There's a new obstacle to landing a job after college: Getting approved by AI

San Francisco (CNN)College career centers used to prepare students for job interviews by helping them learn how to dress appropriately or write a standout cover letter. These days, they're also trying to brace students for a stark new reality: They may be vetted for jobs in part by artificial intelligence. At schools such as Duke University, Purdue University, and the University of North Carolina at Charlotte, career counselors are now working to find out which companies use AI and also speaking candidly with students about what, if anything, they can do to win over the algorithms. This shift in preparations comes as more businesses interested in filling internships and entry-level positions that may see a glut of applicants turn to outside companies such as HireVue to help them quickly conduct vast numbers of video interviews. With HireVue, businesses can pose pre-determined questions -- often recorded by a hiring manager -- that candidates answer on camera through a laptop or smartphone.
