Product design question

Design an innovative chat feature.

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 differentiated ideation within an extremely saturated category, requiring genuine novelty grounded in a real user pain point.

Pick a specific Meta messaging surface and a specific underserved use case rather than chat in the abstract.
Identify the pain point: group chats with many participants become noisy and hard to follow when planning a trip or coordinating an event.
Design an AI-assisted thread summary and action-items feature that surfaces decisions and tasks from a long group chat, plus inline polls tied to a specific message.
Prioritize the summary and action-item feature since group-chat overload is a widely felt, underserved pain point versus incremental sticker additions.
Define success as reduced catch-up scrolling time, engagement on inline polls, and group chat retention.

Picks a genuinely underserved pain point, group chat information overload, rather than a superficial novelty like a sticker pack.
Ties the AI-summary idea to a measurable proxy for the real problem, catch-up time, instead of vague engagement.
Grounds the idea in one of Meta's actual messaging products rather than staying abstract.

Proposing surface-level novelty like new emoji or filter features that doesn't address a real underserved pain point.
Not grounding the idea in one of Meta's actual messaging products.

How would you ensure the AI summary is accurate enough that users trust it over reading the full thread?
How would you handle privacy concerns with AI processing message content?
