What this question tests

End to end product design skill on a complex, high volume marketplace with many traveler personas and monetization angles.

Confirm scope: web and app booking flow for flights, hotels, or the full trip planning experience.
Segment users: budget leisure travelers, business travelers, and families, since their priorities differ sharply.
Identify pain points: overwhelming search results, hidden fees, and difficulty comparing bundled options.
Prioritize solving search relevance and price transparency first, since they affect the largest segment.
Propose a solution: a guided search with transparent total price and a saved comparison tray.
Define success with booking conversion rate and post booking satisfaction as the core metrics.

Picks one traveler segment to design for deeply, such as budget leisure, rather than boiling the ocean.
Names a specific pain point, hidden fees at checkout, that is well known in the travel category.
Proposes a concrete feature, a total price toggle, not just 'improve UX'.
Sets an illustrative target, like a 5 percent lift in search to book conversion.

Tries to redesign the entire platform instead of a focused flow.
Ignores monetization tradeoffs like ad placements and affiliate commissions that fund the business.

How would you balance showing the cheapest option against Expedia's own margin?
How would you measure trust in the price shown at checkout?
How would this differ for a last minute business traveler versus a planned family trip?
