Subway Crew Member interview questions

The interview was fairly quick, compared to previous experiences. I applied on a Sunday night, i got a text on Wednesday to come in for a interview on Thursday. The interview was really quick, but she had me waiting 10 min before we started the interview. Then as the store got a little busy, she interrupted the interview where i was waiting 5 minuets. Then she said she would get back to me via text. I called on the following Monday and was notified i got the job through text. She texted me formulas to memorize and told me I would be starting Wednesday, basic 4 training hours.
