It was simple The hiring manager asked me about my availability, why I left my last job and if I had any cashier experience. After answering those questions she asked me when I could start. That was it took no longer than 10 minutes from start to finish.

Super easy, they basically just ask you about any experience and then your availability. It is very informal, jeans and a sweater work for an interview outfit. Overall, the interview probably lasted about 15-30 minutes.
