Hi there,

Q: Is it true that there are no right or wrong answers in case interviews, specifically when it comes to McKinsey, or is it just a myth?

There are for sure wrong answers in a case interview – a simple example is if you do the math wrong or you get the wrong insight from a graph.

Hi there,

This is a myth.

There are certainly right or wrong answers but what you probably mixed it up with is that there is not one single correct solution/approach, for instance, when creating a framework.

You can approach a case/dissect a problem in 10+ different ways and would still get the same analytical outcome. This is what is tested in McKinsey interviews.

There are also 100s of ways to get it wrong though, mainly if your framework is not broad enough/too broad, not deep enough and/or not insightful.

If you want to read more about that, I published two articles on McKinsey interviews here:

• McKinsey Case Interview
• Personal Experience Interview

That's rather philosophical. 

Maths has a right or wrong because it's maths. 

Structuring, brainstorming, chart interpretation, recommendations are less about right and wrong because they are more concept and content- (rather than numbers-) driven. 

Still, there are BETTER structures and WORSE structures. So lots of structures are good, but very few are distinctive. 

If you're looking into this, you might find this article helpful:

And also this workshop I run on first principles structuring:

Hi there,

It is a myth. There are plenty of wrong answers. 

What it is true is that there is plenty of potential solutions to the case and what is valued during a McKinsey interview is the thought process you follow, your business sense and your consulting skills.

Hi there,

as the expression goes: Many roads lead to Rome. 

As long as you arrive in Rome, you are usually fine. But there are plenty of possibilities to get tripped up along the way. 

Turning this back to your question about case interviews - there may not be only a single correct approach to arrive at the correct solution. But there can be many wrong ways to go about a problem which then will never result in the correct solution.

So whatever you heard in this regard is a myth.

Hi there,

I would be happy to share my thoughts on your question:

• First of all, it's true that there can't always be just one right answer.
• However, there are certainly many wrong answers or approaches, be it in the initial structure, brainstorming initiatives, etc.
• Lastly, this is completely independent of the consulting firm, as the business reality underlying the case studies does not change depending on the consulting firm.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

That is true. It is not the answer that matters, but your answers have to be supported by sound logic and evidence.
