I would say just be prepared to work in a fast-paced environment, and working over the phone. They do have full-time and part-time shifts, so it just all depends on how long you feel like you can sit there and talk to people. They teach you a lot, so you don't really have to go in knowing everything about credit cards. That's pretty much it. It's a professional environment, but you don't have to dress up every day. You can come in wearing what you want to wear.
