LoL. First job, and good enough to do it all. Those first few months are going to be tough.
Nothing personal, but "the big fish" will show you how little you know. I've learned WAY more at work than I ever learned at school and still am just scratching the surface. I probably learn 10 new things every day - after almost 3 years.
Humility makes the old hats want to teach you more, just a friendly piece of advice.
Knock it out! Good luck.
