It's probably too late to come back to this thread, but no, I'm not talking about the narrower but more common complaint about algorithmic questions. I think the entire approach of constant proving is misguided. There are lots of other ways to do this with lots of prior art in other industries. I believe we have landed on a poor but self-perpetuating solution. What we do to hire is akin to what they do in the performing arts, but our work is entirely dissimilar.

Do mechanical engineers draw up a design for a valve or something at every job they apply for?
