The hiring manager was emphatic, "If they don't send a Thank You note after the interview, they're not going to be invited back for a second interview." My conversation that day with another hiring manager in the same organization went quite differently. He didn't give a fig about Thank You notes. His hot button was intensive research, "If they haven't prepared for the interview by looking beyond our website, they are not who I am looking for." The second manager expected each candidate to have spent about three hours on research, and he expected that they would walk in with at least 15 thought provoking questions that demonstrated an understanding of both the industry and the organization.
