This seems like a pretty good idea on the surface. I'm curious how the SAT and ACT standardized testing in the US came into the position of almost de-facto standardized college entrance exam. On the other hand, I've wondered why a similar thing doesn't exist in the real estate industry for home inspections. A good inspection costs a lot of money, and it seems basically every serious buyer needs to pay for it themselves. Why doesn't the seller pay for one up front and share the results with interested buyers? Certainly there's room for corruption / cheating, so maybe that's why? The same concerns would apply for a standardized whiteboarding. Not to mention that some kind of interview would have to happen anyway just as a context for getting to know a candidate. Personally, I think it's actually good that this happens in a technical context and, as others have said, is not completely based on a verbal conversation.
