Early Morning Sales Associate - Interview Questions?

Hello everyone, I got a call today about an Old Navy application I filled out about two weeks ago and
set up an interview for this weekend. I work at another retail store right now that has a similar skill set, but it’s not clothing - so I still feel like I’m decently prepared.

I’m so nervous for my interview. Can someone give me a rundown of the questions I might be asked?
Also, I was searching through old posts and people in the past said they have you pick out an outfit? Is that still true? Also, what are the usual hours. I said I was available from 6am to 10pm four days a week.

Any and all answers are helpful.
