I know I'm a bit late for this but I work there. It was a job that I thought would be awesome and has turned out not to be so great. That said, the pay isn't bad and the people I work with are pretty awesome, I just don't get on too well with the managers. The work can be a bit annoying.
Oh and if you got the job, you would have discovered the online modules? Just do the tests and don't worry about reading all the stuff before hand. Review your answers and try the tests again. They don't actually help anyway. You learn more on the floor.
Also, what store was your interview at?
