I applied and about 4 weeks later I got a message giving me an interview date. On the day I went to customer services and explained that I had an interview and they went and contacted the people at the mobile store and someone came over and took me to one of the rooms in the back where we did the interview. It was a 1:1 process and the questions were fine. She did skip some questions, because they apparently weren't relevant to me; I assume this is because I hadn't worked in retail before.
