Here’s one thing Slack did:

 In 2015, Slack worked with Textio, a company that analyzes job descriptions to ensure they appeal to the widest possible audience. (Slack’s job descriptions feature phrases like “care deeply” and “lasting relationships,” which statistically draw more applications from women. Microsoft’s, by contrast, feature words like “insatiably” and “competing.” Amazon’s keywords: “maniacal” and “wickedly.”)
