There’s been a lot of chatter lately about the potential for artificial intelligence (A.I.) and machine learning to reshape business. Certainly it could reshape hiring, by casting a machine eye over the mountains of resumes sent to fill open positions. But when it comes to hiring the right tech pros for various positions, A.I. can only go so far. In the end, it’s a hiring manager who interviews job prospects—raising the risk that a human could screw up. The solution may not involve more technology, but in making sure HR interacts with other parts of the business, including marketing and tech.
