Would you address the error and risk slowing things down or ignore it to keep the project or task moving forward?
Employers may ask this question (or something similar) to assess your integrity and determine whether your ethics and beliefs align with the company. Consider using your response as an opportunity to share your commitment to honesty and quality work.
Example: “I’ve always found it’s better to take responsibility for your mistakes—and work to correct them—to learn from your errors. When I worked as a barista, a customer asked for a soy latte and I accidentally made their drink using whole milk. While there’s a chance they may never have known, I knew my error could affect their experience. I promptly told my manager, remade the drink and apologized to the customer for the wait. The customer was satisfied, and my manager thanked me for doing the right thing. From that point forward, I paid special attention to drink ingredients.”
