The Danger Zone: Top Reasons Candidates Fail
Based on our database of pubX interview outcomes, avoid these common traps:
- Assuming publishers will fully trust a black-box AI model without manual override mechanisms
- Focusing solely on eCPM increase while missing drop-offs in total ad fill rate or impression volume
- Designing a passive analytics reporting tool instead of an automated workflow engine
- Failing to build in guardrails that prevent misconfigured dynamic floor prices from dropping bid rates to zero
