This question assesses your analytical abilities as well as your capacity for planning, developing strategies, establishing measurable objectives, and understanding quality control processes. To respond effectively, consider these essential points: Clarify your interpretation of "bad ads." This may refer to advertisements that breach Meta's advertising guidelines (such as spammy, misleading, or inappropriate content), low-quality ads, or those that simply underperform. Set objectives. This will likely require a multi-layered approach that includes prevention (systems designed to filter out or stop bad ads from being shown), monitoring (techniques for identifying and removing bad ads after they have been displayed), and continuous improvement (strategies to learn from bad ad incidents to avoid future occurrences). Describe how you will assess success. This could involve quantitative measures (e.g., a decrease in the number of bad ads, an increase in ad performance) or qualitative assessments (such as user feedback and adherence to policies).
