Walmart Intern interview questions

The interview seemed very relaxed. Asked questions about my past work experience. After first interview they gave a second interview with a different manager. The second interview was almost identical to the first on with the questions slightly different. After that interview they sent me home and told me to call my references. A couple days later they called me to schedule a third interview which was mainly paperwork, signed for my background check, and they told me where to go for my drug test. The manager told me it would take 5-7 days. The drug test must be done in 24 hours or you can not have the position. I took my drug test on Monday and was called Saturday.
