The interview process was a lot for a simple position. I think one interview is enough for this kind of position. I think two interviews waste people’s time. I also had to wait a while in line before I could talk to the manager

Sit down interview with the store manager and the district manager. Very normal interview questions. Dress professionally. Act like you care about the job and company. To really secure it mention that you're open to working in leadership/mgmt position in future.
