Most of HR processes are pure ideological bullshit. "Personality tests" that are nothing else but "we search for obedient drones and here is our tarot to help" and "intelligence tests" that are based on some racial science bullshit made to prove the inferiority of Jews that might be useful only if you work in a factory of math patterns.
They are not there to ensure efficient production, after all they don't know shit about the product or internal processes of the teams. They're a caste of priests whose role is ensuring compliance with the feudal-corporate system.
But how else can the corporate bureaucracy hold its grip on people otherwise? The metrics are as necessary as catehism for catholicism.
