Agree. Its far more valuable to see how a candidate approaches problems than some memorized recital show. I don't expect perfection, but if their reasoning is sound that becomes clear fairly quickly. I usually also include some imperfect questions purposely to see how they handle that. While we wish client projects were nice and clean with orderly data and tight requirements, the truth is that is rarely the case. It's useful to see how the candidate responds to those types of things. I had one gentleman argue with me about one of those questions claiming you would never see primary and foreign keys between tables not perectly match in the real world. Well when you are matching data from entirely disparate systems, you typically do. Anyway I digress.
