How to Use Case Interview Examples to Ace Your Case
1. Start Your Case Interview Preparation Early.
You’ll need to practice dozens of case interview examples to get good enough to receive an offer from one of the top consulting firms. This is not something you can cram the night before an interview.
Start as soon as possible.
2. Don’t Read Straight through Sample Case Interview Examples or Passively Watch Videos.
Some people think that the best way to improve their chances of passing a case interview is by reading as many cases interview examples as they can.
This is like reading about how to play tennis but never picking up a racket. To get better at tennis, for example, you need to actually pick up a ball and be active. The same applies to your interview preparation.
Stop and think at each step in the case interview question. Come up with your own answer and say it out loud. Practice driving each part of the case interview example yourself.
- How would you structure your analysis of the problem?
- What questions would you ask the interviewer?
- How would you set up the case math problem?
- What recommendation would you make to the client?
After you’ve developed your answer, compare it to the suggested answer for the case.
What did you get right?
How did your answer and the case interview example answer differ?
Are there things you miss consistently across multiple case interview examples?
The answers to these case interview examples can look simple when you just read through them, but it’s not easy to come up with all the key aspects of the solution on your own.

3. Find Partners to Practice Case Interviews with.
Teamwork is an important part of consulting work, so get ready for it now. Find a case interview practice partner, preferably someone else who’s applying to jobs in the management consulting industry because they’ll know more about what recruiters are looking for.
Practicing cases with a partner provides the opportunity to get feedback from someone else on what you’re doing well and what you need to improve. Additionally, you’ll learn a lot by watching how your partner solves sample case studies.
Look for aspects of their approach that are effective as well as what they could do better. Working with a partner will make your consulting interview practice feel more real.
Similar to how you need a tennis partner to feel what is like to play tennis, you need a case partner to experience what a case interview is like.
4. Master the 4 Parts of the Case Interview.
In our article on Case Interview Prep, we discussed the 4 parts of the case interview: the opening, structure, analysis, and conclusion. As you practice with consulting case interview examples, practice each of these 4 parts to ensure you’re strong at them all.
5. Avoid Case Burnout.
You were drawn to consulting as a career because you loved the idea of solving complex business problems with smart, passionate teammates. But one thing that can happen as you spend hours practicing how to answer case interview examples is that it can practice too much and become a case interview zombie.
A case zombie is someone who’s grown tired of casing from doing too much of it. Their answers feel rehearsed, not conversational.
They may seem bored, not engaged in solving the problem. They’ll be less creative in their solutions. They certainly won’t pass the airport test!
Avoid becoming a case zombie by practicing smarter, not harder.
Video: Case Interview Examples – Questions & Answers
In the following case interview example, Davis Nguyen, founder of My Consulting Offer, talks with Dan, an MCO coach and former BCG consultant and interviewer. Their discussion of BCG’s GenCo case is broken into 4 parts of the case interview.
In their case interview example, Davis and Dan demonstrate how to approach the business problem. They also provide examples of good answers vs. exceptional answers. Take note of what differentiates a good case interview answer from an exceptional answer so that you can not only get through your interview, but ace it.
Remember, don’t just watch the video. Stop the video and provide your own answer before listening to Dan’s answer to the case question.
Step 1: Case Interview Example Opening – Ensure you understand the client and the problem you’ll be solving in the case.
Step 2: Case Interview Example Structure – Break the problem down into smaller parts. Make sure you cover all key case issues.
Step 3: Case Interview Example Analysis – Ask questions, gathering information from graphs and charts provided by the interviewer, do case math, and provide insight into the client’s business problem based on what you learn.
Step 4: Case Interview Example Recommendation – Develop a rational recommendation for the client based on all you’ve learned throughout the case interview.
Tips for Acing Your Consulting Case Interviews – The Difference Between Average & Exceptional
Case Interview Opening
The opening is a great point to ask “dumb” questions because, at this point, you’re not expected to know much about the client and their business.
Here your goal is to understand the client, their business, and what a successful project will look like.
Don’t shy away from asking for clarification on things that will help you better understand the business problem and solve it. For example, if you don’t know how life insurance works and the case is about life insurance, then ask.
After ensuring you understand the client and their problem, the next thing to ask about is key metrics of success.
For example, the client may want to find new avenues for growth. Are they looking for a 5% increase in revenue or to double their business?
Finding out what success looks like in the client’s eyes will ensure you work to deliver a solution that meets their expectations, not one that’s underwhelming.
After you find out what success looks like, ask further probing questions to better understand the client, their business, and any constraints on solving the case.
Examples of Relevant Questions to ask Your Interviewer
Examples of relevant questions about the client might include the geography they operate in or the sector of their industry they are strongest in.
Examples of relevant questions about their business might include what products or services are most profitable or most important to their customers.
Examples of relevant questions about the problem might include whether there are any costs that can’t be cut or what the maximum amount the client is able to invest in developing a new product.
Asking these types of questions up front will give you a better context for solving the client’s problem and make it more likely that you will solve the case interview.
Case Interview Structure
You’ll need a framework to make sure your analysis covers all key aspects of the consulting case.
You can use one of the many standard Case Interview Frameworks we’ve outlined, but top interviewees develop their own framework for analyzing the case interview question.
Their frameworks may include pieces of one or more of the standard frameworks but are tailored to the particular business problem they’re discussing.
Good frameworks are hypothesis-driven, that is to say they can be tested similar to the science experiment, so that the answer is either a “yes” or “no.” For example, examining your bank account to see, “if I have $400 for a ticket” is an example.
Second, good frameworks cover all topics relevant to the answer. For example, if the client is opening up a new hotel in a foreign country, checking out the existing competition should be part of the framework.
As you study more about interactive case interviews and practice them you’ll develop a sense for what factors are relevant or not relevant to the case at hand.
Finally, a good structure will be MECE or mutually exclusive and collectively exhaustive.
This means the framework will break down the market or population being analyzed into segments that include every part of the whole (collectively exhaustive), and each segment of the market or member of the population will show up in one and only one category without overlap (mutually exclusive).
For example, if you divide the target market for a retail product into segments by age, these segments would be MECE:
- 40-49, etc.
The categories 15-25, 20-30, 27-35 would not be MECE because people could be counted twice.
Case Interview Analysis
In the analysis phase of your case interview example, you’ll ask questions to get the information you need to solve the client’s business problem. Your questions will likely lead you to one of the 4 types of analysis that are common in consulting interviews: market sizing, brainstorming, quantitative reasoning (case math), or reading exhibits.
No matter which of these types of analysis comes up, there’s a 4-step method that ensures you can crack the case.
This 4-step method is:
- Ask for data,
- Interpret the data,
- Provide insight, and
- Outline next steps.
The data you ask for will depend on the case interview question you’re solving. For example, if the question is about profitability, you’ll need to know about the client’s finances: dig into revenues and costs.
Once you have the data, you need to interpret it. What does it mean with regard to the problem you’re trying to solve?
For example, if you find that the client’s revenues are flat while their costs have been rising, you’ll know that the problem is in the cost structure and that you’ll need to examine costs more closely.
Next, provide insight. As you examine costs further, you’ll find out why they’ve grown faster than revenues.
This insight will naturally lead to the next steps. What does the client need to do to get costs under control and fix their profitability problem?
You may need to go through this 4-step method a couple of times, focusing on different aspects of the client’s business problem.
Once you’ve examined and developed insight into all key aspects of the problem, your next step will be to conclude the interview with a recommendation for the client.
Case Interview Conclusion
At this point, you’ve hopefully cracked the case and are ready to present your recommendations to the client (your interviewer).
The best way to do this is to use the 5R approach:
- Recap – restate the business problem you’ve analyzed. In consulting this is done because a CEO might have hired 5 McKinsey teams and can’t remember which one you are on.
- Recommendations – Provide the solution your analysis led to. We lead with the recommendation because it is the most important piece of information. Stating it first and clearly puts everyone on the same page.
- Reasons – Summarize the key facts and insights that lead you to your recommendations.
- Risks – Outline any risks the client should be aware of as they implement your recommendations. No recommendation has a 100% probability of success. Clients need to be aware of business risks in the same way patients need to understand the side effects of drugs.
- Retaining the client – Provide next steps for how you can help the client ensure success. As consultants, we are paid for helping our clients. If there is a natural extension of the work as the client implements the team’s recommendations, we should tell them how we can provide further assistance (and ultimately make money for your firm).
While most candidates will address their recommendations and possibly the reasons for their recommendations, few will hit all these points.
In particular, outlining risks and further ways you can help the client will differentiate you from other candidates and help you to advance to the second round of interviews or get the offer.
