It really depends on the size and resources of your company. I used to work for a large French ecommerce company where most of the stack was in Clojure and most of the people we hired were totally new to this language and/or were Clojure fans but were new to the ecommerce world. It didn’t really matter as long as they were motivated because we had the resources to train them and give them time to learn. I left ~1 year ago to join a very early-stage startup where we’re currently 5, and while I would love to hire people that don’t master at least most of the stack we use, I just can’t because we really don’t have the resources to afford to have someone spending time (their time and also other people time) learning everything. This probably an extreme example but it illustrates the point: even if you’d like to hire people in a broader spectrum, you can’t always afford to. [ I hope that at one point we’ll be able to do it :) ]
