Mentioning that a poc is successful only because of their colour is harsh. Maybe they bring value and have qualities that other candidates did not have. DEI only widens the pipeline, no private company lowers their standards.
The company i work for does not have any quota and neither does meta. There is no lowering of standards to hire somebody, just more effort to get wider application pool and outreach programs to schools.
Also DEI is not just based on colour or ethnicity. There are other groups like mothers, neuro divergent people etc.
