To be fair when a company says they use C++, it can mean anything from "C with classes" to crazy metaprogramming with almost automatic memory management. Since they have over 10 years experience, they are almost definitely in the former camp.

I would never utter the phrase "I know C++" because it can mean so many different things to so many different people, and I don't think anyone truly knows the whole language.

Not using templates nor smart pointers doesn't sound that bad to me(unless the entirety/majority of the codebase was written with them in mind), the duplication thing is more questionable.
