I spent 3 hours doing onsite interviews and then never heard back from them. I was working with an outside recruiter who couldn't get any feedback either. After a month, a friend of mine who works at Google, contacted HR to find out the status of my interviews. Only 1 out of the 4 people I had interviewed with had submitted feedback on my interview. The internal requirements are for all reviews to be submitted with 24hrs, which are then used to assign a score to you. The internal recruiter never followed with the interviewers and after getting a call from his boss (my friend has pull and escalated the situation) the internal recruiter finally called me back and said they were going to pass. I asked him how they could make that decision without having any feedback on my interview. He just said they had lots of candidates. Basically, I fell through the cracks and got screwed. In hindsight, I am very glad I took my current job and am not working at Google.
