Don't spend all your time heads down working. Programming is only half the job of being a developer. You have to communicate with your team and other teams. You have design reviews and code reviews. You have to attend meetings. You also need to create and maintain working social relationships with your coworkers so that you have the network of resources when you need it. Ask lots of questions and be eager to learn. Don't be surprised if the company does things in less than ideal ways, there may or may not be good reasons. Also, make friends, eat lunch with your team, have fun at intern events if they have them. My main point is don't spend your time heads down trying to finish your project. You'll be missing on so much if you do.
