Product design question

How can the service of Facebook Messenger be improved?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Tests product sense for a mature, high-usage messaging product, picking one specific friction point over generic feature additions.

Clarify scope: assume the core one-to-one and group chat experience for everyday users, not the business messaging surface.
Segment users: heavy daily chatters, and users who mainly use it for occasional group coordination.
Pick one pain point: managing message overload in busy group chats, missing important messages amid casual chatter.
Propose a lightweight important flag or smart-thread summary surfacing messages needing a response, without requiring users to mute or leave groups.
Address the trade-off: AI-based summarization must be transparent and dismissible, since users may distrust an algorithm judging personal conversations.
Define success: reduction in reported missed-message complaints, and engagement with the summary feature in high-volume group chats.

Picks a specific, common pain point, group chat overload, rather than a broad list of feature requests.
Proposes a concrete, opt-in mechanism, a smart summary, rather than forcing a new default behavior on all chats.
Addresses trust explicitly, since summarizing personal conversations carries more sensitivity than a work inbox.
Defines success with both a complaint-reduction metric and a feature-adoption metric.

Suggesting broad, unrelated feature additions instead of solving a real usage friction.
Ignoring the trust and privacy sensitivity of AI summarizing personal messages.

How would you test this without users feeling surveilled in their personal chats?
How would this differ for large group chats versus close friend threads?
