Hearst's Joanna Coles: How a dogged reporter became Editor-in-Chief of Cosmo and Snap's board member

Joanna Coles is the Chief Content Officer at Hearst, and was the Editor-in-Chief of Cosmo and Marie Claire before that. She's also the executive producer of a hit show on Freeform and a member of Snap's board. Coles told Business Insider's US Editor-in-Chief Alyson Shontell how she had to throw someone out of a cab to get a job, her negotiation strategy, and the power of a good network on this episode of "Success!
