What this question tests
Product sense on picking two concrete, well justified features for a mature messaging app used daily by billions.
How to approach it
- Segment by a specific persona, like the candidate themselves, someone managing family group chats and casual friend chats.
- Identify one real pain point: scheduling plans in group chats requires switching to another app or scrolling through messages.
- Propose feature one: an in-chat poll or plan scheduler that turns a message into a shared event with RSVPs.
- Identify a second pain point: hard to find a specific photo or document shared months ago in a busy chat.
- Propose feature two: smarter media search using on device recognition of dates, people, or content type.
- Define success as usage rate of the scheduler in group chats and search success rate for the media search feature.
What a strong answer includes
- Grounds both features in specific, relatable pain points rather than generic ideas like better themes.
- Chooses features that fit WhatsApp's privacy first, lightweight positioning, for example on device search rather than cloud based.
- Gives an illustrative number, for example assuming 10 percent of group chats use the scheduler within a month of launch.
- Considers WhatsApp's encryption constraint, meaning any smart feature must work without server side access to message content.
Common mistakes
- Proposing features that require server side content access, which conflicts with WhatsApp's end to end encryption.
- Suggesting features WhatsApp already shipped, like polls, without differentiating the proposal.
Likely follow-up questions
- How would you build smart search while preserving end to end encryption?
- How would you prevent notification fatigue from the new scheduling feature?
