In December 2012 the sociologist Lauren Rivera published a study of hiring at elite professional service firms in the American Sociological Review. It drew on 120 interviews with employers. “Employers sought candidates who were not only competent but also culturally similar to themselves in terms of leisure pursuits, experiences, and self-presentation styles.”
Such concerns “often outweighed concerns about absolute productivity.” Evaluators described an “airport test”: whether they would want to be stuck in an airport with the candidate.
