I'd also note that one of the reasons I prefer doing such things in person is (in addition to not taking up too much of the candidate's free time) that if they misinterpreted something or are going off in the wrong direction or something, I can correct them right away instead of letting them waste a bunch of time. This also lets you see how they tend to interpret instructions and take criticism and corrections.
It's also IMO a failure mode for a candidate to get a simple task that should be done in 5-20 lines of simple code and try to build some over-complex super-modular and extensible thing for it, and resisting correction on it not needing to be that over-engineered.
