In fact, I would argue that you learn the wrong things working for a big company, and that it’s actually not good experience. A good experience is when you really make something happen in the world. Big companies teach you how to work through layers of bureaucracy and how to solve problems in very risk-averse ways “” in short, how to make something happen in their organization. A big company is not the safe career choice. It’s the risky choice. It risks your mind and your life.
This goes hand in hand with another misconception that big company jobs are more secure than startup jobs. In my experience the chances of a startup running out of money and a big company needing layoffs are roughly the same.
