After interviewing at multiple FAANGs, I would advise against generalising company culture based on single interview incidents. Sure, it is not nice but well...it happens. They are interviewing hundreds of people, employing thousands of engineers, and these engineers are also training themselves in the context of interview skills. Assuming the Google interviewer was honest in his feedback (i.e. noted down wrong indentation as a minus), I would bet this is caught somewhere in the hiring review process, eventually pointed out and corrected on Google side. The downside is, sadly, that you get rejected, but ultimately these companies can afford rejecting good candidates.
