Nailing An Analytics Interview Case Study: 10 Practical Strategies

10 practical tips/strategies I extracted myself when doing analytics case study as part of job interview process.

Jan 16, 2024 . 11 min read

Picture yourself aiming for coveted roles in the data realm, such as Senior Analytics Manager, Head of BI, Director of Analytics, and so on. If you aspire to leadership positions, you should be well versed in case studies - it is rigueur du jour in analytics interviews.

But what exactly makes a case study so vital? It's your stage to showcase how well you grasp a company's heartbeat: its business model. It's where your problem-solving, technical savvy, and ability to communicate like a seasoned team member come under the spotlight.

In this article, I will show you 10 strategies for acing your analytics interview case study.

To supplement this, I'm going to draw from my own real-life experiences. Specifically, I’ll be citing examples from my own experience interviewing for a tech giant in Singapore.

I’ve gone through my fair share of case studies and interviews with tech companies as a data professional with over a decade of experience. While I am by no means an expert, I hope these insights will inspire you to develop a personalized, winning approach to your next interview case study.

For this case study, I was asked to propose a method for mapping a large data set of Vietnamese addresses to geo coordinates in a cost-efficient and scalable manner.

• Input: A set of Vietnamese addresses in text form
• Output: For each address, their corresponding geo coordinates

I was also supplied with a dataset of 10,000+ Vietnamese addresses. But I can spare you the details here.

Above: Example of a Vietnamese address that needs to be mapped to a set of geocoordinates.

That’s the essence of the problem statement. Now let’s get into the 10 strategies/principles that I operate by.

Strategy 1: Show that you understand the context

Your first priority is to demonstrate that you understand the company’ business goals, its team dynamics, and the specific challenge at hand.

Above: My presentation begins with these slides, titled “The Challenge”, in which I distilled the problem into a clear, succinct statement, to show that I grasped the essence of the issue.

How I applied this strategy in my case study:

To prepare myself for this case study, I watched several videos on the company’s official YouTube channel so that I understood the company’s ambition of expanding into the Vietnamese market.

Next, I downloaded the product and tested it as a user, so that I’d get a firsthand perspective of how this data set would tie to the company’s product development framework.

Last but not least, I looked up the LinkedIn profiles of everyone on the interview panel to get a sense of their personalities and professional history. As the lead interviewer had a long history of working as a management consultant, I decided to craft my presentation as a set of PowerPoint slides, based on the assumption that this is the format that would be comfortable for a seasoned consultant.

This strategy wasn't just about the technicalities of the case study. It was about showing that I could fit into their world, understand their challenges, and speak their language.

Strategy 2: State your assumptions

Regardless of the problem you’ve been tasked to solve, you’re likely to have incomplete information, and will need to make a few reasonable assumptions - be it assumptions about the team’s intentions, the parameters of the problem, the desired solution, and so on.

This is equally true in the day-to-day reality of any professional environment; decision-making is rarely black and white. A good leader, however, is able to anticipate knowledge gaps and exercise good judgment in the face of it. The case study is your opportunity to showcase these crucial skills.

Above: The first of a few slides in which I stated the assumptions I made before tackling the problem.

In my case study, I listed assumptions that I’d made regarding the technical details of the problem, the long-term applicability of a desired solution, as well as the expected timeline for solving the problem.

None of these factors were addressed in my assignment. However, given that they’d dramatically restrict the possibilities of a viable solution, I felt that it would be wise to sketch out these areas of uncertainty. By doing so, I was able to apply reasonable conjectures and zoom in on a practical solution.

Strategy 3: Explain your thought process

This is an important point that you must remember: Case studies are less about pinpointing a specific solution, and more about unveiling the narrative of your problem-solving style. Interviewers are keen to dive into your thought process, to see how you navigate a maze of challenges, rather than just where you end up.

Above: The slide in which I not only stated my proposed solution (using HERE Location Services), but also the thought processes that guided my approach.

In my case study, I ultimately proposed using HERE Location Services for mapping Vietnamese addresses to geocoordinates.

How did I arrive at this solution? It began with a careful weighing of goals, like balancing accuracy against cost-efficiency, and taking constraints (such as budgets) into account.

Next, I conducted a comparative analysis between HERE Location Services vs. other possibilities. I highlighted the superior quality of HERE Location Services’s data sources compared to most of its competitors, as well as its attractive pricing model, thereby presenting a compelling case for my choice.

Moreover, I leveraged my past experiences, drawing parallels between this case study and similar projects I had undertaken previously. On another slide, I detailed how these experiences provided a rich backdrop to my current approach, adding depth and credibility to my solution.

Strategy 4: Validate your solution

As you lay out a solution, it is important that it doesn’t just sound good on paper - it needs to stand up to real-world scrutiny and application.

A good solution is one that meets redefined objectives and creates value, be it in terms of cost-efficiency, time savings, improved health outcomes, increased customer satisfaction, or any other metric that’s relevant to the company’s product model.

Try to answer this question: If your approach is a good one, how would its success be measured?

Above: The slide in which I propose a method for validating my own proposed solution, i.e. benchmarking HERE Location Services against Google Maps.

In my case study, I proposed using Google Maps Geocoding as the industry gold standard, and the following as a criteria for success: If X service is a reliable solution, then it should be able to mirror Google Maps Geocoding’s results with only a small loss in accuracy.

Next, I created a trial account on HERE Location services and tested a small sample data set of Vietnamese addresses, and demonstrated that it was, indeed, able to replicate Google Maps Geocoding reliably. In doing so, I didn’t just propose a solution, I also proved its viability in the real world.

Strategy 5: Anticipate, adapt, and articulate

The climax of your case study is not how you present your solution, but how you defend it from a barrage of questions from your interviewers. To navigate this smoothly, you can take a pre-emptive approach by anticipating these questions and integrating the answers in your presentation, showcasing not just your solution’s strength, but your foresight as well.

Above: I anticipated several scenarios in which my solution might evolve or require scaling the future. For instance, I anticipated that the company may want to expand into new markets beyond Vietnam, and replicate the same geo-mapping exercise in new markets.

So, how did I turn this anticipation into an asset during my case study? I prepared myself for a range of questions, such as:

• What are the potential hiccups and roadblocks of your solution?
• Let’s say that the business goal / scope of the problem shifted unexpectedly, how would you tailor your plans?
• What kind of support would you need from us to implement your solution?

As it turned out, many of these questions did come up during the interview.

But let's be real – no matter how well you prepare, there will always be curveballs. Whenever the panel threw a question I hadn’t foreseen, I stayed grounded. I would respond, "In a real-world scenario, I'd take some time to consult with experts like ABC and delve into research on topics like XYZ to formulate a well-rounded hypothesis."

This approach served a dual purpose. It showed that I could think on my feet and, more importantly, that I understood the value of thorough research and collaboration in tackling unforeseen challenges. This way, even without an immediate answer, I demonstrated a methodical and strategic approach to problem-solving."

Strategy 6: Add depth to your presentation with an appendix

As you draw your presentation to a close, consider the impact of an appendix. This section can be a treasure trove of supplementary details, showcasing the depth and rigor of your preparation. Many interviewers will be impressed by this extra effort, seeing it as a testament to your thoroughness and commitment to providing a comprehensive, informative deck.

Above: I added slides in which I explained how I approached my case study.

In my case study, I decided to enrich my presentation with a detailed appendix. Here’s what I included:

• A Peek Behind the Curtain: I provided snapshots on how I prepared for the case study, including people from whom I solicited feedback, tools and resources I’d used, etc.
• Technical Documentation: I provided the actual Python scripts and calculations that I used to answer technical questions, to serve as concrete evidence of my analytical capabilities.
• Notes On the Complexity of Vietnamese Addresses: I dedicated a section to elaborate on the complexities of mapping Vietnamese addresses. This wasn't just about showing the problem; it was about highlighting the nuanced understanding I had developed regarding this specific challenge.

Strategy 7: Elevate your presentation with good visual design

While it's the content that truly matters, never underestimate the power of a visually captivating presentation. It's the icing on the cake that can set you apart from other candidates.

Above: I like to enhance my presentation with beautiful images and photos from royalty-free sources such as Unsplash.

The following are some of the stylistic practices that I personally use in almost all of my interview presentations:

• Embrace the Company’s Visual Identity: I love to align my presentation with the company's branding. Using their official fonts and color palette not only shows that I've done my homework but also helps my presentation resonate with the company's ethos.
• Legibility is Key : Dense paragraphs are a no-go. I keep my text concise, aiming for a maximum of 2-3 sentences per paragraph. If the text starts to get lengthy, I break it up over multiple slides. It's all about making the content digestible and easy on the eyes.
• Consistency is Crucia l: From font sizes to text box positions and paragraph styles, I ensure every visual element tells a unified story. This consistency underscores the narrative of my presentation, making it more compelling and professional.
• Strategic Use of Images : To break the monotony of text, I sprinkle in high-resolution, royalty-free images from sources like Unsplash. These images aren't just fillers; they're carefully selected to enhance the narrative and add a visual punch.
• Smart URL Customization : When I use browser-based presentation tools like Google Slides or Miro, I create custom URLs for easy access. For instance, transforming a lengthy link into something sleek like www.tinyurl.com/holisticscasestudy not only makes it more memorable but also adds a layer of professionalism.

Through these subtle yet impactful design choices, I aim to convey meticulousness, consistency, and a work ethic that values thoughtfulness and rigor.

Strategy 8: Refine and rehearse

After drafting your presentation, it's time to elevate it from good to great:

Seek insightful feedback: Share a duplicate of your presentation with trusted friends or mentors. Their fresh perspectives can provide invaluable insights on how to enhance your presentation.

Master the delivery: Rehearse, rehearse, and rehearse some more. Whether it's with a partner or recording yourself, this step is crucial. You've invested hours in the content; now, focus on how you deliver it. Aim for clarity, structure, and a compelling narrative that keeps your audience hooked.

One more tip: Always start with a brief introduction about yourself; don’t assume that all your interviewers know who you are. It helps to set the stage before you dive into your presentation.

Strategy 9: Mind the clock

On the big day, keep an eye on the clock. Even with the most meticulous preparation, you might face unexpected technical hiccups and delays. A good rule of thumb is to aim to complete your presentation within 80% of the allotted time. For instance, if you have 30 minutes, try wrapping up around the 24-25 minute mark.

During the Q&A session, if given the option, always choose to address questions at the end. This keeps your presentation flow uninterrupted and ensures that your audience hears your complete thoughts before they jump into questions.

Strategy 10: Treat the interview as a two-way street

Remember, the case study is as much about you evaluating the company as it is about them evaluating you. Use this opportunity to ask insightful questions about the team, upcoming projects, and the rationale behind the case study. This dialogue will give you a clear picture of the company's values and work culture.

Post-interview reflections are just as crucial. Ask yourself: Can you see yourself thriving in this environment?

Interviewers from an organization with good work culture will always ask questions in a respectful manner, and provide constructive feedback. The nature of your interactions can provide valuable insight into the kind of support, mentorship, and collaboration you can expect if you join the company.

Full disclosure: Despite my efforts, I didn’t land the job for which I crafted the attached case study. Nevertheless, I still had fun and learned something new in the process of doing research. Case studies, while demanding, have always been the highlight of my interviews.

Regardless of the outcome, treat every case study as a learning experience - as a way to learn more about different companies, product problems, and business strategies, and get better at interviewing. The hours that you spend chipping away at challenges like these are a vital part of your career development. Maybe the real treasure is the insights we gain along the way. ;)

Capital One Case Interview (Questions, Process, Prep)

Today we're going to cover everything you need to prepare for your Capital One case interview.

If you're a business analyst, senior data analyst or strategy analyst, and you're not used to case interviews, they can be challenging. That's why we've put together the ultimate guide to the Capital One analyst interview to maximise your chances of success.

Here's an overview of what we'll cover:

• Assessment tests
• Case interviews
• Product questions
• Behavioural questions
• Preparation tips

NB: If you're a software engineer interviewing at Capital One, check out our engineering interview guides .

1. Capital One: doing things differently

Capital One is unique. As of the time of this article, it's the 13th largest bank ($450bn in assets)  in the United States, behind firms like  Goldman Sachs , JP Morgan , and Morgan Stanley , despite being founded as a single-business  bank in 1994. The business was initially only focused on credit cards but now include the following 3 verticals:

• Credit Cards
• Consumer Banking
• Commercial Banking

The company's success has been driven largely by its clever use of data . They've developed sophisticated strategies for identifying and directly marketing to profitable customers. This has created a competitive advantage vs. traditional banks, which have historically focused on broad (rather than targeted) marketing.

Capital One also has their own  strategy group , which essentially serves as an internal consulting firm.

Although Capital One is a top player in the banking industry, their unusual history and technology focus, has created a unique culture. It has more of a "tech firm" feel, than you'd expect from a giant financial institution. Another notable area where Capital One is different from their peers, is in their interview process.

2. Capital One interview process

The type of work (and the nature of the interview) you can expect at Capital One varies across group and role. They hire for roles ranging from call center reps, to software engineers and business analysts.

This guide is primarily written for business analyst candidates, but most of what we say here is applicable for anyone with a case interview at Capital One, including senior data anlaysts and strategy analysts.

The application process includes 4 main stages:

• Resume & cover letter submission
• Pre-interview online assessment tests
• First-round interview

Power Day of 3-5 interviews

Let's take a closer look at each step in the Capital One interview process.

2.1 Resume & cover letter submission

First, recruiters will look at your resume and assess if your experience matches the open position. This is the most competitive step in the process—we’ve found that 90% of candidates don’t make it past this stage.

You can use  this free resume guide  and this  free cover letter guide  to help tailor your application to the position you’re targeting. 

And if you’re looking for expert feedback, you can also get input from our  team of  expert recruiters , who will  cover what achievements to focus on (or ignore), how to get more impact from your bullet points, and more.

2.2 Capital One online assessment tests

After the initial application, you'll face the   online assessment tests.

For the business analyst position, the BA quantitative assessment usually consists of 11 questions that aim to assess basic analytical skills. You'll be given a data set and you'll need to use a spreadsheet to solve mathematical and analytical problems.

Example Capital One online assessment question

• Ali and Sophie are budding musicians who have been playing Thursday night shows at a local live music venue. The venue told them that over the course of the last four weeks, they’ve had 900 tickets sold for their shows. They are curious to see how many people are repeat fans, coming to more than one show. The venue’s recent customer survey says that 60% of fans have come once, 30% have come twice, 6% have come three times, and 4% have come four times. How many unique people have seen an Ali and Sophie show during this time period?

2.3 First round mini case interview

If you pass the online assessment, you make it to the first round 'mini case interview', which will be conducted via phone or video call. Be ready to hit the ground running in this interview, don't expect much "getting to know you" discussion because they usually get straight to the case. This interview will normally last 30 minutes.

2.4 Final round Power Day

The final round, often referred to as a "Power Day" or a "Super Day", is  a series of 3-5 back-to-back interviews .

For the role of business analyst, you can expect two case interviews and one product interview, with behavioral questions thrown in at the start of each interview.

If you're interviewing for a more technical role, such as senior data analyst, you will face a technical interview such as coding or a data challenge, one case interview and one behavioral interview.

Now you know the interview process, let's go deeper into what questions you can expect to face.

3. Capital One interview questions

In this section we'll take a look at the type of questions you can expect to face in your Capital One interview. We'll start with the most important, and the most challenging: case interview questions.

3.1 Capital one case interviews

Case interviews are the most important part of the Capital One interview process. The company has published a video tutorial, which shows the style of their case interviews.

We've embedded it for your reference below. It's a great resource, but it's pretty long (about 20 minutes), so we've also summarised the key take-aways and added some additional commentary below.

Capital One case interviews include 3 sections:

• Business situation and framework
• Quantitative question
• Recommendation

Each section of the case interview has particular things you'll need to prepare for. Let's look at each one in-depth.

A. Business situation and framework

The first several minutes of the interview will cover the business scenario and case framework. This typically begins with the recruiter providing a brief statement about the business or industry where you'll focus for the case. In the sample case (in the video), you're the CEO of Ice Cream Corporation. 

Typically, the recruiter will end their opening statement with a broad question. For example: "What are the key factors you would consider when developing a strategy to grow profits for Ice Cream Corporation?" For this stage of the interview, you should have two objectives.

First, you should ask clarification questions to make sure that you understand the situation correctly. For instance, in the video above the first candidate asks exactly what role the CEO has with regards to "pricing" and to "sales". Many candidates skip that initial step, but it's actually essential because it will help you put together a more relevant framework.

Second, once you fully understand the situation and question the interviewer is asking you, you should put a simple case framework together to answer the interviewer's question. The objective of this framework is to identify and communicate key areas that you will consider to answer the interviewer's main question. For instance, the candidates in the video mention areas including pricing, number of markets, number of competitors, their size, etc.

If you're familiar with the different types of case interviews, you'll notice that Capital One uses the interviewer-led approach. This is similar to the method used by McKinsey in their application process .

That said, we still recommend that you try and drive the case forward yourself to a certain extent, by communicating the implications of your answer with the interviewer. This will show them that you're able to think a few steps ahead and take an active approach to problem-solving.

B. Quantitative question

The second stage of the interview is heavily focused on maths skills. The recruiter will provide you with some data, and ask you to perform calculations.

In the sample case, you're asked to calculate total monthly profit for Ice Cream Corporation, given the following data:

• Price per carton = $5
• Cost per carton = $1
• Demand = 100 cartons/month

It's important to ask questions at this stage, as the recruiter may have additional data which they have not yet provided. The video shows a great example of this, when the candidate asks how much of the cost is variable vs. fixed cost. 

• Variable cost per carton = $1
• Fixed cost per carton = $0

At this point, the calculation is straight-forward.

• ($5-$1) X 100 cartons = $400 profit

Make sure you talk through your logic, to show the recruiter your problem-solving skills. This will also help them to steer you back on track, if you've misheard any of the data.

Don't expect all of the calculations in your interview to be this simple. There are 2 additional examples provided in the video, which include elasticity of demand and break even calculations. These require a little extra work, but your approach will be the same:

• Understand the data provided
• Ask for more information when necessary
• Lay out your approach
• Perform the calculations

In our experience, the best candidates brush up ahead of their interview, so they can   have confidence in their maths skills . If you do the same, this will give you a polished reaction during interviews, which recruiters will notice. Compared with the case interviews used at consulting firms, the case interviews at Capital One tend to have a greater focus on quantitative questions. So you should expect to spend more time on these types of quant problems during your interview, and less time on other areas, like creative brainstorming.

C. Recommendation

In the final stage of the interview, you'll be expected to make and defend a recommendation. To form your recommendation, draw on the calculations from the previous stage (e.g. the results of the break-even analysis). Consider the numbers, use your intuition, and make a decision . 

For example, this might be your conclusion: "since frozen ice cream is a non-perishable, I think it would be reasonable to expect most of the additional sales from a promotion, to come from stock-up behavior. I'd recommend looking for other opportunities to increase sales."

The specific strategy you suggest, is less important than your logic and ability to defend it . Expect the recruiter to question your approach. For a recommendation like this, they may ask you to explain how you would go about identifying other opportunities.

Additional tips for your Capital One case interview:

• Don't be surprised if you're given a case from outside the finance industry
• Take notes on the information provided by the recruiter.
• Ask for a minute to organize your thoughts when needed.
• Talk through your thought process, show your work as you do it.
• If you don't understand a topic, ask the interviewer for clarification.
• Call out important assumptions.
• Notice directional cues, as the recruiter may want to steer the conversation.
• You're usually allowed a calculator, so bring one that's easy to use

3.2 Capital One behavioural and fit interview questions

In addition to case interviews, Capital One also uses behavioural questions/interviews, like most companies do. While you may not get a whole interview devoted specifically to behavioral questions, you can expect to face them at the start of your case and product interviews.

Behavioural interview questions asked at Capital One fall into two main categories:

• Fit questions. These are generic questions such as “Why financial services?” or “ Why Capital One? ”.
• Personal Experience Interview (PEI) questions. These are questions such as “Tell me about a time when you lead a team through a difficult situation.” Or “Tell me about a time where you had to manage a team conflict”

We've written extensively about   fit / PEI questions   in another guide. But in summary here are the top 5 fit and PEI questions you should prepare for at Capital One, or other firms.

Top 5 fit questions:

• Why Capital One?
• Why financial services?
• Walk me through your resume
• Tell me about something not on your resume
• Tell me about your greatest accomplishment

Top 5 PEI questions. Tell me about a time when ...

• You failed at work
• You worked in a team and had to manage a conflict
• You had a disagreement with a colleague / boss
• You had to change someone's / a group's mind
• You led a team through a difficult situation

Capital One is known to favor the STAR method when it comes to answering behavioral questions. So, for your interview, plan to answer behavioural questions using the following format:

• S - Situation

This approach will help you to answer each question in a clear, and methodical way, which are great qualities to demonstrate when interviewing with Capital One. 

3.2.1 "Why Capital One?" interview question

You're almost guaranteed to be asked this question, so let's dive a bit deeper into how you should answer it. Here are 3 ways to make your answer stand out:

Name-drop: Before the interview, make an effort to meet with or call one or more current employees of the firm. Ask them what it’s like working there, why they chose Capital One and what is unique about it. This will give you good, specific talking points for your answer, and mentioning their names shows the interviewer that you’ve put in effort to get to know the company.

Be specific. Test out your answer by swapping another bank’s name with the one you’ve got in mind. If your answer could also apply to this other bank, then you need to fine tune it.

Keep up with recent activity : Being aware of the latest deals and developments in the department you’re applying to will give you an idea of what kind of projects you’ll get to work on, and whether they sound interesting to you. Bringing them up in the interview will show the interviewer that you’ve done your research and stay up to date on market news.

Example answer: "Why do you want to work at Capital One?"

“I want to work at Capital One for three main reasons. First, I want to work in a very data-driven environment and to have access to a vast amount of data when working strategically. I've been really impressed with Capital One's pioneering use of data and machine learning in the banking sector, which has helped it gain market share across its verticals.

Second, I've also been impressed with Capital One's strategy regarding a banking-as-a-service model and embedded finance. I saw an interview with Richard Fairbank (CEO) talking about how all banks needed to collaborate with fintech apps to provide instantaneous results for customers, rather than working in silos, and I thought he articulated a really strong vision.

And finally, I’ve had a few conversations with Seth White and Tamara Grey, associates in the McLean office, both of whom gave me a great impression of the firm as a whole. Seth in particular encouraged me to apply to the Travel team, as we share a similar educational background, and he was complimentary of the opportunities he’s been given to succeed."

See more details on how to answer the "Why this company?" interview question .

3.3 Product questions

If you're interviewing for a business analyst role, one of your Power Day interviews will be a product interview. Compared to the very quantitative case interviews, the product interview is a lot more qualitative and you'll need to think more creatively.

In almost all the interview reports we've seen over the last year or so, the candidate was asked to improve a product in some way. We recommend you read our article on How to answer product improvement questions to help you structure your response.

Example Capital One product questions from business analyst candidates:

• Describe 12 uses for an alarm clock
• How would you redesign an alarm clock?
• What is the customer base for this product?
• Describe 10 ways to improve an umbrella
• How would you improve this water bottle?
• What's your favorite product and how would you improve it?

4. How do I prepare for a Capital One case interview?

Here's how we recommend you prepare for your Capital One case interview. First, use Capital One case studies to research the company. Second, become really confident at maths. Then, learn a consistent method to approach case interview problems. Fourth, practise a lot and learn from your mistakes. And finally, do mock interviews to hone your case interview technique.

4.1 Use Capital One case study examples for research

Case interviews require no prior knowledge. However, you can bet that overall your interviews at Capital One will go a lot better if you go in having done some research on the company and the wider financial industry.

Capital One shares some case studies on its website, which are well worth looking over. Also take a look at some of the articles on Capital One's insights center . Elsewhere in the media, we liked this piece on how Capital One uses data to get an advantage .

If you're coming from a finance background, you may already have a good knowledge of Capital One's place in the sector. If not, check out Investopedia for a brief summary.

4.2 Become really confident at maths

You don't have to have a perfect GPA or GMAT score to succeed at case interview maths. And in any case, during your Capital One interviews, you will be allowed to use a calculator. That said, it will help if you're confident performing mental maths quickly and accurately.

In order to do this, it’s essential to know the formulas for common metrics, like return on investment or breakeven point. And it’s also helpful to know a few maths shortcuts to help you solve problems more quickly. To learn more about these topics, check out our free guide to case interview maths . 

In our experience, the most successful applicants start their interview preparation by practising maths skills, so make sure you prioritise this step.

4.3 Develop a consistent method to crack cases

One of the biggest challenges of interviewing with Capital One  is solving cases that you’ve never seen before. Each case can be difficult, and you’ll have to perform well across multiple case interviews in order to get an offer.

As a result, it’s critical for you to have a consistent approach for solving cases. Capital One  uses interviewer-led case interviews, which can be broken down into the following types of questions:

• Framework development
• Quant question – Data provided
• Creativity question

If you can crack each type of question (within a case), then you can crack the overall case.

Use this list of example case interviews to practice with. The companies listed here are consulting companies rather than banks, but doesn't matter as case interviews use examples from all sorts of industries, not just the one you're interviewing for.

4.4 Learn from every mistake you make

During case interview preparation, the quality of your preparation is just as important as the quantity of time that you dedicate. It's better to do 20 cases thoughtfully than to rush through 40 cases. 

We recommend that you keep a notebook where you record improvement opportunities and specific things you did well for each case. 

The notebook and self-evaluation will help you to be more strategic (and efficient) with your preparation. It's also a good idea to go back and re-do old cases. For example, after you have done case #20, you could go back to case #1, to make sure you are not repeating the same mistakes.

The minimum preparation time required to succeed in case interviews is probably around 30 hours. However, if you don't prepare thoughtfully, it may take much longer. So take notes, be strategic, and keep practising!

4.5 Do mock interviews

How you solve each case is important, but your interviewers will also be evaluating how you COMMUNICATE your answers. It's important to speak in a structured way that makes it easy to clearly understand your points.

The best way to hone your communication skills is to practise interviewing out loud, and you can do that in three main ways:

• Interview yourself (out loud)
• Practise interviewing with friends or family
• Practise interviewing with ex-interviewers

Practising by yourself is a great way to get started, and can help you get more comfortable with the flow of a case interview. However, this type of practice won’t prepare you for realistic interview conditions. 

After getting some practice on your own, you should find someone who can do a mock interview with you, like a friend or family member.

We’d also recommend that you practise 1-1 with ex-interviewers from top consulting firms . This is the best way to replicate the conditions of a real case interview, and to get feedback from someone who understands the process extremely well.

• 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.

Top 100+ Data Analyst Interview Questions for 2024

Introduction.

Over ten years ago, a data analyst interview was very simple. All you needed to know to say was two things:

• “Yes, I know Excel!”
• “I’m a great communicator.”

Nowadays, the  role of a data analyst  has changed. Not only have salaries shot up, but data analysts are more in-demand than ever before due to their insight and analytical skillset.

Most data analyst jobs at tech companies require a strong technical skillset combined with good judgment. In this guide, we’ll break down the interview process and the most common data analyst interview questions.

Data Analyst Interview Guide

Technical interviews for data analyst roles are typically multi-stage interviews. They start with initial screens designed to weed out candidates, and quickly progress to more technically demanding screens. To  prepare for a data analyst interview , practice questions in each of these category.

Here’s a typical breakdown of the data analyst interview process:

1. Initial Phone Screen

Initial screens are generally calls with recruiters. These screens assess your experience, your interests/specializations, and salary expectations. In some cases, you may be asked  basic SQL questions  or a simple  scenario-based case question .

Sample question:  Tell us about a challenging project you have worked on. What were some of the obstacles you had to overcome?

2. Technical Interview

The technical screen assesses your technical skills. In many cases, SQL is a primary focus. SQL questions range from basic definitions, to writing intermediate-to-advanced queries. Depending on the job function, you may be asked technical questions about Python, statistics and probability, algorithms and A/B testing.

Sample question:  Given two tables, write a query to find the number of users that accepted Friend requests in the last month.

3. Take-Home Challenge

Take-homes are longer tests that may take several hours to complete. These challenges are designed to evaluate your ability to handle data, perform analysis and present your results effectively. Typically, these tests will ask you to perform and investigation on a dataset and present your findings.

Sample question:  Prepare a summary of sales and website data for the Vice President of Marketing. Include an overview of website traffic and sales, as well as areas for improvement.

4. On-site Interview

Data analyst on-site interviews typically consist of 3-5 hour-long interviews. They typically cover traditional technical SQL and statistics questions, as well as data analytics case studies and behavioral questions.

Sample question:  Describe an analytics project you worked on. What were some challenges you faced?

Different Types of Data Analyst Interview Questions

Interview Query regularly analyzes the contents of data analyst interviews. By tagging common keywords and mapping them back to question topics for over 10K+ tech companies, we’ve found that  SQL questions are asked most frequently .

In fact, in interviews for data analyst roles, SQL and data manipulations questions are asked 85% of the time.

Here are the types of technical interview questions data analysts get asked most frequently:

• Behavioral interview questions
• SQL and data processing
• Data analytics case studies
• Python, algorithms, and coding questions
• Statistics and probability
• A/B testing and experimentation
• Product metrics

Additionally, for more traditional data analyst roles, expect interview questions around:

• Data Visualization

Let’s first dive into how to approach and answer behavioral interview questions

Behavioral Interview Questions for Data Analysts

Behavioral questions in data analyst interviews  ask about specific situations you’ve been in, in which you had to apply specific skills or knowledge.

For many data analysts, behavioral questions can be fairly tough.

One tip: Always try to relate the question back to your experience and strengths.

1. Describe a time when you spotted an inconsistency. How did you respond?

Successful data analysts can help businesses identify anomalies and respond quickly.

For data sense questions, think about a time that you were able to spot an inconsistency in data quality, and how you eventually addressed it.

2. Talk about a time where you had to make a decision in a lot of uncertainty.

Interviewers want to see you demonstrate:

• Decisiveness –  Show the interviewer that you can make decisions  and  communicate your decision-making process.
• Self-direction –  Show that you are able to choose a path forward, deduce information, and create a plan of action.
• Adaptability –  Your response should show that you can adapt your decision-making in a challenging situation.

Here’s an example answer:  “In my previous job, I was working on a sales forecasting problem under a strict deadline. However, due to a processing error, I was missing the most recent data, and only had 3-year-old sales figures. The strategy I took was applying the growth factor to the data to establish correct correlation and variances. This strategy helped me deliver a close forecast and meet the deadline.”

3. How would you convey insights and the methods you use to a non-technical audience?

Interviewers ask this question to see if you can make complex subjects accessible and that you have a knack for communicating insights in a way that persuades people. Here’s a marketing analytics example response:

“I was working on a customer segmentation project. The marketing department wanted to better segment users. I worked on a presentation and knew the audience wouldn’t understand some of the more complex segmenting strategies, so I put together a presentation that talked about the benefits and potential trade-offs of segmenting options like K-means clustering.For each option, I created a slide to show how it worked, and after the presentation, we were able to have an informed discussion about which approach to use.”

4. How do you set goals and achieve them? Give us an example.

Interviewers want to see that you can set manageable goals and understand your process for achieving them. Don’t forget to mention the challenges you faced, which will make your response more dynamic and insightful. For example, you might say:

“Data visualization was something I struggled with in college. I didn’t have a strong design eye, and my visualizations were hard to read. In my last job, I made it a goal to improve, and there were two strategies that were most helpful. I took an online data visualization course, and I built a clip file of my most favorite visualizations. The course was great for building my domain knowledge. However, I felt I learned the most by building my clip file and breaking down what made a good visualization on my own.”

5. Describe a time when you solved a conflict at work.

This question assesses your ability to remain objective at work, that you communicate effectively in challenging situations, and that you remain calm under fire. Here’s an example response:

“In my previous job, I was the project manager on a dashboard project. One of the BI engineers wasn’t meeting the deadlines I had laid out, and I brought that up with him. At first, he was defensive and angry with me. But I listened to his concerns about the deadlines and asked what I could do to help. From our conversation, I learned he had a full workload in addition to this project. I talked with the engineering manager, and we were able to reduce some of his workload. He caught up quickly and we were able to finish the project on time.”

6. Give an example of a situation when you have shown effectiveness, empathy, humbleness, and adaptability.

This is a leadership question in disguise. If you can relate a time you were an effective leader, chances are you will easily incorporate all of these traits. For example:

“I was the lead on a marketing analytics project. We had a critical deadline to meet, but due to a data processing error, we were in danger of missing the deadline. The team morale was low, so I held a quick meeting to lay out a schedule, answer questions, and rally the team. That meeting gave the team the jolt it needed. We made the deadline, and I made sure leadership knew how hard each of the contributors had worked.”

7. Give me an example of a time when you failed on a project.

This question tests your resilience, how you respond to adversity, and how you learn from your mistakes. You could say:

“I had to give a presentation about a data analytics project to a client. One mistake I made was assuming the audience had more technical knowledge than they did. The presentation was received by a lot of blank stares. However, I knew the material about our findings was strong. I stopped for questions, and then, I jumped ahead to the visualizations and findings. This helped get the presentation on track, and by the end, the client was impressed. Now, whenever I have a presentation, I take time to understand the audience before I start working on it.”

8. Talk about an occasion when you used logic to solve a problem.

A strong response to this question shows that you can solve problems creativity and that you don’t just jump at the first or easiest solution. One tip: Illustrate your story with data to make it more credible.

Here’s what you could say:  “In my previous job, I was responsible for competitor research, and through my analysis, I noticed that our most significant competitors had increased sales 5% during Q1. This deviated significantly from our sales forecasts for these accounts. I found that we needed to update our competitor sales models with more recent market research and historical data. I tested the model adjustments, and ultimately, I was able to improve our forecasting accuracy by 15%.”

9. What do you do if you disagree with your manager?

Interviewers ask this question to gauge your emotional maturity, see that you can remain objective, and gain insights into your communication skills. Avoid subjective examples like my boss was a micromanager. Instead, you could say:

“One time, I disagreed with my manager over the process for building a dashboard, as their approach was to jump straight into the execution. I knew that it would be better to perform some planning in advance, rather than feeling our way through and reacting to roadblocks as they arose, so I documented a plan that could potentially save us time in development. That documentation and planning showed where pitfalls were likely to arise, and by solving for future issues we were able to launch the new dashboard three weeks early.”

10. How comfortable are you with presenting insights to stakeholders?

This question is asked to see how confident you are in your communication skills, and it provides insight into how you communicate complex technical ideas. With this question, talk about the various ways you make data and analytics accessible. Try to answer these questions:

• Do you create visualizations?
• What do you do to prepare for a data analytics presentation?
• What strategies do you use to make data more accessible?
• What presentation tools do you use?

11. Talk about a time you were surprised by the results of an analytics project.

This question is basically asking: Are you open to new ideas in your work? Analysts can get stuck on trying to prove their hypothesis, even if the data says otherwise. A successful analyst is OK with being wrong and listens to the data. You could say:

“While working on a customer analytics project, I was surprised to find that a subsegment of our customer base wasn’t actually responding to the offers we were providing. We had lumped the subsegment into a larger customer bucket, and had assumed that a broader segmentation wouldn’t make a difference. I relayed the insight to the marketing team, and we were able to reduce churn among this subsegment.”

12. Why are you interested in working for this company?

This question is super common in analyst behavioral interviews. However, it still trips a lot of candidates up. Another variation of this question would be: why did you want to work in data analytics.

In your response, your goal should be to convey your passion for the work and talk about what excites you about the company/role. You might focus on the company’s culture, a mentor who inspired you, recommendation you received, or someone in your network who’s connected with the company. A sample response:

“I’m excited by the possibility of using data to foster stronger social connections amongst friends and peers. I also like to ‘go fast’ and experiment, which fits into Meta’s innovative culture.”

13. Talk about a time when you had trouble communicating with stakeholders. How were you able to overcome it?

Interviewers ask questions like this to assess how you handle adversity and adapt. Don’t be afraid to share what went wrong. B do describe what you learned and how you apply it to future work.

Here’s a sample answer for a data analyst role:  “I presented a  data analytics project  to non-technical stakeholders, but my presentation was far too technical. I realized that the audience wasn’t following the technical aspects, so I stopped and asked for questions. I spent time clarifying the technical details until there were no questions left. One thing I learned was that it’s important to tailor presentations to the audience, so before I start a presentation, I always consider the audience.”

SQL Interview Questions for Data Analysts

Data analysts use SQL to query data to solve complex business problems or find answers for other employees. In general,  SQL data analyst questions  focus on analytics and reporting:

• Basic SQL Questions  - These include the basics, e.g. definitions, as well as beginner SQL queries.
• Analytics Questions  – Analytics based questions, you might have to understand what kind of report or graph to build first, and then write a query to generate that report. So it’s an extra step on top of a regular SQL question.
• Reporting Questions  – SQL reporting questions replicate the work many data or business analysts do on a day-to-day basis, e.g., writing queries.

Reporting interview questions focus on writing a query to generate an already-known output. Such as producing a report or a metric given some example table.

For analytics-based questions, you might have to understand what kind of report or graph to build first and then write a query to generate that report. So it’s an extra step on top of a regular SQL question.

Basic SQL Interview Questions

14. what are the different ways of handling null when querying a data set.

To handle such a situation, we can use three different operations:

• IS NULL − This operator returns true, if the column value is NULL.
• IS NOT NULL − This operator returns true, if the column value is not NULL. ‘
• <=> − This operator compares values, which (unlike the = operator) is true even for two NULL values.

15. What’s the difference between UNION and UNION ALL? (Asked by Facebook)

UNION and UNION ALL are SQL operators used to concatenate 2 or more result sets. This allows us to write multiple SELECT statements, retrieve the desired results, then combine them together into a final, unified set.

The main difference between UNION and UNION ALL is that:

• UNION : only keeps unique records
• UNION ALL : keeps all records, including duplicates

16. What is the difference between a SQL view and table? (Asked by Kaiser Permanente)

A table is structured with columns and rows. A view is a virtual table extracted from a database by writing a query.

17. What’s the difference between an INNER and OUTER JOIN ?

The  difference between an inner and outer  join is that inner joins result in the intersection of two tables, whereas outer joins result in the union of two tables.

18. What is the difference between WHERE and HAVING ?

The WHERE clause is used to filter rows before grouping, and HAVING is used to exclude records after grouping.

19. When do you use the CASE WHEN function?

CASE WHEN lets you write complex conditional statements on the SELECT clause, and also allows you to pivot data from wide to long formats.

20. What is the difference between DELETE TABLE and TRUNCATE TABLE in SQL?

Although they’re both used to delete data, a key difference is that DELETE is a Database Manipulation Language (DML) command, while TRUNCATE is a Data Definition Language (DDL) command.

Therefore, DELETE is used to remove specific data from a table, while TRUNCATE removes all the rows of a table without maintaining the structure of the table.

Another difference: DELETE can be used with the WHERE clause, but TRUNCATE cannot. In this case, DELETE TABLE would remove all the data from the table, while maintaining the structure. TRUNCATE would delete the entire table.

21. How would you pull the date from a timestamp in SQL?

EXTRACT allows us to pull temporal data types like date, time, timestamp, and interval from date and time values.

22. Write a SQL query to select all records of employees with last names between “Bailey” and “Frederick”.

For this question, assume the table is called “Employees” and the last name column is “LastName”.

23. What is the ISNULL function? When would you use it?

The ISNULL function returns an alternative value if an expression is NULL . Therefore, if you wanted to add a default value for NULL values, you would use ISNULL . For example in the statement:

NULL price values would be replaced with 50.

Reporting SQL Questions

24. we have a table with an id and name field. the table holds over 100 million rows and we want to sample a random row in the table without throttling the database. write a query to randomly sample a row from this table..

In most SQL databases, there exists a RAND() function which normally we can call:

The function will randomly sort the rows in the table. This function works fine and is fast if you only have, let’s say, around 1,000 rows. It might take a few seconds to run at 10K. And then at 100K maybe you have to go to the bathroom or cook a meal before it finishes.

What happens at 100 million rows?

Someone in DevOps is probably screaming at you.

Random sampling is important in SQL with scale. We don’t want to use the pre-built function because it wasn’t meant for performance. But maybe we can re-purpose it for our own use case.

We know that the RAND() function actually returns a floating point between 0 and 1. So if we were to instead call:

We would get a random decimal point to some Nth degree of precision. RAND() essentially allows us to seed a random value. How can we use this to select a random row quickly?

Let’s try to grab a random number using RAND() from our table that can be mapped to an id. Given we have 100 million rows, we probably want a random number from 1 to 100 million. We can do this by multiplying our random seed from RAND() by the max number of rows in our table.

We use the CEIL function to round the random value to an integer. Now we have to join back to our existing table to get the value.

What happens if we have missing or skipped id values, though? We can solve for this by running the join on all the ids which are  greater or equal than our random value  and selecting only the direct neighbor if a direct match is not possible.

As soon as one row is found,  we stop (LIMIT 1) . And we read the rows according to the index (ORDER BY id ASC). Now our performance is optimal.

25. Given a table of job postings, write a query to breakdown the number of users that have posted their jobs once versus the number of users that have posted at least one job multiple times.

Hint:  We want the value of two different metrics, the  number of users that have posted their jobs once  and the  number of users that have posted at least one job multiple times . What does that mean exactly?

26. Write a query to get the current salary for each employee.

More context .  Let’s say we have a table representing a company payroll schema.

Due to an ETL error, the employees table instead of updating the salaries every year when doing compensation adjustments, did an insert instead. The head of HR still needs the current salary of each employee.

27. Write a query to get the total amount spent on each item in the ‘purchases’ table by users that registered in 2023.

More context.  Let’s say you work at Costco. Costco has a database with two tables. The first is users composed of user information, including their registration date, and the second table is purchases which has the entire item purchase history (if any) for those users.

Here’s a process you can use to solve this question:

• You can use INNER JOIN or JOIN to connect tables users and purchases on the user_id column
• You can filter the results by using the WHERE clause
• Use GROUP BY to aggregate items, and apply the SUM() function to calculate the amount spent

28. Write a query to get the cost of all transactions by user ordered by total cost descending.

Here’s a code solution:

29. Given a table of transactions and a table of users, write a query to determine if users tend to order more to their primary address versus other addresses.

Hint:  This question has been asked in  Amazon data analyst interviews , and the first step is getting data from the users table to the transactions table. This can be done using a JOIN, based on a common column between the tables. How do we identify when the addresses match? We can use the CASE WHEN statement to produce a flag to use in further calculations. Finally, we need the percentage of all the transactions made to the primary address rounded to two decimals.

30. Write a query to get the top three users that got the most upvotes on their comments.

You’re provided with three tables representing a forum of users and their comments on posts and are asked to find the top three users with the most upvotes in the year 2020. Additionally, we’re told that upvotes on deleted comments and upvotes that users make on their own comments don’t matter.

Hint:  The trickiest part about this question is performing your JOINs on the proper fields. If you join two of our tables on the wrong key, you could make things difficult, or even impossible, for yourself later on.

31. Write a query to identify customers who placed more than three transactions each in both 2019 and 2020.

In this question, you’re given two transactions and users.

Hint:  Start by joining the transactions and users tables. Use INNER JOIN or JOIN.

Analytics SQL Questions

32. given a table of search results, write a query to compute a metric to measure the quality of the search results for each query..

search_results  table

You want to be able to compute a metric that measures the precision of the ranking system based on position. For example, if the results for dog and cat are….

…we would rank ‘cat’ as having a better search result ranking precision than ‘dog’ based on the correct sorting by rating.

Write a query to create a metric that can validate and rank the queries by their search result precision. Round the metric (avg_rating column) to 2 decimal places.

33. Given the two tables, write a SQL query that creates a cumulative distribution of number of comments per user. Assume bin buckets class intervals of one.

Hint:  What is a cumulative distribution exactly? If we were to imagine our output and figure out what we wanted to display on a cumulative distribution graph, what would the dataset look like?

34. We are given a table of bank transactions with three columns: user_id, a deposit or withdrawal value (determined if the value is positive or negative), and created_at time for each transaction.

Write a query to get the total three day rolling average for deposits by day.

Usually, if the problem states to solve for a moving/rolling average, we’re given the dataset in the form of a table with two columns, the date and the value.

This problem, however, is taken one step further with a table of just transactions with values conditioned to filtering for only deposits, and remove records representing withdrawals, denoted by a negative value (e.g. -10).

35. Given a table of user experiences representing each person’s work experiences, write a query to determine if a data scientist gets promoted faster, if they switch jobs more frequently.

More context.  Let’s say we’re interested in analyzing the career paths of data scientists. We have job titles bucketed into data scientist, senior data scientist, and data science manager. We’re interested in determining if a data scientist who switches jobs more often ends up getting promoted to a manager role faster than a data scientist that stays at one job for longer.

This question has been asked in Google data analyst interviews, and it requires a bit of creative problem solving to understand how we can prove or disprove the hypothesis. The hypothesis is that data scientists that end up switching jobs more often get promoted faster.

Therefore, in analyzing this dataset, we can prove this hypothesis by separating the data scientists into specific segments on how often they jump in their careers. How would you do that?

36. Write a query to get the distribution of the number of conversations created by each user by day in the year 2020.

Our focus is getting our key metric of a number of new conversations created by day in a single query. To get this metric, we have to group by the date field and then group by the distinct number of users messaged. Afterward, we can then group by the frequency value and get the total count of that as our distribution.

37. Write a query that could display the percentage of users on our forum that would be acting fraudulently in this manner.

More context.  We’re given three tables representing a forum of users and their comments on posts. We want to figure out if users are creating multiple accounts to upvote their own comments. What kind of metrics could we use to figure this out?

38. Uber users are complaining that the pick-up map is wrong. How would you verify how frequently this is actually happening?

Hint.  What metric would help you investigate this problem?

39. What strategies could we try to implement to increase the outreach connection rate?

More context.  Let’s say that Facebook account managers are not able to reach business owners after repeated calls to try to onboard them onto a new Facebook business product. Assume that we have training data on all of the account manager’s outreach in terms of calls made, calls picked up, time of call, etc…

One option would be to investigate when calls are most likely to be connected. Could changing our approach here improve connection rate?

40. You’re analyzing churn on Facebook. How would you investigate if a disparity exists in retention on different Facebook platforms?

Follow-up question.  How would you investigate the causes of such a disparity?

Data Analytics Case Study

Data analytics case study questions  combine a rotating mix of product intuition, business estimation, and data analytics.

Case questions come up in interviews when the job responsibilities lean to more of a heavy analytics space with an  emphasis on solving problems and producing insights for management.

Many times data analysts will transition into a heavy analytics role when they’re required to take on more scope around the product and provide insights that upper level management can understand and interpret.

So data analytics case study questions will focus on a particular problem and you will be judged on how you break down the question, analyze the problem, and communicate your insights.

Here’s an  example data analytics case study question:

41. Given a table of Stack Overflow posts data, suggest three metrics to monitor the health of the community.

Community members can create a post to ask a question, and other users can reply with answers or comments to that question. The community can express their support for the post by upvoting or downvoting.

post_analytics table:

More context.  You work at Stack Overflow on the community team that monitors the health of the platform. Community members can create a post to ask a question, and other users can reply with answers or comments to that question. The community can express their support for the post by upvoting or downvoting.

42. Write the queries for these metrics in SQL.

This is a classic data analytics case study. A  question like this  is designed to assess your data intuition, product sense, and ability to isolate key metrics.

Remember:  There isn’t one correct answer, but usually, the conversation should head in a similar direction.

For example, this question asks about community health. Broadly, there are several metrics you’ll want to consider: Growth rate, engagement, and user retention would provide insights into the community’s health.

The challenge with this question is to determine how to measure those metrics with the data provided.

43. Describe an analytics experiment that you designed. How were you able to measure success?

Case questions sometimes take the form of behavioral questions. Data analysts get tasked with experimenting with data to test new features or campaigns. Many behavioral questions will ask about experiments but also tap into how you approach measuring your results.

With questions like these, be sure to describe the objective of the experiment, even if it is a simple A/B test. Don’t be afraid to get technical and explain the metrics you used and the process you used to quantify the results.

44. An online marketplace introduces a new feature that lets buyers and sellers conduct audio chats. Write a query to represent if the feature is successful or not.

Bonus question.  How would you measure the success of this new feature?

See a step-by-step solution to this data analytics case study problem.

45. Write a query to prove or disprove the hypothesis: CTR is dependent on the search result rating.

More context.  You’re given a table that represents search results from searches on Facebook. The query column is the search term, the position column represents each position the search result came in, and the rating column represents the human rating from 1 to 5, where 5 is high relevance and 1 is low relevance.

Each row in the search_events table represents a single search with the has_clicked column representing if a user clicked on a result or not. We have a hypothesis that the CTR is dependent on the search result rating.

46. A revised new-user email journey boosts conversion rates from 40% to 43%. However, a few months prior, CVR was 45%. How would you investigate if the new email journey caused the increase in CVR?

See a step-by-step solution to this problem on YouTube.

Python Coding Questions for Data Analysts

Python coding questions for data analysts are usually pretty simple and not as difficult as the ones seen on Leetcode. Mainly most interviewers just want to test basic knowledge of Python to the point that they know you can write scripts or some basic functions to move data between SQL and Excel or onto a dashboard.

Most data analysts never write production code, such as their code is never under scrutiny because it’s not holding a website up or performing some critical business function.

Therefore, most coding questions for data analyst interviews are generally on the easier side and mostly test basic functions that are required for data manipulation. Pandas questions may also be asked in this round of the interview.

Here’s an  example Python coding question:

47. Write a function that can take a string and return a list of bigrams. (Asked by Indeed)

Bigrams are two words that are placed next to each other. To actually parse them out of a string, we need to first split the input string.

We would use the Python function .split() to create a list with each individual word as an input. Create another empty list that will eventually be filled with tuples.

Then, once we’ve identified each individual word, we need to loop through k-1 times (if k is the amount of words in a sentence) and append the current word and subsequent word to make a tuple. This tuple gets added to a list that we eventually return. Remember to use the Python function .lower() to turn all the words into lowercase!

48. Explain negative indexing. What purpose does it serve?

Negative indexing is a function in Python that allows users to index arrays or lists from the last element. For example, the value -1 returns the last element, while -2 returns the second-to-last element. It is used to display data from the end of a list, or to reverse a number or string.

Example of negative indexing:

49. What is a compound data type in Python?

Compound data structures are single variables that represent multiple values. Some of the most common in Python are:

• Lists - A collection of values where the order is important.
• Tuples - A sequence of values where the order is important.
• Sets - A collection of values where membership in the set is important.
• Dictionaries - A collection of key-value pairs, where you can access values based on their keys.

50. What is the difference between Python lists, tuples, and sets? When should you use one over the other?

Lists, tuples, and sets are compound data types that serve a similar purpose: storing collections of items in Python. However, knowing the differences between each of them is crucial for compute and memory efficiency.

• Lists are mutable collections that are ordered and allow duplicate elements. They are versatile and offer a broad range of operations such as accessing, adding, and removing items. They are suitable when the order of items matters or when you need to change the collection over time.
• Tuples are similar to lists in that they are ordered collections. However, they are immutable, meaning you cannot change their content once defined. Tuples are faster than lists, and they can be used in situations where the content will remain constant.
• Sets are unordered collections that do not allow duplicate elements. Because they are unordered, you cannot access elements by an index. Sets are faster than both lists and tuples for membership testing, i.e., checking if an item is in the collection. They are also beneficial when you need to remove duplicates from a collection or perform mathematical set operations such as union, intersection, and difference.

51. How would you find duplicate values in a dataset for a variable in Python?

You can check for duplicates using the Pandas duplicated() method. This will return a boolean series which is TRUE only for unique elements.

52. What is list comprehension in Python? Provide an example.

List comprehension is used to define and create a list based on an existing list. For example, if we wanted to separate all the letters in the word “retain,” and make each letter a list item, we could use list comprehension:

We can also use list comprehension for filtering. For example, to get all the vowels in the word “retain”, we do the following:

If you are concerned about duplicate values, you can opt for sets instead, by replacing “[]” with “{}”.

53. What is sequence unpacking? Why is it important?

Sequence unpacking is a python operation that allows you to de-structure the elements of a collection and assign them directly to variables without the need for iteration. It provides a terse method for mapping variables to the elements of a compound data structure. For example:

We can even swap the elements of two variables without the use of a third variable:

If the size of a collection is unclear, you can use the * operator on a variable to assign all extra items to said variable:

54. Write a function that takes in a list of dictionaries with a key and list of integers and returns a dictionary with the standard deviation of each list.

Hint:  need to use the equation for standard deviation to answer  this question . Using the equation, allows us to take the sum of the square of the data value minus the mean, over the total number of data points, all in a square root.

55. Given a list of timestamps in sequential order, return a list of lists grouped by week (7 days) using the first timestamp as the starting point.

This question  sounds like it should be a SQL question doesn’t it? Weekly aggregation implies a form of GROUP BY in a regular SQL or pandas question. In either case, aggregation on a dataset of this form by week would be pretty trivial.

56. Given two strings A and B, return whether or not A can be shifted some number of times to get B.

Hint:  This problem is relatively simple if we work out the underlying algorithm that allows us to easily check for string shifts between the strings A and B.

57. Given two strings, string1 and string2, write a function is_subsequence to find out if string1 is a subsequence of string2.

Hint:  Notice that in the subsequence problem set, one string in this problem will need to be traversed to check for the values of the other string. In this case, it is string2.

Statistics and Probability Interview Questions

Statistics and probability questions for data analysts will usually come up on an onsite round as a test of basic fundamentals.

Statistics questions are more likely than probability questions to show up, as statistics are the fundamental building blocks for many analyst formulas and calculations.

58. Given uniform distributions X and Y and the mean 0 and standard deviation 1 for both, what’s the probability of 2X > Y? (Asked by Snapchat)

Given that X and Y both have a mean of 0 and a standard deviation of 1, what does that indicate for the distributions of X and Y?

Let’s look at  this question  a little closer.

We’re given two normal distributions. The values can either be positive or negative but each value is equally likely to occur. Since we know the mean is 0 and the standard deviation is 1, we understand that the distributions are also  symmetrical across the Y-axis .

In this scenario, we are equally likely to randomly sample a value that is greater than 0 or less than 0 from the distribution.

Now, let’s take examples of random values that we could get from each scenario. There are about six different scenarios here.

• X > Y: Both positive
• X > Y: Both negative
• X < Y: Both positive
• X < Y: Both negative
• X > Y: X is positive Y is negative
• X < Y: X is negative Y is positive

We can simulate a random sampling by equating that all six are equally likely to occur. If we play out each scenario and plug the variables into 2X > Y, then we see about half of the time the statement is true, or  50% .

Why is this the case? Generally if we go back to the fact that both distributions are symmetrical across the Y-axis, we can intuitively understand that if both  X and Y are random variables across the same distribution , we will see 2X as being on average double positive or double negative the value that Y is.

59. What is an unbiased estimator and can you provide an example for a layman to understand?

To answer  this question , start by thinking about how a biased estimator looks. Then, think about how an unbiased estimator differs. Ultimately, an estimator is unbiased if its expected value equals the true value of a parameter, meaning that the estimates are in line with the average.

60. Let’s say we have a sample size of N. The margin of error for our sample size is 3. How many more samples would we need to decrease the margin of error to 0.3?

Hint:  In order to decrease our margin of error, we’ll probably have to increase our sample size. But by how much?

61. What’s the Difference Between Correlation and Covariance?

Covariance measures the linear relationship of variables, while correlation measures the strength and direction of the relationship. Therefore, correlation is a function of a covariance. For example, a correlation between two variables does not mean that the change in variable X caused the change in variable Y’s value.

62. How would you describe probability distribution to a non-technical person?

Probability distributions represent random variables and associated probabilities of different outcomes. In essence, a distribution maps the probability of various outcomes.

For example, a distribution of test grades might look similar to a normal distribution, AKA bell curve, with the highest number of students receiving Cs and Bs, and a smaller percentage of students failing or receiving a perfect score. In this way the center of the distribution would be the highest, while outcomes at either end of the scale falling lower and lower.

63. What is a non-normal distribution? Provide an example.

A probability distribution is not normal if most of its observations do not cluster around the mean, forming the bell curve. An example of a non-normal probability distribution is a uniform distribution, in which all values are equally likely to occur within a given range. A random number generator set to produce only the numbers 1-5 would create such a not normal distribution, as each value would be equally represented in your distribution after several hundred iterations.

64. What is the probability that it’s raining in Seattle?

More context.  You are about to get on a plane to Seattle. You call 3 random friends in Seattle and ask each if it’s raining. Each has a 2⁄3 chance of telling you the truth and a 1⁄3 chance of messing with you by lying. All 3 friends tell you that “yes” it is raining.

Hint:  There are several ways to answer  this question . Given that a  frequentist approach  operates on the set of known principles and variables given in the original problem, you can logically deduce that P(Raining)= 1-P(Not Raining).

Since all three friends have given you the same answer as to whether or not it’s raining, what can you determine about the relationship between P(Not Raining) and the probability that each of your friends is lying?

65. If given a univariate dataset, how would you design a function to detect anomalies? What if the data is bivariate?

Before jumping into anomaly detection, discuss what the meaning of a univariate dataset is. Univariate means one variable. For example, travel time in hours from your city to 10 other cities is given in an example list below:

12, 27, 11, 41, 35, 22, 18, 43, 26, 10

This kind of single column-data set is called a univariate dataset. Anomaly detection is a way to discover unexpected values in datasets. The anomaly means data exists that is different from the normal data. For example, you can see below the dataset where one data point is unexpectedly high intuitively:

12, 27, 11, 41, 35, 22, 76767676, 18, 43, 26, 10

66. You want to look at mean and median for a dataset. When would you use one measure over the other? How do you calculate the confidence interval of each measure?

You should answer these questions in your response:

• Which measure has the widest application?
• What happens when the dataset has values that are way above or below most other values?
• How would your choice of metric be influenced by the data being non-continuous?

67. You have a biased and unbiased coin. You select a random coin and flip it two times. What is the probability that both flips result in the same side?

Hint:  The first step in solving this problem is to separate it into two instances– one where you grab the fair coin, and one where you grab the biased coin. Solve for the probabilities of flipping the same side separately for both.

68. What could be the cause of a capital approval rate decrease?

Capital approval rates have gone down for our overall approval rate. Let’s say last week it was 85% and the approval rate went down to 82% this week which is a statistically significant reduction.

The first analysis shows that all approval rates stayed flat or increased over time when looking at the individual products.

• Product 1: 84% to 85% week over week
• Product 2: 77% to 77% week over week
• Product 3: 81% to 82% week over week
• Product 4: 88% to 88% week over week

Hint:  This would be an example of Simpson’s Paradox which is a phenomenon in statistics and probability. Simpson’s Paradox occurs when a trend shows in several groups but either disappears or is reversed when combining the data.

69. How would you explain confidence intervals?

In probability, confidence intervals refer to a range of values that you expect your estimate to fall between if you were to rerun a test. Confidence intervals are a range that are equal to the mean of your estimate plus or minus the variation.

For example, if a presidential popularity poll had a confidence interval of 93%, encompassing a 50%-55% approval, it would be expected that, if you re-polled your sample 100 more times, 93 times the estimate would fall between the upper and lower values of your interval. Those other seven events would fall outside, which is to say either below the 50% or above 55%. More polling would allow you to get closer to the true population average, and narrow the interval.

70. You have to draw two cards from a shuffled deck, one at a time. What’s the probability that the second card is not an ace?

One question to add:  does order matter here? Is drawing an ace on the second card the same thing as drawing an ace on the first card and still drawing a second card? Let’s see if we can solve and prove this out.

We can generalize to two scenarios when drawing two cards of getting an ace:

• Drawing an ace on the first card and an ace on the second card
• Drawing not an ace on the first card and an ace on the second card

If we model the probability of the first scenario we can multiply the two probabilities of each occurrence to get the actual probability.

A/B Testing and Experimentation

A/B testing and experimentation questions for data analysts tend to explore the candidate’s ability to properly conduct A/B tests. You should have strong knowledge of p-values, confidence intervals, and assessing the validity of the experiment.

71. The PM checks the results of an A/B test (standard control and variant) and finds a .04 p-value. How would you assess the validity of the result? How would you assess the validity of the result?

In this  particular question , you’ll need to clarify the context of how the A/B test was set up and measured.

If we have an A/B test to analyze, there are two main ways in which we can look for invalidity. We could likely re-phrase the question to: How do you set up and measure an A/B test correctly?

Let’s start out by answering the first part of figuring out the validity of the set up of the A/B test:

1. How were the user groups separated?

Can we determine that the control and variant groups were sampled accordingly to the test conditions?

If we’re testing changes to a landing page to increase conversion, can we compare the two different users in the groups to see different metrics in which the distributions should look the same?

For example, if the groups were randomly bucketed, does the distribution of traffic from different attribution channels still look similar or is the variant A traffic channel coming primarily from Facebook ads and the variant B from email? If testing group B has more traffic coming from email then that could be a biased test.

2. Were the variants equal in all other aspects?

The outside world often has a much larger effect on metrics than product changes do. Users can behave very differently depending on the day of week, the time of year, the weather (especially in the case of a travel company like Airbnb), or whether they learned about the website through an online ad or found the site organically.

If the variants A’s landing page has a picture of the Eifel Tower and the submit button on the top of the page, and variant B’s landing page has a large picture of an ugly man and the submit button on the bottom of the page, then we could get conflicting results based on the change to multiple features.

Measurement

Looking at the actual measurement of the p-value, we understand that industry standard is .05, which means that 19 out of 20 times that we perform that test, we’re going to be correct that there is a difference between the populations.

However, we have to note a couple of things about the test in the measurement process.

What was the sample size of the test?

Additionally, how long did it take before the product manager measured the p-value? Lastly, how did the product manager measure the p-value and did they do so by continually monitoring the test?

If the product manager ran a T-test with a small sample size, they could very well easily get a p-value under 0.05. Many times, the source of confusion in AB testing is how much time you need to make a conclusion about the results of an experiment.

The problem with using the p-value as a stopping criterion is that the statistical test that gives you a p-value assumes that you designed the experiment with a sample and effect size in mind. If we continuously monitor the development of a test and the resulting p-value, we are very likely to see an effect, even if there is none. The opposite error is also common when you stop an experiment too early, before an effect becomes visible.

The number one most important reason is that we are performing a statistical test every time you compute a p-value and the more you do it, the more likely you are to find an effect.

How long should we recommend an experiment to run for then?  To prevent a false negative (a Type II error), the best practice is to determine the minimum effect size that we care about and compute, based on the sample size (the number of new samples that come every day) and the certainty you want, how long to run the experiment for, before starting the experiment.

72. How can you effectively design an A/B test? Are there times when A/B testing shouldn’t be used?

Split testing fails when you have unclear goals. That’s why it’s imperative to start backwards with that goal. Is it to increase conversions? Are you trying to increase engagement and time spent on page? Once you have that goal, you can start experimenting with variables.

73. How much traffic would you need to drive to a page for the result of an A/B test to be statistically significant?

Statistical significance - or having 95% confidence in the results - requires the right volume of data. That’s why most A/B tests run for 2-8 weeks. Comparing metrics like conversions is fairly easy to calculate. In fact, most A/B tools have built-in calculators.

74. How would you conduct an experiment to test a new ETA estimate feature in Uber? How would you know if your results were significant?

Hint:  A question like this asks you to think hypothetically about A/B testing. But the format is the same: Walk the interviewer through setting up the test and how you arrive at a statistically relevant result.

75. How would you explain P-value to someone who is non-technical?

The p-value is a fundamental concept in statistical testing. First, why does this kind of question matter? What an interviewer is looking for here is can you answer this question in a way that both conveys your understanding of statistics but can also answer a question from a non-technical worker that doesn’t understand why a p-value might matter.

For example, if you were a data scientist and explained to a PM that the ad campaign test has a .08 p-value, why should the PM care about this number?

76. Your company wants to test new marketing channels. How would you design an A/B test for the most efficient marketing spend?

The new channels include: Youtube Ads, Google search ads, Facebook ads, direct mail campaigns.

To start, you’d want to follow up with some clarifying questions and make some assumptions. Let’s assume, for example, that most efficient means lowest cost per conversion, and that we’ve been asked to spend evenly across all platforms.

77. You want to run an experiment, but found that the distribution of the dataset is not normal. What kind of analysis would you run and how would you measure which variant won?

Understanding whether your data abides by or violates a normal distribution is an important first step in your subsequent data analysis.

This understanding will change which statistical tests you want to use if you need to immediately look for statistical significance. For example, you cannot run a t-test if your distribution is non-normal since this test uses mean/average as a way to find differences between groups.

78. You want to A/B test pricing levels for subscriptions. The PM asks you to design a two-week test. How do you approach this? How do you determine if the pricing increase is a good business decision?

Hint:  Is A/B testing a price difference a good idea? Would it encourage users to opt-out of your test, if they were seeing different prices for a product?

Is there a better way to test pricing?

79. A survey shows that app users who use an optional location-sharing feature are “less happy” with the app as a whole. Is the feature actually causing users to be unhappy?

Causal relationships are hard to come by, and truly determining causality is tough as the world is full of confounding variables. Because of this, instead of causality, we can dissect the correlation between the location sharing feature and the user unhappiness level.

At its core, this interview question is testing how you can dig into the science and statistics behind their assumption. The interviewer is asking essentially a small variation of a traditional experimental design with survey research and wants to know how you would either validate or disprove this claim.

Product Metrics Data Analyst Questions

Metrics is a common  product analyst interview question  subject, and you’ll also see this type of question in product-oriented data analyst roles. In general, these questions test your ability to choose metrics to investigate problems or measure success. These questions require strong product sense to answer.

80. You’re given a list of marketing channels and their costs. What metrics would you use to determine the value of each marketing channel?

The first thing we’ll want to do when faced with an interview question like this one is to ask a few clarifying questions. Answer these questions first:

• What is the company’s business model?
• Is there one product or many?

Let’s say it’s a SaaS business that offers a free Studio model of their product, but makes their money selling enterprise subscriptions. This gives us a better sense of how they’re approaching their customers. They’re saying: here’s a good free tool, but you can pay to make it even better.

• How many marketing channels are there?

Imagine what your analysis would look like if the answer to this question was “a few.” Now imagine what your analysis would look like if the answer to this question was “hundreds.”

• Are some marketing channels bigger than others? What’s the proportion?

Mode could be spending 90% of its marketing budget on Facebook Ads and 10% on affiliate marketing, or vice versa. We can’t know unless we ask.

• What is meant by “the value of each marketing channel?”

Here’s where we start getting into the meat of the question.

81. A PM at Facebook comes to you and tells you that friend requests are down 10%. What do you do?

This question has been asked in Facebook data analyst interviews. See an example solution to this question on YouTube.

82. What are some reasons why the average number of comments per user would be decreasing, and what metrics would you look into?

More context.  Let’s say you work for a social media company that has just done a launch in a new city. Looking at weekly metrics, you see a slight decrease in the average number of comments per user from January to March in this city. The company has been consistently growing new users in the city from January to March.

Let’s model an example scenario to help us see the data.

• Jan: 10000 users, 30000 comments, 3 comments/user
• Feb: 20000 users, 50000 comments, 2.5 comments/user
• Mar: 30000 users, 60000 comments, 2 comments/user

We’re given information that total user count is increasing linearly, which means that the decreasing comments/user is not an effect of a declining user base creating a loss of network effects on the platform. What else can we hypothesize, then?

83. How would you measure the success of Facebook Groups?

Start here:  What is the point of Facebook Groups? Primarily we could say Facebook Groups provides a way for Facebook users to connect with other users through a shared interest or real-life/offline relationship.

How could we use the goals of Facebook Groups to measure success?

84. What kind of analysis would you conduct to recommend UI changes?

More context.  You have access to a set of tables summarizing user event data for a community forum app. You’re asked to conduct a user journey analysis using this data with the eventual goal of improving the user interface.

85. How would you measure the success of Uber Eats?

See a step-by-step solution for this question on YouTube.

86. What success metrics would you be interested in for an advertising-driven consumer product?

With this question, you might define success in terms of advertising performance. A few metrics you might be interested in are:

• Pageviews or daily actives (for apps)
• Conversion rate
• Number of purchases
• Cost per conversion

87. How do success metrics change by product type?

Let’s look at two examples: An eCommerce product like Groupon vs. a subscription product like Netflix.

E-commerce metrics tend to be related to conversions and sales. Therefore, you might be interested in the number of purchases, conversion rate, quarterly or monthly sales, and cost of goods sold.

Subscription products tend to focus more on subscriber costs and revenue, like churn rates, cost of customer acquisition, average revenue per user, lifetime value, and monthly recurring revenue.

88. Given a dataset of raw events, how would you come up with a measurement to define what a “session” is for the company?

More context.  Let’s say that you’re given event data from users on a social networking site like Facebook. A product manager is interested in understanding the average number of “sessions” that occur every day. However, the company has not technically defined what a “session” is yet.

The best the product manager can do is illustrate an example of a user browsing Facebook in the morning on their phone and then again during lunch as two distinct “sessions.” There must be a period of time where the user leaves Facebook to do another task before coming back again anew.

89. Some of the success metrics for the LinkedIn newsfeed algorithm are going up, while others are going down. What would you look at?

See a solution for this question on YouTube.

90. The number of products or subscriptions sold is declining. How would you investigate this problem?

This question provides you with a chance to show your expertise in analyzing sale metrics and KPIs. Some of the challenges you might bring up include competitor price analysis, examining core customer experiences, and investigating evolving customer desires. Your goal in your response should be to outline how you would perform root cause analysis.

Tip . Start with some clarifying questions like, What is the product? Who is the audience? How long has the decline in sales persisted?

91. You’re asked to investigate how to improve search results. What metrics would you investigate? What would you look at to determine if current search results are effective?

More context. Specifically, we want to improve search results for people looking for things to do in San Francisco.

Excel Interview Questions

Excel is still a widely used tool by data analysts, and in interviews, Excel questions typically focus on advanced features. These questions might ask for definitions, or you may be required to perform some Excel tasks.

Data analysts should also have strong knowledge of data visualization.  Data visualization interview questions  typically focus on design and presenting data, and may be more behavioral in nature. Be prepared to talk about how you make data accessible on dashboards.

92. Explain the Excel VLOOKUP function? What are the limitations of VLOOKUP?

This function allows users to find data from one column, and return a corresponding value from another.

For example, if you were analyzing a spreadsheet of customer data, you might use VLOOKUP to find a customer name and the corresponding phone number.

One  limitation of VLOOKUP  is that it only looks to the right of the column you are analyzing. For example, you couldn’t return a value from column A, if you used column B as the lookup column.

Another limitation is that VLOOKUP only returns the first value; if the spreadsheet contains duplicate records, you wouldn’t see any duplicates.

93. What is conditional formatting in Excel? When is a good time to use conditional formatting?

Conditional formatting allows users to  change the appearance of a cell based on specified conditions .

Using conditional formatting, you can quickly highlight cells or ranges of cells, based on your conditions. Data analysts use conditional formatting to visualize data, to identify patterns or trends, or to detect potential issues.

94. What are your favorite data visualization tools?

Data analysts will get asked what tools they have experience with. Choose a few that you’re most comfortable with and explain the features that you like.

95. What are some challenges you’ve experienced working with large volumes of data?

One tip: Think of questions like this in terms of Big Data’s 5 Vs: volume, velocity, variety, veracity and value.

96. Can you use multiple data formats in pivot tables?

Data can be imported from a variety of sources by selecting the Data tab and clicking Get External Data > From Other Sources. Excel worksheet data, data feeds, text files and other such data formats can be imported, but you will need to create relationships between the imported tables and those in your worksheet before using them to create a pivot table.

97. When creating a visualization, you suspect data is missing. What do you do?

In your answer, provide an overview of your data validation process. For example, you might say, “The first step I would do would be to prepare a data validation report, which reveals why the data failed.” Then, you might talk through strategies for analyzing the dataset or techniques to process missing data, like deletion or mean/median/mode imputation.

Visualization Interview Questions

Data visualization involves presenting data in a graphical or pictorial format. This allows viewers to see data trends and patterns that may not be easy to understand in text-based data. Tableau, Power BI, and Python libraries such as Matplotlib and Seaborn are some of the most commonly used tools for data visualization.

98. Discuss your experience with creating visualizations in tools such as Tableau, Power BI, or Python. What distinct features have you utilized in each?

This question requires you to detail your hands-on experience with the mentioned tools. It involves discussing specific features you have used in Tableau, Power BI, and Python, such as creating different types of charts, setting up dashboards, or using Python libraries like Matplotlib and Seaborn for custom visualizations.

99 . What is DAX and why is it important in Power BI?

DAX, or Data Analysis Expressions, is a library of functions and operators used to create formulas in Power BI, Analysis Services, and Power Pivot in Excel. These formulas, or expressions, are used to define custom calculations for tables and fields, and to manipulate data within the model.

100. Imagine you’re working on a sales report and you have a table of daily sales data. You want to calculate the monthly sales total. How could you use DAX to do this?

This question tests your understanding of DAX time-intelligence functions. A suitable response could be:

“ I would use a combination of the SUM and CALCULATE functions along with a Date table. First, I would create a measure using the SUM function to total the sales. Then, I would use the CALCULATE function along with the DATESMTD (Dates Month to Date) function to calculate the monthly total. The DAX expression would look something like this:

*Monthly Sales = CALCULATE(SUM(Sales[Daily Sales]), DATESMTD('Date'[Date])) “ *

101. Suppose a company has collected a large dataset on customer behavior, including demographics, transaction data, browsing history, and customer service interactions. You are tasked with presenting this data to the executive team, who are not data professionals. How would you go about this?

This question assesses your ability to analyze complex datasets and create straightforward, impactful visualizations. Your response might include:

“Understanding the audience is key. For an executive summary, it’s important to focus on high-level insights. I would start by performing exploratory data analysis to identify key trends and relationships within the data. From this, I could determine which aspects are most relevant to the executive team’s interests and strategic goals.

For visualization, I would use a tool like Tableau or Power BI, known for their user-friendly, interactive dashboards. To make the data more digestible, I would utilize various chart types such as bar graphs for categorical data comparison, line graphs for trend analysis, or pie charts for proportions.

To add an interactive element, I’d implement filters to allow executives to view data for different demographics, products, or time periods. It’s crucial to keep the design clean and ensure the visuals tell a clear story. For the presentation, I would walk them through the dashboard, explain key insights, and address any questions.”

102. You are working for an e-commerce company that needs a real-time dashboard to monitor sales across various product categories. Would you use Tableau or Power BI for this task? How would you leverage the chosen tool’s features to create the dashboard?

Your response should demonstrate your knowledge of both Tableau and Power BI and your ability to select the most appropriate tool for a specific task.

“For real-time sales monitoring, both Tableau and Power BI can be effective. However, if the company uses Microsoft’s suite of products and requires extensive integration with these services, I would lean towards Power BI as it’s part of the same ecosystem.

Power BI has robust real-time capabilities. I would leverage Power BI’s DirectQuery feature to connect to the sales database, ensuring the data displayed on the dashboard is always up-to-date. The tool also allows for streaming datasets that can be used for continuously streaming and updating data.

To visualize sales, I would design a dashboard that includes key metrics such as total sales, sales by product category, and changes in sales over time. I would also include slicers to allow users to filter data by region, time period, or other relevant dimensions.

Power BI also allows creating alerts based on KPIs that could notify the team when a sales target is reached or when there are significant changes in sales trends.”

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.

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.

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.

35 Case Interviews Examples from MBB / Big Four Firms

Studying case interview examples is one of the first steps in preparing for the  management consulting  recruitment process. If you don’t want to spend hours searching the web, this article presents a comprehensive and convenient list for you – with 35 example cases, 16 case books, along with a case video accompanied by detailed feedback on tips and techniques.

A clear understanding of “what is a case interview” is essential for effective use of these examples. I suggest reading our  Case Interview 101  guide, if you haven’t done so.

McKinsey case interview examples

Mckinsey practice cases.

• Electro-Light Case
• GlobaPharm Case
• National Education Case

What should I know about McKinsey Case interviews?

At McKinsey, case interviews often follow the interviewer-led format , where the interviewer asks you multiple questions for you to answer with short pitches.

How do you nail these cases? Since the questions can be grouped into predictable types, an efficient approach is to master each question type. However, do that after you’ve mastered the case interview fundamentals!

For a detailed guide on interviewer-led cases, check out our article on McKinsey Case Interview .

BCG & Bain case interview examples

Bcg practice cases.

• BCG – Written Case – Chateau Boomerang

Bain practice cases

• Bain – Mock Interview – Associate Consultant
• Bain – Mock Interview – Consultant

What should I know about BCG & Bain case interviews?

Unlike McKinsey, BCG and Bain case interviews typically follow the candidate-led format – which is the opposite of interviewer-led, with the candidate driving the case progress by actively breaking down problems in their own way.

The key to acing candidate-led cases is to master the case interview fundamental concepts as well as the frameworks.

Some BCG and Bain offices also utilize written case interviews – you have to go through a pile of data slides, select the most relevant ones to answer a set of interviewer questions, then deliver those answers in a presentation.

The Deloitte consultant recruitment process also features group case interviews , which not only test analytical skills but also place a great deal on interpersonal handling.

Accenture case interview examples

Accenture divides its cases into three types with very cool-sounding names.

Sorted in descending order of popularity, they are:

These are similar to candidate-led cases at Bain and BCG. albeit shorter – the key is to develop a suitable framework and ask the right questions to extract data from the interviewer.

These are similar to the market-sizing and guesstimate questions asked in interviewer-led cases – demonstrate your calculations in structured, clear-cut, logical steps and you’ll nail the case.

These cases have you sort through a deluge of data to draw solutions; however, this type of case is rare.

Capital One case interview examples

Capital One is the odd one on this list – it is a bank-holding company. Nonetheless, this being one of the biggest banks in America, it’s interesting to see how its cases differ from the consulting ones.

Having gone through Capital One’s guide to its cases, I can’t help but notice the less-MECE structure of the sample answers. Additionally, there seems to be a greater focus on the numbers.

Nonetheless, having a solid knowledge of the basics of case interviews will not hurt you – if anything, your presentation will be much more in-depth, comprehensive, and understandable!

Case interview example – Case video

The limitation of most official case interview examples is that they are either too short and vague, or in text format, or both.

To solve that problem for you, we’ve extracted a 30-minute-long, feedback-rich case sample from our Case Interview End-to-End Secrets Program .

This is a candidate-led, profitability case on an internet music broadcasting company called Pandora.

In 30 minutes, this candidate demonstrates the exact kind of shortcoming that most candidates suffer during real case interviews – they come in with sharp business senses, then hurt their own chances with inadequate techniques.

Here are seven notable areas where the candidate (and you) can improve:

Thanking Throughout the case, as especially in the opening, he should have shown more appreciation for the time the interviewer spent with him.

Structured opening The candidate’s opening of the case feels unstructured. He could have improved it by not mixing the playback and clarification parts. You can learn to nail the case in a 3-minute start through this video on How to Open Any Case Perfectly .

Explicitness A lot of the candidate’s thought process remains in his head; in a case interview, it’s better to be as explicit as possible – draw your issue tree out and point to it as you speak; state your hypothesis when you move into a branch; when you receive data, acknowledge it out loud.

Avoiding silence The silence in his case performance is too long, including his timeout and various gaps in his speech; either ask for timeout (and keep it as short as possible) or think out loud to fill those gaps.

Proactivity The candidate relies too much on the interviewer (e.g: asking for data when it can easily be calculated); you don’t want to appear lazy before your interviewer, so avoid this.

Avoiding repeating mistakes Making one mistake twice is a big no-no in consulting interviews; one key part of the consulting skill set is the ability to learn, and repeating your mistakes (especially if the interviewer has pointed it out) makes you look like someone who doesn’t learn.

Note-taking Given the mistakes this candidate makes, he’s probably not taking his notes well. I can show you how to get it right if you watch this video on Case Interview Note-Taking .

Nonetheless, there are three good points you can learn from the candidate:

The candidate sums up what he’s covered and announces his upcoming approach at the start and at key points in the case – this is a very good habit that gives you a sense of direction and shows that you’re an organized person.

The candidate performs a “reality check” on whether his actions match the issue tree; in a case interview it’s easy to lose track of what you’re doing, so remember to do this every once in a while.

The candidate prompts the interviewer to give out more data than he asked for; if anything, this actually matches a habit of real consultants, and if you’re lucky, your interviewer may actually give out important pieces you haven’t thought of.

These are only part of the “ninja tips” taught In our Case Interview E2E Secrets Program – besides the math and business intuition for long-term development, a key feature is the instant-result tips and techniques for case interviews.

Once you’ve mastered them, you can nail any case they throw at you!

For more “quality” practice, let’s have a mock case interview with former consultants from McKinsey, BCG, Bain, Oliver Wyman, Strategy& and many other consulting firms. They will help you identify your problem areas and give you actionable feedback, making your preparation much easier and faster.

Hi! This is Kim and welcome to another performance in the Tips & Techniques part of our amazing End-to-end program. You are about to hear a really interesting performance.

There is a common Myth that Profitability cases are easier. Well, for beginners, that’s may make sense, but I would argue that Profitability cases can be really tricky and candidates without good foundation will make about the same level of mistakes regardless of type of cases given.

The profitability case we are about to watch will show that. It’s a very unconventional

Profitability. It started out like a typical one but getting more and more tricky toward the end.

The candidate is fairly good in term of business intuition, but the Tips & Techniques aspect needs a lot of fine tune! Now let’s go ahead and get started! 

It’s actually a little better to playback the case information and ask clarifications. The candidate does not distinguish between the two and do both at a same time. Also, the candidate was asking these clarifications in an unorganized and unstructured fashion. This is not something terrible, but could have been better, especially when this is the very first part of the case, where the crucial first impression is being formed.

My pitch would sound like this:

“That’s a very interesting problem and I am happy to get the chance to solve it. First of all let me tell you my understanding of the case context and key objectives. Then I would like to ask a few clarifying questions regarding a few terminology and concepts. Both of these are to make sure that I will be solving the right problem.

So here is my understanding of the case: The client is ABC. Here are some DEF facts about the situation we just talked about. And the key case question is XYZ.

Does that correctly and adequately summarize the case?”

Once the interviewer confirms, I would move to the clarification part as follows: “Now I would like to ask a few clarification questions. There are three of them: No 1, … No 2, … and No 3, …”

You may see above pitch as obvious but that’s a perfect example of how you should open any cases. Every details matters. We will point out those details in just a second. But before we do that, it’s actually very helpful if you can go back, listen carefully to the above pitch, and try to point out the great components yourselves. Only after that, go back to this point and learn it all together.

Alright, let’s break down the perfect opening.

First of all, you hear me say: “That’s a very interesting problem and I am happy to get a chance to solve it”. This seems trivial but very beneficial in multiple ways:

1. I bought myself a couple of seconds to calm down and get focused. 2. By nature, we as human unconsciously like those who give us compliments. Nothing better than opening the case with a modest compliment to the interviewer.

And (c) I showed my great attitude towards the case, which the interviewer would assume is the same for real future consulting business problems.

You should do that in your interviews too. Say it and accompany it with the best smile you can give. It shows that you are not afraid of any problems. In fact, you love them and you are always ready for them.

Secondly, I did what I refer to as the “map habit”, which is to always say what you are about to do and then do it. Just like somebody in the car showing the drivers the route before cruising on the road. The driver would love it. This is where I said: “Let me tell you my understanding of the case context and key objectives. Then ABC…”.

Third, right at the beginning of the case, I try to be crystal clear and easy to follow. I don’t let the interviewer confused between playing the case vs. asking clarification questions. I distinguish between the two really carefully. This habit probably doesn’t change the outcome of how the case goes that much, but it certainly significantly changes the impression the interviewer has of me.

Fourth, in playing back the case, each person would have a different way to re-phrase. But there are three buckets to always include:

1. Who is the client 2. The facts regarding the client and the situation and (c) The key question and the objective of the case.

Fifth, after playing the case context and objectives, I pause for a second and ALIGN with the interviewer: “Does it correctly and adequately summarize the case?”. This is a habit that every consulting manager loves for young consultants to do. Nobody wants first-year folks to spend weeks of passion and hard-work building an excel model that the team can’t use. This habit is extensively taught at McKinsey, Bain and BCG, so therefore interviewers would love somebody that exhibits this habit often in case interview.

Lastly, when asking clarification questions, you hear me number them very carefully to create the strong impression that I am very organized and structured. I said I have three clarifying questions. Then I number them as I go through each. No.1, No.2, and No.3.

Sometimes, during interviews it’s hard to know exactly how many items you are going to get. One way is to take timeout often to carefully plan your pitch. If this is not possible in certain situations, you may skip telling how many items you have; but you should definitely still number your question: No.1, No.2; and so on. 

Just a moment ago, the candidate actually exhibited a good habit. After going through his clarification questions, the candidate ended by asking the “is there anything else” question. In this case, I actually give out an important piece of data.

Though this is not very common as not every interviewer is that generous in giving out data. But this is a habit management consultants have to have every day when talking to experts, clients, or key stakeholders. The key is to get the most data and insights out of every interview and this is the type of open-ended question every consultant asks several times a day.

To show of this habit in a case interview is very good!

There are three things I would like you to pay attention to:

First, it took the candidate up to 72 seconds to “gather his thoughts”. This is a little too long in a case interview. I intentionally leave the 72 seconds of silence in the recording so you get an idea of how long that is in real situations. But it’s worth-noting here is not only that. While in some very complicated and weird cases, it’s ok to take that long to really think and gather ideas. In this case, the approach as proposed by the candidate is very simple. For this very approach, I think no more than 15 to 20 seconds should be used.

No.2, with that said, I have told I really like the fact that this candidate exhibits the “map” habit. Before going straight to the approach he draws the overall approach first.

No.3. You also see here that the candidate tried to align the approach with me by asking my thoughts on it. As I just said on the previous comment, this is a great habit to have. Not only does it help reduce chance of going into the wrong direction in case interviews, but it also creates a good impression. Consulting interviewers love people doing it often!

Here we see a not-really-bad response that for sure could be much better. The candidate was going into the first branch of the analysis which is Revenue. I would fix this in 3 aspects:

First, even though we just talked about the overall approach, it’s still better to briefly set up the issue tree first then clearly note that you are going into one branch.

Second, this is not a must, but I always try to make my hypothesis as explicitly clear as possible. Here the candidate just implicitly made a hypothesis that the problem is on the revenue side. The best way to show our hypothesis-driven mindset is to explicitly say it.

Third, you hear this a ton of times in our End-to-End program but I am going to repeat it again and again. It is better to show the habit of aligning here too. Don’t just go into revenue, before doing that, give the interviewer a chance to agree or to actually guide you to Cost.

So, summarizing the above insights, my pitch would sound something like this:

“So as we just discussed, a profit problem is either caused by revenue or by cost. Unless you would like to go into cost first, let’s hypothesize that the problem is on revenue side. I would like to look deeper into Revenue. Do we have any data on the revenue?”

And while saying this, you should literally draw an issue tree and point to each as you speak.

There is an interesting case interview tip I want to point out here. Notice how the candidate responds after receiving two data points from me. He went straight into the next question without at least acknowledging the data received and also without briefly analyzing it.

I am glad that the candidate makes this mistakes… well, not glad for him but for the greater audience of this program. I would like to introduce to you the perfect habit of what you should react and do every time you have any piece of data during case interviews. So three things you need to do:

Step 1: Say … that’s an interesting piece of data. This helps the interviewer acknowledge that you have received and understand the data. This also buys you a little time. And furthermore, it’s always a good thing to give out modest compliments to the interviewer.

Step 2: Describe the data, how it looks, is there any special noteworthy trend? In this case, we should point out that revenue actually grew by more than 50%.

Also notice here that I immediately quantified the difference in specific quantitative measurement (in this case, percentage). Saying revenue went up is good, but it’s great to be able to say revenue went up by more than 50%.

Step 3: Link the trend identified back to the original case question and the hypothesis you have. Does it prove, disprove, or open up new investigation to really test the hypothesis? In this case, this data piece actually opened up new investigating areas to test the hypothesis that the bottleneck is within revenue.

My sample pitch for this step 3 would sound like this: “It’s interesting that revenue went up quite a bit. However, to be able to fully reject our hypothesis on the revenue, I would like to compare our revenue to that of the competitors as well.”

Then only at this point, after going through 3 steps above, I ask for the competitors’ revenue like the candidate did.

Notice here that I ended up asking the same question the candidate did. This shows that the candidate does have a good intuition and thought process. It’s just that he did all of these implicitly on his head.

In consulting case interview, it’s always good to do everything as explicitly as possible. Not only is it easier to follow but it helps show your great thought process.

How to Solve Amazon Case Study

Solving Amazon case study questions is not difficult if you know how to approach them. Here are strategies for solving Amazon case study questions:

Understand the Case Before You

Before you attempt to answer any case before you, you should understand it well. The interview will start with the interviewer intimating you on a situation. The interviewer will start with the background information on the case, where you have to be attentive. Follow the scenario and note all the points. Ensure that you understand the situational context and the objective of the case. Know the essence of the information.

You are at liberty to ask questions to clarify any part that is unclear to you. You can summarize the story to the interviewer to ascertain that you understand what you are meant to understand. The essence is to ensure that you grasp the objective of the situation. Understanding the case is essential to passing the test because it will guide you in answering the intended question.

Organize the Problem

Once the interviewer has narrated the case to you, you have to organize every bit of the information to enable you to answer the questions logically. It is like developing a framework for answering the question. At this point, you have to brainstorm on the case before you. Note your ideas and then organize them logically.

At the brainstorming stage, your ideas may not be organized. You are at liberty to ask the interviewer to give you some minutes. Then you organize your thoughts and ideas in order. Categorize your ideas and arrange them accordingly.

When you are done, intimate the interviewer with your ideas and framework. The interviewer may offer some advice, ask questions, and give you feedback. This aspect is essential because it tells you how well aligned you are with the whole case before you.

Start Solving the Case

Now that you are sure you are on track, you can start answering the question. Using your framework, you will start attending to the different aspects of the case. The process of answering the question will depend on whether the interviewer is leading the interview or the candidate is leading it. If the interviewer is leading the interview, he will tell you the aspect of your framework to start working from.

If the interview is candidate-led, you can decide the aspect of your framework to start working from. You will give reasons why you have chosen to start from that angle. At this stage, you should not bother with starting wrong. There is no straightjacket approach to solving the case.

Attend to Quantitative Challenges

The case study question may have a quantitative angle to it. For example, you may be asked a question that involves figures and estimates. You can start solving the problem with mathematical calculations.

Attend to Qualitative Challenges

The Amazon cases study question may involve qualitative questions. For example, you may be asked questions involving a business situation and asked to proffer a solution or provide your opinion on a critical business situation. Answering this question involves a structural and careful arrangement of your ideas. State your approach and justify that approach. Then, go ahead to solve the problem following your approach.

Summarize your Solution and Tender a Recommendation

At this point, you should round off your answers, summarize your points, and tender recommendations. You should give reasons for your recommendations. You can also include further actions or steps you would have taken if you had more data and time. They can cover aspects of your framework that you have not developed fully due to time or some questions that you did not answer in-depth.

Examples of Amazon Case Study Question and Solution

As stated already, Amazon case study questions are meant to test your problem-solving skills. The interviewer will ask you questions based on actual situations to determine your suitability for the job. Among others, they look out for your business acumen, communication, and leadership skills. Here is a possible case:

Case question: The company wants to acquire a small business and aspire to improve net profits from $3,000 to $6,000 within a month. How do you think we can achieve this?

For a question like this, the focus is on your mindset as a business analyst, thinking capacity, and business acumen. They want to know your mindset, whether positive or negative. It is easy for some people to think that it is impossible to double profit in a month. Your answer should include a positive statement on how much this is positive.

Then you will talk about the strategies that can make this possible. The company can achieve a doubling profit within a month using effective marketing and acquisition points and diligence. First off, the company should be diligent in choosing a business to acquire. Contrary to many business acquisition models that look at the business’s yearly growth or how lucrative the market for the business niche is, the company should go for a growing business. If the business grows by 5% monthly, it will make a positive purchase.

Then, the company has to consider the business’s branding. If it has a strong market presence, then Amazon’s marketing strategy will have a springboard to scale from. If the business is growing, there is the possibility of making more than triple the net profit in the third month because the growth would bring in more profit.

Other essential points to consider when looking to get a good deal are low competition, positive reviews, and the quick wins the business promises. Also, analyze every aspect of the business and ensure that it passes the test.

The company’s marketing skills will set the company on a high speed to rake in more profit. You can discuss the impact of marketing skills like media coverage, ads, promos, and so on. This response shows you are passionate about the company’s expansion, but you are also diligent and look out for the company’s positive move.

What is a Google Case Interview?

Google case interviews, also known as Google case study interviews, are 30- to 45-minute exercises in which you are placed in a hypothetical business situation and are asked to find a solution or make a recommendation.

To do this, you’ll create an overall framework that shows what approach you would take to solve the case. Then, you’ll collaborate with the interviewer, answering a mix of quantitative and qualitative questions that will give you the information and data needed to develop an answer. At the end of the case, you’ll deliver your recommendation.

Case interviews have traditionally been used by consulting firms to assess a candidate’s potential to become a successful consultant, but many companies with ex-consultants now use them to assess an interview candidate’s capabilities. Since Google hires so many former consultants in its business roles, you’ll likely encounter at least one case interview in your interview process.

The business problems that you’ll be given in a Google case interview will likely be real challenges that Google faces today:  

• How can Google increase its revenues from enterprise businesses?
• How can Google reduce costs among its customer service call centers while maintaining customer satisfaction?
• Google has seen a steep decline in the number of Google searches in Japan. What is causing this decline and what should Google do to address this?
• How can Google improve customer retention among small and medium-sized businesses?

Depending on what team at Google you are interviewing for, you’ll likely be given a business problem that is relevant to that specific team.

Although there is a wide range of business problems you could possibly be given in your Google case interview, the fundamental case interview strategies to solve each problem is the same. If you learn the right strategies and get enough practice, you’ll be able to solve any Google case interview.

Why does Google Use Case Interviews?

Google uses case interviews because your performance in a case interview is a measure of how well you would do on the job. Google case interviews assess a variety of different capabilities and qualities needed to successfully complete job duties and responsibilities.

Google’s case interviews assess five major qualities:

• Logical, structured thinking : Can you structure complex problems in a clear, simple way?
• Analytical problem solving : Can you read, interpret, and analyze data well?
• Business acumen : Do you have sound business judgment and intuition?
• Communication skills : Can you communicate clearly, concisely, and articulately?
• Personality and cultural fit : Are you coachable and easy to work with?

Since all of these qualities can be assessed in just a 30- to 45-minute case, Google case interviews are an effective way to assess a candidate’s capabilities.

The 6 Steps to Solve Any Google Case Interview

In general, there are six steps to solve any Google case interview or case study interview.

1. Understand the case

Your Google case interview will begin with the interviewer giving you the case background information. While the interviewer is speaking, make sure that you are taking meticulous notes on the most important pieces of information. Focus on understanding the context of the situation and the objective of the case.

Don’t be afraid to ask clarifying questions if you do not understand something. You may want to summarize the case background information back to the interviewer to confirm your understanding of the case.

The most important part of this step is to verify the objective of the case. Not answering the right business question is the quickest way to fail a case interview.

2. Structure the problem

The next step is to develop a framework to help you solve the case. A framework is a tool that helps you structure and break down complex problems into smaller, more manageable components. Another way to think about frameworks is brainstorming different ideas and organizing them into different categories.

For a complete guide on how to create tailored and unique frameworks for each case, check out our article on case interview frameworks .

Before you start developing your framework, it is completely acceptable to ask the interviewer for a few minutes so that you can collect your thoughts and think about the problem.

Once you have identified the major issues or areas that you need to explore, walk the interviewer through your framework. They may ask a few questions or provide some feedback.

3. Kick off the case

Once you have finished presenting your framework, you’ll start diving into different areas of your framework to begin solving the case. How this process will start depends on whether the case interview is candidate-led or interviewer-led.

If the case interview is a candidate-led case, you’ll be expected to propose what area of your framework to start investigating. So, propose an area and provide a reason for why you want to start with that area. There is generally no right or wrong area of your framework to pick first.

If the case interview is interviewer-led, the interviewer will tell you what area of the framework to start in or directly give you a question to answer.

4. Solve quantitative problems

Google case interviews typically have some quantitative aspect to them. For example, you may be asked to calculate a certain profitability or financial metric. You could also be asked to estimate the size of a particular market or to estimate a particular figure.

The key to solving quantitative problems is to lay out a structure or approach upfront with the interviewer before doing any math calculations. If you lay out and present your structure to solve the quantitative problem and the interviewer approves of it, the rest of the problem is just simple execution of math.

5. Answer qualitative questions

Google case interviews will also typically have qualitative aspects to them. You may be asked to brainstorm a list of potential ideas. You could also be asked to provide your opinion on a business issue or situation.

The key to answering qualitative questions is to structure your answer. When brainstorming a list of ideas, develop a structure to help you neatly categorize all of your ideas. When giving your opinion on a business issue or situation, provide a summary of your stance or position and then enumerate the reasons that support it.

6. Deliver a recommendation

In the last step of the Google case interview, you’ll present your recommendation and provide the major reasons that support it. You do not need to recap everything that you have done in the case, so focus on only summarizing the facts that are most important.

It is also good practice to include potential next steps that you would take if you had more time or data. These can be areas of your framework that you did not have time to explore or lingering questions that you do not have great answers for.

Google Case Interview Examples and Answers

Example #1:  What differences would you take into account when selling a product to a client in India versus a client in Argentina?

Sample solution: To answer this, create a framework that shows the most important characteristics or qualities of each country that you would want to look into. For example, one potential framework may look into the customer needs and preferences, the competitive landscape, market trends, and Google’s capabilities across the two countries.

Example #2:  If you were a Google Search competitor entering a new market and had a small market share, how would you convince advertisers to advertise with you?

Sample solution: To answer this question, you should be familiar with Google Search. You can create a framework that outlines the product’s strengths and weaknesses so that you can identify gaps in customer needs. 

At a high level, the strengths of Google Search is that it has the widest reach since it is the most used search engine. It also has high targeting specificity since it has lots of data on long-tail keywords. However, the main drawback is how competitive and expensive it can be for advertisers to use. Customer service can also be slow for smaller customers given the number of customers Google services. Finally, the product can be complicated for advertisers to set up initially.  Therefore, when entering a new market as a Google Search competitor, it may make sense to target customers with smaller budgets and sell them on low-prices, fast customer service, and ease of set up.

Example #3:  What are three areas that Google should invest in?

Sample solution: To answer this question, it may be helpful to clarify what Google’s primary objective is. Are they looking to increase profits, revenues, or number of users? The ideas that you brainstorm may vary depending on their actual goals.  Next, develop a framework to organize your ideas. You may want to think about areas of investments as short-term investments, medium-term investments, and long-term investments.

Example #4:  If you were the CEO of AdSense, what would be your strategy to improve the product?

Sample solution: As always, create a framework to help you organize your ideas in a clear and easy to follow way. To improve AdSense, you can think about improving the product for advertisers, improving the product for search users, and improving the product for Google’s profitability. Using a framework like this one will help you consider all of the different ways that AdSense can be improved.

Example #5:  How much money do you think YouTube makes daily from ads?

Sample solution: This is an estimation question. Before doing any math calculations, make sure to lay out a structure or approach for how you would estimate this figure. 

You may want to start by estimating the number of people in the world, the percentage that use YouTube, the percentage that use YouTube on any given day, the average amount of time spent on YouTube in a day, the number of ads seen for that period of time, and then estimating the amount YouTube earns per ad that is shown. Multiplying all of these figures will give you your answer.

Example #6:  How would you set the price for the YouTube masthead? The YouTube masthead is a digital billboard placed on YouTube’s homepage for 24 hours, reaching about 60 million people.

Sample solution: In general, there are three ways to price a product: pricing by the cost to produce the product, pricing by the economic value the product provides customers, and pricing by the price of competitors’ similar products.

Since the cost of putting up a digital billboard is minimal, the first pricing strategy is not helpful. Looking at the second pricing strategy, you can price the digital billboard based on how much it would have cost the potential customer to get 60 million ad impressions. Looking at the third pricing strategy, you can look into how much other types of advertising that reach a similar number of people costs. For example, you could look into how much Super Bowl ads cost.

Example #7:  How would you market the Google Ads product to a potential client?

Sample solution: To develop an effective marketing strategy, you may want to look into the client’s needs, competitor offerings, and Google Ads’ features or benefits. Exploring these three areas will help you identify the features or benefits of Google Ads that are superior to competitor products that the client values.

Example #8:  How would you estimate the market size of Google display ads on websites?

Sample solution: This is another estimation question. As always, outline a structure before you begin doing any math calculations. 

You may want to start by estimating the global population, estimating the percentage that have internet, estimate the average number of sites visited per day, estimate the percentage of websites that have ads, estimate the percentage of these websites that use Google display ads, estimate the revenue Google generates per ad. If you multiply the product of these figures by 365 days in a year, you’ll get an estimate of the market size of Google display ads.

Example #9:  How would you determine the number of staff members needed in the customer support team next year?

Sample solution: One potential approach for solving this question could look like the following. 

Start with Google’s annual revenues and estimate the average revenue generated per customer to determine the number of customers Google services. For each customer, estimate the frequency in which they call customer support and the average length of a support call. Assuming that a staff member works eight hours per day, you can estimate the number of staff members you’d need to meet the volume of support calls.

You may need to grow this number by Google’s historical growth rate to account for expected revenue growth next year.

Example #10:  If you were setting up a new ecommerce business, what are the things you would look at?

Sample solution: This is a market entry case. Potential areas you should consider looking into in your framework include: the attractiveness of the market, the competitive landscape, the company’s capabilities, and the expected profitability.

Example #11 : How should YouTube deal with spam?

Sample solution: There are many different ways to deal with spam. To ensure that you brainstorm ideas in a clear and comprehensive way, develop a framework to categorize all of the different ways of dealing with spam. You may want to think about this as: preventing spam from being posted, detecting spam, and removing spam.

Example #12 : Let’s say that Google is considering acquiring iRobot, a company that builds consumer robots, such as the Roomba. What would you consider when deciding whether to make this acquisition?

Sample solution: This is an acquisition case. To determine whether or not this is an attractive acquisition, you may want to look into: the attractiveness of the consumer robots market, the attractiveness of iRobot as a company, the potential synergies from the acquisition, and the financial implications of the acquisition.

Example #13 : Estimate the time it takes a Google Street View car to collect footage in a city.

Sample solution: To answer this question, first clarify which city the interviewer is talking about. Then, outline your approach for how you would do this calculation. 

You might want to start by estimating the length and width of the city area. Then, estimate how wide a street is and the average distance between streets. If you think of a city as a grid that consists of vertical and horizontal lines, you can use these estimates to calculate the total street length in the city.

Afterwards, estimate the average speed of a Google Street View car, taking into traffic and stoplights. Dividing the total street length by the average speed of a Google Street View car will get you an estimate of how long it would take to collect footage.

Example #14 : How would you define the strategy for YouTube over the next 5 years?

Sample solution: This question is very similar to Example #3. Before answering, it may be helpful to clarify what YouTube’s primary objective is. Are they looking to increase profits, increase number of users, or increase user engagement? You may want to think about strategy as short-term strategy and long-term strategy.

Example #15 : Let’s say that Google is considering getting into the ride share business. What should they consider when making the decision on whether or not to enter?

Sample solution: This is a market entry case and the approach is similar to Example #10. Potential areas you should consider looking into in your framework include: the attractiveness of the ride share market, the competitive landscape, the company’s capabilities, and the expected profitability.

Google Case Interview Tips

Below are eight of our best tips to help you perform your best during your Google case interviews.

1. Familiarize yourself with Google’s business model

If you don’t understand Google’s business model, it will be challenging for you to do well in their case interviews. Therefore, you should know that Google makes the majority of its revenue by selling advertising and you should be familiar with the products and services that Google offers for the specific team you are interviewing for.

2. Read recent news articles on Google

Often, the cases you’ll see in a Google case interview are real business issues that the company faces. Reading up on the latest news on Google will give you a sense of what Google’s biggest challenges are and what major business decisions they face today. There may be a good chance that you’ll be given a case that is similar to something that you have read in the news.

3. Verify the objective of the case 

Answering the wrong business problem will waste a lot of time during your Google case interview. Therefore, the most critical step of the case interview is to verify the objective of the case with the interviewer. Make sure that you understand what the primary business issue is and what overall question you are expected to answer at the end of the case.

4. Ask clarifying questions

Do not be afraid to ask questions. You will not be penalized for asking questions that are important and relevant to the case. 

Great questions to ask include asking for the definition of an unfamiliar term, asking questions that clarify the objective of the issue, and asking questions to strengthen your understanding of the business situation.

5. Do not use memorized frameworks

Interviewers can tell when you are using memorized frameworks from popular case interview prep books. Google values creativity and intellect. Therefore, make every effort to create a custom, tailored framework for each case that you get.

6. Always connect your answers to the case objective

Throughout the case, make sure you are connecting each of your answers back to the overall business problem or question. What implications does your answer have on the overall business problem?

Many candidates make the mistake of answering case questions correctly, but they don’t take the initiative to tie their answer back to the case objective.

7. Communicate clearly and concisely

In a Google case interview, it can be tempting to answer the interviewer’s question and then continue talking about related topics or ideas. However, you have a limited amount of time to solve a Google case, so it is best to keep your answers concise and to the point.

Answer the interviewer’s question, summarize how it impacts the case objective, and then move onto the next important issue or question.

8. Be enthusiastic

Google wants to hire candidates that love their job and will work hard. Displaying enthusiasm shows that you are passionate about working at Google. Having a high level of enthusiasm and energy also makes the interview more enjoyable for the interviewer. They’ll be more likely to have a positive impression of you.

Mastering Case Study Interview Questions for Business Analysts: Strategies for Success

Case study interview questions are a type of job interview where candidates are presented with a real or simulated business scenario or problem and are asked to analyze, assess, and propose solutions to the situation. These interviews are commonly used to evaluate a candidate’s problem-solving skills, critical thinking abilities, domain knowledge, communication skills, and how well they can apply their skills to real-world business challenges.

Case study interviews are a common component of the hiring process for business analysts. They aim to assess a candidate’s analytical thinking, problem-solving abilities, and decision-making skills in a real-world context.

Case studies for business analysts are scenarios or real-world problems that candidates are presented with during interviews to assess their analytical thinking, problem-solving skills, and ability to make informed decisions. These case studies are designed to simulate the types of challenges and situations that business analysts may encounter in their roles. Case study interviews are important for business analysts for several reasons:

1. Realistic Simulation: Case study interviews provide a realistic simulation of the kind of complex and multifaceted problems that business analysts encounter in their roles. They offer candidates a chance to demonstrate their ability to analyse, think critically, and make informed decisions based on incomplete or ambiguous information.

2. Problem-Solving Skills: Case studies test a candidate’s problem-solving skills. Business analysts often need to analyse various aspects of a problem, break it down into manageable components, identify root causes, and propose effective solutions. Case study interviews assess a candidate’s approach to tackling such challenges.

3. Analytical Thinking: Business analysts need strong analytical thinking skills to dissect problems, gather relevant information, and draw logical conclusions. Case study interviews assess a candidate’s ability to analyse data, identify trends, and make data-driven decisions.

4. Decision-Making: Business analysts often need to make decisions that impact an organization’s strategies, operations, and outcomes. Case study interviews evaluate a candidate’s decision-making skills under pressure and their ability to make well-reasoned choices.

5. Domain Knowledge: Case studies allow candidates to apply their domain knowledge to practical scenarios. This is particularly important for business analysts who work in specialized industries where understanding industry-specific nuances is critical.

6. Prioritization and Time Management: Business analysts  must manage multiple tasks and prioritize their workload. Case study interviews can assess a candidate’s ability to manage time effectively and prioritize tasks based on their significance and urgency.

Overall, case study interviews provide a comprehensive and practical assessment of a candidate’s capabilities as a business analyst, offering valuable insights into their analytical thinking, problem-solving skills, domain expertise, and ability to thrive in challenging work environments.

Sample Case Study Interview Questions

Candidates must use their creativity, analytical thinking, data interpretation, and industry expertise in order to succeed in these interviews. It is crucial for candidates to explain the rationale behind their decisions in addition to how they arrived at their recommendations. Success in case study interviews for business analysts depends on thorough understanding of business principles, effective communication, and structured problem-solving. Following are few sample case studies to help candidates understand the nature of these interviews as well as how to approach such questions.

Case 1: Market Entry Strategy

Company X, a technology firm, is considering entering a new international market. They want to tap into a growing economy with a strong demand for their products. You have been asked to recommend the most suitable market entry strategy. Consider factors like market size, competition, and regulatory environment.

Question 1: What is the primary factor that Company X should consider when selecting a market entry strategy for the new international market?

A) Company’s financial resources

B) Cultural diversity of the target market

C) Strong demand for products in the market

D) Political stability of the target country

Answer: C) Strong demand for products in the market

Explanation: The key consideration for entering a new market is whether there’s a demand for the company’s products. While other factors are important, such as financial resources and political stability, the fact that the market has a strong demand for the products makes it a primary factor in the decision-making process.

Question 2: Company X wants to minimize its risk exposure in the new market while still capitalizing on the strong demand. Which market entry strategy is most suitable for this scenario?

A) Exporting

B) Joint Venture

C) Direct Investment

D) Franchising

Answer: A) Exporting

Explanation: Exporting allows Company X to enter the market with relatively lower risk and investment. It involves selling products from the home country to the target market, which minimizes the need for significant upfront investments like direct investments or joint ventures.

Question 3: Company X values local expertise and distribution network in the new market. Which market entry strategy aligns with this preference?

B) Licensing

C) Joint Venture

D) Direct Investment

Answer: C) Joint Venture

Explanation: Joint Venture involves partnering with a local company, which brings local expertise and an established distribution network. This strategy allows Company X to leverage the partner’s knowledge of the market while sharing the risks and rewards.

Question 4: In terms of regulatory environment, which market entry strategy provides Company X with the most control over its operations in the new market?

A) Franchising

C) Exporting

Answer: D) Direct Investment

Explanation: Direct Investment, such as setting up subsidiaries or wholly-owned subsidiaries, provides Company X with the highest level of control over its operations in the new market. This strategy allows them to make decisions independently and tailor their operations to local conditions.

Question 5: Company X has limited financial resources. Which market entry strategy is the most cost-effective way to tap into the strong demand in the new market?

A) Direct Investment

D) Joint Venture

Answer: C) Exporting

Explanation: Exporting typically requires lower upfront investment compared to strategies like direct investment or joint venture. It allows Company X to leverage its existing resources to reach the new market and capitalize on the demand without significant financial risk.

Case 2: Process Optimization

Company Y, a manufacturing company, is experiencing delays in its production process. These delays are impacting customer satisfaction and profitability. Your task is to identify the bottlenecks in the process, suggest improvements, and estimate potential cost savings.

Question 1: Which of the following best defines a bottleneck in a manufacturing process?

A) A point in the process with excess capacity

B) A step that operates at maximum efficiency

C) A point in the process that slows down overall production

D) A step that requires minimal resources

Answer: C) A point in the process that slows down overall production

Explanation: A bottleneck is a point in the process that restricts the flow of production and slows down the overall process. It is the part of the process that has the lowest capacity or efficiency, causing delays.

Question 2: Company Y identifies a bottleneck in the assembly line where workers are frequently waiting for parts. What improvement strategy should they focus on?

A) Increasing the number of workers in the assembly line

B) Streamlining the production process to eliminate non-value-added steps

C) Reducing the number of parts used in assembly

D) Increasing the amount of inventory for parts

Answer: B) Streamlining the production process to eliminate non-value-added steps

Explanation: Eliminating non-value-added steps and improving the flow of materials can help reduce wait times and alleviate the bottleneck. Increasing the number of workers or increasing inventory might not address the root cause of the issue.

Question 3: What is the purpose of conducting a root cause analysis in process optimization?

A) To identify all steps in the process

B) To assign blame for process delays

C) To identify underlying causes of process inefficiencies

D) To increase the number of process steps

Answer: C) To identify underlying causes of process inefficiencies

Explanation: Root cause analysis is conducted to identify the underlying factors that contribute to process inefficiencies or delays. It helps to pinpoint the true causes of problems rather than just addressing symptoms.

Question 4: In the context of process optimization, what is the “Theory of Constraints” (TOC)?

A) A method for increasing the number of process steps

B) A strategy to eliminate all bottlenecks in a process

C) An approach to identifying and managing constraints that limit process performance

D) A technique to maximize inventory levels

Answer: C) An approach to identifying and managing constraints that limit process performance

Explanation: The Theory of Constraints (TOC) is a management philosophy that focuses on identifying and managing constraints or bottlenecks in a process to improve overall performance. It aims to optimize the flow of work through the entire system.

Question 5: Company Y implements process improvements that reduce production time per unit by 20%. If they produce 1,000 units per month and each unit generates $50 in profit, what is the estimated monthly cost savings?

Answer: C) $10,000

Explanation: If each unit generates $50 in profit, a 20% reduction in production time per unit would result in a savings of 20% * $50 = $10 per unit. With 1,000 units produced per month, the total estimated monthly cost savings would be 1,000 units * $10 = $10,000.

Data analyst interview - case study

So i have an interview in twe weeks for this job that i am very interested on “data analyst” and i was told to come up with any personal project to present during the interview. Anyone have any idea or video that i can watch and practice a project as simple as possible.

I have completed 3 courses of the google data analytics certificate and I know that last course is a case study but reading about it, it seems very difficult and needs longer time and i don’t think i can complete this certificate in only two weeks.
