What this question tests

Product sense for a smaller, mature feature, finding a real gap in a well known but rarely reconsidered flow.

How to approach it

  1. State the current experience, the platform reminds users of friends' birthdays and prompts a quick post on their wall.
  2. Identify the gap, birthday wishes are often generic and low effort, and the feature does not help users give something more meaningful when they want to.
  3. Propose an improvement, surfacing shared memories, photos, or a suggested personalized message based on recent interactions with that friend.
  4. Consider the opt in and privacy angle, not everyone wants birthday reminders shared publicly, so respect existing privacy settings.
  5. Define success metrics, percent of birthday reminders resulting in a post or message, and qualitative feedback on message personalization.
