Applied through university recruiting website and was offered an interview at my school. Two 30 minute interviews, one behavioral and one case, and the interviews are back to back. Interviewers were young and friendly, but the case interview was formatted very differently than any others I had prepared for. My interviewer didn't want me to take any time to think about the problem or do any calculations, but instead he would ask hypotheticals and want to see my creative approach to answering them. For the internship, there is only one round of interviews before they extend offers.

The first stage was sending in a cover letter and resume. The second stage was three consecutive interviews, with the duration of 30 minutes. There were 2 case interviews (consulting style) and one fit-interview. Finally, there was a logical timed math test with multiple choice questions (you ere allowed to have a calculator).
