Sam's Club interview questions

I interviewed in WA (where there are only three stores, state-wide). I found the interview very casual and comfortable. The woman (I will keep her name private) was very nice and welcoming. The only downside was she rambled on about membership upsales, giving me the impression that the location needed more upgraded memberships and doesn't have the staff comfortable to do so. I was only asked three questions. I was then given an employment offer, signed consent for my background check and given paperwork to take my drug test. I was told I had 24hrs to take my drug test and given instructions on the process. I worked for Walmart, 8yrs prior; only for 3 months (I left due to emergency circumstances, causing me to suddenly move three hour away). Unbelievably, that process was much harder. I was offered less than half the wage, had to wear a uniform and went through a 3 interview process at Walmart. Not to mention, Sam's is cleaner, more organized and not open 24-7. I mostly have experience in union grocery stores (I am journeyman) but I was offered more than what I desired hrly (with no union dues) and scheduling wise. I am quite content with Sam's. I should add I wasn't looking for more than 20hrs a week.
