You go in to the office and unless you're a criminal or can't hold a conversation, you're hired. Even though you get offered a job on the spot you still have to do a week long in-house security license, which you have to pay for.

It was brief but professional and well put together and straight to the point. They offered me a job on the spot and later sent me an email with their offer. I signed Electronically and the training process stated shortly after I accepted.
