Amazon isn't the only tech giant actively shaping the programs that will train its future employees and customers. Google, Facebook and Apple also are collaborating with colleges as more companies face a shortage of skilled workers who can navigate an ever-evolving tech landscape. In some cases, the companies are covering the costs of the programs for students; in most, they earn no revenue. College officials say the partnerships help ensure their students graduate with the skills and knowledge employers want, as well as get priority for internships and jobs. Tech leaders say colleges — and two-year colleges, in particular — provide access to a diverse pool of candidates for jobs that don't require a bachelor's degree. They also have important connections to K-12 schools and four-year colleges.
