Job boards aren't the problem. The problems begin and end within the boundaries of companies. ATS, recruiter, hiring manager, 6 30-60 minute interviews. Those things are the problem.
If I had the money I could go hire a half dozen solid software engineers and at least 2 solid DevOps/SRE types today. I'm betting people in other fields could do the same.
And yet, good people remain unemployed and scared.
