There were 2 rounds of interviews & a case study. First round with an HR recruiter, then second round with two managers, both of them were relatively easy and in a very friendly environment. Then for the case study you had 1 hour to prepare the case alone, not in the way McKinsey or BCG work where you work together with the interviewer for the solution. In BearingPoint you had to solve it alone and then present it to the managers. Not so easy, but also not extremely hard to find solutions, but it was expected of you to have knowledge and be ready for anything (something that is not so easy to do if you are looking for an internship, apparently you don't have consulting experience and cannot be ready to give all the right answers).
