Metrics question

Given a situation where you are a PM for a TravelTech company, what is one metric that you would build for the product leadership team?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Tests focus and prioritization in metrics work: can you pick a single, high-leverage metric for leadership rather than hedging with a long list.

Clarify the product area within TravelTech: assume a booking platform (flights, hotels, or packages), since the right metric depends on where in the funnel the company is focused.
Consider what leadership actually needs: a metric that signals overall business health at a glance, not a granular operational metric better suited to a team-level dashboard.
Propose completed-booking conversion rate (searches or sessions that result in a paid booking) as the single metric, since it captures funnel health, pricing competitiveness, and product friction in one number.
Justify why this beats alternatives: raw traffic or sign-ups do not reflect revenue-generating outcomes, while booking conversion ties directly to both user experience and business results.
Note what it would be paired with as a guardrail, such as customer satisfaction or cancellation rate, so leadership does not over-optimize conversion at the expense of trip quality.
State how it would be tracked: weekly trend by channel (direct, OTA-referred) and by trip type, so leadership can see where the trend is coming from.

Picks one clear metric as instructed rather than listing five, directly answering what was asked.
Justifies the choice against alternatives (traffic, sign-ups) explicitly, showing why this one is the highest-leverage choice for leadership specifically.
Adds a guardrail metric to prevent a narrow optimization trap, showing systems thinking beyond the single number.
Specifies how it would be sliced (by channel, by trip type) so it is actionable, not just a vanity number.

Listing multiple metrics when the question specifically asked for one, missing the prioritization test.
Picking a vanity metric like total traffic that does not reflect business health.
No guardrail, risking an answer that could be gamed or misleading on its own.

What guardrail metric would you pair with this to avoid gaming it?
How would this metric differ for a last-minute booking product versus a planned-vacation one?
How would you present a decline in this metric to leadership?
