HR is the bane of progress. HR is there for only one purpose, to keep the company from receiving lawsuits. It does not matter if the person they hire is competent, convivial, corrigible, or even capable of just showing up. They only pay attention to whether it follows their departments' regulated practices.

In hiring, HR is called upon to select someone, from a pool of sometimes thousands of candidates, based first on their resume/CV, a document broadly expected to be full of lies and exaggeration, (which increases likelihood of hiring someone dishonest) and which can have no visible indications of what the applicant can actually do, then based on an/a series of interviews, a practice which only tests the candidate's ability to bullshit/be charming for short formalized conversations. (increasing likelihood of selecting for neurotypicality or unreasoning confidence) No HR person knows enough about essentially anything else anyone does to actually be able to tell the difference between a beam collimator and a retroencabulator, and staffing agencies make it even less likely because they are even further from the work.
