Walmart Overnight Stocker interview questions

I went in for a interview at 10:30pm I spoke with a assistant manager and the co manger they basically hire me right there sign background papers, they don't drug test no more but they still asked a few questions about why I want to work for Walmart, and Do I see myself making a career out of Walmart

I underwent a total of 5 interviews consisting of 2 with "Zone Managers", 1 with an Assistant Manager, 1 with a Co-Manager, and the last with the Store Manager... i was asked various questions about random scenarios and was told i would be contacted within a week and told if I would be hired... i was called the same day and told I would not be working as an overnight stocker like I'd asked for but for a Photo Lab Technician instead.
