There's no such thing as the world's best resume. Job vacancies might appear generic, but behind them is a hiring manager who also tends to be unique. In today's job market, you'll probably be continuously re-evaluating where you are, where you want to go, and the best way to get there.
Companies also reinvent themselves, and their needs change too.
This swirling around of people and positions creates ongoing opportunities. Your ability to stay in the loop will make the difference between being picked and getting left on the vine. The world's best job may never appear in the newspaper. That's because people prefer to work with people they know. As humans, we fear what we don't know.
