Inquiries about interviewer-led case interviews

Question

Hi, there!

I've been checking out different resources for interviewer-led case interviews, but they all seem to suggest different things. The more I look into it, the more confused I get. How do I figure out which approach is the best for tackling an interviewer-led case interview when everyone's saying something different?
So, I've been reading up on interviewer-led cases, and there's this whole thing about hypotheses. Some say you should come up with them right off the bat when you get the case, while others say to keep them to yourself. What's the deal? Can someone break it down for me? I get the concept of hypothesis, but I'm not sure how it fits into a case interview

Cheers!

Hi there,

Two major things for you:

First: Get a coach - it changes everything

Second: Read this article - Candidate-Led Cases: What to Expect With Example Cases

I've been checking out different resources for interviewer-led case interviews, but they all seem to suggest different things. The more I look into it, the more confused I get. How do I figure out which approach is the best for tackling an interviewer-led case interview when everyone's saying something different?

It sounds crazy but 80% of material out there just isn't good. Unfortunate but true. Partly because it's a hard topic to explain in writing, and partly because oversimplification sells.

Ultimately, “which approach” isn't the right way to think about this. Remember that you are training to be a consultant. This is a simulation of a consulting project. Just like there isn't just a “single approach to solving the business world's problems”, there won't be one here.

It's more complicated than that and can't just be answered in a few sentences….

How to Shift Your Mindset to Ace the Case

Kind of.

Careful with hypotheses.

Don't worry about them right now because people do them terribly wrong (e.g. they "guess).

Hypotheses come later. Get to 20-30 cases under your belt and 3-5 coaching sessions with a case coach.

Then come back to worrying about hypotheses.

The Most Common Pitfalls in Case Interview Preparation

Answer 2

What a cool question!

If you approach cases in the right way, there is no difference between candidate led and interviewer led cases.

Why?

Because regardless of the format, you as the candidate should be the one leading the case forward, building and sharing your thinking framework and then suggesting next steps.

The difference is that in actual interviewer-led cases, the interviewer will steer the cases in the direction they desire regardless of what you suggest. Even so, it's still best to signal that you know how to take the case forward.

In candidate led, the interviewer will steer a lot less and let you go in the direction you suggest. You have more autonomy, but this also comes with more responsibility.

Regarding your question on hypotheses. Hypotheses are very important. But even more important is to know when you should propose one. Practically, that is when you can support one. Supporting means that you can provide evidence to substantiate the claim that the hypothesis is making. The more evidence (i.e., legs to support the table), the stronger the hypothesis and the more it resembles an actual recommendation.

Hi there,

This is the same issue with any other information you find on case interviews. The more you look, the more confused you get.

I noted this in a previous thread but this was part of the reason why I started case coaching and working with clients because I faced exactly the same issues when I prepped myself and saw it with my peers as well.

To answer your question:

On a high-level, the skills that are assessed are the same for candidate and interviewer-led interviews. There are more similarities than differences.

For both, you need to

create a framework
probe using hypotheses
analyze data and charts
go through some case math
brainstorm
(recommend something at the end)
all while driving the case forward (even though in an interviewer-led format, you will receive a series of questions)

The main difference is that for interviewer-led cases (usually McK), you have more time to develop your framework and also need to create a more exhaustive one (especially related to the depth of your framework → 3 insightful levels) to show more insights and thinking. The process lasts 5-8 minutes.

In a candidate-led case, you don't have that luxury but need to introduce the most crucial areas to look at, then start diving deeper into the issues you want to actually analyze. The process lasts 2-3 minutes.

Hi there,

Q1: How do I figure out which approach is the best for tackling an interviewer-led case interview when everyone's saying something different?

Get a coach with real interviewer-led experience. I've run over 200 interviews at McKinsey so I can definitely help you with that.

Q2: there's this whole thing about hypotheses. Some say you should come up with them right off the bat when you get the case, while others say to keep them to yourself. What's the deal? Can someone break it down for me? I get the concept of hypothesis, but I'm not sure how it fits into a case interview

In an interviewer-led case, you start with the case framework. From there and in every case question (math, chart reading, brainstorming), you should formulate hypotheses on potential issues and solutions relevant to the case and the information you have uncover.

Best,

Alberto

Focus first on being able to solve problems - and it doesn't matter who is leading the case.

Once you start understanding how to solve problems, start thinking about your initial approach to problems - i.e., how you would come to an answer in an efficient way (i.e., think about the result you want to get with a specific question or topic; and how that ties to getting to the case objective).
