Oh here's another one - I was interviewing at Google and got an offer, and I decided to ask for a meeting with the HM because the other job I was considering at the time gave me an interview with the HM that was really enlightening and made me feel good about taking the other job over Google. I figured it would be a good way to directly compare the two jobs since the comp, etc. were similar.

The moment I met the HM I wanted to leave. He was brusque, felt like our entire meeting was a waste of time, and was, quote, surprised that they had finally filled his job req. I tried to brush this off as him having a bad day, and sat down for coffee with him. We started having a stilted conversation in which I mentioned that I had just adopted a dog, and his first response was, "oh god, I _hate_ dogs, please never bring it to work."

That was kind of the end of that. Sure, maybe it's petty, but I was getting bucketfuls of bad vibes from this guy.
