I submitted my resume through campus recruiting and got a call a few weeks later asking to set up a phone interview. The phone interview lasted about 30 minutes, included mostly behavioral questions and "walk me through your resume" and "what are you most proud of". The phone interview was followed by an email with a "test" with probability type questions and it had to be sent back within 30 minutes. About a week later I got another call offering a second round interview at headquarters in Fort Worth. They scheduled me to fly out early in the morning and land at DFW by 8am where I was met by a host for the day who picked me up and brought me to the office. After getting visitors' badges, several other candidates and I had a brief meeting with a manager about the RM department, then we each had 3 back-to-back 45 minute interviews with different people. After all of the candidates finished their interviews, AA hosted a lunch for us at a Mexican restaurant with all of the hosts and a few managers. I was on a flight back home by 3pm. Other candidates from out of state were put up in hotels for the night before and also flew home after the lunch.
