The interview process was fine compared to the horror stories I've heard. I had 1 long interview with the manager, then 6 short (30 min) interviews back-to-back with the team over the course of an afternoon. A couple of technical questions but nothing rediculous. They hired me based on credentials, so the tests were ceremonial if anything. It was more about discovering whether I would get on socially with the team.
You normally get an offer after 3.
EDIT: I'm downvoted, but this was my experience at Google/Facebook. There were exactly three steps. There can be more if they ask a follow up if you're borderline in some of the interviews but it's not the default.
Were your post-onsite technical?
At the end of the day it’s a couple hundred hours of effort in exchange for years worth of upside. I think when you compare it to the amount of preparation athletes, performers, or service members go through, it really doesn’t seem so bad.
FAANG might be interesting but their interview processes kill it for me. I have no idea how people find the time to do homework for it + are willing to spend months in this lengthy interview pipeline.
(Also there are problems with FAANG type companies being generally kind of evil these days, of course)
