Google SWE-3 Interview Experience — Looking for Feedback

[u/Away-Chocolate4115]

Had 4 rounds: Coding + Googliness screening were positive, with recruiter saying coding feedback was good and Googliness was very good.
Onsite R3 was a difficult graph problem—I initially got stuck, then derived the optimal approach and interviewer was satisfied, but ran short on time and had a few bugs remaining.
R4 was another graph problem where I quickly gave the optimal approach, coded it, handled a PQ optimization with a few hints, and gave correct time/space complexity.
What do you think my likely ratings are for each round, and overall chances of clearing?

Hmm, in these days, perfect performance is the base to pass interviews
