IBM Consulting interview questions

Applied through university. Was notified 3 days before interview (on campus). Was supposed to be 3x30 minute interview (2 behavioral, 1 case). One of the interviewers got called away so only did case study and 1 behavioral. Was told I'd possibly get a third interview virtually and I would hear back about it within a week. Did not hear back until 3 and a half weeks later by recruiter that I didn't get an offer at all. Overall, the interview process is fairly easy. The interviewers are friendly and the case study was about implementing a global training strategy for a client. Ask questions and show your thinking. Behavioral is made up of "tell me about a time when you did x..." and some personal questions too. My only complaint is that IBM takes forever to get back to you. A whole month to find out I wasn't getting a third interview or an offer. Also, it seems pretty biased that they prefer candidates who have studied abroad, as it makes you seem more well-rounded.
