Google Software Engineer interview questions

I applied for the position through the Google jobs website, and I was contacted by a recruiter in a few days. Initially the recruiter asked me about things such as if I had previous interviews at Google, and if I have an internal reference, and where I am in the job search process. There were two phone interviews, typical algorithmic questions. In my onsite interview day, I had four/five other interviews, which were very similar to the phone interviews, except that you use a white board.
