Yes, I was interviewed at Google last year. This was basically what happened. Sure, they have your resume, I am not sure if they read it throughly, the interviewer didn't even know my major until I told him at the end of the interview. While, they don't stop inteview and say you made mistake, it's competitive and it's not possible to hire you. But, you know at that moment that you are not getting hired. I guess, they need plenty of reasons to hire a candidate, but just one reason to reject. I am not complaining, it seems to work for Google very well.
