It's an example of how brain-dead the hiring process is for tech in general. Most of the jobs I've worked in my entire career have involved working with languages, not just frameworks, that I didn't know beforehand. I learned all of them and became good at them on the job. If you have a good grounding in programming fundamentals and you are reasonably productive then it's pretty easy to pick up any language in a short amount of time, especially now. I think part of this is that there is this common delusion that tech workers in hot fields (like silicon valley startups) have to all be rockstars or have to all have some exceptional level of expertise. And having those people on board is how you crank out software better and faster. The reality is that someone who coincidentally happens to have experience with whatever your current technology stack is may not have the highest level of overall expertise or talent that you truly need.
