Check the Air Wis QOL thread on this board....has PLENTY of info on AWAC. I interviewed two weeks ago and got it.
First 45 min are an overview of the company, etc...Training guy answers questions(HR will give you a heads up and remind you to make a good impression with this guy when he comes in because everything you do there is a part of the interview process).
Tech questions were on an approach plate into AVL...DH, the mins, missed approach, what type of hold. Basic IFR stuff you should know.
Typical HR on why you want to be here, tell me about a time when, etc. Wear a good suit, smile, shake hands and make a good impression. Straight forward interview...normally 4-5 people in a 4 hr period(45 min each). We then were taken for prints, pee test and given offers.
