Last June, in an interview with Adam Bryant of The Times, Laszlo Bock, the senior vice president of people operations for Google — i.e., the guy in charge of hiring for one of the world’s most successful companies — noted that Google had determined that “G.P.A.’s are worthless as a criteria for hiring, and test scores are worthless. ... We found that they don’t predict anything.” He also noted that the “proportion of people without any college education at Google has increased over time” — now as high as 14 percent on some teams. At a time when many people are asking, “How’s my kid gonna get a job?” I thought it would be useful to visit Google and hear how Bock would answer.
