I applied online and received a phone call requesting an interview. I arrived on the appointed day and was asked to request certain names for the interview. The person was not there and another person did the interview while someone else sat in and recorded things. The questions were all about experiences I'd had which might make me qualified for work at Costco. Things like "Describe a time when you had to deal with a difficult coworker." "Tell us a time when you showed leadership." All of these I found easy to answer because I work well with a story format. There were no trick questions and the interviewer made me feel pretty comfortable. I received a call later saying they would like to interview me again, and I arrived for my second interview not sure what I was doing or why, but I met the store manager who gave me another interview, which centered tightly around "Why do you want to work for Costco in specific?" "What do you expect to get out of this?" "What are your goals for pursuing this career path?" "Are you planning to try for a supervisory role in our company?" I got a call a few days later telling me that they were "Interested in moving forward with the hiring process" which was when I was asked to take the drug test and when the results came back from that a week later, they officially offered me the job and assigned me to an orientation day.

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.
