Thanks Cletus for taking the time to write that up. That really makes me feel better and provides somewhat more insight into the process.

My 5 years of experience was actually divided like 3 between Masters and Bachelors and 2 after Masters here in US, so I thought my Masters grade would matter.

My interviews were 3 before lunch and 2 after. Lunch was good :).

The interview conductor asked for references multiple times, but although I knew some people working in Google, but they had never closely worked with me, so I didn't want to make up references just for the sake of it.

EDIT: "As far as releasing interview scores goes, that isn't going to happen for good reason. A score, by itself, is meaningless. Interviewers are calibrated against other interviews they've done and other interviewers. This is all in an attempt to make a fair assessment of the candidate. If a particular interviewer gives high marks to candidates where all the other interviewers don't, that gets calibrated. And vice versa."

So what you are saying is that for me to not have made it through I must have equally messed all my interviews or at least a majority of them. I surely didn't feel like that after the interview, but who knows, since I still don't have a way to know if that is the case. Then this really sucks.
