Costco Wholesale Programmer/Analyst interview questions

I filled out an online application, and called the store hr... there is no hr really and they said if they were intrested they would call. They didn't I called agian and finally spoke to someone they took my information and never called. I flew from Seattle to IL just to try and get an interview I got it but I had to do that extreme move to get it. I got the interview right then and there and the job offer. It seemed I had to push and push to get in, but once you have the interview set ujp it's pretty fast and they drug test you in house so the results are right away.
