It could be a great question if you clarify the goals. As it stands it’s “here’s a problem, but secretly I have hidden constraints in my head you must guess correctly”.
The OPs desired solution could have been found from probably some of those other candidates if asked “here is the challenge, solve in most McGuyver way possible”. Because if you change the second part, the correct answer changes.
“Here is a challenge, solve in the most accurate, verifiable way possible”
“Here is a challenge, solve in a way that enables collaboration”
“Here is a challenge, 6TiB but always changing”
^ These are data science questions much more than the question he was asking. The answer in this case is that you’re not actually looking for a data scientist.
