The process took 1 day. I interviewed at McKinsey & Company (Atlanta, GA) in Oct 2009
Interview
First round interview consists of the McKinsey Problem Solving Test. This consists of 26 multiple choice questions on 2-3 business cases presented within the test. Expect to need to perform math by hand that you haven't had to do without a calculator in years, and to do it as fast as if you had a calculator.
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.
