Additionally, the present day ambiguity of hiring standard can stand to improve greatly. The layer of unqualified recruiters, assessment test, hiring staff and even HR departments can be replaced or upgraded to a more universally accepted standard which allows it to be easily administered by a broader demographic. I believe that it is a lack of this sort of standard that contributes to current hiring issues like disproportionate race or gender representation and mismatching employees with open positions.
In my own personal experience I cannot count how many times I have been sourced by a recruiter who has no clue what the technical expectation is for the position they are working on. Many recruiters that have contacted me are clearly unqualified to assess technical competency for the positions they are trying to fill. They literally read the technical keywords from the supplied job description.
