Walmart Cap II Associate interview questions

I went into the store and up to customer service. They directed me to the back of the store where I waited a bit for a manager to come. The interview was one question and then they said they would call me when the background check cleared

Well i applied three weeks ago and got a call back from HR and they scheduled me a interview, waited about 20 minutes manager had no idea, they even had a interview & asked me about the first thing was my customer service skills and to explain a time i went above and beyond for a customer, explained the job to me, i was not told the job was part time, even though i clearly listed fulltime on my application and that's what made me decide to walk out, after i was told to wait for a HR associate to come and get me to finish the hiring process with HR, i thought about it and decided i rather stay with my fulltime job then work part time labor.
