The process took 2 weeks. I interviewed at McKinsey & Company in Jan 2010
Interview
3 interviews in first round, 2 interviews with partners in second round. All interviews included a case. The first three interviews aimed to assess based on the four parameters: Leadership, Drive, Personal Impact, and Problem Solving. All three first interviews started with a short presentation of CV. Then the interviewer tried to assess one of the parameters: Leadership, Drive or Personal Impact. First Interview: Describe a challenge you have had. Second Interview: Describe leadership situations. Third Interview: describe your drive. The case aimes to assess problem solving.
All cases included a great deal of business sense and numerical calculations. All cases started with the question: describe your aproach to solve this problem.
Interview questions [1]
Question 1
Describe a challenge you have approached and how you approached it.
First, there is a computer test screening. Then, you get invited for the first round interview, usually conducted by an AP. Then, for second round, you have two interviews with Partners. You get feedback quickly, less than a week between interview and feedback
3 stage interview with increasing seniority. Opportunity to prepare with current colleagues prior to interview which was useful. Straight forwards process, no big suprises if you prepare in advance but prep is needed
Prepared for assessment but did not make it through first stage. Not difficult but high pressured with time constraint. Lots of materials on youtube which can be used for reference
