Strudelkugel writes in with a story about how big data is being used to recruit workers. "When the e-mail came out of the blue last summer, offering a shot as a programmer at a San Francisco start-up, Jade Dominguez, 26, was living off credit card debt in a rental in South Pasadena, Calif., while he taught himself programming. He had been an average student in high school and hadn't bothered with college, but someone, somewhere out there in the cloud, thought that he might be brilliant, or at least a diamond in the rough. 'The traditional markers people use for hiring can be wrong, profoundly wrong,' says Vivienne Ming, the chief scientist at Gild since late last year. That someone was Luca Bonmassar. He had discovered Mr. Dominguez by using a technology that raises important questions about how people are recruited and hired, and whether great talent is being overlooked along the way."
