It also really bugs me when I've put more time into reporting an issue or setting someone up for success than they've spent working on a solution.

You would know best, but it struck me that one reason to skip parts of a take-home interview assignment is that it was taking far longer than it "should". A sufficiently senior candidate should have noted this but (I'm feeling charitable towards junior candidates this lazy Sunday afternoon) maybe that's something that's a reasonable thing for them to learn in a real job.
