I don't know if I would hire like this, but I do think a lot about the current hiring landscape is pretty broken, so maybe I should! I expect an employer needs a certain amount of cachet before being able to do this or anything else similarly left-field.
Side note - I started down two paths of significant new learning early last year: Security & Elixir / BEAM. I love Security Cryptography Whatever and had no idea you crossed over into the Elixir world (fly.io). Cool!
