I was initially contacted by a recruiter who found my resume from my college's career management center. The process was very quick, I was flown to Seattle with all expenses covered. All of the interview logistics were very streamlined and I was impressed with everything in that regard. As for the interview process itself, it was quite stressful. The process consisted of 4 back to back technical interviews. Every question I was asked involved coding the solution on a whiteboard. The questions focused exclusively on data structures and algorithms. I wasn't asked any trivia type questions like "What is OOP?" or "Explain garbage collection in Java". My advice would be to make sure you are keen on algorithm questions, and to prepare at least a month in advance.
