Kroger interview questions

I applied online about two months ago and they called for an initial interview 3 weeks ago. The first initial interview was a few questions over the phone to clarify information and just a few simple things, example being "are you still interested in working for Kroger?" After that interview I was invited to come into the store to do a face-to-face interview with a manager of the store the next week. Went in early, and the interview lasted about 5 minutes overall. Literally no questions were asked, but the application was reviewed and had a small conversation. Was actually forced to ask questions instead of being asked myself. Was basically hired after being asked when I would like to start, then told that their HR manager/secretary would give me a call in order to set up a drug test time. Exactly a week later I get a call back, from the same store but from a different number, the HR manager/secretary said that my drug test had come back clean (even though I was never contacted beforehand to go take one) and that they were doing a background check and waiting for it to come back.
