>Have you actually written, in shipping code, a single-linked list or an elementary algorithm to operate on one? Yes, I have. Admittedly, I had to do it much more often when STL was a toy. But this is not the reason for this question, this is simple coding exercise, if a candidate can't do it without bugs in 10 minutes, there is nothing to talk about. Of course jobs not requiring writing C++, Java, C#, or Python code need different set of questions.
