After submitting my resume I was given a month to study the city codes for all the airports in the U.S. On the day of the interview I fist had to pass city code test and then the people that passed were divided into small groups for the interview process. They asked basic questions although it was somewhat stressfull that there was a panel of people interviewing us and not just one. They sent a few of us home and told them to wait for a phone call but they kept me and a couple others behind to let us know we had gotten the job.
