The whole selection procedure, right from applying on my college website to the decision took about 4 weeks. The first round of the interview comprised of 2 sections- 30 minute behavioral interview- It was relaxed and was more like a conversation, started from tell me about yourself to which service line are you interested in. 30 minute case interview- The time was less for a case interview, in was a specific case where a new ERP system had to be developed for a company. The results of the first round were declared the same evening and the second round was on the next day. The final round of interview was a 45 minute case interview. It was a global implementation of ERP systems of M&A. Was very detailed and ended on a few behavioral questions and which service line. I would suggest- Be confident, be yourself, be thorough with your resume and you are all set!
