I don't know how serious you are being, but the purpose of the interview question may not have anything to do with the job whatsoever, or it may.

Either way, questions of this nature are intended to filter out people who are not interested in getting to the root of a problem, and solving that problem practically.

The interviewee should be looking to determine constraints, limitations, expectations, requirements, use cases, problem scale.

The interview for any job should be looking for someone looking for those things.

In what way would any job that requires critical thinking be considered boring?
