Random fun idea: pair whiteboarding, have one of the reviewers start improvising a solution (or put on a show of not having done it dozens of times before) and see how the candidate will contribute. If the problem is not one of the standard ones (that will be perfectly memorized by desperate candidates, while rightfully confident ones may struggle), it will demonstrate understanding, not the irrelevant ability to sequentially write out code in an unfamiliar medium. After all, you probably don't want to hire those who have already been rejected so often that they can code on a whiteboard as if they did it all day.
