figure out how well candidates would work within the firm’s culture and how they’d be in front of clients. Interviewers want to feel that they could work well with you if you were part of their team and that you’d represent the firm effectively on client projects.

While the exact questions will differ between firms, here are ten common questions asked in behavioral interviews:

PwC's Core Values

PwC has 5 core values that define its culture and approach:     

• Act with integrity
• Make a difference
• Work together
• Reimagine the possible

It’s important to ensure that when answering interview questions, you keep these values in mind. For example, if the interviewer asks you to tell them more about yourself or what you do for fun, pick stories that show where you’ve made a difference, challenged the status quo, or tried something new.

If you’re interviewing for several different firms, it’s important to tailor your responses to each individual firm. Try not to rely on stock answers about why management consulting is the role for you. Many other candidates will also be waxing lyrical about working with the best people, on the most interesting projects, for the most exciting clients.

Try researching cases the firm has recently been involved in and explain why they’re interesting to you. Or look into work the firm does regarding corporate social responsibility and talk about how it aligns with your values.

The Best Answers to PwC Behavioral Interview Questions Are Stories

Frame your examples as stories. Stories engage interviewers even after a long day interviewing dozens of candidates. While you want to remain professional, it’s ok to talk with emotion as you share your stories. Interviewers want to see humans, not robots! One of PwC’s core values is ‘Care’ so interviewers want to know what’s important to you and more about the things that make you you.

Make sure you also reflect on your own learning from the examples you want to share in your interview. You’ll likely be asked about how you work in a team, how you handle conflict, and how you overcome failure. Using a model like the ASTAR(E) framework helps you remember to share the effect that going through that experience had on you and how it’s changed how you would approach things in the future.

For the Strategy& interview specifically, it’s worth noting that you may face more behavioral questions than you expect. PwC is keen to check that you’re not just using Strategy& as an MBB backup and wants to make sure you’re a great fit for the firm.

PwC has traditionally used a group case as part of its recruiting process during the assessment day for some applicants (most frequently, undergraduate sophomores applying for internships). A typical group case experience involves you working within a small group to solve a business case.

Interviewers assess both analytical and behavioral competencies as you work in your team to solve the case. This means you have 2 roles during a group case. First, you need to contribute to solving the case — providing analysis, making logical assumptions and judgments, and offering insight to shape the overall recommendation you present to the client.

Secondly, you need to showcase how well you can work within a team — offering an opinion, demonstrating active listening, summarizing and building on others’ points of view, and leading the team towards consensus.

Recent interviewees have not had a group case as part of their PwC interview process. This is likely due to Covid restrictions, so make sure you are ready for a group case in the event PwC reintroduces them. If you want more help on preparing for a group case interview, read This Is What You Need to Know to Pass Your Group Case Interview .

As part of the recruitment process, you may be asked to prepare an individual presentation. This comes in the form of a written case presentation. Unlike other firms, PwC releases the information you’ll need to prepare your recommendation 48 hours in advance of the interview.

Using the information provided, you’ll have to prepare a PowerPoint presentation showing your analysis of the data, explaining any assumptions you’ve made, and detailing your client recommendations.

On the day of the interview, you’ll spend 15–30 minutes presenting your findings and then 15–30 minutes taking questions on them from the interviewing team.

Bain and BCG commonly request a written case, so this may feel familiar if you’ve interviewed for them. For more information on preparing for a written case interview, check out Written Case Interviews – Everything You Need To Know .

5 Tips for Preparing for PwC and Strategy& Interviews

Now you’re clear on the different elements that make up the PwC interviews, here are our top 5 tips for acing them:

1. Research

Make sure you do your research before your PwC or Strategy& interview. Understand what it is about the firm that appeals to you, what type of case work they’re involved in, and how else they get involved in the community.

It can sometimes be helpful to figure out what a company isn’t as much as what it is. So compare PwC to other firms and note the differences and why PwC still appeals. Learn their core values and what a typical day would involve as an analyst, or the specific role you’re applying for.

Ensure you also know as much as possible about the format for the interview. Are you expected to complete several tasks or just one? How much time will you have? Will you have a single interviewer or multiple? Company websites often describe the people they’re looking for to join their team — those will be the attributes you’ll be assessed against, so make sure you’re clear on what they are.

2. Prepare and Practice

Once you’ve done all your research, start your preparation. Use case interview examples to practice your casing skills. The linked page includes several PwC case examples as well as ones from other consulting firms. Make sure you feel confident in your case interview math skills too.

For your behavioral interview, make sure you’ve prepared answers to typical questions such as “Tell me about yourself” and “How would you manage a challenging team member?” Make sure your answers follow the ASTAR(E) framework and that you’ve tailored them to show off how you meet the PwC core values. You can practice answering these questions with a friend or coach until you feel confident in your responses.

3. Follow a Structure

Consulting firms are looking for structured thinkers who can solve a wide variety of business problems. Show your structured problem-solving skills by creating a framework that identifies the key issues you want to address in the case and use this framework to keep your progress in the case on track. Building your answers around a framework can help ensure you cover all the important points succinctly and confidently.

4. Explain Your Approach and Any Assumptions

Remember your math teacher always used to tell you to show your work? Well, it’s the same during consulting interviews. If you’re using data or solving math problems during your PwC case interview and you end up with an incorrect answer, it’s important to gain as much credit as possible.

Maybe you just made a small error in your calculation but your assumptions and approach were sound. The interviewer will never know that unless you walk them through the steps you take as you’re solving the case. Make sure you talk aloud as you’re putting together the pieces of the case and ensure you clearly state any assumptions you’ve made as you present your final recommendation. By making your assumptions clear, you‘ll allow your interviewer to guide you if you get off-track.

5. Communicate Confidently

In the PwC case interview, once you’ve decided on a recommendation, make sure you communicate your thoughts confidently. While interviewers are obviously interested in your analytical skills, business acumen, and logical approach, they also care about how you’re going to appear in front of clients. They need you to be able to effectively communicate your thoughts and respond appropriately to questions and feedback.

This is also true of the behavioral interview, where your interviewers also care about how you’ll fit within their team and what it’d be like to work long hours on a project with you. They’ll expect you to talk with passion about things you care about, offer thoughtful or interesting stories in response to questions, and seem friendly, competent, and approachable.

A Case Presentation of Pemphigus Vulgaris

Pemphigus vulgaris is a rare autoimmune disorder affecting the cell to cell adhesion molecules of keratinocytes in the epidermis and mucosa resulting in the production of the classic blister formation. This disease classically presents with intraoral blisters that may rupture and leave painful erosions impairing nutritional intake of patients. We present a case of a male in his early 40s noted to be earlier than the typical age of onset of Pemphigus Vulgaris. The patient had an atypical presentation of his lesions initially starting on his scalp rather than the typical oral involvement with bullous lesions at onset. Our case highlights the increasing incidence of malnutrition in patients with this condition. Our patient was found to have vitamin D insufficiency noting the association of Pemphigus Vulgaris with hypovitaminosis D with the call to action to include vitamin D screening in suspected or confirmed cases of Pemphigus Vulgaris. After discovering this patient’s primary diagnosis with punch biopsies, he was immediately started on a treatment regimen including corticosteroids and Vitamin D supplementation. The objective of this case report is to highlight this patient’s early onset of this disease as well as his atypical presentation. Additionally, we want to emphasize the association between Pemphigus Vulgaris and hypovitaminosis D to decrease the risk of further complications such as osteoporosis or life threatening injuries.

1. Introduction

Pemphigus Vulgaris is the most prevalent subtype in a collection of rare, autoimmune diseases known as Pemphigus. The pathogenesis involves autoantibodies against two main desmosomal adhesion proteins, desmoglein (Dsg)1 and desmoglein (Dsg)3. The binding of these pathogenic autoantibodies to these intraepidermal adhesion proteins results in the separation of keratinocytes, known as acantholysis, leading to the characteristic painful, oral erosions, and flaccid blisters on skin 1 . It affects approximately 0.1-0.5 per 100,000 people each year and has about the same prevalence in males and females 2 . The mean age of onset for affected patients is around 45 to 65 years of age 1 . The initial clinical presentation involves intraoral blisters that rupture and leave painful erosions causing impaired nutritional intake in many cases. Patients also have a positive Nikolsky sign on examination which is the easy expansion of bullae when lateral traction is applied 2 . The diagnosis can be reached through direct immunofluorescence of a biopsy involving normal-appearing perilesional skin or mucosa 2 . Histology will show evidence of acantholysis due to autoantibodies binding Dsg1 and Dsg3. Additional workup may include indirect immunofluorescence and enzyme-linked immunosorbent assay (ELISA) to detect circulating autoantibodies 2 . Mortality for patients with Pemphigus Vulgaris has significantly reduced from 75% to around 5% following the emergence of corticosteroids and adjuvant immunosuppressant therapies 3 . As a complication of these treatments, infections such as pneumonia and sepsis, are the leading cause of death in this patient population 3 . We report a case of a male with newly diagnosed Pemphigus Vulgaris.

2. Case Presentation

A 42-year-old Hispanic male with no past medical history presented to the ED with painful lesions on his head, left wrist, axilla, groin, and mouth. Patient reported that the lesions on his head began about one year ago, and the other notable lesions began about six months ago. He traveled to his home country, Mexico, about a year ago, during the onset of symptoms. He reported having fever and chills when the head lesions first appeared a year ago. He admits to having pruritus noting that the lesions were all pruritic except for the lesions in his mouth. Patient reported that his mouth lesions were severely painful when attempting to eat solid or liquid foods. He denied having any dysphagia or globus sensation. He notes that his symptoms have been debilitating as he has not been working for several weeks. He works as a construction worker where he lays concrete at work. No surgical or family history. No tobacco, alcohol, or illicit drug use. No sexual activity for over a year. No recent HIV or STI testing. He mentioned taking a course of diflucan about two months prior to evaluation at our facility with no improvement in his symptoms.

Patient’s physical exam was notable for macerated and erythematous appearing buccal mucosa with lesions on the hard and soft palates along with chelation on his lips as seen in Figure 1 . No lymphadenopathy noted in his head and neck. He had several indurated papules with and without eschar, on his left wrist ( Figure 2 ), midline of his back, and flat erythematous lesions on his right axilla. He was found to have right greater than left axillary and inguinal lymphadenopathy. Dry, crusted, psoriatic appearing lesions were noted on his scalp. Dry skin and excoriations were noted on the right groin. No clubbing or pitting were noted on his nails.

Initial lab work included a CBC and BMP that were unremarkable. CT chest/abdomen/pelvis with contrast was negative for any acute process. No acute intrathoracic or intra-abdominal abnormality. No thoracic, abdominal, pelvic, or inguinal lymphadenopathy. CT neck with contrast showed mild diffuse enhancement of the surface of the tongue musculature likely reflecting stomatitis with no deeper extension or abscess seen. Bilateral upper neck reactive lymphadenopathy was noted on imaging.

Infectious disease team was consulted during the patient's hospitalization for further evaluation. CRP, ESR, ANCA screen, ANA, HIV, RPR, Anti Ro/La, Fungitell assay, Urine histoplasma, and Urine blastomyces all came back negative. Vitamin A, B3, C, D, E, and folate levels were within normal limits except for Vitamin D. Patient was started on 50 mcg daily for his Vitamin D insufficiency. He had punch biopsies done on his left wrist and right axilla lesions. Right axillary lesion was remarkable for suprabasilar vesicle formation with an associated mixed inflammatory cell infiltrate within the dermis. Left wrist lesion was remarkable for an extensive suprabasilar vesicle formation with acantholysis of keratinocytes and an associated mixed inflammatory cell infiltrate within the dermis. In summary, both lesions were remarkable for suprabasilar vesicular dermatitis, mixed cell with frequent eosinophils ( Figure 3 ). The histologic features were found to be consistent with pemphigus vulgaris. PAS stains were performed on both biopsy specimens to rule out the possibility of concomitant infection. These stains were negative for fungi. He was started on Philadelphia swish and spit, Prednisone, Protonix, and Bactrim during hospitalization.

The patient was having worsening difficulty eating solid food for six months secondary to pain from the oral lesions. He was found to have severe protein calorie malnutrition evidenced by less than 50% of his estimated energy intake for over a month and 17% weight loss in less than 6 months. Oral Intake was encouraged during hospitalization with foods of pureed consistency. Per registered dietitian recommendations, the patient was also started on protein shakes three times daily with consideration for alternative nutritional supplementation if he was unable to get adequate nutrition from oral intake. Patient was able to eat solid food towards the end of his hospital stay as he had not been able to do so for the last six months.

Prior to discharge, the patient reported having significant improvement in his pain and pruritus. He was given instructions to follow up with a primary care provider and dermatologist for further management. The patient was discharged with prescriptions for 70 mg Prednisone daily, 40 mg Protonix daily for GI prophylaxis, Bactrim for Pneumocystis jirovecii pneumonia prophylaxis, Philadelphia swish and spit for oral symptoms, and Vitamin D for his vitamin D insufficiency. Following discharge, the patient was followed by the dermatology team at our primary care clinic. He was found to have elevated desmoglein 1 antibody at 58 and elevated desmoglein 3 antibody at 160. He had positive circulating IgG anti-epithelial cell surface antibodies with a titer of 1:80. Patient is currently on Mycophenolate Mofetil (Cellcept) with the plan to transition him to Rituximab and taper prednisone.

3. Discussion

Pemphigus Vulgaris classically affects elderly individuals within the age of 45 to 65 years old 1 . Our patient presented at our facility for evaluation a year after onset of his symptoms at age 42. In about 80% of patients affected with Pemphigus Vulgaris, the first sign of the condition usually starts with oral involvement in the form of blisters that eventually rupture resulting in excruciating erosions StatPearls [Internet]." class="coltj"> 2 , Ethiopian journal of health sciences , 25 (4), 367–372." class="coltj"> 4 , The Journal of Emergency Medicine , 56 (1), 102–104." class="coltj"> 5 , Pan African Medical Journal, 42 (184)." class="coltj"> 6 . The typical pattern of Pemphigus Vulgaris is the development of cutaneous lesions after the development of oral blisters 2 . Our patient had a different presentation as his symptoms initially began on his scalp six months prior to the development of lesions in his oral mucosa, and cutaneous lesions to his left wrist, axilla, back, and groin.

The characteristic skin finding of this condition is noted to be a blister formation in the form of a “thin walled bulla” 4 . This is due to the fluid buildup from the destruction of the cell to cell adhesion of keratinocytes in the epidermis and mucosa Ethiopian journal of health sciences , 25 (4), 367–372." class="coltj"> 4 , Annual Review of Pathology: Mechanisms of Disease , 11 (1), 175–197." class="coltj"> 7 . This destruction is done by autoantibodies targeting desmoglein, a known cell adhesion molecule. Our patient did not present with the typical blister formation on his left wrist as evidenced in Figure 2 . During the patient interview on presentation, he denied having any known blisters prior to evaluation at our facility. However, the lesions found may represent the remains of bullous lesions that had ruptured.

Due to the excruciating pain of oral lesions in affected patients, there is usually a degree of malnutrition noted as patients have decreased oral intake 2 . Our patient was no different in this aspect as he had worsening oral intake since the presence of oral lesions six months prior to evaluation at our facility. He mentioned that he began having blended foods to get some nutrition in for the day. This was evidenced by his severe protein calorie malnutrition with less than 50% of his estimated energy intake for over a month and 17% weight loss in less than 6 months.

Our patient was found to have vitamin D deficiency with low vitamin D noted on workup. A meta-analysis done by Yang et al showed a remarkably lower vitamin D levels in patients with autoimmune bullous dermatoses such as Pemphigus Vulgaris than in the control population 8 . Affected patients with Pemphigus Vulgaris have an increased risk of hypovitaminosis D and vertebral fractures 9 . One of the mainstay treatments for pemphigus vulgaris is glucocorticoid therapy. Steroids are known to cause hypovitaminosis D and osteoporosis. The meta-analysis done by Yang et al noted that patients with no steroid treatment had vitamin D insufficiency as well suggesting that the hypovitaminosis D is not just an adverse effect of steroid therapy but a result of the condition 8 . Hypovitaminosis D puts affected patients at risk for osteopenia, osteoporosis, fractures from falls with debilitating injuries that can affect quality of life. This can be avoided if they are routinely monitored and repleted with supplementation. Future research work on Pemphigus Vulgaris should be targeted at pathophysiology behind pemphigus vulgaris and hypovitaminosis D.

4. Conclusion

Pemphigus Vulgaris is a rare autoimmune disease usually seen with equal prevalence between males and females. Our case involves a male who is younger than the mean age of affected patients with this condition. Initial imaging and lab work were helpful in ruling out potential diagnoses. Ultimately, the primary diagnosis was confirmed with the punch biopsies of lesions in the right axilla and left wrist. This resulted in starting the regimen of 70 mg Prednisone daily, 40 mg Protonix daily for GI prophylaxis, and Bactrim for Pneumocystis jirovecii pneumonia prophylaxis. Our patient had rapid improvement in symptoms and was able to eat solid food prior to discharge. The aim of this case report was to highlight this individual’s early presentation of Pemphigus Vulgaris based on his age at symptom onset, and his atypical presentation of initial lesions originating in the scalp prior to oral involvement. Additionally, we wanted to highlight the association of hypovitaminosis D and pemphigus vulgaris with a call to action on including vitamin D labs in suspected or confirmed cases. Future research work on Pemphigus Vulgaris should be targeted at pathophysiology behind pemphigus vulgaris and hypovitaminosis D.
