I've never seen a job ad that was just about the language. Usually there's a language a domain (i.e. AI, video, telecom), and several frameworks or applications. The language is the easy part. Frameworks and applications can be huge learning curves. Domain knowledge is really the hardest. Taking someone who's been doing database CRUD apps with Rails and React and expecting them to pick up writing video codecs in C++ is really where the reach is.

I have recently found that video codecs (and other forms of modern compression) are indeed difficult to casually pick up in one's spare time, but if a company is willing to dedicate even a modest amount of an existing team member's time to training new hires I would expect this to go fine.

The weird thing is that almost no company does this (or, within each company, almost no team does this, and individual team leads or engineers may rebel by doing this and then be punished when perf comes around)
