Walmart Cashire interview questions

I went in for interview at walmart and the person who was suppose to be interviewing was not there. They called in different person to interview me and the questions were not what I really expected. The same day I got called in for another second interview.

filled out application online, then i had to call several times for them to give me an interview because they have alot of people applying so you have to put yourself out there to get noticed , then they ask questions like " describe a time at when you showed outstanding customer service", then if you pass that part you go for a drug test and once they get the results back then thhey call you for orientation.
