I was invited for one more interview after the two first at McKinsey. Why and when it happens? Does it happen at the final round too?
Third interview at McKinsey
that usually happens after the first round when interviewers are uncertain about your overall performance. It is likely that one of them found ok to move you to the final, while the other had doubts; they thus moved you to a further interview in order to make a final decision. In case you manage to do well in the next interview, you will move to the final, as if the first round was succesful in the first place.
This is very country (not as much office) dependent. However, the typical format is that you have 4 final round interviews with Associate Principals, Partners and/or Senior Partners (formerly Directors). The 4 final round interviews are conducted on the same day 95% of the time. If there is a real shortage of APs and Partners, they may only conduct 3 interviews. If they can’t even schedule 3 interviews with APs and Partners, they may ask you to come back for another interview. This is not usually a sign that they need “another read”. This is also usually only the case if you are locally based. If you are traveling for the interview and they have a shortage of APs and Partners, they likely ask you to reschedule.
All of the APs and Partners don't need to say YES for you to get an offer. It helps but if there is a NO or even two NOs, you need to have a really strong YES advocate (the more senior the better) in the decision meeting. The decision meeting is not a vote. Basically, all of your scores have been put into a database from all rounds and are displayed on a screen for all of the final round interviewers to see. The leader of the decision meeting asks for someone to "make the case for" and then someone to "make the case against". Everyone listens to both sides and then there is a discussion before ultimately a consensus is ageed upon.
I don't know for which office and role you are applying for. A Mckinsey recruiter for consultant position told me that all process consists of 4 interviews:
-2 with 2 consultants
-2 with 2 partners
All need to say yes and you get an offer
