Hi,

In general, there is almost no margin for error during the interviews. However, it is very hard to tell in your case as there are other factors involved with the decision, such as:

• Your competition, and their relative performance
• How much they liked you (overall, fit and case performance in specific)
• How much they need someone with your profile

Best,

Hi there!

People make mistakes and that's pretty normal.
It's more important to learn on them and try to avoid them next time. What you did is good, you said you "remade" the assumption, so as an ex-McKinsey and part of a recruiting team I would appreciate that you managed the situation and weren't lost.

But without seeing the whole performance judging on the results is still difficult.

Hope you got the offer already and my answer would help other candidates as well.

Cheers,
GB

If the rest of the cases was on point, one little math mistake won't make a dent in an overall great rating. Cases get evaluated holistically so you should be good. Having said that, it's very difficult to judge your own performance during a case, so I suggest to just wait and see.

It reminds me of a similar issue that I had myself, and I made it!
