The point isnt to give a simple answer, even if it's a correct answer. The point is show how much you know and how smart you are.

The question is framed to you as a way for you to show you know x, y and z and talk about x, y and z.

Even if a valid solution is just do a, that's great. But the interviewer has no idea if you actually know about x ,y and z do they ?

> The point is show how much you know and how smart you are.

I like that this sentence can be read both as a productive, well-meaning view on interviews, as well as a highly cynical one.

Also makes me wonder if the person will keep showing how much they know and how smart they are after they are hired, and if that is a good thing.
