Most well-credentialed people would.
Most under-credentialed people are thankful for skills-based testing because it levels the playing field.
I'd like a way to prove my skills once, rather than with every interview I have. I bet CS grads would as well. The interview process is just so... tedious. And in a field where you get significantly more money by changing jobs, that's a problem.
It's a market inefficiency imo - people get stuck in jobs where they aren't paid enough for at least some amount of time. People can't hire new employees quickly because the process takes forever. I've been on both sides of the interview process many times and it's extremely inefficient on both sides. We're developers... this should be streamlined and automated.
