Ever ace an interview only to find out you didn't get the job? If so, you likely asked yourself a lot of questions about what went wrong: Did I talk about myself too much? Was my handshake too aggressive or too weak? Did I wear the wrong outfit?
The painful truth is that it probably wasn't any of those things. It's more likely that another candidate was simply more likable. That can be a painful lesson to learn, but like it or not, being likable has become a bankable and powerful commodity in today's technology-driven world.
