Except programming and engineering is about overcoming the unexpected. Adapt and improvise. Not everything is textbook and, at least this is my opinion, the better engineer is the one that can solve unexpected problems. You can really only judge that utilizing past experience. Canned, standardized questions similar to Mensa intelligence questions or any type of "brain-twister" puzzle are pretty crappy. Once you know the tricks they're applying to the question, they're easy to solve. But that's not the same as actually "figuring out" a real world problem.
