Walmart Programmer interview questions

Walmart paid for my Greyhound bus ticket that took me from Melbourne, FL to Atlanta, GA to be interviewed. Had 4 back-to-back interviews. Watched as others with me had 2 and then were dropped. At the end of the 4th interview, I was offered a position with starting pay. There was not much room for negotiation, but I was able to ask for a slightly higher pay than they initially offered and then accepted it.
