Sam's Club interview questions

I applied online months ago, and I received a call last week to schedule an interview. I wasn't told what I was interviewing for, but I needed a job so I went anyway. There are a total of three interviews. The first two were held in the cafe area, which I thought was kind of unprofessional and distracting. Each interview was composed of a few three part "STAR" questions. In each interview, the interviewer asked the same type of questions but reworded. If they like you, you're in the door. After they called my references, I was scheduled to meet with the manager for a third interview. During the third interview, she basically asked me about myself and offered me the position. I had to sign some paperwork for a background check and then take a drug test. Still waiting on that background check...

Was called in for an interview, proceeded with the interview and was told i was going to have 1 more manager interview me, called me back a few days later asking for one more interview was told i was going to be hired and need to drive to a nearby location to submit a drug test within the next 24 hours.
