The Costco Code of Ethics — The Four Principles That Run Everything

Costco's Code of Ethics is a four-principle document that functions as the company's operating system — not a marketing slogan. It's the lens behind nearly every behavioral question, and candidates who know the principles in order, understand the priority logic, and can speak to how the principles connect outperform those who don't. This module decodes the Code of Ethics and shows how to weave it into interview answers.
