I agree that the question needs improvement, it admits too much confusion unless there's a context. List is an ADT in Java and OCaml and some of the literature, an implementation in Python, C++ etc. Linked-list would have avoided that, although possibly suggests an answer.

Having said that, I'd be minded to look dimly on a candidate who tried to sidestep that question with 'but I use Python and they're the same there, so it's just a question of semantics' and did not try to clarify the question with me.
