Design a Recommendation Engine for Airbnb Experiences
Design a feature that recommends non-stay related 'Experiences' (tours, classes) to users who have already booked accommodation. Focus on placement and timing.
Why Interviewers Ask This
Interviewers ask this to evaluate your ability to balance user value with business growth in a multi-sided marketplace. They specifically test if you can identify the right timing for cross-selling non-core services without disrupting the primary booking flow, demonstrating strategic prioritization and deep empathy for the traveler's journey.
How to Answer This Question
1. Clarify Objectives: Define success metrics like click-through rate (CTR) on experiences versus potential friction in the booking funnel. 2. Map the User Journey: Identify specific touchpoints where a guest is most receptive, such as post-confirmation or pre-check-in, rather than during the initial search. 3. Segment the Audience: Differentiate between leisure travelers seeking fun and business travelers needing efficiency; tailor recommendations accordingly. 4. Design the Placement Strategy: Propose specific UI locations, such as a dedicated 'Plan Your Trip' tab in the app or a contextual modal after payment, ensuring it feels native to Airbnb's design language. 5. Address Risks: Discuss how to handle data privacy and avoid overwhelming users with irrelevant suggestions that could damage trust.

- Segment recommendations based on property type and user intent to ensure high relevance
- Define clear success metrics balancing revenue uplift against user experience friction
- Leverage existing data signals like browsing history to personalize the initial suggestion set
- Design the UI to feel native and helpful rather than promotional or disruptive
