What this question tests
Product sense for a location based, self serve experience that must work without a live guide.
How to approach it
- Clarify the target traveler: solo tourist, family, or history buff, and whether this ships standalone or inside Google Maps.
- Map the journey: pre trip planning, in the moment navigation, and post walk sharing.
- Identify the core pain point: tourists get lost, miss context on landmarks, or find generic audio guides boring.
- Prioritize in the moment engagement since that is where most time is spent.
- Propose GPS triggered audio stories, curated routes by theme like food, history or architecture, and offline map caching.
- Define success as tour completion rate and average landmarks engaged with per walk.
What a strong answer includes
- Segments tours by interest, for example a 90 minute food history route versus a 30 minute highlights route.
- Addresses offline reliability since tourists often have no data plan abroad.
- Uses a concrete number, for example assuming 40 percent of started tours are completed.
- Considers monetization through local business partnerships, like a cafe offering a discount at a tour stop.
Common mistakes
- Assuming all tourists want the same pace or depth of content.
- Ignoring GPS accuracy issues in dense urban areas with tall buildings.
Likely follow-up questions
- How would you source and verify the tour content for a new city?
- How would you measure whether the tour improved the visit versus a paper map?
