First, you go in just to fill out an application. BUT they don't tell you that's what you're going for, or if they do, they don't mention that you should dress for an interview. Sneaky way to see how much you want the job & how professional you are. They gauge you on how long you take to fill out the application, whether it is completed, spelling & grammar, etc. If you make the cut they invite you for a group interview where, among other things. Then, if they invite you for a working interview you are pretty much in unless you screw up big time.
