That's the issue, right? Everyone wants "diversity", but no one wants quotas or hard lines that could discriminate against other groups. I think you need to do your best to root out any biases in your hiring process or people. At Uber's size there is also an evangelism role that can be played to reach out and encourage a more diverse applicant pool to apply for roles. But this report falls flat on how you could possibly measure whether your team is "diverse" or "inclusive" enough and also fails to call out any existing practices, processes or people that would've gotten them there in the first place, opting instead to use those principles as PR tools.
