Very few developers even trust themselves to vet the sorts of things this post is talking about. So our current level of in-industry interview training is going to make that a crapshoot. The general reason given for non-representative algorithmic whiteboard coding problems is "you can't trust anybody's experience." But those questions are themselves not resulting in production-ready code, so you're flying blind on "can figure out a quick way to solve a problem" vs "knows what to do to turn a quick solution into something that will last." And then there's a time-based calculation you have to make: hire fast and hope they'll learn on the fly, or slow down and delay until you find people you hope won't have to. You're hoping either way, after all. :)
