I applied through university. The process took 2 months. I interviewed at Boston Consulting Group (Washington, DC) in Feb 2013
Interview
First round interview on campus went well, was very professionally done with lots of different staff interviewing many students. 2 45-minute cases.
Second round interview in the office was a similar 2 interview format. Oddly enough, both cases were the exact same basic question "Should we invest in x?" My interview with the senior partner was very difficult and he often attempted to derail the case by asking irrelevant questions. He was very short and gave the impression that I was wasting my time. When I asked him questions at the end, he refused to answer them or would only answer "I like all my projects. I can't tell you about any specifics" which was bizarre.
It appears that the Internship interviews are mainly just a form of recruiting for full-time positions. Do not go into them expecting to actually receive an offer. Out of 4 other students who interviewed from my college, none were extended offers and all were encouraged to apply for full-time positions.
Interview questions [1]
Question 1
Cases were very open-ended with no previous information. Only, "should we buy x?"
Multiple rounds with consulting case interview portions and fit portions. Each round of interviews had multiple interviews, and the interviewer gets more senior as you progress through the interview process
