As I waited in the lobby at Capital One in Seattle, a group of well-dressed, inquisitive 13-year-olds arrived - joking, laughing, all while keeping their voices down in order to mind their manners. I eavesdropped a bit to get a sense for what they were feeling, and it was a mixture of excitement and nervousness. They were here at Capital One to learn about what it takes to succeed in a career in the fast-growing world of tech.
