Tim Smedley focuses on the recruitment strategy of Xerox. CVs are no loger decisive. Big Data are: “For Xerox this means putting prospective candidates for the company’s 55,000 call-centre positions through a screening test that covers a wide range of questions. Evolv then lays separate data it has mined on what causes employees to leave their call-centre jobs over the candidates’ responses to predict which of them will stick around and which will further exacerbate the already high churn rate call centres tend to suffer. The results are surprising. Some are quirky: employees who are members of one or two social networks were found to stay in their job for longer than those who belonged to four or more social networks … Some findings, however, were much more fundamental: prior work experience in a similar role was not found to be a predictor of success.”
