What this question tests
Incident response and root-cause thinking under pressure, checking you can triage a live metrics drop methodically.
How to approach it
- Acknowledge the urgency and first confirm the drop is real, not a reporting or dashboard bug, by cross-checking a second data source.
- Segment the drop, checking whether it is isolated to a specific advertiser type, geography, ad format, or platform to narrow the search space.
- Check for recent changes around the 10PM timeframe, such as a deploy, configuration change, or third-party dependency update that could correlate.
- Consider both technical causes, like an API or pipeline failure, and policy causes, like a new content review rule blocking more ads than intended.
- Prioritize the most likely and fastest-to-verify hypothesis first, typically a recent deploy or config change, before pursuing rarer explanations.
- State the immediate next step, alerting the right team based on findings and communicating impact and ETA to stakeholders while investigation continues.
What a strong answer includes
- Starts by ruling out a false alarm, checking dashboard integrity, before deep investigation, which experienced responders do first.
- Segments the drop methodically, by advertiser, geography, or format, rather than guessing at a cause blindly.
- Names a concrete, most-likely first hypothesis, a recent deploy near 10PM, and explains why that's the fastest lead to check.
- Balances technical and policy explanations, showing awareness that ad publishing failures aren't always engineering bugs.
Common mistakes
- Jumping to a fix before confirming the drop is real and segmenting where it's occurring.
- Only considering technical causes and ignoring policy or content review changes.
- Not communicating status to stakeholders while still investigating.
Likely follow-up questions
- What would you do differently if the drop had started gradually instead of suddenly at 10PM?
- How would you prevent a similar issue from happening again?
