Everybody needs work experience, even with a degree, to be able to find a good job. It is also a good way to find out if the career field you have chosen is where you want to be. Here is a video to give basic information on how to find internships, and what to do when you get one:
A good resource to start with is your school because they will have more information and ideas than you will. You can go to the Student Employmeent and Cooperative Education Services to get some coaching, and possibly a few ideas for where to look for internships. You can also use SLCC's Career Coach to help find a good career based off of several criteria.
Be prepared to find your internship several months before you're ready to start. There will be a lot of competition for the good internships, so if summer is the time you want to go, be prepared to start looking in December and January to meet the deadlines. The best time to do an internship is during the summer when you're not taking classes. This way you can devote yourself to the internship. But that doesn't mean summer is the only time you can be an intern. There are both paid and unpaid internships, and it is possible to find them if you know where to look. If you haven't already, sign up with www.fastweb.com to find scholarships. It can help you find scholarships at your school, as well as all over the country. It also lists internships and fellowships that you can apply for. A couple other websites to try are internships.com, internshipprograms.com, Monster College, and internqueen.com. If there are specific companies you want to work for, check their website or contact them to see if they have internships. Companies do not always broadcast their internships, or make it easy to find, so don't get discouraged if you can't find the information right away. These are just a few of the sources you can use.
Just remember that not all internships pay, or pay well. Make sure that you can afford to take the internship. If you want to, generally schools will let you earn credits for your internship, which means you will have to pay tuition. If you want to get credit some schools require that it be an unpaid internship for that to happen, so double check with the school if that is the route you want to go.
