Finding a job used to be simple. You’d show up at an office and ask for an application. A friend would mention a job in their department. Or you’d see an ad in a newspaper and send in your cover letter. Maybe you’d call the company a week later to check in, but the basic approach was easy. And once you got a job, you would stay—often for decades. Now . . . well, it’s complicated. If you want to have a shot at a good job, you need to have a robust profile on LinkdIn. And an enticing personal brand. Or something like that—contemporary how-to books tend to offer contradictory advice. But they agree on one thing: in today’s economy, you can’t just be an employee looking to get hired—you have to market yourself as a business, one that can help another business achieve its goals.
