Examples are going to be hard to come by. No company is going to publicly admit that they used to be limiting their hiring pipeline in such a way. Admittedly, this also means that I'm speculating that the number of companies are "vast". Surely many have quietly made the change.

Sample size of one, I worked in the past for a company whose entire staff was white men, 100%. Except for a single role: the receptionist at the front desk. There is no reasonable biological explanation for this extreme distribution.
