It's never to early or too late in your college career to start gaining experience in your field. Volunteering, Internships, Research, Part-time Jobs, etc. are all important to your career path--START LOOKING NOW!
Just like when you write a resume, there is no one “right” way to search for an internship or job. A variety of strategies should be used to find your next job. Keep in mind that searching for a job, IS a job! Create a routine workable schedule, and then stick to it.
