I was once in the position of Mark Dominus. I had spent years of using Haskell for recreational programming and wrote a book using the subset of Haskell that I personally use (you can get a free copy at https://leanpub.com/u/markwatson https://leanpub.com/u/markwatson by setting the price to free). About six years ago I decided to apply for Haskell jobs at Standard Charter and Facebook on Haskell teams with well known people in the field. Both groups said that I was an interesting candidate and suggested getting another Haskell job for a while, and then reapplying. I did end up consulting remotely for a startup in India writing Haskell but that job was short (about 6 weeks) because I was in the process of getting hired at Capital One to manage a deep learning team.
