Some minimal email contact with the recruiter, then the first interview is set up w/ someone from HR. She/he basically just tells you about the position, sees if you are still interested. That one is relatively low key. The next interview is 2 hours long. You spend an hour at a location, observing the day to day activities of the branch. After that you interview with the Area Manager. A little more intense than the first, but still pretty straight forward. They want to know that you aren't going to buckle under pressure and that you like people. After that the third interview is with a manager and a regional manager. Significantly more intense. They want to know that you can stand the hours, the pay, the tough situations. Being friendly and talkative is a huge plus. As long as you can keep your cool and are quick with your answers, you are golden.
