I applied through a recruiter. The process took 2 days. I interviewed at McKinsey & Company in Sep 2009
Interview
This is McKinsey, so everything was extremely professional throughout the process. I took the initial IWIA exam and passed, and in the week before the case interview there was a lot of help in terms of practice cases and meetings with Mckinsey consultants. The case interviews themselves were completely standard - no surprises. I just got unlucky and got a hard case, so didn't get called back.
Interview questions [1]
Question 1
Tell me about a time you showed leadership of a group
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
