The Costco interview process was great, everyone at the Schaumburg, IL store location was very friendly and kind. There was a quick drug test before the initial interview process. A cotton swab of the mouth and gums was the means of the drug test. After my confirmation of my clear drug test a group interview was held with the district manager. He was very kind and informative about the company and its' policies. Lastly was a group interview with the district manager and 2 assistant store managers. This last interview was meant to familiarize me with the store managers and the specific store policies.
