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.

Before diving deep into how to prepare for a Reddit product management case interview, it's essential to understand the role of a product manager in Reddit. At its core, the role of a product manager at Reddit is all about innovation. Product managers are responsible for identifying new opportunities to improve user experience, design, and functionality while also maintaining a clear product roadmap. They collaborate with cross-functional teams, including engineering, design, and marketing, to bring new products and features to life.

Additionally, product managers at Reddit are also responsible for analyzing user data and feedback to make informed decisions about product development. They work closely with the community team to understand user needs and preferences, and use this information to prioritize product features and improvements. Product managers also play a crucial role in ensuring that Reddit's products and features align with the company's overall mission and values, such as promoting open discussion and free speech.

What to Expect in a Reddit Product Management Case Interview

A Reddit product management case interview typically consists of several scenarios revolving around hypothetical product situations. You will be asked to discuss your decision-making process and the steps you would take to solve a particular problem. You will also be asked to answer behavioral questions that will test your strategic thinking, problem-solving skills, and your ability to work in a team.

One important aspect of a Reddit product management case interview is the emphasis on data analysis. You may be given a set of data and asked to analyze it to make informed decisions about a product. This requires a strong understanding of data analysis tools and techniques, as well as the ability to communicate your findings effectively.

Another key component of the interview is your ability to think creatively and outside the box. You may be presented with a problem that has no clear solution, and you will need to come up with innovative ideas to address it. This requires a combination of critical thinking skills and a willingness to take risks and try new approaches.

Common Reddit Product Management Case Interview Questions

Some of the common questions that you can expect in a Reddit product management case interview include:

• How would you approach the development of a new feature for Reddit?
• What is your process for discovering customer needs and pain points?
• How would you prioritize features for a product when faced with limited resources?
• How do you evaluate the success of a product feature?

Another common question that may come up in a Reddit product management case interview is:

• How do you balance the needs of different stakeholders, such as users, advertisers, and internal teams?

It's important to have a clear understanding of the priorities and goals of each stakeholder group, and to find ways to align their interests as much as possible. This may involve making trade-offs and compromises, and communicating effectively with all parties involved.

Additionally, you may be asked:

• How do you stay up-to-date with industry trends and emerging technologies?

As a product manager, it's crucial to be aware of the latest developments in your field, and to continuously learn and adapt. This may involve attending conferences, reading industry publications, and networking with other professionals in your field.

How to Research Reddit's Products and Services for the Interview

One of the best ways to prepare for a Reddit product management case interview is by researching the company's products and services. You can start by browsing through Reddit's various subreddits and understanding how users interact with the site. You can also read the company's blog posts and announcements to get a better understanding of their product roadmap and future plans. Make sure to take notes and jot down any questions you may have for the interviewer.

Another useful way to research Reddit's products and services is by analyzing their competitors. Look into other social media platforms and online communities to see how they differ from Reddit and what unique features Reddit offers. This will give you a better understanding of Reddit's market position and how they differentiate themselves from their competitors. Additionally, you can search for any recent news or controversies surrounding Reddit to gain insight into the company's current challenges and how they are addressing them.

Understanding Reddit's User Base and Community Culture

Reddit has one of the most active and passionate user bases on the internet. Understanding the community culture is vital to developing a successful product strategy. Spend time browsing through various subreddits that align with your interests and get a feel of the language used, what's popular, and what's not. This will help you better understand what resonates with users on the platform.

It's important to note that Reddit's user base is diverse and can vary greatly depending on the subreddit. Some subreddits may have a more niche audience, while others may have a wider appeal. Additionally, the community culture can also differ between subreddits. It's important to research and understand the specific subreddit you are targeting to ensure your product or message aligns with the community's values and interests.

Practicing the STAR Method for Answering Behavioral Questions

An effective way of answering behavioral questions in a Reddit product management case interview is by using the STAR method, which stands for Situation, Task, Action, and Result. Start by discussing the situation in detail, followed by the task at hand. Then explain your action plan and the result you achieved. Utilizing the STAR method ensures that you provide answers that are concise and structured, making it easier for the interviewer to follow and understand.

Another benefit of using the STAR method is that it helps you stay focused on the question being asked. By breaking down your answer into specific components, you can avoid going off on tangents or providing irrelevant information. This can also help you avoid rambling or getting lost in your own thoughts, which can be a common pitfall in interviews.

It's important to practice using the STAR method before your interview, so that you feel comfortable and confident when answering behavioral questions. You can do this by reviewing common behavioral questions and practicing your responses using the STAR method. You can also ask a friend or mentor to conduct a mock interview with you, so that you can get feedback on your answers and refine your approach.

Tips for Demonstrating Your Strategic Thinking Skills in the Interview

A crucial aspect of a Reddit product management case interview is demonstrating your strategic thinking skills. Product managers need to have a clear sense of direction and a vision for the product's future. One way to showcase your strategic thinking skills is by asking thought-provoking questions and demonstrating a deep understanding of the product and the user's needs. Make sure to have a clear rationale for your ideas and be prepared to defend them.

Preparing for Hypothetical Situations and Problem-Solving Exercises

Another critical aspect of a Reddit product management case interview is being prepared for hypothetical situations and problem-solving exercises. Readily identify the key issues and devise a step-by-step solution plan. Communicate your line of attack and ask clarifying questions to ensure that you understand the problem statement fully. Be prepared to pivot and adjust your approach based on feedback from the interviewer.

Utilizing Resources such as Mock Interviews and Sample Questions

An effective way to prepare for a Reddit product management case interview is by utilizing resources such as mock interviews and sample questions. Look for online resources that simulate a Reddit product management case interview and practice your answers out loud. Get feedback from friends, family, or colleagues who work in similar roles to get a sense of your strengths and areas for improvement.

Mindset and Attitude: How to Approach the Interview with Confidence

Approaching a Reddit product management case interview with confidence is just as essential as having a strong technical background. Keep a positive mindset, stay relaxed, and be receptive to feedback from the interviewer. Don't be afraid to ask questions and showcase your unique point of view. Remember that the interviewer is also evaluating you based on how you approach the problems presented and how you work within a team.

Following Up After the Reddit Product Management Case Interview

After the Reddit product management case interview, it's essential to follow up with a thank-you email to the interviewer. Restate your interest in the position and highlight what you liked about the interview process. Use this opportunity to address any questions or concerns that may have arisen during the interview. Your follow-up email should express gratitude for their time and consideration.

By following the tips outlined in this article, you'll be better prepared to tackle a Reddit product management case interview. Remember to stay calm, think through each question, and demonstrate a clear vision for the future of the product. Good luck!

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.

A Comprehensive Guide to Case Interview Prep [tips updated 2024]

• Last Updated June, 2024

Rebecca Smith-Allen

Former McKinsey Engagement Manager

What Are the Best Ways to Prepare for Management Consulting Interviews?

Congratulations!

If you’re on this page, you’re probably considering a career in management consulting or are already in the middle of the interview process.

We’re here to help.

We’re a team of more than 20 former McKinsey, Bain, and BCG consultants and recruiters (our average time in consulting is 13 years each) and we put together this guide to help you prepare for getting your consulting offer.

After reading this, we hope “congratulations” is also what you’ll hear when you leave your second round interviews.

Management Consulting Jobs Are in High Demand

Management consulting jobs are among the most sought-after positions in on-campus recruiting, whether you’re applying as an undergraduate or from a business school. 

Consulting firm recruits also include law school students, Ph.D. program candidates and people who’ve already started their professional careers in other industries.

Management consulting firms are filled with smart, driven people working to solve hard business problems. 

This work is a great launching pad for your career. 

Top consultancies offer competitive salaries and also invest significantly in employee development. A job at a management consulting firm will expose you to multiple different industries and types of business problems. 

There’s a lot to like about a career in consulting!

Competition for Jobs with Top Consulting Firms Is Fierce

But attractive jobs are usually highly competitive, and that’s definitely the case in management consulting. 

Top firms typically make offers to only about 1% of the people who apply. It’s not impossible to get a job with firms like McKinsey, Bain, and BCG (also known as the MBB firms), but it requires preparation.

In particular, successful candidates know that consulting firms use a particular type of interview question — the case study interview — and they know what recruiters are looking for in answers. 

In this article, we’ll help you prepare for management consulting interviews by answering the following questions:

• What is a case interview?
• How do I answer a case question?
• What is the best approach for case prep?

We’ll also provide tips and tricks that will help you to ace your case.  

Whether you’re aiming for a job at one of the MBB firms (McKinsey, Bain, or BCG), with other consultancies such as AT Kearney, L.E.K. or Oliver Wyman, or with the consulting arms of the large accounting firms such as Deloitte, Accenture, PwC, Ernst & Young, or KPMG, we can help you get there.  

What Is a Consulting Case Study Interview (also known as the “Case Interview”)?

A Case Study Interview is a real-time problem-solving test used to screen candidates for their ability to succeed in consulting. 

The case is presented as an open-ended question, often a problem that a specific type of business is facing, that an interviewer asks a candidate to solve.

Sample Case Interview Questions

Sales of drinks in Coffee Bean cafes are decreasing. What is causing the sales decrease?

Turnover of store employees at Burgers R’ Us restaurants has increased over prior years. What would you advise the company to do?

Donations to Caring Hands are decreasing, straining the non-profit’s ability to help the families it targets. What should the organization do to turn this around?

Case Interview 101 – The Basics for Beginners

You don’t need an MBA or an undergraduate degree in economics to land a job in consulting. But you will need to learn some business basics to be able to crack case interviews.

This section covers the concepts non-business students need to become familiar with, such as:

• The income statement – an overview
• Common formulas used in case interviews
• Business concepts you need to know
• Common types of case interviews

Case Interview 101, Part 1: The Income Statement

To solve cases, you first need to understand broadly how companies make money. For any specific case, you’ll want to make sure you understand how that company makes money. 

The most common way companies make money is by selling a product or service for more than it costs to produce, thereby earning a profit . 

Companies use three major financial statements to monitor and report their financial performance: 

(1) The income statement (2) The balance sheet (3) The cash flow statement 

An income statement (or profit and loss statement or statement of revenue and expenses) is a record of a company’s profit or loss over a specific period of time . The profit or loss is calculated by taking the revenues generated and subtracting the expenses incurred over the same period of time. The income statement has 3 major categories: Revenue, Expenses, and Profit or Loss .

Revenue is the total amount of money generated by a company from selling its products or services. It is also referred to as gross sales or “top line” as it sits at the top of the income statement. 

Costs are expenses incurred by a company to make its products or services. In the income statement there are three types of costs: 

• Costs of goods sold (COGS) or cost of sales are the direct costs of making products or providing a service. For a burger restaurant, for example, the COGS would include things like the meat, bun, and hourly labor of cooks, cashiers, and shift supervisors.
• Operating expenses are costs that are indirectly tied to the making of products or services. These include selling, general, and administrative (SGA) expenses, management salaries, depreciation, and amortization. Depreciation and amortization are non-cash expenses that reflect the value of big assets like machinery or buildings going down over time. For example, if our burger restaurant buys a grill to cook burgers on for $1,000 and expects it to last for 10 years, it would spread out the cost over that period, $100 per year. Other operating expenses for our burger restaurant would include things like advertising, the rent on the company’s headquarters, and the salary of the CEO.
• Costs incurred from non-operating activities such as interest paid on loans. These costs are rarely part of case interviews.

Profit or Loss :

Income statements generally show 3 levels of profit (loss) or earnings: Gross Profit; Earnings Before Interest, Tax, Depreciation and Amortization (EBITDA); and Net Profit.

Gross profit or loss

This is calculated by subtracting COGS or the cost of sales from the total revenue generated. If the costs are higher than the revenue generated, then the company has made a loss.

EBITDA and EBIT

EBITDA is calculated by subtracting operating expenses from the gross profit. EBIT is calculated by subtracting depreciation and amortization from EBITDA. 

As mentioned above, depreciation and amortization are non-cash expenses. So if the amount of cash generated by selling a product or service is important to your analysis, you should look at EBITDA. If looking at a more fully loaded cost is the focus of your analysis, use EBIT.

Net Profit or Loss

This is calculated by subtracting interest and tax from EBIT. It is also known as Net Income and refers to the profit (or loss) for the period. This is also known as the “bottom line” as it sits at the bottom of the income statement. This is the ultimate measure of whether a company’s activities are profitable during a certain time period when all costs are considered.  

Case Interview 101, Part 2: Common Formulas Used in Case Interviews

Here is a look at common formulas used in case interviews.

Profitability formula:

The profitability formula is used in profit (or loss) related cases. The profit or loss can be calculated using the following formula:

             Profit (or Loss) = Revenue – Costs

As mentioned above:

• Revenue is the money generated from selling a product or service. It can be broken down into price per unit and number of units sold . 
• Costs are the expenses incurred to make the product or service and can be broken down into cost per unit and number of units sold . 

The formula can further be broken down into:

            Profit (or Loss) = (price per unit x number of units sold) – (cost per unit x number of units sold)

There are other ways to break down revenue and cost depending on the case question.

• Revenue can be broken down by product or service line, customer type, or geographic region (e.g., North American, Europe, Asia)
• Costs can be broken into fixed costs and variable costs, or components such as overhead, salary, etc.

It is often helpful to break costs down into fixed and variable to solve consulting cases, and understanding the difference is important. Fixed costs, like rent for a store or the cost of equipment, are incurred regardless of how many units a company sells; whereas variable costs are only incurred with the production of each additional unit. Because of this, it can be helpful to sell incremental units even at a loss for a short period of time if it helps cover fixed costs.

So the profitability formula can also be written as:

            Profit (or Loss) = (price per unit x number of units sold) – (fixed + variable costs)

P rofitability example:

Your client, a manufacturer, is facing a decline in profits. Your client wants your help solving this problem. We’ll use this example to demonstrate all the formulas in this section.

The first step you could take is to calculate the past year’s profit given the following information:

• Number of units sold = 1 million
• Price per unit = $10
• Cost per unit = $8

          Profit (or Loss) = ($10 x 1 million) – ($8 x 1 million)

          Profit = $2 million

Profit margin formula:

Profit margin indicates how many cents of profit the company generated for each dollar of sale. It’s typically used to measure the financial health of a company . 

You can compare the profit margin of a company against its historical margins to evaluate whether its current performance is better or worse than past performance. You can also compare it against companies in the same industry to evaluate whether its financial performance is stronger or weaker.

Profit margin can be calculated using the formula:

          Profit margin = (Profit / Revenue ) *100%

Profit margin example:

To calculate the profit margin, first, you need to calculate company revenues as follows:

            Revenue = 1 million x $10

           Revenue = $ 10 million

You can now calculate the profit margin as follows:

            Profit margin = ($2 million / $10 million) x 100%

           Profit margin = 20%

Note you can combine both the formulas for faster calculation.

Market share formula:

Market share is the size of the company in relation to the size of the industry in which it operates, where size is typically measured in annual revenues. It is used to compare the size of a company to its competitors and the industry as a whole. It can be used in market entry cases because industries with a lot of small competitors are generally easier to enter than ones with only a few big competitors. It’s also used in profitability cases because, in general, companies with a large market share also have more market power to do things like set prices.

Market share can be calculated using the following formula:

            Market share (%) =total company revenue / total industry revenue  

Market share example:

Using the example from above, say you decide to determine the company’s market share as part of your analysis. In this example, the industry has annual revenues of $ 200 million.

            Market share (%) = $ 10 million / $ 200 million

           Market share = 5%

Growth Rate Formula:

This refers to the specific change of a variable within a specific period of time. Growth rates can be used in assessing the financial performance of a company over time. For example, high revenue growth rates would likely be a sign of strong financial performance. High cost growth rates may be a sign that a company is having financial trouble.

The growth rate is calculated using the formula:

            Growth rate (%) = (New – Old) / Old

Growth rate example:

To calculate the manufacturer’s revenue growth rate. Last year’s revenue was $ 9.5 million therefore the revenue growth rate is:

            Revenue growth rate = ($10 million – $9.5 million) / $9.5 million

            Revenue growth rate =5%

You can assess whether a company’s growth rate is strong by comparing it to other growth rates such as:

• The company’s growth in the prior year.
• The growth of the market or of competitors.
• The rate of inflation.

Mature companies are likely to see single-digit growth rates unless they launch a very successful new product or they acquire a company. On the other hand, startup investors typically expect double- or triple-digit annual growth during a company’s early years.

Return on investment formula:

Return on investment (ROI) is a profitability metric that indicates how well an investment performed (or will perform). It can be used to compare the profitability or efficiency of an investment or decide which of alternative investments to make. 

ROI is calculated using the following formula:

            ROI (%) = Profit / Cost of investment

ROI example:

Suppose our manufacturer mentions that they purchased state-of-the-art machinery to make their product. It cost $8 million. You decide to calculate the ROI on this investment. 

            ROI  = $2 million / $8 million

           ROI=25%

Break-even formula:

Break-even is the point at which the total revenue and total costs are equal, meaning there is no loss or profit at that point. Break-even is typically used to help companies determine the minimum number of units that need to be sold to cover all the costs used to produce those units. 

An executive might want to know that they could break even at 100,000 units sold because if she thought they could sell more than that, it would be profitable to enter the market. If she thought they’d sell less, they wouldn’t enter the market.

Break-even can be calculated using the following formula:

              Breakeven (units) = Fixed costs  / (sales price – variable cost per unit)

Break-even example:

If a product required a $50,000 investment in equipment (a fixed cost), sold for $5, and cost $4 per unit in variable costs, its breakeven would be: 

              Breakeven (units) = $50,000  / ($5 – $4)

              Breakeven= 50,000 units

Payback period formula:

Managers may also look at the payback period on an investment or, in other words, how long it would take to earn back the cash required to enter a new business. This investment could be a new piece of equipment or a marketing campaign needed to create customer awareness of a new product. This is a different way of looking at the same question that the breakeven formula asks: is it worth my while to make this investment?

The payback period can be calculated using the following formula:

              Payback (years) = Investment cost / annual profit

Payback years example:

Using the same example, you decided to calculate the payback years of the new state-of-art machinery

            Payback (years)= $8 million / $2 million

           Payback = 4 years

Capacity of equipment:

The capacity of equipment is the maximum output or units a piece of equipment can produce with the available resources over a set period of time.

Capacity can be calculated using the following formula:

            Capacity (units) =Total capacity / Capacity required to make one unit

Capacity example:

To calculate the capacity of our manufacturer’s machinery, we’d need to know that it can produce a unit every 10 minutes and that the client operates 12-hour shifts.

              Capacity (units) = 12 hours x (60 minutes per hour) / 10 minutes

             Capacity = 72 units / day

The utilization rate of equipment:

Utilization rate is the percent of available time the equipment or machinery is actually used. It measures efficiency and can be used by companies to make informed decisions on timelines and inventory, or whether additional equipment is needed.

The utilization rate of equipment can be calculated by the following formula:

              Utilization rate (%) =Actual output / Maximum output

Utilization rate example:

Using the same example, imagine that the management tells you that in a 12-hour shift, the machine produces 50 units and there are two 45-minute breaks.

First, you would need to calculate the potential output.

               Actual hours of operation = 12 hours – 1.5 hours = 10.5 hours

               Potential output = (10.5 hours / 12 hours) x 72 units

               Potential output = 63 units

Then, calculate the utilization rate.

                Utilization rate = 50 units / 63 units

                Utilization rate = 79%

Utilization rates raise interesting issues in a case. It raises questions such as:

• If potential output is 63 units, why are only 50 being produced (e.g., machine downtime, worker errors), and what can be done to solve these problems?
• Could the company stagger employee breaks to get potential output up to 72 units from 63?

Case Interview 101, Part 3: Business Concepts You Need to Know

Here are some common business concepts that you need to know as you prepare for your interview.

Process : This is a set of actions or operations that lead to results (products or services).

This typically describes how a company makes its products or services. The steps can be performed by workers, equipment, or computers. In a case, this is mostly used in situations where a client would like to make their processes more efficient. For example, a client who is in logistics would like to reduce the cost of its operations by improving the efficiency of its processes, such as by reducing equipment downtime or scheduling deliveries according to time-saving routes. 

Best practices: Best practices are methods or techniques that are considered to be the working standards and guides in a given situation. 

In a business situation, best practices are used to benchmark companies against the standard and can serve as a roadmap on how to improve the efficiency of their operations.

Hypotheses: Tentative answers to a problem or an assumption based on some evidence. 

The hypothesis-driven approach is a common approach to solving problems in the consulting world because consultants don’t want to waste time fully researching all possible solutions. They want to move quickly to the most likely answer and then test whether it is or is not the best answer. This approach can be used to solve case interview questions where you first assume an answer to the case problem and check whether this is true or not through analysis. If it is not true, you revise your hypothesis.

Issue tree: This is a common approach in consulting used to solve complex problems.

An issue tree is used to break down complex problems into key components in a structured manner. In a case interview, you can use the issue tree to break down the client’s problem into manageable chunks or to break down a formula such as the profitability formula into key components.

Read our article for more information on Issue Trees .

MECE: MECE stands for mutually exclusive and collectively exhaustive . 

It is a way of bucketing problems, ideas, or solutions with no overlapping between the buckets and with each item having a place in one bucket only (mutually exclusive), and with the buckets including all possible items relevant to the context (collectively exhaustive). In a case interview, you can use MECE with the issue tree when breaking down problems or when identifying solutions for the client. MECE issue trees are considered the gold standard for problem-solving so this concept is very good to know. 

You can also use the concept of MECE when segmenting a market – for example, if you are sizing a market and intend to lay out different purchasing behavior assumptions for different customer segments. For example:

Customer segment                         Purchase frequency for items from coffee shops

Women under 30                             4 times per week, purchase includes food item plus beverage Men under 30                                     2 times per week, purchase includes only beverage Women 31 and over                         4 times per month, purchase includes only beverage Men 31 and over                                 3 times per month, purchase includes only beverage

Note how in this example, everyone would fall into one customer segment and only one customer segment. Read our article for more about MECE problem-solving .

Root causes: This is the core issue or main reason for a problem . It is used in problem-solving to identify solutions that appropriately address the problem. 

The term root cause is used to distinguish between symptoms of a problem, which may be obvious, and the underlying issue that needs to be solved, which may not be obvious. For example, a decline in sales volume is a symptom. The root cause could be high prices, poor product quality, product unavailability, or any number of other issues. You can’t fix the symptom of declining sales volume until you identify the root cause behind the problem. 

In a case interview, you’ll need to identify possible causes of the client’s problem and then ask questions and do analysis to identify the root cause. Once you do, you can make the most appropriate recommendations for the client.

Break-even analysis: This is the calculation used to determine the point at which the total revenue and total costs are equal meaning there is no loss or profit. 

In business situations, it helps determine at which point the business, investment, or new product or service will become profitable. In case interviews, you can use the break-even analysis to determine whether a client should make a certain investment, say in machinery or a new product line, based on how likely it is that they’ll exceed the break-even threshold.

Case Interview 101, Part 4: Common Types of Case Interviews

In this section, we will review 4 common types of case interviews.

Market-sizing Questions

Market-sizing questions typically appear in cases where clients want to grow or expand their business such as market entry or profitability cases. The client either wants to understand the market size of the current business or of a potential new product line or geography or customer group to understand whether it is big enough to be interesting. 

Sample case questions

“How many cups of coffee does Starbucks sell in a day?” “Estimate the fleet size of Delta Airlines.” “Estimate market size for air-conditioners in New York.”  “Estimate market size for an anti-smoking pill in the U.S.”

You are not expected to know the exact answer to market-sizing questions. Instead, the interviewer wants to see that you can use simple math and logical deduction to build out an answer. For these questions, it is good to memorize a few facts that will help you make assumptions. For example, a good place to start is the population of the U.S. or the population of a U.S. city (or country and city that you live in). 

For more information and examples, read our article on Market-sizing Cases .

Revenue Growth Case Interviews

In revenue growth cases, the client typically wants to grow their business. This can be done by increasing revenue of the current product/service line, by adding a new product/service line, or by selling to a new type of customer or in a new geography. 

They could do this by building a new offering, buying another company, or partnering (joint venture) with another company that already offers what they want to sell. 

“A manufacturer sees its revenue stagnating. It wants to know whether raising price or selling more units is a better path to growing revenue, and how to pursue it.”

“A local theater house thinks there is an opportunity to expand their current offerings to the very loyal client base. What new product or service could they offer their customers? What would be the impact on revenue from expanding their offerings?”

“A regional fast-food chain, serving hamburgers and fries, is experiencing increasing demand outside of its main regions of operation and wants to expand. What regions would have the biggest impact on its revenue?”

You should remember that there are multiple ways to achieve revenue growth. One thing to consider is the client and industry context when tackling revenue growth questions. For example, does the client have a good market size in the industry? Does the client have the capability to offer new products/services? Is the industry highly competitive?

For more information, read our article on Revenue Growth Cases .

Market Entry Case Interviews

In market entry cases, the client wants to know if they can enter a market and be profitable. For example, entering a different geography, new demography, or new product/service line. (Note, there can be overlap between revenue growth cases and market entry cases.)

“A U.S.-based consumer electronics manufacturer is thinking of expanding into emerging markets. What is the potential revenue growth if they choose to expand into India?”

“A telecom operator is looking to diversify their presence in the U.S. and wants to enter the video streaming market. How can they capture a significant market share?”

“A renewable energy company that specializes in large equipment such as windmills wants to enter the retail market and sell smaller equipment directly to individual homes. They would like to know if this is a good idea.”

There are a number of frameworks you can build off of to tackle a market-entry case. For example, Porter’s Five Forces, Business Situation Framework or 3C&P (customer, competition, company, and product), and Supply & Demand among others. It is key to consider the “new” market context as well as the client context to enter this market. 

To find out more on this, read our article on The Market Entry Framework .

Cost Optimization Case Interviews

Cost optimization cases or questions can be part of a profitability case where a client is experiencing declining profitability or when a client wants to improve efficiency.

“A national hotel chain has seen its operational costs significantly increase over the last year and would like you to figure out why.”

“A juice manufacturer has been experiencing a steady increase in revenue over the past 5 years however their cost has been increasing at a faster rate, meaning the profits have not grown as expected. What is the root cause of the significant increase in cost?”

“A tour company would like to reduce their costs due to the falling number of tourists over the past few years. What ways would you recommend for them to reduce their costs?’

For cost optimization cases, remember to break down the cost components. For example, you can break them down into fixed and variable costs or cost of goods sold and operational costs and then brainstorm the categories of each that will likely apply to the company at hand. This will make it easier to identify what costs should be reduced or eliminated.

Check out Types of Case Interviews article for more detail on these types of cases and more.

Why Do Top Consulting Firms Use Case Interview Questions?

Management consultancies are not the only types of firms that use case interview questions to evaluate candidates. 

Investment banks, consumer marketing companies, and others use the case interview structure in their interview process.

Because case interviews show how a candidate would problem solve in real time. 

Solving complex, ambiguous problems is at the heart at what consultants do every day.

This type of interview question mimics the analytic process a consultant might go through in a 3-month project, but it does it in 30 minutes, the time allowed in a typical interview. 

The interviewer can probe whether a candidate’s approach is well-structured, creative, and displays good business sense.

How Do Consulting Recruiters Evaluate Candidates?

The main thing that recruiters are looking for in case study interviews is whether or not they’d feel comfortable putting a candidate in front of a client. To assess that, they ask themselves these questions:

• Is this person able to do the job? Do they have the analytic skills to solve tough business problems?
• Is this person client-ready? Are they knowledgeable, professional, and confident enough to work effectively with client staff and leaders?
• Is this someone I’d want to work with? This interview question is sometimes referred to as the airport test. It comes down to, “Would I want to be stuck in an airport with this person if the weather was bad and our flight was delayed?” It assesses whether an individual is smart, fun and passionate about the projects they take on.
• Is this person coachable? No one expects a recruit to know the answer to every thorny business issue right out of undergrad, or even right out of business school, but they do want someone who is willing and able to take suggestions and improve their analysis. Show you are coachable by listening for feedback as you answer a case study interview question and using suggestions to steer you toward the right solution.

Consulting Case Prep Takes Time – Start Early

If you walk into your first consulting interview without having practiced case study interviews beforehand, you’re in for a painful experience. Case questions can cover any industry and multiple different types of business problems, so you’re unlikely to get lucky and know the answer.

We suggest your start your consulting case prep a few weeks before your interview. Starting with more lead time is even better. This will allow you to watch/read through a few consulting cases to get a sense for what to expect (continue to our case videos below for one example!) It will also give you time to find a couple friends or classmates who are also applying to top consulting firms. You can give each other mock case interviews and be even more prepared.

Learn How to Case Quickly by Mastering Each Part of the Case

When you’re starting your consulting interview prep, it’s important to remember that the “right answer” is not simply a conclusion, but the methodical, the well-structured process used to reach the conclusion. 

To answer a case question correctly, you must:

Step 1: Understand the question you are being asked.

After your interviewer describes the client this case interview will involve and the problem they face, you should repeat this information back to them in your own words. 

This can feel awkward when you practice your first case, but it will help you in the long run.

If you don’t have the client and their problem straight, you could spend a lot of time answering the wrong question. If that happens you will not be moving forward to second round interviews no matter how elegant your analysis is.

Example: Our client is a fast-food retailer that has seen decreasing sales revenue over the past couple of years. They want your help in understanding what they can do to improve sales.

Step 2: Take time to think through all the key aspects of the problem.

Ask for a moment to consider your approach to solving the client’s problem. During this time, write down what you want to learn about the client’s situation before you answer the interview question.

Your approach can lean on business frameworks you’re familiar with during your case interview preparation. 

For instance, in the example of a fast-food chain with declining sales, you should break sales down into price and unit volume to understand whether the client is not selling enough units of their products or whether prices have fallen (or both!)

But you don’t need to use familiar frameworks. In fact, it’s best to develop your own structure for breaking down the problem as it shows you can solve a case without forcing a standard framework on the problem.

For more information on business frameworks, you might want to become familiar with during your case study preparation, see  Case Interview Frameworks .

Step 3: Ask pertinent questions and use the answers to form hypotheses.

After you brainstorm key aspects of the case problem and structure your approach to solving it, share your approach with your interviewer.

If the interviewer suggests a place to start your analysis, follow their lead.

Otherwise, suggest the best place to start digging into the case.

Make sure the questions you ask the interviewer touch on all the key aspects of the problem you identified including the client’s internal organization, the market for their product, and their competition.

Step 4: Summarize your case interview with a persuasive conclusion. 

Once you’re confident you have enough information to understand the case and what needs to be done to solve the client’s business problem, you’ll conclude the interview with a logical summary outlining the problem, key conclusions you’ve reached, and providing a persuasive recommendation on how you’d help the client resolve it.

Below, we’ll go into more depth on how to address each of these 4 points in a case.

Questions to Ask Yourself Before Diving Deeper into Case Prep

Right now, you may be thinking to yourself that consulting interviews sound impossibly difficult. Or you may think that they sound like interesting business problems that you’d enjoy solving. 

Perhaps you’re not sure.

If you think that answering case interviews is not something that would come naturally to you, don’t worry, you’re not alone! 

Getting good at consulting interviews requires a lot of preparation.

Before you commit to putting in the time required to prepare for the management consulting interview process, you should ask yourself if a career in management consulting is right for you.

Key Questions to Ask Yourself Before Pursuing a Career in Consulting

• Do you enjoy solving the types of business problems asked in case interviews?
• Do you have a background in business principles or are you willing to invest the time it will take to develop one?
• Are you passionate about pursuing consulting as a career?

Management consulting jobs might pay well and provide the opportunity to pursue attractive careers, but if you don’t like solving business problems, you probably won’t like the work you’ll do as a consultant. If you don’t enjoy analyzing business cases, save yourself a lot of preparation time and frustration. 

Focus on career options that better meet your interests.

Or, perhaps solving business problems with smart, driven professionals sounds like it’s your dream job. 

If so, move onto the deeper dive into case prep below! 

Case Interview Prep – Diving Deeper

If you’re here, we’re assuming you’re serious about investing time in preparing for a career in management consulting. 

The best way to get smarter about  answering case interview questions is to master this four-part approach.

How to Answer a Consulting Case Interview –  a 4 Part Approach

The 4 parts to answering a case interview are:

• Opening  – This is where you make sure you understand the client’s problem.
• Structure  – This is where you brainstorm all factors relevant to the problem and organize them to ensure you address them in a complete and logical manner.
• Analysis  – This is where you gather data to identify which of the factors related to the business case are the most important. You’ll use this data to create a recommendation for your client.
• Conclusion  – Here, you present your recommendation to “the client” (your interviewer), in a well-structured and persuasive manner.

Case Interview Prep Part 1: The Opening

As we saw in the video above, the opening of a case question is a description of a client and the problem they’re facing. Davis repeated back to the interviewer the type of business the client was in and and their business problem.

Remember, this clarification is an important step in the process.

If you did not remember that the client was a top-three beverage producer and answered the question as if the client was a start-up, your answer would ignore the manufacturing and distribution infrastructure the company already had in place to launch its new product.

That would make your answer completely wrong.

During this portion of the interview, you can ask any clarifying questions you need to. If something is not clear—the client’s product or industry, or the problem they want to solve —ask !

Nailing the opening is probably the easiest part of case prep. Get this right, and you’ll start each case off strong.

Case Interview Prep Part 2: Structure

Once Davis clarified the problem, he asked for a moment to prepare her response. In the structure phase of the case interview, there’s silence for several moments.

As with clarifying the question, this can feel awkward.

But asking for this time will show the interviewer that you’re carefully structuring your problem-solving approach.

It will also ensure that you are not quickly addressing a couple of aspects of the business problem but ignoring others, potentially ones that are critical to solving the client’s problem.

Some quick brainstorming is useful here, but also take a step back to maker sure you consider all aspects of the client’s business, its customer demand, and the competition. 

Organize your questions into a comprehensive approach to address all key aspects of the problem.

Mastering the structure phase of the interview is not as easy as the opening, but it’s critical to ensure you have the structured problem-solving approach that will lead you to the right answer to the case.

Focus on this aspect of case interview preparation until you can structure almost every case right.

Case Interview Prep Part 3: Analysis

In the third part of the case study interview, you’ll dig in and analyze the problem.

After Davis outlined his problem-solving approach, the interviewer told him that the client wanted to understand the beverage market and customer preferences to assess the potential success of the product launch.

The interviewer then provided a chart with helpful data.

This part of the interview is important because gives you the data that will help you close down aspects of the case that aren’t at the heart of the problem you need to solve and to better understand key drivers that will point to the solution.

But you’ll also need to do some consulting math .

You should also refer back to the problem-solving structure you laid-out earlier in the interview to make sure your analysis is comprehensive. You don’t want to get lost down one rabbit hole and ignore other important aspects of the problem.

During this portion of the interview, you’ll be assessed on whether you asked relevant questions, have well-reasoned insights into the client problem, and whether you could lead a case like this if you were hired by the firm.

Many consulting candidates find that the analysis phase of the interview is the toughest of the 4 parts.

You need to balance doing consulting math calculations with interpreting data and make sure you cover all aspects of the problem you identified in the structure phase of the case. 

Stick with this aspect of case preparation until you’re an expert at it–it will pay off in your interviews. 

Case Interview Prep Part 4: Conclusion

Davis concluded the case with a direct answer to the case study interview question as it was initially asked.

This answer should be both persuasive and logical based on all the information gathered over the course of the interview. Your answer should also include the next steps your client should undertake.

During the conclusion, you’ll be assessed on whether you present a well thought-out solution based on the relevant facts of the case.

Like the opening, mastering the conclusion is not difficult. Take you time to nail this aspect of case prep anyway as leaving your interviewer with a strong impression of your casing capabilities is important.

Effective Case Interview Prep: The Bottom Line

The case study interview is not as complex as it seems if you break it into 4 parts.

Practicing each part of the case on its own will make your consulting interview preparation both more efficient and more effective.

Now that you’re familiar with the 4-part approach to a case interview, the next thing to learn is the 4 different formats case interviews can take.

4 Formats for Case Interviews

There are four formats a case interview can take:

• Interviewer-led – In this case interview format, a candidate will still be expected to identify and structure the key elements of  a thorny business issue, and then present them to the interviewer. But after they do, the interviewer will direct them to first address a particular aspect of the case. This interview format is typically used in McKinsey cases.
• Written interview – This is not a common interview format but can be common for particular companies and offices. You will be given a packet of PowerPoint slides and time to review them. During this time, you’ll prepare a presentation using the slides you choose from the ones provided as well as others you create, and you’ll then present it to a panel of interviewers. Written interviews are frequently used by boutique consulting firms and regional offices of larger firms such as Bain’s China offices. For more information, see this article on written case interview.
• Group interview – Multiple candidates are brought in to discuss a case together and then present their solution to an interviewer. The group case is also not a frequently used interview format. For more information, see this article on group case interview.

While the candidate-led consulting interview is the most frequently used format, you’ll probably see more of the interview-led interview format in McKinsey interviews.

You should also be aware of the written and group interview formats so that if you get one during the case interview process, you’re not caught by surprise. But don’t spend a lot of time on preparation for that type of interview unless you’re informed you’ll have one.

Congratulations!

8 thoughts on “A Comprehensive Guide to Case Interview Prep [updated 2024]”

In the math calculations of the analysis portion, why was it that there were 8 cans per gallon? Where did that number come from?

Hey, Tonia! Thanks for your question.

In the case, we’re given that the size of the market for US sports drinks is 8 billion gallons. Electrolyte drinks are 5% of this total or .4 billion gallons which equals 400 million gallons.

We’re also given that the product size for drinks in this market are 16 ounces. And in our breakeven analysis, we find out we need to sell 400 million bottles (or cans) to break even. We need to do a conversion to compare our breakeven point of 400 million bottles to the 400 million gallon market size to see what market share we would have to achieve to break even.

Conversion: 1 US gallon = 128 ounces. 128 ounces/ gallon divided by 16 ounces/ bottle = 8. We can fill 8 bottles for each gallon of electrolyte drink we produce. So 1 gallon is 8 bottles (or cans) manufactured by our client.

We divide the 400 million bottle (or can) breakeven point by 8 to get to 50 million gallons. We compare the 50 million gallon breakeven point to the 400 million gallon market size to see that we need to capture 12.5% market share.

Note: In answering this question, I noticed that a UK gallon = 160 ounces, so if you are using UK gallons you will get a different answer!

I hope that helps! Sorry about the confusion between US ounces/gallon and UK ounces/gallon!

Hi, what resources are you typically allowed to use during (virtual) case interviews? Such as a pen, paper, calculator etc.

You’re typically allowed a pen and paper in a virtual case interview but NOT a calculator. Part of what your interviewer is testing for is your quantitative skills, so they want to see that you can do calculations in your head or on paper. See our article on virtual case interviews , for more info. Also, we have an article on practicing your case interview math .

Best of luck!

Can you please explain the ROI formula? I do not understand why (2m-8m)/8m = 25%. That calculation gets a result of -75%

Shouldn’t the formula just be (net profit)/(cost of investment)?

George, thanks for pointing this out! The formula was incorrect, and should be Profit/cost of investment. The correct answer is 25%.

All the best, MCO

thanks for information

great information

Secrets to a successful case-study interview

January 9, 2023

Prepping for (and maybe fretting) the case-study interview?

While this kind of interview may appear intimidating, consider this: The interviewer really wants you to do well.

So, shake off the nerves, relax and have fun.

Tips for standing out in the case-study interview: 

• Take your time; don't rush it.  Talk through the problem. If you can't make sense of it, take a moment and allow yourself some time to process what you've been missing. If you get stuck, get creative. Don't let yourself get bogged down; rely on your ingenuity. 
• Ask questions.  You can always ask your interviewer to define an acronym or to repeat or confirm details. If the interviewer asks, “How do we achieve success?”, don’t be afraid to ask, “What does ‘success’ mean to you? Is it turning a profit? Raising the company’s profile?” When you work on a client project, you need to ask questions to figure out what the problems might be, and the same applies here. The interviewer is your biggest asset in the room. They have the information you need to “solve the case” successfully. Use them wisely!
• Be flexible.  The focus of a case-study interview may vary. So, be prepared to participate in whatever discussion the interviewer has in mind. They may spend the first half of the interview asking about your previous experience, or they may dive right into the case study at the start. The bottom line: Be flexible, and be ready to discuss the work you do and how you do it.
• Use visual aids.  Don’t be afraid to use pen and paper, sketch out your thoughts, and talk through the problem at hand if it helps you get your ideas across. What matters most is demonstrating that you can solve problems.
• Focus on impact.  Inventory the information you have, and then dive in where you can have the most impact. Don’t forget to discuss your thought process and explain your assumptions.
• Tell a story.  Your experience has helped you progress in your career and education; use that experience. For example, in a business case study, you could bring your experience as a traveler to a case about a hypothetical airline. Your individuality is important. Your unique insights will serve you well when you’re interviewing.
• Pay attention to cues.  If the interviewer says something, it probably means something. Don’t dismiss seemingly extraneous details. For example, the interviewer might say, “The case is about a retailer who wants to increase the value of a company it purchased, and the owner loved the brand when growing up.” The purpose of that detail is to indicate that turning around and selling the asset is not an option for making it profitable, because the owner is attached to it.

Preparing for the job you want can take time, but it’s a worthwhile investment—especially when you receive an offer.

Your ideas, ingenuity and determination make a difference.

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.

Avg. Time: 2 hours

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.

• Yale (2013)

Consulting casebooks are documents that MBA consulting clubs put together to help their members prepare for consulting case interviews. Consulting casebooks provide some case interview strategies and tips, but they mostly contain case interview practice cases.

While consulting casebooks contain tons of practice cases, there is quite a bit of variety in the sources and formats of these cases.

Some practice cases are taken from actual consulting interviews given by consulting firms. These are the best types of cases to practice with because they closely simulate the length and difficulty of an actual case interview. Other practice cases may be written by the consulting club’s officers. These cases are less realistic, but can still offer great practice.

The formats of the practice cases in consulting casebooks also vary significantly.

Some practice cases are written in a question and answer format. This type of format makes it easy to practice the case by yourself, without a case partner. Other practices cases are written in a dialogue format. These cases are better for practicing with a case interview partner.

MBA consulting casebooks can be a great resource because they are free and provide tons of practice cases to hone your case interview skills. However, there are several caveats that you should be aware of.

• Similarity to real case interviews : Some cases in MBA consulting casebooks are not representative of actual case interviews because they are written by consulting club officers instead of interviewers from consulting firms
• Quality of sample answers : While consulting casebooks provide sample solutions, these answers are often not the best or highest quality answers
• Ease of use : Consulting casebooks are all written in different formats and by different people. Therefore, it can be challenging to find cases that you can consistently use to practice cases by yourself or with a partner

Therefore, we recommend that you first use the case interview examples listed in this article and wait until you’ve exhausted all of them before using MBA consulting casebooks.

How to Use Case Interview Examples to Practice Case Interviews

To get the most out of these case interview examples and maximize your time spent on case interview practice, follow these three steps.

1. Understand the case interview structure beforehand

If case interviews are something new to you, we recommend watching the following video to learn the basics of case interviews in under 30 minutes.

Know that there are seven major steps of a case interview.

• Understanding the case background : Take note while the interviewer gives you the case background information. Afterwards, provide a concise synthesis to confirm your understanding of the situation and objective
• Asking clarifying questions : Ask questions to better understand the case background and objective
• Structuring a framework : Lay out a framework of what areas you want to look into in order to answer or solve the case
• Kicking off the case : Propose an area of your framework that you would like to dive deeper into 
• Solving quantitative problems : Solve a variety of different quantitative problems, such as market sizing questions and profitability questions. You may also be given charts and graphs to analyze or interpret
• Answering qualitative questions : You may be asked to brainstorm ideas or be asked to give your business opinion on a particular issue or topic
• Delivering a recommendation : Summarize the key takeaways from the case to deliver a firm and concise recommendation

2. Learn how to practice case interviews by yourself 

There are 6 steps to practice case interviews by yourself. The goal of these steps is to simulate a real case interview as closely as you can so that you practice the same skills and techniques that you are going to use in a real case interview.

• Synthesize the case background information out loud : Start the practice case interview by reading the case background information. Then, just as you would do in a live case interview, summarize the case background information out loud
• Ask clarifying questions out loud : Just as you would do in a live case interview, ask clarifying questions out loud. Although you do not have a case partner that can answer your questions, it is important to practice identifying the critical questions that need to be asked to fully understand the case
• Structure a framework and present it out loud : Pretend that you are in an actual interview in which you’ll only have a few minutes to put together a comprehensive and coherent framework. Replicate the stress that you will feel in an interview when you are practicing case interviews on your own by giving yourself time pressure.

When you have finished creating your framework, turn your paper around to face an imaginary interviewer and walk through the framework out loud. You will need to get good at presenting your framework concisely and in an easy to understand way.

• Propose an area to start the case : Propose an area of your framework to start the case. Make sure to say out loud the reasons why you want to start with that particular area
• Answer each case question out loud : If the question is a quantitative problem, create a structure and walk the interviewer through how you would solve the problem. When doing math, do your calculations out loud and explain the steps that you are taking.

If the question is qualitative, structure your thinking and then brainstorm your ideas out loud. Walk the interviewer through your ideas and opinions.

• Deliver a recommendation out loud : Just as you would do in a real case interview, ask for a brief moment to collect your thoughts and review your notes. Once you have decided on a recommendation, present your recommendation to the interviewer.

3. Follow best practices while practicing case interviews :    

You’ll most likely be watching, reading, or working through these case interview examples by yourself. To get the most practice and learnings out of each case interview example, follow these tips: 

• Don’t have notes or a calculator out when you are practicing since you won’t have these in your actual interview
• Don’t take breaks in the middle of a mock case interview
• Don’t read the case answer until you completely finish answering each question
• Talk through everything out loud as if there were an interviewer in the room
• Occasionally record yourself to understand what you look like and sound like when you speak

4. Identify improvement areas to work on

When the case is completed, review your framework and answers and compare them to the model answers that the case provides. Reflect on how you could have made your framework or answers stronger.

Also, take the time to reflect on what parts of the case you could have done better. Could your case synthesis be more concise? Was your framework mutually exclusive and collectively exhaustive? Could your math calculations be done more smoothly? Was your recommendation structured enough?

This is the most important part of practicing case interviews by yourself. Since you have no partner to provide you feedback, you will need to be introspective and identify your own improvement areas.

At the end of each practice case interview, you should have a list of new things that you have learned and a list of improvement areas to work on in future practice cases. You’ll continue to work on your improvement areas in future practice cases either by yourself or with a partner.

5. Eventually find a case partner to practice with

You can only do so many practice case interviews by yourself before your learning will start to plateau. Eventually, you should be practicing case interviews with a case partner.

Practicing with a case partner is the best way to simulate a real case interview. There are many aspects of case interviews that you won’t be able to improve on unless you practice live with a partner:

• Driving the direction of the case
• Asking for more information
• Collaborating to get the right approach or structure
• Answering follow-up questions

If you are practicing with a case partner, decide who is going to be giving the case and who is going to be receiving the case.

If you are giving the case, read the entire case information carefully. It may be helpful to read through everything twice so that you are familiar with all of the information and can answer any question that your partner asks you to clarify.

As the person giving the case, you need to be the case expert.

You should become familiar with the overall direction of the case. In other words, you should know what the major questions of the case are and what the major areas of investigation are. This will help you run the mock case interview more smoothly.  

Depending on whether you want the case interview to be interviewer-led or candidate-led, you will need to decide how much you want to steer the direction of the case.

If your partner gets stuck and is taking a long time, you may need to step in and provide suggestions or hints. If your partner is proceeding down a wrong direction, you will need to direct them towards the right direction.

Where to Find More Case Interview Examples

To find more case interview examples, you can use a variety of different case interview prep books, online courses, and coaching. We'll cover each of these different categories of resources for more case interview practice in more detail.

Case Interview Prep Books

Case interview prep books are great resources to use because they are fairly inexpensive, only costing $20 to $30. They contain a tremendous amount of information that you can read, digest, and re-read at your own pace.

Based on our comprehensive review of the 12 popular case interview prep books , we ranked nearly all of the case prep books in the market.

The three case interview prep books we recommend using are:

• Hacking the Case Interview : In this book, learn exactly what to do and what to say in every step of the case interview. This is the perfect book for beginners that are looking to learn the basics of case interviews quickly.
• The Ultimate Case Interview Workbook : In this book, hone your case interview skills through 65+ problems tailored towards each type of question asked in case interviews and 15 full-length practice cases. This book is great for intermediates looking to get quality practice.
• Case Interview Secrets : This book provides great explanations of essential case interview concepts and fundamentals. The stories and anecdotes that the author provides are entertaining and help paint a clear picture of what to expect in a case interview, what interviewers are looking for, and how to solve a case interview.

Case Interview Courses

Case interview courses are more expensive to use than case interview prep books, but offer more efficient and effective learning. You’ll learn much more quickly from watching someone teach you the material, provide examples, and then walk through practice problems than from reading a book by yourself.

Courses typically cost anywhere between $200 to $400.

If you are looking for a single resource to learn the best case interview strategies in the most efficient way possible, enroll in our comprehensive case interview course .

Through 70+ concise video lessons and 20 full-length practice cases based on real interviews from top-tier consulting firms, you’ll learn step-by-step how to crush your case interview.

We’ve had students pass their consulting first round interview with just a week of preparation, but know that your success depends on the amount of effort you put in and your starting capabilities.

Case Interview Coaching

With case interview coaching, you’ll pay anywhere between $100 to $300 for a 40- to 60-minute mock case interview session with a case coach. Typically, case coaches are former consultants or interviewers that have worked at top-tier consulting firms.

Although very expensive, case interview coaching can provide you with high quality feedback that can significantly improve your case interview performance. By working with a case coach, you will be practicing high quality cases with an expert. You’ll get detailed feedback that ordinary case interview partners are not able to provide.

Know that you do not need to purchase case interview coaching to receive a consulting job offer. The vast majority of candidates that receive offers from top firms did not purchase case interview coaching. By purchasing case interview coaching, you are essentially purchasing convenience and learning efficiency.

Case interview coaching is best for those that have already learned as much as they can about case interviews on their own and feel that they have reached a plateau in their learning. For case interview beginners and intermediates, it may be a better use of their money to first purchase a case interview course or case interview prep book before purchasing expensive coaching sessions.

If you do decide to eventually use a case interview coach, consider using our case coaching service .

There is a wide range of quality among coaches, so ensure that you are working with someone that is invested in your development and success. If possible, ask for reviews from previous candidates that your coach has worked with.

How to ace your case study interview

Our tips will help you approach your case interview with confidence

By Kelly Tavakoli and Rachel Beckerman

For most prospective West Monroe candidates, the case study interview is perhaps the most daunting part of the application process. Why? Because our case studies don’t simply assess what you know – the technical or industry capabilities that one can study for – they assess how you think.   And that’s on purpose. For one thing, it levels the playing field, allowing candidates with diverse backgrounds and skillsets with the opportunity to succeed. For another, venturing into the unknown – and relying on the ability to “think like a consultant” – mirrors what we at West Monroe often have to do on the job.   In our 45-minute interviews, candidates are given a story-driven case study pulled right out of a real-life West Monroe project; from there, the candidate will act as a consultant on the project. We’re looking for our candidates to demonstrate critical thinking (i.e., the ability to gather and process information), problem solving (i.e., coming up with a solution that has the most impact), and communication skills (i.e., expressing thoughts with enthusiasm and confidence).   Just because we’re more focused on seeing how you think doesn’t mean you can’t prepare. That’s why we’ve outlined three key pieces of guidance for prospective candidates. Follow these, and you’ll be well on your way to acing your case study interview.

1. Don’t jump to the solution

We see it all the time: candidates receive their case study (i.e., their “problem”) and try to jump straight to the solution. It’s a natural instinct, especially in a nerves-inducing situation like a job interview. But in our experience, the candidates who do that tend miss important steps along the way. They’re so laser-focused on the end result, they don’t have time to think about how to get there: for instance, confirming the priorities of various stakeholders, mitigating disagreements about those priorities, or establishing the processes that will make their solution have a real impact. By solely concentrating on the solution, they can miss the big picture view of where each element fits along the way, and aligns with the organization’s goals.   After all, there’s no one “right” answer with these case studies, or in our work. It’s more often about developing processes, ensuring alignment, creating efficiencies, and providing a roadmap to our clients.   Thus, the best candidates often take a moment to pause, read over the case study, and ask direct, specific questions of the client/interviewer. They then concisely summarize the problem statement before launching into the problem-solving.

2. Communicate your thoughts in an organized fashion—using a framework that allows for flexibility

We suggest candidates come prepared to use a framework that allows for ample room for flexibility and creativity—one that won’t limit a candidate’s ability to think or react dynamically to the more open-ended case studies we employ.   We recommend one that helps evaluate the different components and priorities of a client: people (like human capital management, company culture), process (such as organizational structures, internal policies, lines of communication, etc.), and technology (that is, the digital tools that can help a client meet its goals).   For instance, in mergers it’s crucial to make sure the two companies’ cultures are aligned, that they establish new and efficient processes to make agile decisions, and that they consolidate technology amid the transition. The success of one depends on the success of another, and requires cross-functional coordination between different areas of the business – making sure technologies and the people who use them are not siloed, and can seamlessly talk with one another.   Candidates who understand how these buckets work with one another – and why aligning them is key to a client’s success – can effectively use them to organize their thoughts as they move through the case study. This framework can also help candidates succinctly summarize their thoughts at the end of the exercise –something our strongest candidates do consistently. 

3. Make sure you can back up your conclusions 

One byproduct of focusing solely on the solution is that interviewees often lack the evidence to support their conclusions. They provide surface-level responses and, when pressed, can’t back them up – or revert to buzzwords or jargon to cover up for not having a solid answer.   In a 45-minute interview, of course, it’s impossible to write down or even visualize all supporting evidence. But those who are engaged in the process of problem solving – who “think like a consultant” – are more capable of thinking on their feet. They’ll have gotten to the solution only by way of mapping out their journey to get there, which they can draw on when asked the tough questions.   It’s the difference, for instance, between saying, “an implication of adopting this digital transformation plan is that we will have to restructure our workforce” and articulating why that must (or should) be the case, how an organization might make those decisions, and what the alternatives or options for doing so may be. Following step one and not jumping to a solution should put you in a good position to discuss these issues as you’ve already assessed the problem from multiple angles.    We know case study interviews can be daunting – especially in a virtual environment, where the ability to whiteboard and connect with your interviewer may be more difficult. Still, it’s a vital part of our hiring process, allowing candidates to showcase the critical thinking, problem-solving, and communication skills they’ll need on the job.   We hope these tips help you feel more confident heading into a case study interview.

Traditional rondavel building patterns, designs and materials have changed due to urbanisation, economic status, globalisation, and modernisation. There is limited understanding of how the architectural change has impacted the utilisation of rondavel space. This study uses the concept of habitus to understand whether the changing design of traditional rondavels has influenced their utilisation, based on a case study of the Mbhashe Local Municipality in the Eastern Cape province, South Africa. The data was collected using semi-structured interviews. The findings reveal the habitus of the AmaXhosa people on how they utilise traditional rondavels (family house) for childbirth, placing a deceased’s coffin, sleeping, seating, food preparation, serving and storage, keeping the spear, hosting ceremonies, communicating with ancestors, and interacting with the living. While the influence of contemporary architecture has changed the construction of rondavels, the inhabitants have not resisted changes to the architecture or cultural values as they have found different ways to adapt. Certain old dispositions are adaptable to contemporary structures, but some people are uninterested in adapting elements to the contemporary rondavel. Some habits of utilising traditional rondavels cannot be adapted to the contemporary rondavel because of health and medical innovations.

Introduction.

Based on archaeological evidence, rondavels have existed since pre-colonial times as a prime settlement form in homesteads in much of South Africa and other African countries, including Botswana, Kenya, Lesotho and Eswatini (Schoenauer 2000 ; Steyn 2006 ). The rondavel is considered as a vernacular architecture: it is built using locally sourced material and forms part of a region’s culture and heritage (OpenHeritage 2016 ). Steyn ( 2006 :1) describes the rondavel as a “drum”, often built with mud and grass-thatched roofs (Fig. 1A ). They are popular indigenous settlements which are still prevalent in the rural areas. While most households have more than one rondavels (Fig. 1B ), some indigenous settlements are now roofed with zinc materials (Fig. 1B ). Going forward, this article refers to indigenous settlements as traditional rondavels.

Traditional rondavels were used for dwelling and hosting important customary rituals and celebrations in Africa (Steyn 2006 ). Modern day rondavels exist with flat-roofed rectangular buildings or structures built using cement and zinc roofs, which will be referred to as contemporary rondavel design henceforth (Van Vuuren 2017 ).

Steyn ( 2006 ) argues that the change is a result of urbanisation and economic status because people admire urban architecture and can afford their desired building materials. A study by Aikpehae et al. ( 2016 ) reveals that globalisation, urbanisation and modernisation transformed building patterns, designs and materials used for construction. They illustrate how Nigerian building patterns and housing have transformed because of the influence of colonisation (Aikpehae et al. 2016 ). Guerrieri ( 2020 ) adds that migration has allowed the export of architecture and urban planning models from one country to another; hence, we see the same style across countries. The global intercultural contact led to the change in dwellings in southern Africa (Frescura 1981 , 2015 ) where traditional dwellings were constructed using mud, wattle and thatch grass. Missionaries introduced contemporary building constructed using sun brick and mortar with corrugated iron sheet for roofing as well as highveld and parapet housing styles, the contemporary building is illustrated in Fig. 2 .

Tapiero et al. ( 2024 ) indicates that in Montesinho Natural Park, north-east of Portugal, residents had vernacular buildings constructed using locally available wood, slate stone tiles, lime mortar, schist and granite. The availability of industrialised material and decreasing traditional labour posed a threat vernacular buildings.

The following section discusses the evolution of the traditional and modern rondavel followed by the utilisation of rondavels by amaXhosa people, detailing the study area, research methods, results, discussion and conclusion.

Traditional and modern rondavel evolution

Early African dwellings were caves, stone-walled iron shelters or houses quickly erected and dismantled as nomadic societies followed herds of animals (Frescura, 1981 ; Moremoholo, 2021 ). Frescura ( 1981 ) explains the historical development of dwelling types, presented in Fig. 3 . The earliest traditional dwelling was a beehive hut also known as ngqu-phantsi . It was made up of stakes organised in a circle with their tops arched inward to a point. The stakes were then bound together by hoops and the frame was insulated with thatched grass (Walton, 1949 ). It is possible that the need for more living space resulted in the rondavel, which is a cone-on-cylinder rondavel with a wall and roof. Although its doorway was raised higher compared to the beehive hut, it was still lower than the height of a man. The material used to construct traditional rondavel was either a thatch roof with stones and mud bricks or sticks mixed clay and dung mortar or mud and wattle (Walton 1949 ; Frescura 1981 ; Oliver 2006 ; Moremoholo 2021 ; Onyejegbu et al. 2023 ). These vernacular dwellings were constructed using locally available materials (Tapiero et al. 2024 ).

The third iteration of dwelling development was influenced by Western ideas of hipped-on-cone, which had a linear floor plan, rooms divided into rows and triangulation of the thatch roof. The fourth dwelling type was an introduction of the highveld style with iron-sheet roofing and sun brick (Frescura 1981 ).

Western ideas influenced the cone-on-cylinder rondavel design and materials used which included the use of iron-sheet roofing and sun brick. Despite the Western influences, the traditional rondavel still exists while others have modernised (Moremoholo 2021 ; Onyejegbu et al. 2023 ). Vellinga ( 2006 ) notes that the traditional vernacular architecture has not vanished, but has rather merged with modern styles to suit the current circumstances. Tapiero et al. ( 2024 ) argue that the use of modern materials in construction does not compromise the values of the dwelling in the community. They also note that conserving vernacular architecture plays an essential role in the preservation of culture and sustainable practises by optimising energy usage (Tapiero et al. 2024 ). Onyejegbu et al. ( 2023 ) argue that some Nigerian households still have traditional mud huts that were built by their forefathers in commemoration of their culture, tradition and prowess.

Moremoholo ( 2021 ) used a case study of the Sotho community in Makgabeng, a rural area in Limpopo to investigate how indigenous values have been incorporated or retained on houses built using brick and mortar. The findings show that both traditional rondavel and modern dwellings exist and residents were able to adapt values of indigenous rondavel to modern dwellings, including practising ancestral ceremonies.

Smith ( 2022 ) suggests that the modernisation of the traditional rondavel design into contemporary sensibilities reflects the development of awareness of the diverse heritage that connects South Africa to the rest of the African continent and its people. Thus, the integration and adaptation of indigenous values into modernisation promotes self-definition for many South Africans. Moreover, it encourages a deeper appreciation of the connections between South Africa and the rest of the world. Bianco ( 2022 ) states that this hybrid form of building reflects the evolution of local culture and ways of life so that one can imagine new development aspects entrenched in the culture and environment (Bianco 2022 ). Thus, currently, vernacular architecture can be understood as the foundation of the contemporary architectural type that is rooted in integrating local building traditions (Naude 2010 ; Bianco 2022 ). The current study focuses on the amaXhosa people and intends to understand whether the changing design of traditional rondavels has influenced their utilisation.

The utilisation of rondavels by amaXhosa people

The amaXhosa people are predominantly located in the Eastern Cape province (Nyamende 1994 ; Mokhoathi 2021 ). A rondavel in a Xhosa home ( umzi ) typically exists in a cluster of other structures. Umzi , plural imizi , is a collection of physical, social and organic elements constituting a settlement component known as homestead. It typically comprises several rondavels or huts (the family house, with middle huts reserved for children and visitors as well as a traditional dispensary and consultation), an adjacent garden and a kraal with tools and equipment often used in various ways (Perry 2013 ).

The family house ( indlu enkulu ) is the main hut where everyone meets to socialise and prepare, store and eat food (McAllister 2004 ). It is a space where all rituals take place and people communicate with their ancestors (McAllister 2004 ; Mlisa 2009 ). In the past, following the birth of a child in the family house, children and men were prohibited from using the space (Kobo 2016 ). McAllister ( 2004 ) illustrates how the family house is divided, as shown in Fig. 4 .

This figure was reproduced with permission: Ethnology, Department of Anthropology at the University of Pittsburgh.

The upper part, called entla , is associated with ancestors; an appointed person will commune with the ancestors, and it serves a storage space for meat and beer if there is a ritual planned (McAllister 2004 ; Reeve 2011 ). The right side is the sitting area for men while the left is reserved women. Older people sit next to the door on either side, while the youngest generation often sits next to the upper part of the rondavel (McAllister 2004 ). At the centre is a hearth ( eziko ), where they make fire for cooking (McAllister, 2004 ; Brocious 2021 ). Kobo ( 2016 ) identifies the hearth as a pedagogical space for the girl child to learn food preparation. The way the amaXhosa people utilise the traditional family house can be purported as a gendered space.

A gendered space is “…more attractive for women than for men; men and women use the same space in different ways: some spaces give feelings of comfort and belonging to men, while women feel excluded; in some spaces, women have authority, while other spaces are under male authority” (Fortuijn et al. 2004 : 215). This is a gendered space because of how a spatial order of seating and gender roles in the utilisation of the space is enforced (McAllister 2004 ; Kobo 2016 ).

It should be noted that the number of rondavels in a homestead depends on the family’s needs. In addition to the family house, a rondavel may be reserved as a bedroom for younger family members and to accommodate visitors (Mlisa 2009 ). Moreover, a rondavel may be used by traditional healers for consultations and storing dispensary (umrawule) items. Certain people are often excluded from using such a space. Menstruating women are prohibited from accessing this space while on their cycle because of a belief that they will defile the herbs (Mlisa, 2009 ). The dispensary is only built once a rondavel has been revealed to a potential traditional healer in a dream, and a ritual is performed to officially open the rondavel and the dispensary prior to consultations being held (Mlisa, 2009 ).

Literature is ambiguous as to whether the recorded rondavel uses are performed in traditional or contemporary rondavels and whether the uses are adaptable to current rondavel designs (McAllister 2004 ; Mlisa 2009 ; Perry 2013 ; Kobo 2016 ; Brocious 2021 ). The available literature focuses on understanding traditional rondavel architecture, its utilisation, history and the changes in the design and structure (Schoenauer 2000 ; Steyn 2006 ). Vellinga ( 2006 ) also notes that publications on vernacular architecture are rarely featured and those that are available focus on drawings, forms and material. The impact of changing building designs and structures in traditional space utilisation is inadequately understood. It is against this backdrop that this study uses the concept of habitus to understand whether the changing design and structure of rondavels has influenced the traditional utilisation of rondavel spaces, based on a case study of the Mbhashe Local Municipality in the Eastern Cape province of South Africa.

Pierre Bourdieu, a French sociologist who was concerned with what motivates social action and behaviour (Navarro 2006 ), developed the concept of habitus, which refers to the norms, values, habits, dispositions and behaviour of a particular group. Each society has its own habitus. Habitus can then guide how a particular group feels, thinks, acts and uses the space (Bourdieu et al. 2000 ; Navarro 2006 ). Habitus can be a product of past experiences and practices learned from parents, family experiences, and society (Hong and Zhao 2015 ). It is created and reproduced by the structures and practices of society (Bourdieu et al. 2000 ; Navarro 2006 ). People with similar backgrounds (social class, religion, nationality, ethnicity, education and profession) usually share habitus which shapes how individuals perceive or receive the world. It is not fixed; it changes due to circumstances (Bourdieu et al. 2000 ; Navarro 2006 ). However, when change occurs, some within the group may resist the change while others adapt to a new style of doing things. Often, others combine the traits of new and old habitus. Therefore, the theory seeks to provide an in-depth understanding of how people adapt in a changing world and circumstances resulting to change.

Bourdieu used this concept to study how the Algerian habitus changed during the liberation struggle in the 1950s (Bourdieu et al. 2000 ; Navarro 2006 ). He analysed their norms, values, habits, dispositions and behaviour before and after colonisation. He defined Algerian peasantry as a traditional society which believed in:

the importance of group solidarity;

kinship based on patriarchal and patrilineal relationships;

patriarchal division of labour;

marriage as the primary concern of the family; and

an economy governed by pre-capitalist methods such as

subsistence farming,

products not sold but shared by the community

goods exchanged for social capital (i.e. a neighbour will lend you an ox in exchange for fresh produce).

The economy was governed by strict reciprocity and non-payment. The blacksmith was expected to provide each peasantry with all repairs in exchange for goods and services (Bourdieu et al. 2000 ; Navarro 2006 ). Their habitus was passed from generation to generation. As determined by Bourdieu, habitus changes over time due to circumstances. The change in the Algerian habitus was a result of French colonial imposition which introduced a capitalist economy leading to a decline in agricultural activities and the establishment of factories in urban areas (Bourdieu et al. 2000 ; Navarro 2006 ). Due to this increased urbanisation, people started working for wages, which resulted in the development of social classes (Bourdieu et al. 2000 ; Navarro 2006 ). Subsequently, women were granted access to receiving an education and earning a living. Likewise, society was introduced to the concept of bachelorhood, with marriage being an individual choice. Communal living with neighbours sharing their fresh produce evolved into neighbours selling their produce for cash (Bourdieu et al. 2000 ; Navarro 2006 ). Ultimately, the culture of group solidarity was destroyed, and the focus was on individualism.

Bourdieu argues that change can be adopted or resisted, as evidenced in Algeria (Bourdieu et al. 2000 ; Navarro 2006 ). Certain Algerian norms, values, habits, dispositions and behaviours were influenced by innate traditions of peasantry and colonial imposition (Bourdieu et al. 2000 ; Navarro 2006 ). Most older people resisted the change and continued to be trapped in the old way of life.

This study focuses on the traditional family house rondavel with the users’ social activities derived from the norms, values, habits, dispositions and behaviours of amaXhosa. Premised on the concept of habitus used by Bourdieu et al. ( 2000 ) and Navarro ( 2006 ) in the analysis of Algerian peasantry, this study unpacks the utilisation of the traditional family house rondavel before the introduction of contemporary architecture and design changes. Before the introduction of the contemporary architecture, the traditional family house rondavel was spatially divided based on gender and used for childbirth, communicating with ancestors and hosting rituals, serving and storing food and igniting a fire for warmth (McAllister 2004 ; Kobo 2016 ; Brocious 2021 ). This paper intends to understand whether the changing design and structure of rondavels has influenced its utilisation, using the case of Mbhashe Local Municipality.

Mbhashe local municipality

The Mbhashe Local Municipality extends over a geographic area of over 3200 km² and is situated within the Amathole District Municipality in the Eastern Cape Province, South Africa (Mbhashe Local Municipality IDP, 2016 ; 2023 a). The municipality is named after the Mbhashe River, which tracks between the municipality’s major urban regions of Willowvale (Gatyane), Xhorha and Dutywa, the latter being the administrative centre or municipal headquarters. The municipality has a total population of approximately 240 020 people (Municipalities of South Africa 2023 ), 94% of whom speak the isiXhosa language (Mbhashe Local Municipality IDP, 2016 ; 2023 b). It is a rural region facing various challenges, including poor road infrastructure, high unemployment and inadequate access to essential services such as water and electricity (Mbhashe Local Municipality IDP, 2016 ; 2023 a). It finds significant economic leverage from tourism nodes through coastal, inland and historic or heritage site attractions.

Rondavel structures are prominent in every homestead. Over 66% of households in the municipality are traditional dwellings Footnote 1 , followed by 21 and 5% of households living in brick or concrete block structures and flat blocks, respectively (Mbhashe Local Municipality IDP, 2021 ). However, some households have a modernised rondavel and, more commonly, an octagonal-shape veranda structure, sometimes with an attached garage. Others tend not to have a rondavel at all albeit infrequently. In rural areas, the process of domestic building is not influenced by planning schemes and policies (Oliver 2006 ). Instead, rural architecture is enriched by the surrounding natural environment, local economy and livelihood of villagers (Pirzad and Moghaddam 2023 ). This offers villagers free will to build the type and design of house they desire.

Methodology

Ethical clearance was received from Rhodes University. Purposive sampling was used to select a sample population, which included participants of amaXhosa descent with a rondavel structure in their homesteads and residing within the Mbhashe Local Municipality. Ten participants, aged 24–48 years old, were interviewed; they are referred to as Participants 1 to 10 (P01–P10).

Data was collected using participatory mapping and semi-structured interviews consisting of open-ended questions. The interview schedule was developed with a purpose of obtaining an in-depth understanding of the utilisation of rondavels and changes that occurred over time because of the new architectural style. The interviews were conducted face-to-face at the participants’ residences. The participants were also given a rondavel diagram to illustrate the spatial ordering of how the rondavel family house was utilised in the Mbhashe Local Municipality. The results are presented in Fig. 6 .

Spatial ordering of how the amaXhosa family house rondavel was utilized in the Mbhashe Municipality.

The information from the participants' drawings were then used to create Fig. 6 diagram, which was constructed using ArcMap 10.7.1 software for visualisation of the activities undertaken in the family house. The circle represents a typical rondavel floorplan with a diameter of 6 m (3 m radius). The diameter of the rondavel intersects the doorway and therefore dictates the gendered sides. The points in the diagram do not represent actual geometric values, instead they are ordinal representations of circular living in the AmaXhosa family house. Data was analysed and presented using thematic analysis. The concept of habitus guided the development of the themes presented. The first theme related to the amaXhosa habitus and the utilisation of traditional rondavels in the Mbhashe Local Municipality and the second was the amaXhosa habitus and the changing rondavel design in the Mbhashe Local Municipality

In both themes, specialised quotations to highlight some pertinent statements and demonstrate how the participants make sense of the rondavels and their utilisation, using their exact words.

amaXhosa habitus and the utilisation of traditional rondavel in the Mbhashe municipality

The section of findings only focus on the traditional family house rondavel before the introduction of the contemporary architecture. Adapted from McAllister ( 2004 ), the participants were given a circle to explain the use of each space and its purpose. They also revealed some uses that were not presented in earlier sections. First, the spatial division of the family house based on gender was discussed, followed by how the Mbhashe people utilised the family house. Figure 6 illustrates the spatial division between men (right) and women (left) inside the family house. Women married into the family ( makoti ) are forbidden to access the men’s side. The mud bench, known as soze , is built on the men’s side by the door for seating.

Women sit on the floor on handcrafted mats woven from reeds or grass known as ikhukho . Behind the door on the women’s side is a place for childbirth. The participants also alluded to the statement made by Kobo ( 2016 ) that during the birthing process, children and men are prohibited from using the space. They revealed that there was no cultural significance in giving birth at home. Instead, the inaccessibility of health facilities necessitated home births. Booysen ( 2003 ) argues that, in South African rural areas, women give birth at home because health facilities are located remotely to the homesteads and they do not have the means to access them.

Regarding funeral rites, the deceased’s coffin will arrive at the homestead the day before the funeral and a night vigil – a ceremony to honour the deceased—will be held in the family house. The coffin is usually placed on the women’s side and senior women will gather to sleep next to the coffin until the funeral. An elderly family member will burn impepho (incense) and request the ancestors to welcome the deceased. It is believed that if this ritual is not performed, the deceased will not rest in peace.

In households that use the family house for sleeping, designated spaces will be allocated for men and women. A handcrafted mat is used as a base for the foam mattress on both sides. The seating arrangement in the family house is based on seniority, with younger members of the household placed toward the upper layer, as noted by McAllister ( 2004 ). The participants further explained that seniority was not based on age: married women were regarded as senior and women who were not related by blood or matrimony would occupy the upper end of the women’s side. Men’s seating arrangements depend on when one was initiated, with the youngest (the last to go to the bush) towards the upper layer.

McAllister ( 2004 ) and Reeve ( 2011 ) reveal that an appointed person will commune with the ancestors, and store meat and beer in the upper part of the rondavel if there is a ritual. Their findings concur with how the Mbhashe people utilise the space, further indicating that the upper layer is divided into A and B, as shown in Fig. 6 . On the right (men’s side) is where slaughtered meat and beer is stored. It is the responsibility of the men to serve both the meat and beer; hence, it is located on their side. Section B in Fig. 6 is a space in the uppermost end of the rondavel on the women’s side. It contains domestic essentials such as a table and cupboard, crockery, and cutlery and ilitye lokuguba , which is a flat rock which is used to grind food.

In the centre of the family house is a hearth. Kobo ( 2016 ) argues that this is where women are taught to prepare food. The findings of this study also reveal that men also use the space to roast corn. So, there are no gender-based restrictions on the use of this space. The centre also has a pole called intsika , which supports the roof structure. The door is positioned in the lower part of the family house. Section C, illustrated in Fig. 6 , is where the spear ( umkhonto) is kept by sticking it on the roof above the doorway on the men’s side. The spear is used for the slaughter of traditional animals if there is a ritual or ceremony. The spear is believed to obstruct lightning during a storm and is placed in the doorway.

The participants also utilised the rondavel for interacting with each other and the ancestors. Interaction takes place through song and dance during ceremonies. People also interact through spoken word to communicate with or appease ancestors, to socialize with each other by telling stories of love, horror, fiction, and the past, and to play games. The study’s participants expressed clearly how the family house is used which they learned from growing up in rural areas and passed from generation to generation. They have the duty to continue passing this information to the younger members of the family.

amaXhosa habitus and the changing rondavel design in the Mbhashe local municipality

People in the rural areas of the Mbhashe Local Municipality were inclined to architectural change and desire contemporary architecture and luxury, including those who did not currently own it. The contemporary rondavel design was considered progressive, cognisant of the times and, for that matter, the contemporary way of life to which there was a strong inclination to conform: “I too [wish to have a modern house] because these are the houses that are built nowadays, and they make the home beautiful” (P 01).

Notwithstanding, there was a strong consensus to preserve conventional ways of using space and adapt to the contemporary design, including the structure and shape (multi-room), the material used (no longer a thatched roof or mud walls), or hard surfaces (tiles/concrete). The respondents preferred contemporary structures because of their aesthetic and convenience: “…contemporary houses have better aesthetical value, spacious and are functional (e.g., energy consumption, natural lighting)” ( P 09).

Other uses were not adopted in the contemporary house design such as utilising the family house for childbirth because modern women mostly give birth in hospitals and clinics. Statistics South Africa ( 2020 ) revealed that the number of home deliveries has decreased from 14% in 1998 to 4% in 2016 while health facility deliveries have increased from 83.4% in 1998 to 96.7% in 2016 (Statistics South Africa 2020 ). Both 1998 and 2016 home deliveries statistics are indicative of the national level (Statistics South Africa 2020 ).

Placing the deceased’s coffin in the upper part of the family house (section B in Fig. 6 ) was adopted in contemporary rondavel utilisation until the Covid-19 pandemic when people became sceptical of disease transmission. Before the pandemic, the deceased’s body would arrive at home a day before burial, and people would gather for a final ceremony the night before the funeral (night vigil) inside the family house to honour the deceased (Bambalele 2020 ). A South African Covid-19 restriction prohibited corpses being sent home prior to the funeral and the hosting of night vigils (Bambalele 2020 ). This practice has continued since Covid-19 restrictions were relaxed, while others have stopped. However, once the deceased’s coffin arrives on the funeral day, it is taken to the upper part of the family house and a ritual will still be performed where incense is burnt and a request is made to the ancestors to welcome the deceased. Therefore, the cultural significance of the whole process does not rest with the placement of the deceased’s body a day before the funeral but the performance of the ritual.

The presence of mud benches on the men’s side no longer exists. Although the traditional rondavel structure is diminishing in the physical environment, modernisation has certainly swayed people’s sense of feeling, thinking, acting and their use of space. Admittedly, modernisation has not entirely appropriated the Xhosa people’s habitus. Some people were uninterested in adapting to some elements of the contemporary rondavel and house design: “A traditional rondavel must be present in a home. You can make fire, but it is difficult to do that on floor tiles. Still, you perform customs in traditional rondavel” (P 03).

These people continue to use traditional rondavels for the above purposes while also adapting the contemporary rondavel or house design for other uses such as sleeping, unless there is a ceremony when there is no space: “ People do not want to sleep on the floor in the rondavel, and there is no privacy and tile, or cemented floor is cold” (P 04).

While other participants preferred to continue performing traditional ceremonies and communicating with ancestors in the traditional rondavel structure, there were respondents who were open to communicating with ancestors and interacting with the living, and divide space based on gender in the contemporary rondavel – as indicated in Fig. 6 . The cultural strongholds continued to be practiced regardless of the house structure. Therefore, in the absence of a traditional rondavel structure in a homestead, any other house design such as butterfly or flat-roof corner houses can be used for traditional ceremonies: “any house structure can be used as a rondavel; it does not change the culture. It is the same” (P01).

Regarding food preparation, serving and storage, some people used the contemporary rondavel with slight changes for cooking. For example, food is prepared in the family house’s upper part (B section in Fig. 6 ) using a gas or electric stove instead of a hearth at the centre. Others will prepare food and store it in the kitchen of the main house, but people will be served in the contemporary rondavel.

This paper used the concept of habitus to understand whether the changing design and structure of rondavels has influenced its utilisation. Habitus refers to the norms, values, habits, dispositions and behaviours of a particular group, which can then guide how they feel, think, act, and use the space. Habitus can be a product of past experiences and practices learned from parents, family experiences, and society (Hong and Zhao 2015 ). It is created and reproduced by structures and practices of society; it is not fixed and changes over time due to particular circumstances (Bourdieu et al. 2000 ; Navarro 2006 ). The study discussed the amaXhosa people’s habitus on the utilisation of the traditional family house rondavel and how it has been influenced by the introduction of contemporary architectural designs. It is noted that architectural change brought by society does not change cultural norms, values, habits, dispositions and behaviours attached to rondavels but results in finding ways to accommodate and preserve its utilisation in new architectural developments and selectively choosing ideas to be transmitted to the contemporary house design. The cultural norms, values, habits, dispositions, and behaviours attached to rondavels have also been influenced by advancements in health and medical innovation, as well as Covid-19.

The findings revealed the habitus of the amaXhosa people at the Mbhashe Local Municipality. The utilisation of the traditional family house rondavel includes childbirth, placement of the deceased’s coffin, sleeping, seating, food preparation, serving and storage, keeping the spear, hosting ceremonies, communicating with ancestors, and interacting with the living. The amaXhosa habitus is acquired by growing up in the Xhosa society, being taught by parents, and observing how things are done, which has been passed down from generation to generation. The influence of contemporary architecture brought changes in the construction of rondavel.

Home births are no longer practised because of advancements in health and medicine. The placement of the deceased’s coffin in the upper part of the rondavel a day prior to the funeral has been adopted in the use of a contemporary rondavel; however, it is no longer prevalent because of the Covid-19 restrictions. However, on the day of the funeral, the deceased’s coffin is placed in the upper part of the rondavel for a shorter period and a ritual burning incense and asking the ancestors to welcome the deceased is performed because it is a critical cultural practice.

People also do not opt to sleep on the floor unless there is a ceremony. The preparation of food, its serving and storage differs in that there is no hearth in the new contemporary house; so food is prepared in the main house or the upper part of the rondavel. The gendered division of space, hosting ceremonies, communicating and interacting with ancestors has been adopted in contemporary houses too. However, some still prefer to host ceremonies and communicate with the ancestors in traditional rondavels instead.

People have not resisted new architectural designs or changing cultural norms, values, habits, dispositions and behaviours but have found ways to adapt. Certain old dispositions are adaptable to contemporary structures. Also, a study conducted by Moremoholo ( 2021 ) reveals that some indigenous values such as practising ancestral ceremonies can be incorporated or retained in modern house structure. However, some people are not interested in adapting elements to the contemporary rondavel. They would rather have two structures – the current rondavel design and a traditional rondavel to be utilised for uses that cannot be adapted to the contemporary rondavel. The presence of traditional rondavel in modern times is also witnessed even in Nigeria (Onyejegbu et al. 2023 ).

Some cultural norms, values, old habits, dispositions, and behaviours of utilising traditional rondavels were not adapted to the contemporary rondavel because of health and medical innovations such as childbirth and placing the deceased’s coffin in the rondavel. Clearly, some amaXhosa cultural practices are modified but not completely forgotten.

Future studies can focus on profiling architectural designs found in the Mbhashe Local Municipality and investigate their origins and influencing factors. Others could also focus on rondavels utilised by traditional healers to understand how they have been impacted by architectural changes to space utilisation. It will be also interesting to understand why people still opt for traditional rondavels despite the existence of beautiful modern buildings.

Interview with case study, what to expect?

I got an invitation to a second interview for a Data Analyst position. For the interview they want me to present a case study for which they have provided a csv, my question is what is expected of me?

The csv is a customer satisfaction survey with columns regarding: "How easy was it to handle the matter?", "Did you receive the help you expected?", "How satisfied are you with the recieved service?" and "How likely are you to recommend us to someone you know?"

During the first interview they discussed data visualisation alot so I feel like that is at least expected of me. Any general points of directions what visualisation and analysis that is probably expected would help alot since this is the first time I've gotten this far in the interviewing process.
