A bit of a trivia. Recently I was reading one of Erik Dietrich books and learned that modern job interview was invented by Tomas Edison. Edison used to go through a lot of candidates and at some point was extremely frustrated that the college graduates would lack knowledge that he found essential in someone who would want to work for him. As a result he came up with a “test” that had series of questions of general knowledge. Some of these questions related directly to the position that the applicant was seeking, while others were related to topics such as geography, history or literature. It’s unlikely that more than about 7% of all applicants could pass Edison’s test. Apparently an industry wanted to emulate Edison and began using similar questionnaires of their own. More info here.
