What this question tests
Product design judgment: scoping a calendar feature inside an existing social product rather than reinventing a standalone app.
How to approach it
- Users: define who needs this, event organizers and attendees already using Facebook Events, not a Google Calendar replacement.
- Pain points: today's Events are scattered and hard to track alongside personal commitments.
- Prioritize: focus on aggregating Facebook Events (birthdays, RSVPs) into one view rather than full calendar functionality like meeting scheduling.
- Solution: a lightweight calendar surface showing RSVP'd events, birthdays, and group activities, with optional sync to external calendars.
- Success metric: RSVP to attendance conversion rate, and weekly active users of the calendar view.
- Confirm scope: whether this competes with Google Calendar or stays a companion view for Facebook-native events.
What a strong answer includes
- Scopes tightly to Facebook-native data, RSVPs and birthdays, rather than building a general purpose calendar.
- Proposes export or sync to Google or Apple Calendar instead of competing head-on.
- Defines a clear success metric, like a lift in event attendance rate, tied to Facebook's actual business interest in Events.
Common mistakes
- Designing a full standalone calendar app that duplicates Google Calendar.
- No tie back to existing Facebook Events data.
- Vague success metric unrelated to attendance or engagement.
Likely follow-up questions
- Would you build this as a new tab or integrate it into an existing surface?
- How would you handle users who do not use Facebook Events at all today?
