Discuss your career plans with your classmates. Remember some of your classmates may not be in the position to help you right now, but they may be of assistance next year or even ten years from now. These graduates have volunteered to serve as career advisors and are willing to participate in informational interviews. Get to know your faculty members outside the classroom. Many have valuable experience and contacts in your field of interest.
Some professors are consultants to industry.
If you're sincerely interested in a professor's research, volunteer to assist him or her. For example, help plan an event or arrange for speakers. You'll not only gain valuable skills, but you will also make many professional contacts. Make sure your internship and other work experience reflect your career interests. Get to know your supervisors and colleagues.
