When you go in to interview, you'll go to the recruitment center. There are typically a lot of people there, so don't think you'll just be in and out. The longest part of the interview is the wait to actually meet with someone. Once they call your name, you'll go to a booth and they'll ask you for your social security and ID. They'll ask you about your preferred schedule, any accomodations you may need, and walk you through the process of being accepted and beginning training. Then, you'll do your drug test in a separate room using a cheek swab. Once the results of your drug and background tests come back clean, they'll email you and you get started with the hiring process.
