Based on your use of the words jobs, offers, interviews, etc it sounds like you're assuming that being on a Rust team is a paid job. This is not the case. Mozilla indeed employs a lot of the people on the teams, but I have my own company, for example. I do not get paid because of my membership on the teams. And there are people who work on Rust at Mozilla who are not on the teams; these are a disjoint set.
That's indeed news to me. The press releases had me assuming otherwise. I appreciate you and Steve telling me so I can get better accuracy in future conversations. What's the split of paid people to volunteers on the page I linked? Especially in compiler, language, library, and community teams?
Out of almost 60 distinct people, roughly 15 are employed by Mozilla by my quick count. It gets a bit fuzzy because some people have done things like been an intern, did a few months on contract, or something else, but that's the current count.
Well, it's cool you have so many volunteers. Also, the lack of diversity isn't as bad as it initially appeared if we're including volunteers. There could be bias but donating time/money for good things must be a good thing by default. :) The critiques would only still apply on hiring level if the 15 were mostly white males in circumstances where more minorities could've been hired. Any suggestions or brainstorming would also still apply since they address the supply or acceptance side rather than just Rust specifically. It's just one instance where the techniques can benefit.
