Start-ups like Gild, Entelo, Textio, Doxa and GapJumpers try to automate hiring and recruiting. Claire Cain Miller writes: “So where do humans fit if recruiting and hiring become automated? Data is just one tool for recruiters to use, people who study hiring say. Human expertise is still necessary. And data is creating a need for new roles, like diversity consultants who analyze where the data shows a company is lacking and figure out how to fix it. People will also need to make sure the algorithms aren’t just codifying deep-seated biases or, by surfacing applicants who have certain attributes, making workplaces just as homogeneous as they were before.”
