Identify the Information You Want - Deciding which position, company or industry you want to learn about will depend on what you want to do with your life and career. You should have a sense of what is important to you and what you want.
Make the Appointment-Set up a 15- to 30-minute interview with the person identified, regarding their specialty. Most people will be more than happy to help you. Don't get discouraged if you find some people are just too busy to give you an appointment.
Plan an Agenda for the Session- This is your meeting. Don't assume the person will give you the information you need unless you ask the right questions. Select questions that will give you the most information. Be efficient, and do not overstay your welcome.
Conduct Yourself as a Professional- Dress and act the role of the position you are seeking. Know as much as possible about the company before the interview so you can ask informed questions.
Send Thank You Letters - Thank the person at the conclusion of the interview, but also send a note/email stating your gratitude for the time given.
