Well, I arrived nice and early like they always suggest you should do as someone hoping to make a good impression. I waited longer past the appointment time than the time that was spent in the interview (For example, the appt was at 11am, I got in at 11:10, and I was out at 11:15). Someone was in there talking aggressively and came out looking red faced and stressed. (This should have been a red flag of things to come)
