What this question tests
Tests the ability to define a clear problem statement for a real, known feature, separating the user problem from the feature's mechanics.
How to approach it
- State the feature in question: WhatsApp's disappearing messages, which auto-delete chats after a set time.
- Identify who this serves: users sending sensitive information (financial details, personal topics) worried about messages persisting indefinitely on multiple devices.
- Frame the problem statement as a gap: users currently have no way to limit how long their messages remain accessible once sent, creating a lingering privacy and clutter concern.
- Distinguish this from full end-to-end encryption, which protects messages in transit but not from being stored indefinitely on a recipient's device.
- Note the secondary problem it addresses: chat clutter and storage bloat from years of accumulated messages.
- State the problem in one clear sentence rather than describing the feature's settings and mechanics.
What a strong answer includes
- Separates encryption (in-transit protection) from disappearing messages (retention control), showing precise understanding of the actual problem.
- States the problem from the user's perspective, lingering privacy risk, not from the feature's technical description.
- Names both the primary driver, privacy, and secondary benefit, reduced clutter, showing full problem scoping.
- Avoids inventing statistics about adoption or usage that aren't verifiable.
Common mistakes
- Describing the feature's UI and settings instead of stating the underlying user problem.
- Conflating this with end-to-end encryption, which solves a different problem.
- Inventing unverifiable adoption statistics.
Likely follow-up questions
- Who is this feature not designed for?
- What's the risk of a recipient screenshotting before a message disappears?
- How would you measure if this problem is actually being solved?
