This is interesting data.<p>I liked what Joel Spolsky said a long time ago. Basically that companies should want two types of engineers. 1. You want a few who are experts in the company&#x27;s tech stack. 2. The bar for everyone else is just that they&#x27;re smart and they get things done.<p>I guess the core problem is that we don&#x27;t have a good objective measure of the latter. (Maybe an IQ test for smarts, if that wasn&#x27;t political incorrect, but I don&#x27;t know how you&#x27;d show definitively that you &quot;get things done&quot; in an interview.)
