They'll call or email asking you to come in for an "interview". When you go in theres 10+ other people sitting in a room with you and they sit you down at a computer for 3+ hours then tell you to come back another day for orientation which turns out to be the same thing. 3+ hours sitting at a computer. They'll give you A shirt and badge and tell you that you'll have your schedule in a couple days.
