Starts off with some behavioral questions. Main focus of the phone interview was on technical side. All the technical questions were related to probability.

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.
