What this question tests
Tests product improvement thinking on a mature, well-known feature: identifying a specific weakness in Timeline (profile history) and proposing a scoped, defensible fix.
How to approach it
- Clarify what Timeline refers to: the chronological profile view of a user's posts, photos, and life events over time.
- Identify the user and pain point: users revisiting old memories or friends trying to learn about someone find Timeline cluttered and hard to navigate, mixing trivial posts with meaningful life events.
- Prioritize the pain point: surfacing meaningful moments (life events, milestones, most-engaged posts) over chronological noise is the highest-value fix, since 'scroll through everything' doesn't scale for long-time users.
- Propose a solution: an improved 'Highlights' view that auto-curates significant posts (life events, high-engagement photos, tagged milestones) with a toggle to switch to full chronological view.
- Address a trade-off: auto-curation risks surfacing something the user doesn't want highlighted (an old breakup post), so add easy per-post exclude controls and let users manually pin favorites.
- Define success: time spent and return visits to friends' Timelines (a proxy for 'getting to know someone' value), and use rate of the Highlights toggle.
What a strong answer includes
- Names a specific, well-understood weakness (chronological noise burying meaningful moments) rather than vague 'make it more modern' feedback.
- Proposes a concrete, scoped feature (auto-curated Highlights view) rather than a full Timeline redesign.
- Addresses the real risk of auto-curation surfacing unwanted content, with a specific mitigation (exclude controls).
- Defines success tied to the actual use case (getting to know someone via their profile), not generic engagement.
Common mistakes
- Proposing a full visual redesign with no clear user problem being solved.
- Ignoring the sensitivity risk of auto-surfacing old or unwanted posts.
- No distinction between the profile owner's experience and a visitor's experience, which differ meaningfully here.
Likely follow-up questions
- How would you personalize what counts as a 'meaningful moment' per user?
- How would you handle privacy settings interacting with Highlights?
- How would you measure if this feature increases or decreases posting behavior?
