Phone Interview, then a 20 questions test, then in-person. I walked out of the interview because one guy was incredibly rude. He asked me a question I could not answer and promptly LAUGHED at me. Will never consider this place for employment.

Phone screen followed by a 2-3 hour in-person interview. Interviews were done by several different persons/teams depending on the topic. Started with the HR person who asked puzzle/riddle questions that weren't hard. I can't remember the exact questions, but they were pretty much oddly worded simple math problems. Other teams asked broad technical questions to gauge my overall knowledge. Discussed compensation and company benefits.
