What this question tests
Growth-lever thinking for an engagement metric, balanced against the risk of low-quality engagement.
How to approach it
- Clarify whether the goal is comments per post or the percent of posts that get any comments.
- Break into levers: prompt design, visibility of the comment box, notification nudges for replies, and content type.
- Pick 1 to 2 levers to prioritize, e.g. a suggested-question prompt under posts and better reply notifications.
- Note the risk of incentivizing low-quality or spam comments if over-optimized.
- Define success as comments per post excluding removed or spam comments.
- Note which post types would benefit most from the change.
What a strong answer includes
- Distinguishes comments-per-post from percent-of-posts-with-comments, since the fix differs.
- Proposes a concrete lever, e.g. a suggested reply or question prompt to lower the barrier to commenting.
- Flags the spam and quality risk of over-incentivizing comments, with a removed-comment-rate guardrail.
- Considers notification nudges for replies to re-engage commenters into threads.
Common mistakes
- Proposing to 'add gamification' or 'notify more' without a quality guardrail against spam.
- Not clarifying which comment metric is actually meant.
Likely follow-up questions
- How would you prevent this from just increasing spammy, low-value comments?
- Which post types would you target first?
