Your story matches my experience, but it always makes me think, why did this person want to work with you in the first place?

A great Haskell programmer (generally speaking) is going to be a culture misfit in any Java, C#, golang, etc shop. I know because I've been that miserable bastard who loves functional programming working with Java devs who don't know anything about FP and couldn't care less. To be clear I'm not saying you can't find a compatible Java shop (I actually did find a startup with a lot of Java devs who appreciated FP and used much of it in Java, and that was pretty great honestly), just that the odds are highly against you.

My biggest advice to people who like FP is: Find a job in a language like Clojure, Elixir, Scala, etc. There are a lot more jobs than you'd think. But if you can't, Ruby and Javascript/Typescript can be pretty close depending on where you go. Talk to existing devs and see how feel about FP in general before you join though!
