Tell Them a Little About Yourself
While the primary focus of the interview should be to gain insight into a particular organization or career, share some of your background with the contact in order to strengthen your professional relationship. Remember that you are there to learn more about them, not just to tell them about yourself. Highlight relevant experiences and anything you may have in common.
Ask for Referrals
This is a good opportunity to learn the names of others that may be able to help you gain additional insight into the field. Ask your contact if they might introduce you, refer you to, or provide contact information for someone else to contact within the profession. Make sure to collect business cards from people you meet and offer yours as well (as a student, it is a good idea to create some business cards for this purpose). At the end of the meeting, offer your resume for future reference. Tell your contact that they are welcome to share your resume if they know someone who might be interested.
