Yep they could but companies usually don't do it.

I've done it. OOP is OOP, there are only different flavors.

I wonder to what extent an OOP person would be able to do a Haskell job (or a similar functional language).

Anyone can learn a language. The .Net framework and the related ecosystem is huge. I’ve done front end work maybe a decade ago, I still do backend JavaScript and I know the basics of web technologies. But anyone would be a fool to hire me if they wanted a front end developer.

Even if I knew Java that doesn’t mean I could just jump in and start doing Android development.

I remember jumping in and doing Spring Boot. I knew Java. It went well, it helped that I knew about NodeJS and Django.
