There is nothing wrong with outsourcing your job, but if you are a hiring manager, you are supposed to be good at recognizing, placing, motivating and rewarding talent. Humans are icky and complicated and I am skeptical of any and all means of evaluating them that does not involve another human. If you are hiring for a job, and you think it's possible to objectively assess someone,s eligibility against some requirement, then you maybe should be looking into robots and automation for that role.
