I've been to a few interviews with startups. Some of them didn't care about not having their language on the résumé while some of them did. The impression I got is, you can just tell which one of them are looking for a code monkey and which ones want you to take a bigger role of contributing as a software engineer.

Maybe. But it is a legit chance someone wants a software engineer but doesn't want to teach an entire stack to someome.

If you coded in C for your business and two identicAL in every way people applied.. one only knew ruby and one only knew C.. which do you hire?

If you ended up in that situation, obviously pick the candidate more familiar with your stack, but that's a hypothetical, hiring in this business is not generally characterised by a glut of qualified candidates.
