This is what peolle that want a programmers guild or union want. Put up barriers to new entrants so they can protect their prestige and positions.

I do hope sites like Hacker Rank set a model for finding workers on pure talent rather than degrees or anything else.

The article specifically states that an arbitrary measurement of "professional" fitness is the problem. How would a ranking system be any different than a credential system?

A more effective solution at finding the right candidates is an educational system available to all.

Yes, will be good. Also important is the free movement of talent to where it is needed.

>arbitrary

Not all ranking is arbitrary. A lot of it is targetted for the skillset a job needs. What I find arbitrary is quotas. I see this in medicine and actuarial science. Where instead of basic competency, they take the top x %.
