What this question tests

Product design for an easy, well trodden use case, testing whether the candidate can still find a differentiated, specific angle.

How to approach it

  1. Identify the user: extended families, often spanning tech-comfortable younger members and less tech-savvy older relatives, wanting to stay in touch.
  2. Name the pain point: existing video chat apps require the least tech-savvy family member (often an elderly grandparent) to successfully initiate or answer a call, which is a common failure point.
  3. Design around that constraint: default to auto-answer or one-tap answer for trusted family contacts, minimizing steps for the least tech-savvy user.
  4. Add a differentiator: scheduled or recurring family video calls (like a standing Sunday dinner call) that both sides can join with minimal setup each time.
  5. Prioritize the simplified answering flow first, since call failure due to a confused elderly user is the most common real world breakdown point.
  6. Define success as call completion rate (started calls that connect successfully) and repeat usage among older family members specifically.
