To succeed as a CDS (Club Demonstration Services) representative at Costco, you need strong interpersonal skills, basic food handling knowledge, and the ability to stand for extended periods, with high school education often required. On-the-job training covers food safety protocols and point-of-sale demonstration tools, while a food handler’s permit may be necessary in some locations. Outstanding customer service skills, enthusiasm, and the ability to engage shoppers positively set candidates apart. These capabilities ensure engaging product demonstrations, compliance with safety standards, and enhanced customer experiences—critical to driving sales for both CDS and Costco.
