I applied through an employee referral. The process took 2 weeks. I interviewed at Bain & Company (London, England) in Sep 2011
Interview
After a referral, I was invited for 2-stage interview in the first round. 1st stage was a simple market sizing as well as discussing CV. 2nd stage was a case study that was simplistic enough but still required thought and structure.
For the final round, there are 3 stages. First stage was a case study but a lot tougher (should have been more structured) as well as the second stage. I had the exception of having a market sizing in my second stage. Final stage is a written-case study where you are given a lot of materials (slides, graphs, clippings) with 35 minutes to review and fill in a set of blank slides that are provided. You are then to talk it through a consultant who will listen to what you have to say.
I failed to be "more" structured and not creative enough and as a result, not offered a position. Amazing experience and it was my first - which was a shame because I know with more practise, it gets easier.
2 cases for R1. Pretty straightforward cases about revenue optimization opportunities. There was a little bit of market sizing but all data needed was given. No behaviorals asked in round 1 for me.
