Remember that you are a student, you are temporary, and whatever the assignment, it will be considered important to the office. At the same time, most firms will tell you that the internship is what is made of it, and making something of it will be your job. If you are in the circumstance, where you are not doing substantive work, make it an opportunity to network. Get to know the team in the office, what they do, and how they do it. It is up to you what you learn from the experience.
Internships vary on compensation.
Some will pay substantially while others may not pay you by a monetary sum. The question you will have to ask yourself, is whether the internship experience is worth the effort. The payoff may not be reflected in the paycheck , but it will be relected in the valuable experience gained by working in a professional environment. As you begin your internship search, you need to determine how much money, if any, you will need to make. Companies will offer to reimburse the intern for transportation and other incidental expenses.
