Today I’m gonna show you a curated list of the 9 VERY BEST Case Interview Example videos from all around the web.
Why?
So you don’t have to go through the same pains I did back when I was preparing:
- I watched TONS of videos on YouTube, but most of my time was WASTED because many weren’t helpful at all.
- I couldn’t tell which cases were realistic and which were unrealistic, or which were hard and which were easy.
- I couldn’t even tell whether each answer by the candidates was good enough to pass the interview or not (my best proxy was their confidence, which I later found was NOT a good proxy).
So that brings us to this article.
What's in for you:
Every hour you spend on the examples in this article is the equivalent of spending 3-5 hours browsing YouTube on your own, reading Case in Point, or going through piles of casebooks.
This article is the result of...
24 of those videos didn’t make it to the list: they were a mix of poorly recorded, unrealistic and even misleading.
I curated just the best so you wouldn’t have to waste your own 20+ hours to find them.
- #1. Playworks market entry [Best for beginners]
- #2. Recreational marijuana market entry [Easy case, unusual industry]
- #3. A+ Airlines’ reaction to competitor’s change
- #4. Auto manufacturer profitability decrease [Best profitability case]
- #5. Swift fox population decrease
- #6. Bed and Bath e-commerce acquisition [Best for solo practice]
- #7. FlashFash acquires LaMode
- #8. Metrocity waste management [Best public sector case]
- #9. Pepsi’s LA bottling plant
(And here are some bonus cases that weren’t good enough to make it to the list, but still had something special that might be interesting to you.)
- #10. Cutie Co.’s profitability decrease [Great only for beginners]
- #11. 1930’s gangster growth strategy
#1. Playworks market entry
VIDEO
- Easy case, with one Estimation, one Quantitative Analysis, and one Chart Interpretation questions within. Overall, good to practice and to get a feel for case interview dynamics
- You can’t see the Exhibit the candidate is shown, but you can find it in this link provided by Yale SOM Consulting Club (go to page 9)
CANDIDATE’S PERFORMANCE
- Stellar framework, touching on all relevant issues and showing a plan to solve the problem from beginning to end
- Great job performing a spontaneous reality check to his estimation
- I would expect more reasoning behind some of the key assumptions (# of high schools and colleges in the US). He was, however, close to the real values – his background as a teacher could have played a role, but as an interviewer I would still have needed to see his reasoning behind those numbers
- Big mistake inadvertently converting square yards to square feet (~10x difference in final answer) combined with math confusion within the Estimation and inefficiencies in Analysis: his analytical skills would have to be tested more thoroughly in a third interview or in a next round
The next case is mostly useful for its framework question.
It’s a good question to practice because it’s an easy question in an unusual industry.
(I bet you haven’t seen a case on recreational marijuana yet.)
It also has one easy Chart Interpretation question, which is not frequent on case interview examples you see out there.
But… It doesn’t go much further.
The candidate’s answer to the Framework question is below OK, and his answers to the Chart Interpretation questions are also not good.
But at least you can use the case to practice on your own if you know what elements your answers should have.
#2. Recreational marijuana market entry
VIDEO
- Not a hard case, but I’d say it’s realistic for an easy first round case at MBB
- There are some spontaneous brainstorming questions within the case (e.g. 5:54) – few case examples have these, and nearly all real interviews do
- The exhibit is shown for a short period of time at 4:10
CANDIDATE’S PERFORMANCE
- This candidate missed a few insightful issues in the initial structure, which would have made it a great answer – here they are:
- “Would we be able to use our current facilities to provide for that country and just export?”
- “Benchmark for all these questions and metrics in other potential countries”
- “What is the market size in target country?”
- He did not lead the case at all from the insights he got after reading the chart
There’s another problem in this candidate’s answer that you should know.
This one deserves more space, that’s why it’s down here and not in the comment box.
The first thing the candidate said he would want to look at is the “political/economical/social/technological/environmental and legal situation” of the country.
I want to challenge you to ask yourself the questions the manager and the partner of that project would be asking themselves if a business analyst proposed that in a real consulting project.
- What’s the scope of those analyses?
- What specifically does he want to know?
- How long is that going to take?
For the political situation of a given country, you could have political scientists write a dozen books and still not be exhaustive. How does he plan to fit that into the project?
It’s clear that he doesn’t want that level of depth, but what DOES he want to know?
So… what should Robin have said to justify that part of his framework?
Answer: Whatever he thought he could find that would actually change the course of the client’s decision.
Here’s an example:
“I just want to make sure that there’s no chance that the country will suddenly prohibit recreational marijuana again, or that the rules will change and they’ll allow only for local companies to grow and sell.”

Now to the next video…
Yale SOM Consulting Club and Elaine Dang deserve congratulations on the two videos they made.
It’s super high quality work.
Both of their video examples are similar to real case interviews in format and content, and they’re even superior to some made by case interview prep websites.
#3. A+ Airlines' reaction to competitor's change
VIDEO
- Questions and difficulty realistic for McKinsey, Bain, or BCG
- A real case might have more Brainstorming questions within the case
- Negative: you can’t se the exhibits the candidate is shown
CANDIDATE’S PERFORMANCE
- Great: all of her answers were backed by at least one layer of structure
- Insights provided after calculating every new number, which is super important (learn more)
- She did a good job keeping the interviewer on board by doing her math out loud at all times
- One thing she could’ve done better was to not constantly come back to the “cash tied up in the cash box” idea – she should’ve tested it once and definitively as to whether that is relevant or not (it isn’t) – a partner would have certainly challenged her on that
Featuring next: me reviewing my own video from a neutral point of view.
Yes, I know that can’t possibly be unbiased.
But here’s why I think this video will get you ahead of other candidates and why you should ABSOLUTELY NOT miss out on this:
- The case comes nearly straight from my own Bain final round.
- My question in the end is difficult (even for McKinsey, Bain or BCG’s standards), and Bruno’s answer is impressive.
- Bruno’s solution is not perfect, and this gives us both an opportunity to openly discuss how it could’ve been better by the end.
#4. Auto manufacturer profitability decrease
VIDEO
- Average-difficulty profitability case in the first half, and a difficult question at 15:44
- Full realistic drill-down to find the real root cause of the problem, which is a common thing in case interviews that you’ll only find in this video
CANDIDATE’S PERFORMANCE
- Bruno should have presented his answer as a plan before diving into the profit tree, which is an advanced skill that makes you sound more like a consultant and less like a candidate
- Efficient and organized drill-down in the profit tree, a must-master habit for all candidates
- Super insightful answer to the second question because it shows second-order level thinking
If you’re mainly looking to improve your performance in profitability cases, there are two pieces of content worth checking out:
- And this article, the state-of-the-art in profitability trees: Profitability Trees: The Complete Guide
What I love about the next case is that the first question is on diagnosing a client’s issue, but it’s not a profitability case.
It’s actually a public sector case!
Most beginners think you only use issue trees and drill-down analysis when solving a profit problem, but as you’ll see in this case, this is not true at all.
The candidate’s answer is good, so you can compare your own answer to his.
BUT… You can’t see the exhibits the candidate gets at 8:40.
They’re critical for everything that follows, so the case is basically over there if you’re trying to get some practice.
If you’re looking to get some practice on chart reading specifically, this video won’t do it for you.
#5. Swift fox population decrease
VIDEO
- This is a difficult, realistic diagnostics case, great for advanced candidates to step up their practice with hard cases
- You are not shown a critical exhibit the candidate gets in the middle of the case, making it unsuitable for practice from then on
CANDIDATE’S PERFORMANCE
- The candidate’s initial structure is insightful because it breaks down the population problem into its key drivers
- You can’t really tell whether his insights regarding the exhibits were good or not because you can’t see the exhibits, but I would expect next-steps after the conclusions (e.g. after 10:03, he could have said “And to figure out whether this really is the cause of the population decrease, the next thing I would do is…”)
- But he doesn’t make the same mistake twice – at 22:50, he gets to a number the interviewer asked and, this time, he leads the case perfectly: he comes up with a conclusion (the insight), and then proactively leads the case with next steps
The next video is THE SINGLE BEST in this list for solo practice.
You will see Bruno’s reaction to challenges most people only face in their actual interviews. Mock interviews hardly prepare you for this at all:
- How should you react when an interviewer asks you for more ideas after you’ve given everything you have?
- What do you do when your interviewer asks for a recommendation having given you nearly no data?
Go ahead and see for yourself.
(And how would a real candidate do in this case? I interviewed a candidate with this very same case and recorded it so you could see for yourself.)
#6. Bed and Bath e-commerce acquisition
VIDEO
- Pay special attention to how I made spontaneous challenges to Bruno after his answers. Most mock interviews, even with consultants, don’t have that. So candidates end up getting surprised by them in their actual interviews. You might even want to show this to your peers so they’ll do more realistic mock interviews with you
- In 9:00 I challenge Bruno to see if he’s sure whether customer loyalty was good (higher customer lifetime value) or bad (harder to increase market share) for the acquisition
- In 16:22 I challenge Bruno to find even more ideas other than the ones he had already given
- Due to being interviewer-led AND having great benchmark answers, this is the best video in this list for solo practice
CANDIDATE’S PERFORMANCE
- Super structured brainstorming, which showed me he would not leave any important area behind and helped him give me a ton of creative, insightful ideas
- Insightful framework answer (e.g., 99% of candidates would not talk about whether running this business would be attractive to the friend, much less in depth like he did)
The next case is one of the unmissable videos in this list for two main reasons.
Number one, the candidate’s answers are great, good enough to be benchmarks to your own.
Number two, it’s a difficult M&A case (which is not as exciting as watching the last Avengers movie, I get, but still…).
#7. FlashFash acquires LaMode
- Realistic, challenging interviewer-led case for McKinsey, Bain and even BCG (as some interviewers there have been doing this type of case recently)
- Quality answers make it great for solo practice
CANDIDATE’S PERFORMANCE
- Insightful, well-built framework, definitely a benchmark
- Notice how the candidate shows his structure for the quantitative analysis before diving into the math – that’s a great habit you definitely want to copy
What I love about difficult cases is that they always allow for creative structures and ideas.
The case I’m gonna show you next is one of my absolute favorites because it’s a tough public sector case.
It’s a shame it didn’t get more views on YouTube.
If you’re serious about your case practice, I highly recommend you spend as long as you need to structure that case as deeply as you can, as that’ll help you build your structuring skills.
Don’t be surprised if your answers are more structured than hers – actually, that’s what you should be aiming for.
#8. Metrocity waste management
VIDEO
- This case is difficult and unusual because of its case question, and super realistic due to the natural follow-up questions asked by the interviewer
- It’s a great case to practice if you’re an advanced student – just remember that your answer can (and should) go deeper than hers
CANDIDATE’S PERFORMANCE
- Although she had a good structure and good ideas, she could have gone deeper, and definitely could have had more creative ideas, such as finding different destinations to waste (incineration, composting), or compressing the waste inside the landfill from time to time
If you want to learn how to be more creative in case interviews, check out this golden article Bruno recently wrote about that topic.
(If you’re gonna click that, brace yourself: it’s a full 5,971-word article with 11 highly actionable tips to help you be creative in your case interviews.)
The next video shows an operations case example.
It’s a wonderful use of process structures to diagnose an issue on production line.
I don’t really like its style for practicing for two main reasons.
First, it just doesn’t have the right tempo for you to pause and practice and then compare answers.
Second, the comments in the middle break the flow.
Nothing wrong with those comments. They’re actually helpful.
The problem is they make this video good for learning a few new concepts, watching a good structure put to use, but not really to practice by yourself.
If you’re an advanced candidate and your practice is up to date and you’re just looking to learn something new, jump right in.
#9. Pepsi's LA bottling plant
VIDEO
- Only one person playing the interviewer’s and the candidate’s roles, which doesn’t give you an idea of how the case would flow
- Difficult case, great case for advanced candidates to increase their experience/library
- Not really tailored for you to pause and solve at each moment, doesn’t have a good tempo for that
CANDIDATE’S PERFORMANCE
- “Candidate’s” structure at 5:34 is a great example of a process structure put to use in diagnostics cases
- Super insightful brainstorming at 14:50, with at least one idea you most likely wouldn’t think of
Want to learn to solve cases like the best interviewees in these videos?
Here’s the deal: you can watch as many of these great videos as you want, but they will only help you up to a point.
They’ll help you understand what a case interview is like…
And if you try to answer the questions as you watch them, these videos will even help you get some practice…
But examples of case interviews will never teach you HOW to do cases well.
And if you want to be outstanding at solving cases so that firms like McKinsey, Bain, or BCG are begging you to accept their offers, we have something for you!
We’ve created a free course that will teach you EXACTLY HOW to answer the 6 (and only six!) types of questions you will find in ANY case interview.
(You can even go back to ALL the questions asked within the 9 examples of this article… You’ll see that each of them can be answered using one of the six techniques.)

Now, you might be asking yourself: is this even worth my time?
I get that! There’s so much content out there, and so little time to practice.
Well, here’s the kind of e-mail we get from candidates all the time… It speaks for itself:
Bonus videos!
In the beginning of this article, I told you there’d be a couple of videos by the end that didn’t make it to the list.
They’re not that good to make it to a “best of” list.
Still, I want to add them as bonuses each of them will add value to you in their own way.
#10. Cutie Co.'s profitability decrease
You should ONLY watch this case if you have never done a mock interview before.
Here’s what’s great about it… The interviewer breaks down the specifics of how the candidate should speak and act in the interview.
(Down to the choice of words.)
It is also an easy case, which makes it easy to understand.
VIDEO
- This is a super easy case and its real value is less in the case itself and more in the back and forth discussion of how the candidate should communicate
- I wish it went further into the problem drill-down, to show the interactions between candidate and interviewer in a profitability case
CANDIDATE’S PERFORMANCE
- The goal of this video is to show slight communication tweaks rookies often skip, not to serve as a performance benchmark – I’d rather not comment on how well he did
#11. 1930's gangster growth strategy
Do NOT watch it without reading the comments.
Sometimes the greatest lessons come from mistakes. This is one of those times.
There’s a comment in the video in which the interviewer suggests that a necessary step in every case is “getting to” a chart.
This gives candidates two false impressions:
False Impression #1) There is a chart in every case, and your goal as a candidate it to “get to it”.
False Impression #2) If your interviewer has given you all the charts they had, you’ve done a good job!
Your goal as a consultant is to find the relevant hypotheses to solve the problem in a structured way and to test them with data.
If you do that, you will have done a great job, and your interviewer may or may not have given you a chart along the way.
This is true for interviews and the consulting job alike!
VIDEO
- Interesting case, as it’s a growth strategy in an unusual “industry”
- It is one of the few cases available online that let you practice Chart Interpretation questions, a common type at McKinsey, Bain and BCG
- Unfortunately, it gives the impression that “getting to all the charts” is the overarching goal of solving a case
CANDIDATE’S PERFORMANCE
- In the first Chart Interpretation question, the candidate missed a critical insight: that they already have 100% market share in all markets. While the interviewer downplays it, it was a big foul that would be hard to recover from in a real interview
- The candidate provided insight after reading each exhibit – good job. However, he’d never proactively give clear next steps, which is what a well-prepared candidate would do
- If you’re practicing by yourself, remember not to use this candidate’s answers as a quality benchmark
And now it's your turn!
Are there any videos in this list that you think shouldn’t be here?
Or that you think SHOULD BE and aren’t?
I’d also love to know if there are any types of case interview examples that you were looking for and didn’t find anywhere. We may even make one just for you.
Let me know in the comments. I’ll read and respond to each and every one of them.
Marco Antonio da Silva Junior
Hello guys,
In the third case, about the marijuana market entry, I saw that the candidate was kind of lost in the maths when trying to calculate the market share needed to get the return on the initial investment. I tried to solve the case by myself but actually got a bit lost too in this part. Do you know what’s the best alternativa to solve a problem like that?
Thank you very much,
Marco
Bruno Nogueira
Practice break-even analyses done from different angles Marco! It could be break-even on units to be profitable, a break-even on market share to return investment in X amount of time or any other variables you can think of!
Adam H
I played along with this case and took a different / simplified approach which led me to the 6% market share number…
1. Add up the base market sizes over years 2017-2021 to get the total market size over the investment period ≈ 1100MM.
2. Multiply by the predicted revenue margin and compare to the investment. 1100MM * 30% * (Market Share Needed) = 20MM.
3. Market Share Needed ≈ 6%
In reality, this is all very simplified, and a lot of the fun calculations were already made for you. In longer case interviews I’d hope to be asked to calculate these things. Also not mentioned was the spike in market potential between 2017-2018, which would suggest that the candidate recommend front-loading investment, and providing a recommendation to capture the market earlier while it is growing faster.
Would have loved to see some critical thinking about how the market sizing was generated by the mysterious producer of that graph 🙂 Did they extrapolate from number of marijuana possession misdemeanors vs. population, or recreational alcohol usage, or perhaps baseline against countries with legalized recreational marijuana with similar demographic makeups?

Hi,
You guys are awesome, you actually brought together all my favorite videos available online except for one. And if you don’t mind I just wanted to share it here for your consideration:
https://www.firmsconsulting.com/complimentary-videos/mckinsey-final-round-partner-case-interview/
Thanks for the fantastic job you are doing.
Bruno Nogueira
It is indeed a pretty good video! Thanks for that!
Also, super glad that we were able to to do a good job curating the best videos in your experience too 🙂
Leno
Interesting, but to be honest, her performance is absolutely disastrous. Hard to believe she received a McK Offer 30 days later. She must have improved by sooooooooooo much 🙂
Mona
Hi,
Thank you very much for the videos and the comments on them.
Could you please explain how he calculated the market share the company need to capture in order to break-even in the marijuana case study?
Thank you,
Mona
Adam H
Excellent work here, as you mentioned there are a LOT of junk case interview videos and you found some great ones!
Bruno Nogueira
Super glad that was a helpful curation!
Olasunkanmi
Hello Guys,
In the third case about the marijuana market entry, I couldn’t figure out why the market share the candidate gave was 5% and the interviewer said the right was 6%. In my calculation it was about 10% market share to breakeven. Below is how I got it.
Looking at the exhibit the total market size in the fifth year is $310 million dollars and given the discount rate of 10%, the present value of $310 million would yield $192.5 million using Future Value = Present Value (1+ Discount Rate)^years.
Since Green Co wants to break even and is asking about the market share. I decided that X% market share * Total market size should yield a total of the investment to break even.
X%* $192.5 million = $20million. Solving for X it would yield a market share of approximately 10%.
Please can you point out where I am wrong, If I am?
Thanks,
Olasunkanmi
Bruno Nogueira
Hey Olasunkanmi,
I haven’t gone through the case myself (Julio has I think), but check out Adam’s reply here as you might find your answer there!
Cheers,
Bruno
Leno
I think Adam did not take the discount rate into consideration. I also came to the same conclusion as you did.
Jyo
Another good case here: https://www.youtube.com/watch?v=-5SVIJUELkg

Hi guys,
Great collection, thanks!
I find case 10 particularly interesting (although it’s pretty mundane), the initial framework breakdown, as well as the interviewer comments.
The first instinct is to break it down to (slightly) more advance profitability tree, something like contribution margin minus fixed cost. If you continue with different products in the contribution margin tree you can get a nice direct view on the selling price, direct labor, direct materials, and the number of products sold. It would be very easy to spot if it is product mix problem or/and pricing problem.
However, you might not find the root cause.
On the other hand, if your choose more qualitative framework such as internal/external you can ask more open questions e.g., industry trend (decline?), competitors, raw materials, and even bad publicity or economic shock.
I’d be interested to hear what approach you will choose?
Cheers.
Kestrel
Hi guys! Quick question about the level of difficulty for the cases. Are the advanced cases more catered to postgrads/MBA candidates? I just finished my undergrad and was wondering about the difficulty of cases I might expect. Should I be expecting more Beginner level cases? I’m prepping for both just in case. Thanks for the great material!
Bruno Nogueira
Hi Kestrel,
Case difficulty doesn’t change much. They do easy and challenging cases with undergrads, interns, MBAs, experienced professionals, all the way up to when interviewing potential partners.
The expectation of how much business sense, etc. you have might change slightly, but the problem solving not so much. (Not enough to change the way you should prepare at least)
