The problem with interview questions like this is that it looks for code-monkeys. I'd maybe have questions like this if I were hiring an expert consultant to crank out some short-term JavaScript for me, but for filling a slot on the team....probably not....as there's really about 10 other things I'm more interested in (assuming they have the necessary technical chops, which I feel these questions don't really answer). "At this point, if the candidate is doing really well, I'll ask them to implement currying arguments." Why? If they've already proven enough tech knowledge to do the job, why continue to ask more questions that might/might not use to server your hiring decision? (It sounds like you'd continue a different direction if they couldn't implement with currying). EDIT: I'd probably not be really hiring a short-term consultant like this either, though, now that I think about it.
