Applied online and went in person to see the hiring manager. I kept checking back with the hiring manager every 2-3 weeks. Be persistent. Keep bugging them and show them you are interested. I gave one of the hiring manager's my resume, and about a few days later I received a call for an interview the following saturday. The interview was conducted in a little room right next to the break room. One of the assistant manager's was in there along with a supervisor and they asked very basic questions like "have you had a job before?" "What is customer service to you?" and a couple scenario questions like "Suppose you had to run back to get an item and a few members stopped you to asked for an item's location. How would you handle that?" After that interview was finished, I received a call about a week later or so for another interview, this time with the warehouse manager. When I met with him, this was in his office. He was really cool and he welcomed me into his office and asked me calmly why I wanted to work there. "Why Costco? What drew you to here as opposed to some other place." I told him that I am very ethics focused--in school I studied philosophy and my area of interest was ethics--and I told him that I liked the fact that Costco was focused on ethics and treating its members and workers properly. After that he asked me some other basic questions like if I had another job, what other experience I have, where I went to school, etc. He was very easy to talk to. He offered me the job right at the end of the interview.

3 different interviews with different managers process took a while but actual interviews were quick and easy. Did have to call and follow up a lot in order to keep the process moving.
