Writing a thread on onboarding here, because I don't want to write it in the other place.

Context:
Good engineer onboarding *is* DEI. Teams that have great onboarding, tend to be more diverse and inclusive. Teams that have poor onboarding, tend to be more homogeneous and less diverse.

That's because poor onboarding makes life harder for junior employees and remote employees. Underrepresented groups benefit disproportionately from remote work options. Junior employees are a more diverse group.
