Yeah, I also found it interesting. Curious what's their hiring pipeline for Clojure devs? I know a couple of startups that picked Clojure ended up having troubles finding good devs.
Well, I found it found it hard to hire Clojure developers too. But I addressed it by hiring good to competent developers, asking if they are willing to learn Clojure and then getting them to implement a test project in Clojure as part of the interview process. Since Clojure is syntactically not huge, it is easy to pickup, for good developers. That's my hiring pipeline. ;)
Out of interest, roughly what percentage of candidates agreed to take on the project?
A fairly high percentage. I guess filtering for candidates who are polyglot developers comfortable in more than one language helps. The fact that Clojure is used acts as a filter for self-driven and "better programmers" [1].
