Connecticut College senior Paul Dryden has known for years that he’d have lots of competition for an entry-level promotions job in New York’s music industry. So in a bid to get an edge last summer, he invented a job for himself. The job, as an intern in Universal Music’s Buenos Aires office, had never existed before Dryden proposed it. Yet because he was willing to work without pay, he got his foot in the door and was soon translating interviews with American rock stars for his boss, who didn’t speak English.
