Went through a phone interview, and was then flown out to Redmond to interview. Campus was beautiful and so was the hotel they paid for me. Everything except the interviews themselves were amazing really, but once actually getting to an interview it was extremely difficult to understand what my interviewers wanted me to do as well as to physically understand their thick accents. Technically the questions were a split between standard algorithms questions, and more difficult algorithms questions. There were a few non technical questions, which I didn't understand (something about twitter and sentiment analysis but what the interview actually wanted for a solution was difficult to understand)
