You have to apply online, then wait for a response on your email and wait until they call you to schedule an appointment for the interview. My interview was in the morning about 10 am and lasted about 2 hours. if they like you, they tell you right away and they start checking your background immediately with a third party. Once you pass the background check they call you again to start your 2 day training and that's it you're in.

I had gotten called for a group interview, and during which I felt like they were TOO focused on getting through the 5 other people rather than listening to each.
