The process took 1 day. I interviewed at McKinsey & Company in Oct 2010
Interview
PEI: Personal Experience Interview, where you need to be as specific as possible about a leadership situation and how you contibuted. This was followed by a case on the wine industry and followed by 5-6 minutes of my questions.
Then off to the second interviewer, beginning with 'tell me about a challenging situation where you were up against senior leaders/groups". Then a case about a school system in springfield, and a few minutes for questions.
After these two interviews was the 60 minute PST. Harder than the GMAT, so prepare appropriately.
I interviewed at McKinsey & Company (Ciudad de Mexico)
Interview
Interview process was really great, all interviewers were friendly and professional. Started with a phone screen, then two case interview rounds with a partner and a senior associate, followed by a final round covering fit and problem-solving skills
Interview questions [1]
Question 1
Tell me about a time you had to influence someone without formal authority
It was a one-to-one interview with a consultant. It's a typical case study. The experience was traumatizing. I know my answers weren't great, the consultant was elegant and didn't bother to hide his boredom.
