There is, based on what I have seen, a decoupling between tech screens and the ability to perform in a job. I'm a big fan of a takehome assessment if you're really worried about someone's skill, but these days when I am screening teammates for my own team I focus my questions on problem solving, troubleshooting, and analysis. Between assessing those skills and a candidates basic interpersonal communication I have had incredible results and have a wonderful team as a result.
