Product design question

How would you map the ocean?

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

Ability to scope an ambiguous, technically hard, non-consumer product problem.

Confirm whether 'mapping' means bathymetric seafloor depth or surface and ecosystem mapping.
State the chosen interpretation: bathymetric mapping, the common reading of 'mapping the ocean'.
Identify who needs this data: shipping companies, researchers, and telecom cable layers.
Propose combining satellite altimetry for rough global coverage with sonar from ships and autonomous underwater vehicles for detail.
Prioritize shipping lanes and coastal areas first, since they have the highest commercial value.
Define success as percent of the ocean floor mapped at a usable resolution.

States the chosen interpretation explicitly instead of guessing silently.
Names real methods, satellite altimetry, sonar, and AUVs, rather than vague 'use sensors'.
Prioritizes by commercial and safety value instead of mapping uniformly.
Gives an illustrative baseline, e.g. notes only a small fraction of the seafloor is mapped at high resolution today.

Not clarifying which kind of 'mapping' is meant and going in the wrong direction.
Ignoring cost and feasibility, proposing full high-resolution coverage of the whole ocean at once.
