You sit down in a room with the interviewer and they ask you a lot of standard questions. They're very friendly and pretty relaxed, so there's nothing to worry about. If they accept you, they call back either later on (or the next day) and schedule a drug test. They let you know that it's a Saliva test (stay hydrated) and they're really quick to take. Once they send that off and get the results, they let you know if you're accepted and when your orientation will be.
