What this question tests
Tests metric design for a specific sub-audience product, distinguishing it from generic platform-wide engagement metrics.
How to approach it
- Clarify Campus's goal: helping college students connect with their specific school community.
- Choose a north star: weekly active students engaging within their verified school community, not overall DAU.
- Build supporting metrics: posts and comments within school-specific Groups, event RSVPs, connections made.
- Add a guardrail: verified student signup rate and low fake-account rate, since trust depends on real students.
- Segment by school size and class year, since a freshman's needs differ from a senior's.
- Define a leading indicator: percentage of new signups taking a meaningful action in week one.
What a strong answer includes
- Distinguishes Campus's north star from generic platform engagement, since it serves a narrower community.
- Adds a trust and verification guardrail specific to Campus, which matters more here than platform-wide.
- Segments by class year, recognizing freshmen and seniors want different things.
Common mistakes
- Reusing generic platform DAU as the success metric without adapting it.
- No guardrail around fake or non-student accounts.
Likely follow-up questions
- How would you verify a user is really enrolled at that school?
- How would success differ for a large public university versus a small college?
- What would tell you Campus is cannibalizing the main app instead of adding value?
