It’s usually more than just “not only hiring old white dudes” but a conscious effort to make the place more representative of society by intentionally hiring people of diverse gender/ethnicity/handicap instead, sometimes leading to processes being closed to people who aren’t part of certain groups, which might in theory go against some laws depending on where you live, but the same thing can be achieved by just wasting time filtering out white men’s CV or just not calling them back after interviews, so I personally don’t mind just being excluded and giving others a chance, if they don’t have non white dude applicants then I’ll get called and otherwise I’ve got plenty of doors open to me, more than most in fact and that’s not ok.
