Subway Cashier, Sandwich Maker interview questions

When I arrived the store was empty and the manager came out and I told her I was there for an interview. I shook her hand and we had a seat and we had a one-on-one interview. The interview wasn't long at all, probably a 10-15 minute process.

Walked in asked for an application filled it out and returned within 10 minutes. Asked me simple question like when are your availabilities? Are you in school? What days are you available to work? And i was hired the next day started training 2 days after interview.
