"People like you are mostly just lip service."
Err, ok? I'd argue that the interviewer's job is to determine that. If the interviewer just wants to banter back and forth on specifics of languages and whatnot, that's fine, but in the big picture I don't find it helpful.
So to use an example, if you want to hire someone to build a deck onto your house, do you quiz the person on Craftsmen hammers, Stanley measuring tapes and Black & Decker saws? I wouldn't. I'd ask what similar projects they've done, what problems they've run into, etc.
Call it lip service, but I think the big picture is more valuable. Specifics of language syntax & conventions is OK, but knowing how to wield the tools is far, far more valuable in my opinion.
