I'm absolutely baffled by some of the comments here. This is more akin to learning a language and learning grammar structures in a language. Once you have mastered the language you simply don't care about the linguistic structures. When you learn english you learn everything about verb placement, sentence composition and a whole lot of other things. Now, when you ask me about the meaning of grammatical structures I only know some of them because I'm learning Chinese and Japanese, but they're completely irrelevant to me when I'm thinking about anglosaxon or roman language. Worse yet, most of those structure I wouldn't be able to associate or name nowadays.
There is a reason why recent graduates perform better at these interviews than seasoned engineers. Even for computational math where you have all the basics of calculus 1-3 and bunch of other things where you have to prove the theorems in the exams it doesn't mean you recall all of it forever. It's like saying if you really know how to use a fork you create one yourself.
