Correct if I'm wrong, but I think it's really hard to evaluate it through a zoom talk, unless a candidate comes to a job interview wanting to make a clear point about his/her views. I was expecting more of a presentation about the company's views in that matter.
Thinking on the hiring process as a CI pipeline, I think filtering out people that cannot code is easier and less time consuming, than going through some 1:1 call with their diversity manager.
Wouldn't it make sense to talk with the diversity officer at the very first? I am assuming if you don't tick some diversity checkbox, you'll have much lower change to get hired regardless.
