If you spend much time in business, you'll meet one of them. They're not hard to spot. They may have gotten a position by way of nepotism. Or maybe they gave a very impressive interview, but once hired it became painfully clear they didn't have what it took to do the job on a day-to-day basis. They had learned how to speak some of the language of business, but actually getting things done and done well was an entirely different story.
