RAII is a good question to weed out inexperienced C++ programmers, but I don't think asking about SFINAE is a very good interview question, unless the job involves heavy template metaprogramming, and even then it is such an obscure name for a fairly intuitive concept ("yeah so the compiler will only use the template definitions that work") I am sure there are many people good at template metaprogramming that don't know the term. Edit: changed "incompetent" to "inexperienced" as it better reflect my opinion.

It's not a pure "if you don't know SFINAE you're out" but it gives you a very strong indication of which parts of the language they're actually familiar with (although maybe it's a little dated now), and for a lot of candidates you could go through a list of dozens of these acronyms and they wouldn't be able to reasonably identify any of them.
