Someone should start an employment scheme where employers and employees both sign up to a broad pool eg "javascript developers" and then employees are assigned to employers arbitrarily but everybody gets hired once before anyone is hired twice and so on. Employers can opt to trade someone back to the pool as can employees after a minimum hire period say a month. Employees that are good enough will stick and the others will get experience and training and will hopefully improve, and will get paid something at least. Employers get immediate employees without having to bother with interviews. If the pool is swamped with unqualified people then the service could implement some minimal qualification process such as a multiple choice test for entry into the employee pool.
No - it would be a standardized subject matter test without any of the personal baggage that sinks most interviews, that an applicant can take online at minimal time and expense.
