received a Phone screening invitation shortly after applying online. Asked both behavioral and technical questions and no response afterwards. Seems to be a very nice guy who would give you hint if you get stuck.

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.
