Technical skills are similar whether startup or BigCo. I'm talking about everything else. The habits and thinking you'll develop. The way you'll learn to work and interact with coworkers/customers. The things that will motivate you. The way you'll be rewarded or punished. And a bunch of other things. The environment of a well run big company and a well run startup are very different (for good reasons). You don't learn to succeed at one by working at the other.
