What this question tests
Tests metric-tree design for a coordination and utility feature whose value is realized off-platform when a real event happens.
How to approach it
- Clarify the goal: Facebook Events helps users discover and coordinate attendance at real-world or online events, so success means events actually happen and are well-attended.
- Set the north star as RSVP-to-attendance conversion where measurable, or event creation-to-fill rate.
- Add supporting metrics: events created per week, invite-to-RSVP conversion, and repeat event creation by the same host.
- Add guardrails: spam or fake event rate and event cancellation rate.
- Segment by event type, public and community events versus small private gatherings, since usage patterns differ.
What a strong answer includes
- Picks RSVP-to-actual-attendance as the truer north star instead of surface metrics like event page views.
- Correctly identifies that Events' value is realized in the real world, not just on-platform.
- Separates organizer-side and attendee-side metrics rather than collapsing them into one number.
Common mistakes
- Measuring only event creation count or views without connecting to actual real-world attendance.
- Ignoring spam or fake event issues as a guardrail.
Likely follow-up questions
- How would you measure actual attendance when it happens off-platform?
- How would you detect and handle spam or fraudulent event listings?
