Very straightforward interview with a supervisor and manager, reviewing your application. The next round is an interview with the assistant manager and that person getting to know you and seeing if your personality fits

Three rounds of interviews. If you're lucky, you'll do two rounds because two managers in the room are two interviews. Then the final interview is with the warehouse manager. Be on time; I cannot stress that enough, as Costco is a very time-sensitive type of position. You only have a three-minute grace period to clock in at your normal hours. Emphasize that you are very prompt and are ready to work through the probation period.
