I've introduced Clojure to my employer (very large gaming company), so I get to work with it a good amount. Some folks are using Scala on another team, too. Most folks are using Java or Go. Bringing FP to a company is tough, unless you're already senior and have a good amount of push.

I think a lot of the more senior devs who want FP have spent years writing OOP and procedural code. They did their time, so to speak. As a new grad coming in, you'll need to have reasonable expectations here. You'll likely need to do your time.
