Apply for jobs that fit your educational background - financial managers have no incentive to hire a nursing or engineering student over a business major, regardless of how good your GPA is. Make sure to check your facebook account for information you don't want your boss to see - this is definitely checked by the departments to weed out people. Relax and be pleasant, they are mostly looking to see if you're a good fit with the department. Don't try to bluff on things you don't know.
