Bain usually has case interviews typical of Consulting firms. This winter they implemented a new technique of giving applicants 1 hour to look at a stack of slides and then make some recommendations during a presentation. This stack of slides varies for each interviewer in only the way it is printed. For some it is printed on both sides of the paper, for some it's stapled together, for some it's only paper clipped. I was put in a room with 30 other interviewees to go through the slides, so there was very little room to spread out. The advice I've heard is that on the "recommendations" slide you have to fill out, keep it simple. One or two is all they are looking for.
