I went into the store to apply and was directed to their website for the process. The online application is pretty typical- they ask a lot of questions about what you would or wouldn't do in certain situations at work. They also have a few picture questions where you say what you think is wrong with the photo of the mannequins and the clothes that are folded around them.
I was given a 1 on 1 interview at the store and it went well. There were standard behavioral questions, a few about my personal experience, and then a short role playing stint where I had to convince the 'shopper' to get an Old Navy Card.
