Well... I did not interview at Google (yet) but I did interview for Google via telephone. I had one general interview and one technical interview. And I am currently expecting a third interview.
The phone interviews were fine. The person on the other side was very nice and very easy going. They asked some very cute questions (the kind you can find all over the net).
I don't know if I'll get a massage one day, but the interview (and the interviewers) were some of the nicest I ever had.
