I had a single one-on-one interview with the district manager who would hire me, after an initial phone screen. It involved the usual sort of questions (tell me about a time you had to deliver in-the-moment coaching, tell me about your recruiting process, tell me about a time you had to address a customer complaint about the service the customer had received, etc), plus a bit of role-play on the sales floor. It was a fairly quick process, and I got an offer a couple of days after the interview.

It was done by a panel of leaders and the district leader. The interview was done at a hotel and based on how well you did you would go to the next person and until you got to the end.
