Main focus of the phone interview was on technical side.
All the technical questions were related to probability.
I applied through university. The process took 4 weeks. I interviewed at Kroll (Palo Alto, CA) in Oct 2014
Interview
first round interview on campus, 45 min. Most behavioral questions (tell me about a situation ...) The technical question is about probability, expected value etc.
After a week, went to Palo Alto office for a super day. 4 back-to-back 45 min interviews, one of them is a technical interview, the question is about basic probability. Others are behavioral similar to the first round.
