I'm a bit surprised to hear this, I thought Clojure shops would be better than this. It was must hard to find any candidates and they're still doing the stupid leetcode interview style? Are these companies putting any thought into their hiring process?
That process was created by FANG because they can abuse their candidates and still get a lot of applicants (although I think this is less true than it used to be)
But to use that same hazing ritual at a smaller company with the hiring funnel further reduced by a niche language? Really stupid.
