There is no scenario in which they would a) know the answer confidently enough they'd tell an interviewing prospective employee about it; b) be willing to do so; and, c) be stupid enough to do so.

I wouldn't have a clue. Short or knowing them socially, how would I know? Given they're 4 levels above me in the org (me->VP->SVP->CTO->BOD), I have zero reason to interact with them on any basis, let alone a social one.

If it's a public secret and it affects the company - then yes.

Of course they would rather not disclose such a thing to prospective candidates and it's rude to ask, so I dropped this question.
