This piece from the New York Times touches on a subject that I’m passionate about - the challenges of hiring good people. Deep into it, it mentions that:
”…the most proven method, Dr. Lewin said, is a referral from someone already working there. Current employees know the culture, he said, and have their reputations and their work environment on the line.”
The big data thing is a cool, tech solution, but really it’s referrals that matter.
