I applied through a recruiter. The process took 3 months. I interviewed at Google in Dec 2011
Interview
There was an initial phone screen to cover fit and possible openings. This was cultural and focused on achievements as well as communication skills. Then there was a long gap to schedule an in person technical round. This consisted of a few engineers and was very technical. There was no strong communication of expectations of the role and the title and many groups spoke. Another round of interviews happened two months later and it was the same process with vague communication of possible roles.
