> There are enough young enthusiasts who will rewrite something to weird tech without asking This is a communication problem, and not something you can infer from a CV. I can't see why having experience with any particular language would be a bad thing—quite the contrary. There are concepts to learn from each language, and the more languages under an engineer's belt (particularly "weird" languages), the more open they are to novel solutions. The tool analogy works well: you would want someone who's familiar with an axe and a chisel, and not only a hammer. Someone thinking this is a bad thing shouldn't be making hiring decisions. It speaks more of the company, so OP probably dodged a bullet.
