i had a phone call with an HR person to start. That followed with a phone call with two engineers who gave me basic programming questions and experience probing. Then I was flown into their headquarters for a full day of interviews. The day started at 8a with an hour long tour of the facilities (which is quite the experience), then starting at 9a i had a series of interviews with two people rotating in every hour. At noon I went to lunch with several people (which iI found out afterward was actually part of the interview) and the interviews continued in the afternoon. These interviews were very technical in nature including logic problems, whiteboard coding and even coding a solution in Java on a computer. The day ended with standard HR interviews to make sure I wasn't a serial killer or whatever.
