"Certifications" doesn't get there - too easy to just game a multiple choice test. I would like to see a formal education + testing requirement (ala Doctors, just not 10 years!) Essentially, a barrier of entry for serious programmers. That would ultimately come with a high minimum salary without having to get hired at faang.
College accreditation doesn't cut it either. I work w programmers with an MS in CS. Programmers are kinda impressed. Managers could care less.
The insanely high demand for labor and (always present) priority to reduce labor costs however encourages the entry of boot-camp you're hired on the low end of experience/competence.
