IDFA Changes On Ad Companies

This problem tests understanding of how platform policy changes can reshape the economics of digital advertising, especially in TMT. A candidate needs to think through what IDFA is used for, how user consent affects data collection, and why reduced tracking can make ad targeting, attribution, and measurement less effective. Interviewers ask questions like this to see whether you can connect a product decision by a major platform to revenue and margin implications for advertisers, publishers, and ad tech companies, and whether you can reason about second order impacts on monetization and user privacy without simply restating the policy change.
