Seems like you're completely missing the point of the interview question which is to see how someone would approach a problem, investigate its requirements, propose a solution, examine its drawbacks and how they would take feedback on that solution and its possible advantages and disadvantages.
I did not miss that. I was pointing out that glofish said he asked questions like these repeatedly to candidates, but he doesn't even understand the basics of the subject matter. That would not make for a good interview.
