You go in, you answer very basic interview questions, and they hire you as long as you don't have any major hiccups in your background check or something. They hire pretty much everyone who applies. I totally flubbed one of the questions they asked and they hired me. The hiring process length depends on when you apply in relation to when they're next hiring class takes place. Some people interviewed and were put into training 2 days later. I had to wait about a month until the next training class started. They also do a basic EMT skills written test that is about 20 questions.
