The interview process was pretty basic. You have an orientation in the morning which is full of information and some Q & A with current pilots, then you have your interview in the afternoon and a psych test. The interview is basically a chance for them to meet you and ask questions about any "red flags" that might be on your application. They also ask questions to make sure you want to be an airline pilot, you understand the career in general and the responsibility that their program demands. Chess might give you other insight, but that is pretty much how mine went. Oh yeah, they also ask how you are going to pay for it. That is a pretty big question for them I am sure.
One thing that Rae Lynn (the Aviation Coordinator) said is that if you made it to the interview process, you are looking pretty good. They already screened people through the application. This should take some of your stress off.
Good Luck. I hope I will see you there.
