What this question tests

Whether the candidate can set a clear goal and matching metrics for a lightweight social feature inside a messaging app.

Clarify the goal: polls likely aim to increase engagement within group chats and give users a lightweight way to make decisions together.
Define adoption metrics: percent of active groups that create a poll monthly, and polls created per active group.
Define engagement metrics: vote participation rate (percent of group members who vote) and time to poll resolution.
Add a downstream metric: whether polls correlate with increased message activity in that group afterward, as a sign of genuine utility.
Set a guardrail: complaint or spam-report rate for polls used to harass or pressure group members.

Separates poll creation (adoption) from vote participation (engagement quality), since a poll no one votes on isn't a success.
Ties polls to a downstream lift in group chat activity as evidence of real added value, not just novelty use.
Includes a guardrail against misuse, such as repeated low-value polls annoying group members.

Measuring only poll creation count without checking whether members actually vote.
Ignoring the risk of the feature being used to spam or pressure group members.

How would you know if polls are cannibalizing regular group conversation instead of adding to it?
What would make you consider this feature a failure after three months?
