I was brought in for a f2f interview which was going to be held at a nearby hotel. They flew me in the night before and I wanted to be very prepared so I stayed in the same hotel the interviews were going to be the next morning. That evening there was a man down in the lobby who was drunk and very hostile, he spoke to me and made me very uncomfortable. The next day it turns out he was one of the recruiters! I wasn't offered the job but even if I was I wouldn't have accepted. It was very inappropriate and I should probably find a way to report it further, but it sounds like from talking to the hotel staff that night he has been with the company for a long time and is well known by the staff at the hotel at least.
