I've had incredible success in gauging candidates skill-level using TripleByte Screen. Everyone I've hired has taken the test. It's not a pass/fail response but it is fairly indicative of someone who has worked full-time in their tested language/skill.

If the tests go away, I don't know what I will do to help gauge candidate skill without traditional and wasteful live / take-home / repo-based tests.

As an evaluation tool, TripleByte was great. As a user of Magnet (the recruitment marketplace), it was not so great. We signed up during the hiring frenzy of 2020 and the good candidates we tried to get were all getting offers from much more established brands. We didn't see any success there, but TripleByte Screen is an excellent product I hope remains available.
