IME it depends on the shop and it's own skill level. If you've got a bunch of devs with only experience in the tech stack the company is using, they'll be heavily selective for a match to their stack. If they've got a broad set of internal tools in a bunch of languages, they're likely selecting more broadly based on overall skill or the ability to get up to speed.
And I'm 100% with you there, learning a new place's codebase can often take as much or more time than learning a new language (at least if you've got experience with a couple of languages already). There's at least tutorials and guides for a new language, and there's rarely good docs and resources for the codebase.
