So goog recruiter got back to me today and said results from onsite are mixed but there were definitely positive results so they will present to hiring committee... Do I have a good shot of going through?
No
still a chance, but only if the bad interviews were borderline and you covered the weak aspects in other interviews
Recruiter did not ask me about this today.... Should I bring it up?
How it went, OP?
You got one shot but not a good shot. Google expects you to score all A in all rounds. You may pass if you are lucky enough, but ask for additional screen if you get rejected.
you certainly don't need to get "A"s in all rounds. don't even know what you mean by "A" anyway
This is not true if by “score A in all rounds” you mean “get strong positive feedback in all interviews”. If you flub an interview it won’t sink you, especially if other feedback is strong
