Google's “Director of Engineering” Hiring Test

I've been at Google for five years as a SWE and I've been interviewing for 3 of those. I'd fail this pop quiz.

This strikes me as bizarre and inconsistent with all the practices I'm aware of. The idea that we'd ask anyone this stuff, let alone director candidates, strains belief.

The only way this makes "sense" is if you already have the candidate (or pool of H1-B candidates) you want in mind, but have to prove you opened up the position to the general public first.

I know some companies do this, but this is Google. There's no incentive for them to hire H1-B's if a equally qualified American citizen is available, since they are going to pay equal salary.
