I worked at one the FAANG and I found in my team and some of the neighboring teams the most insecure, unfriendly, back-stabbing, conspiratorial bunch of technically semi-competent losers I ever had the displeasure of working with. Other people were competent, trustworthy, confident in themselves and thus enjoyable.
I also interviewed at other FAANGs and maybe the interviewers were all wonderful people, but I had a mixed experience. Some appeared to be ok, some definitely not. Very different experience from the parent's.
I think a lot of people would enjoy a blog post elaborating on that experience (possibly under a pseudonym to protect you from vengeance).
Wonder what the false negative rate is?
Google's culture and hiring process is so well documented at this point, I suspect any suitably talented individual could appropriate some cultural fit.
Of the (current and former) googlers I know personally, they are a mixed bag but there are some traits that are more common. Self assurance and the uncanny ability to never be seen to be demonstrably incorrect are prevalent tbh - but that applies equally to most of the industry.
I think that may be very easy to do, just state that everything you say is just a theory or your opinion... but this is just a theory.
