Product design question

What privacy feature would you add to WhatsApp?

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 targeted, scoped feature ideation for a mature, well-known product rather than a full redesign.

Identify a real unmet privacy gap, for example custom last-seen and online-status lists rather than an all-or-nothing toggle.
Pick one feature: a per-contact exception list applied consistently to last-seen, profile photo and status.
Design it as a settings toggle to build the exception list, applied consistently across all three privacy surfaces at once.
Define success as adoption rate of the granular setting and a drop in privacy-related support complaints.

Proposes a specific, buildable feature, a granular per-contact privacy list, instead of a vague more-privacy answer.
Explains why an all-or-nothing default frustrates users, for example hiding status from one contact but not everyone.
Applies the setting consistently across last-seen, photo and status rather than as three disconnected toggles.

Proposing something WhatsApp already mostly has without adding a genuinely new angle.
Being too vague, such as just saying add more privacy options.

How would you prevent this from being used to awkwardly exclude specific people?
How would you measure if this actually increases trust in the app?
