You sit in a small conference room with two of the collections managers where they ask you a series of questions. The target word for the interview is money motivated. As long as they know you're there for the money and are outgoing then you are good.

Very transparent and easy. First you're invited to take a test if you apply and qualify and then if passes, interview and offer. It's a very organized process and the hiring managers with the team leads interviews you, usually a panel of 2 or more. The hiring managers decide weather they want you or not. You just have to show you're tough enough to collect!
