> That's only true for a subset of programming languages, and it requires you to already know how to program in at least another language of the same family. Knowing Java will not help you with Haskell, but it will help you with C#.

In this context, to a large extent it holds. Yeah. It’s probably more true of mainstream languages roughly related to each other, but in an interview, you’re not testing for knowledge of syntax and keywords. You’re trying to test for ability to build and problem solve.

I share your concern about prompt “engineers” who don’t understand the underlying codebase, language or system. But I don’t know what to do about it in the context of a technical interview.
