The way DEI works at my company is simple, for all roles, the expectation is that a diverse slate of candidates are interviewed. This is based only on sex and race. For roles that are so specialized, which many are, that there are not enough with the required skills to do so, you can get an exemption after you have waited enough time for applications to come in. That is it. There is no expectation on hiring, just interviewing.
The worst possible outcome here is that they put in token people who meet some diversity criteria because they really want to hire one other person and don't want to wait or get an exemption, or maybe one of 2. Still those people will have made it through some selection gates and meet minimum requirements. It does not remotely result in poor candidates getting a job. Each hiring manager is accountable for bringing in people who work out, they would not hire based on race or gender.
If my past company, semiconductor sector, did similar, they might actually interview some white people, but instead it was mostly Chinese. Seriously the place went from mostly English conversations near cubicles to mostly Mandarin in the 4 years I worked there. Chinese managers were hiring Chinese graduates from the same groups they got their PhDs from. It certainly helped when working with TSMC, but not with Intel (who mattered then) or Samsung. It's a shame really, the work there was challenging and rewarding, just backbreaking and nonstop.
