I applied through an employee referral. The process took 2+ months. I interviewed at Google (Mountain View, CA) in Jan 2011
Interview
I was referred through my neighbor. I had a phone screen, and was passed on to an in-person interview, which consisted of market-sizing and brain teaser questions. I believe I started the process in November. I had the phone interview in December.
I was scheduled for an in-person interview in January. I met with 5 employees. I was given one particularly tough consulting-type question. I didn't get any feedback on it, except that if I thought of a better answer, I should email this employee my new answer. Of course I did this, but I didn't get confirmation that it was received.
Later that week, I heard that I did not get the job. The recruiter offered to recommend me to other positions at Google, which she did, but those never got past the phone interview stage.
