I applied in-person. The process took 5 days. I interviewed at Coach (Chicago, IL) in Feb 2011
Interview
Really pretty simple. Know some information on the company and stress that you know how to work well with customers. The interview process was a very basic "tell me about yourself" type thing. They are very willing to train you and help you improve constantly.
I went in to turn in an application and the manager asked me a couple questions on the spot. She asked me two questions right at the counter in the store. It lasted under ten minutes and she told me that they would be in touch.
