Interviewed at UPS last year. 30 minute sim ride (mine 707) which was pretty much a takeoff into the pattern for an ILS. Sim went great, then to the interview. The HR gal was great, friendly etc, the managment pilot was all over my #$$ about every little thing I said. I left knowing that I had wasted my $$ flying in for the interview. Lo and behold....to my great surprise, about 2 weeks later got a call asking me to return for the medical and then to start in the next class.
I'm not sure if they were doing the good cop/bad cop routine, but it sure left a poor impression with me. In the end, I turned down the job offer. That being said, I have some great friends who work there and really enjoy it, and everyone I spoke with raved about living in Louisville.
So, the moral of the story, learn about the company and keep your cool if things start getting a bit crazy. Worked for me.
Best of luck to you.
