I’m not in a position to make hiring decisions but I wanted to amplify this for anyone out there who is. Even if you’re not, it makes great points about how non-diverse workplaces (or any space, really) just happen unless you work really, really consciously against it:

It’s so easy to like people who affirm either our own existence (we hire people who look like us) or affirm the decisions we’ve made in the past (we hire people who look like the people who already work for us)

The hiring advice itself is specific and actionable, so if this is for you, check it out: You Can Hire Better by Boss Barista.
