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.
3 step process. first was a screening then followed with around 7 case studies. the case studies ranged in varying industries and scope. this was done over a course of 2 months
Too long, too many rounds, too many people interviewing you and you need to follow up several times in order to get a response. They give you the materials to prepare which is good, but everything else is suboptimal
Das erste Interview war mit der HR. Klassische Fragen - Führ mich durch deinen Lebenslauf, warum Consulting, was motiviert dich etc. Das zweite Interview ging 3 Stunden. Nach einem kurzen Kennenlerenen, kamen zwei Case-Studys dran - eins auf Deutsch und eins auf Englisch.
