Overall, I have an extremely amazing experience with this interview. This is my first one with FANG so I was nervous. I felt quite sad that I should have prepared behavioral and system design a lot better. The technical questions were not hard, but missed on some edge cases.

The recruiter haven't yet replied to my followup email. How long should I expect to wait for the result? What are my chances of getting an offer. I saw most of the people got an offer right after the interview, so I assumed I got rejected. I felt dead inside atm.
