A Google recruiter contacted me early in the summer (I had interviewed with them previously) and set up a phone interview. I passed that, and they sent me an invitation for an on-site interview.

The visit to their Mountain View HQ was very pleasant. I had:

• Two interviews
• Lunch with a Google employee
• Another two interviews

I did not find the interview problems particularly difficult and solved most of them well before time ran out, so I ended up with a lot of time to chat with the interviewers. I think I got them all correct (I hope!), because the interviewers didn't really have many comments about my solutions, and they didn't tell me that anything was wrong.

They told me it would take around two weeks to give me my decision, but it ended up taking ten weeks. This was because one of the interviewers left the company without turning in their interview feedback, so I had to do another phone interview. I think some other stuff got lost, so the recruiter contacted me and asked me to fill out some more forms. Either way, it took a really long time, and I was disappointed when I did not get an offer :(

I signed an NDA, so I cannot say. However, there are some brainteasers before the main coding question in some of the interviews.
