Model answer
Isolate before diagnosing. Segment by platform, geo, payment method, new-vs-returning, and traffic source — the 8% is almost never uniform. Once you find the concentrated cohort, ask engineering for a deploy log covering the last 24 hours.
What great candidates actually do
- First question: is analytics itself broken? Rule out instrumentation.
- Overnight drops correlate with deploys, third-party outages, or a competitor promo.
- Don't announce a root cause until you can explain 80%+ of the drop.
Traps to avoid
- Naming the solution before the problem — always restate the goal in one sentence first.
- Answering without structure — pick a framework out loud, then execute it.
- Skipping the trade-off — every strong answer names what you would NOT do and why.
