It doesn't help that so many concepts on CompSci show up in different places under different names and labels. I haven't participated in technical interviews in a long time, but when I was asked to do it, I made it a point to throw as many lifelines as I could until I got a satisfying answer. For instance, if want to know if the person understands generics and they can't answer the question outright then I'll ask them about C++ templates. Similarly, if someone can't describe the term "idempotence" I'll ask them "can you tell me what makes a function pure". Mind you those terms aren't interchangeable but if you catch one it should be trivial to understand the latter.
