Last spring, Arturo Cano, a nineteen-year-old communications student, sent out his résumé for summer internships. "I mean, where didn't I apply?" Cano, a Mexican immigrant living in California, said recently. "Bloom, WaPo, a lot of media publishers all over America; Buzzfeed—twice." He was either ignored or rejected by all of them. Then he came across a notice on a Reddit thread for a "producer internship" at a startup.
