Walmart Overnight Stocker interview questions

The managers introduced themselves (there were two). We reviewed my application and I signed off that the information was correct, the info that needed corrections I fixed. The both were taking turns asking questions along the lines of how I have dealt with past issues when I had to take on leadership roles. Even, when I had to go above and beyond in order to satisfy a customer etc.

I applied at the Kiosk and passed the assessment, that took almost 2 hours. I was called a month later to come in for an interview the next day. I arrived at 11am for an 11:15 interview, after about 30 mins a man came out took the person before me and said he'd "be back in a few minutes to take me back to the interview." A half hour later, an associate checked what was going on and said "someone would be right out to do my interview." After yet another hour(I've now been there for 2 full hours!!!) I told an associate behind the walmart.com services counter to cross my name off the list and that I was leaving because any company that would treat prospective employees that badly, I don't want to work for. Between the application, assessment, and the non-interview, it was a complete waste of almost five and a half hours out of my time to get absolutely nowhere. It makes me not want to even shop there if that's how they're going to treat there employees/interviewees.
