I applied online in January and received an e-mail in June to call and schedule an interview. My interview was held in Houston and they flew me out for it. I arrived early and was seated in a room with around 100 applicants. They started by showing a short video about the company and then one of the recruiters briefly discussed the job description and answered a few questions. Then the recruiters (all of them were flight attendants) called names one by one for interviews. I had a one-on-one interview with a recruiter where he had me read an announcement and then asked me a few questions. He asked if I had questions and then he told me to take the shuttle back to the airport to get something to eat and return in an hour for a second interview. He asked me not to tell people on the shuttle that I was asked back because some of them weren't. When I returned for round 2, there were about 40 people left. Recruiters again called us in for one-on-one interviews and this time each person had a different recruiter than before. I was asked a few more questions and then taken to a "secret room" (they actually called it that) where there were only 8 of us left. A higher up (I assume) came in and called people out one by one about every 15 minutes. I was taken into a board room and seated at the head of the table with a man and woman who I assume were the head recruiters. They asked about my previous job experience and then invited me to training. Then I was taken to a small office to fill out some paperwork. Everybody was extremely friendly and my advice would be to dress professional. This means a jacket and close-toed shoes. Out of the 40 who made it to round 2, only 2 applicants weren't wearing a jacket. Also keep a smile on your face at all times. Good to ask questions when they give you the chance as it shows interest.
