The process took 5 weeks. I interviewed at McKinsey & Company in Feb 2010
Interview
I was screened by a recruiter (resume talk, personal experiences, professional experiences, why McKinsey, etc.), then had two case coaching sessions with McKinsey recruiters (went thru sample/warm up cases using the McKinsey typical questions), then had an assessment interview over the phone with an experienced consultant. Very thorough process.
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.
