Yes, interviews are in Atlanta. Specifically, they are conducted in the offices of Air Inc (Kit Darby's company). They told us at the interview that there are essentially two ways to get an interview: 1) have an AirTran employee (I assumed they meant pilot) walk your resume in, or 2) give the resume to a pilot recruiter at a job fair (Air Inc, OBAP, WIA, etc). They mentioned that the chance of getting called for an interview by simply sending them a resume is very, very small. In my case, I did not have a cover letter for them. I met with them at a job fair and handed them only my resume.
