One of the recurring themes in any entry level job search is the lack of experience factor. "Where do I get experience if no one is willing to hire me?" The answer is simple: Get an internship!
Students planning to enter the permanent work force should complement their academic preparation with a range of other experiences, such as study abroad, community service, undergraduate research experiences, participation in sports and other student organizations, membership in pre-professional organizations, and internships.
An internship offers you the chance to learn by doing in a setting where you are supervised by a work-place professional, and have the opportunity to achieve your own learning goals, without the responsibilities of being a permanent employee.
An internship also offers you the opportunity to work with someone who can become a mentor for you - not only in the internship, but throughout your career.
