The process is very relaxed and laid back. Interviews are conducted in both CLT and PHX, and the process is the same. The schedule generally permits you to fly in, interview, and fly out on the same day. There is no written or computer testing or simulator evaluation. The interview is two three-on-one panel interviews in TMAAT format. One leans more toward the technical and the other more toward HR-type questions. You will be made to feel as at ease as you possibly can under the circumstances.
Response times vary widely. Some have heard in as little as a few days, but lately it has run out to as much as six weeks, whether the answer is yes or no. The NO comes in the form of an e-mail, and the YES comes in a phone call from the VP of Flight Ops, generally.
