Walmart Overnight Stocker interview questions

Took 2 weeks. They called for an interview after I had applied online. Then I took the interview that next day. The questions were difficult, in my opinion. They asked questions that would be something I feel would be more for a manager. Thankfully though the lady interviewing me "felt bad", because even she was like, "why are these even questions", and so I was called back for a second interview and this time, I did my research.... (I didn't think I'd need to, because it was Walmart and I figured the questions would be pretty basic.. Wrong), anyways.. the next interview I felt sooo much better and felt I "aced it", "Tell me what you would do if you had to address an angry customer." etc.

Brought me in. Asked me one single question. "Can you give me a time where you showed great customer service?" Gave my answer and then proceeded to hire me on the spot for a job.
