> an interview that clearly is meant to be "closed book," I am not sure that is clear. It seems the expectation was not "closed book", but "never opened a book before, not even in the past": "It's tough to determine if the candidate breezed through the question because they're actually good or if they've heard this question before." Clearly the interviewers were looking not for knowledge, but for uncanny ability. How well was that communicated to the interviewees? It is not cheating if the rules of the game are not defined.
