I think you're over-indexing on the notion that someone has "mastered simplicity", when what's truly valuable is the ability to reduce that which is complex to something that is simple. Inherently, that requires the ability to grasp the complex, and so you interview by presenting something that is complex, and judge based on the simplicity of the solution.

I like very much the 'over-indexing' terminology. I agree that I may be improperly confusing the ability to write simple code with the ability to solve simple problems.
