Applied online and got called about 2 days later for an interview. On the day of, I was interviewed by 2 managers. The questions were pretty typical. Nothing too hard. Afterwards they told me they would give me a call if I made it to the third interview ( this interview counted as 2 since 2 managers were present) and if not, they would send me a letter in the mail saying I didn't make the cut. They called about 3 weeks later for the third interview with a higher up manager. The third interview was not really an interview but more of explaining to me what it's like working as a seasonal employee. They then do the swab drug test and background test and once you pass those you're good.

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.
