The Home Depot interview questions

Applied online, was called within a few days of applying for a phone interview. I was asked a few very generic interview questions and then was scheduled a in-person interview at my local store. My interviewer was very welcoming and asked questions about my past experiences relating to the job and how I would/have acted in certain situations in the past. I was offered the job on the spot and accepted, pending a background/urine test. It took like 2-3 weeks for them to call to set up a orientation... I had called a couple of times wondering why it had been taking so long and they had told me they were waiting for the urine test.. I guess the wait is common in the company though.. Many others I work with had the same long wait.
