Explanation
Hint: Identify the requirement first, then choose the approach that addresses the main constraints, trade-offs, failure modes, security, cost, and verification.
Correct answer: I would approach “What questions should you ask before designing a system from an ambiguous interview prompt?” by clarifying the requirements first, then using these considerations: in a real interview, i would not jump straight to a technology choice. for “what questions should you ask before designing a system from an ambiguous interview prompt?”, i would first clarify users and primary use cases. then i would estimate scale, traffic, data size, and growth and ask about latency, availability, and consistency. i would also clarify security, compliance, and failure requirements. finally, i would ask about cost or delivery constraints. i would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.. I would state my assumptions and defend the trade-offs rather than presenting the choice as universally correct.
Why the alternatives are weaker:
- Starting with service names
- Asking only scale questions
- Failing to state assumptions
What the interviewer is testing
- Problem framing
- Requirement discovery
- Communication
Common Mistakes
- Starting with service names
- Asking only scale questions
- Failing to state assumptions
Interviewer Follow-ups
- What assumptions would you clarify before committing to the design?
- What changes if the scale, reliability target, security requirement, or budget changes?
- What is the biggest failure mode in your proposed approach?
