First interview was phone interview. Basic questions at first then there was some analytical questions that tested how you think on your feet. Some of the questions were based on the airline industry.
Second interview is in Dallas they fly you out first class and of course they put you in a decent hotel. You are assigned a company host who calls you when you land to answer any questions, and the host also takes you to HQ in the morning. There was four back to back interviews were you are asked a mix of behavioral and analytical questions. Some of these questions are a little challenging and some are not bad. My best advice is to learn about the airline industry. Know what problems are facing the industry and how airlines make money. Remember differentiation!!! Know ways AA can surpass its competitors. Basically, do your homework and you should be fine.
After two weeks I got the dear john letter. I was not surprised because I had not prepared well enough for the analytical questions. As a plus the hosts that you meet a quite friendly and they really make you want to work for the company. The make the experience laid back and enjoyable.
