Recruiting process at McKinsey is long and hard. I had to take the a test called Problem Solving Test (PST) where over 90% of applicants failed. And on top of it is 5 rounds of interview with 5 senior consultants (Engagement Managers, Partners, Directors..). In interviews, behavioral questions are very lightly touched. Most attention was on the case interviews. My 5 different interviewers have 5 different cases but a quite similar style. All of them gave me the "Interview-drive" type of case. I guess you can read more on this type of case interview at www.mconsultingprep.com/case-interview 5 interviewers each independently evaluate my performance on a scale which looks something like: Strong hire, Consider, No hire. If you get any "No hire" from any one of the five, you are out. If you get more than 50% "Consider", you are also out. The nice thing about this all is that once you get in, you will all be hanging around with smart people :).
