Lowe's Home Improvement Customer Service Associate interview questions

I interviewed with 3 different managers basically the same questions. After the first approved of me the other 2 didn't seem to care about the interview just seemed to go through the process. I got a call the next day asking me to start the following week.

Walk in.. notify associates of your arrival. That person in turn then goes back to notify the human resources manager. She/he then conducts the interview consisting of 15 3-part questions regarding your previous work experience. Some are relevant, most aren't. It's all a very annoying process in my opinion. After the first interview, you're taken to another office for a second interview and then a drug test. Cotton-swab drug-test.
