My local Costco had a job fair as they were looking to hire seasonal workers for the holidays. I interviewed with two different supervisors. The questions were very generic, more about team specific things and how you value customer service and what not. After this interview, I went to meet with the store manager who talked to me for 10 minutes and told me what he expected of me. I then had a drug test and after the drug test results, they gave me my hours. It was a pretty smooth process.
