During my round 2 case interview with an associate partner at McKinsey, I was asked to calculate breakeven quantity for a go/no-go kind of business case. I explained all the steps before calculating, wrote things down and shared what I found at the end with some additional information. Then, a strange thing happened: the interviewer took the paper that I did all my calculations on and checked my answer and went through her papers in silence for around a minute and a half. Once she finished checking, she gave it back and carried on the interview as usual. The answer that I found seemed reasonable and made sense. I was wondering if this is common in round 2 interviews and what it really means. I will appreciate any kind of help/advice to prepare for my next interview to avoid such a situation as it affected the pace and the rhythm of the interview.

Hi Anonymous,

to me it sounds like you came up with the correct result, but chose a calculation approach that was a bit different from what the interviewer had prepared. So it seems that (s)he just wanted to make sure that your approach/calculus was robust, in order to exlude that you reached the correct answer by coincidence (this sometimes happens). I wouldn't worry about this - the way you describe the situation all should be fine.

Cheers, Sidi

Agree with Sidi. I'd usually expect the interviewer to ask questions about the methodology (sometimes on the fly - this is what I do in case prep for example) rather than take 90 seconds to review everything visually. The fact she didn't point out a mistake also makes me think all is good. If so, and assuming your path wasn't significantly more complex, I'd even give you extra points for being creative in how you approached the problem.

Hope you hear back soon, let us know the outcome.

Hi A,

My first thought after reading your message was similar to Sidi's. It seems you did calculations correctly but in a different way than the interviewer expected. Besides, you did not get any negative feedback that you made mistakes.

Anyway, do not overthink it and better get prepared for the next interview.
