So if you want to get good, you need to work with people that are better than you, who have already learned from their mistakes so you don't have to. Find the strongest shop that will hire you. It will not be the best shop. It probably won't be an elite startup. But more mature companies can afford to pay for your learning curve. You also will probably make more money, enough to pay off your student debt and save up to bootstrap when you're more experienced.
