The purpose of this meeting is really to help me learn more about the field. At the end of this section is a list of questions you can use as a guide to design your own interview questions. Your goal is to learn about the field, get advice and get information. Ask questions that are pertinent to you and help you become better informed. When you introduce yourself, you can chat briefly about who you are so that the interviewee can get to know you, but remember the purpose of the meeting is the interview.
People often enjoy talking about themselves, their work and giving advice.
Be prepared to spend more time than the 15 or 20 minutes. But be sensitive and don't overstay your welcome. This is good business etiquette and is a useful habit to cultivate. The second step, once you know that you are really interested in this kind of work, is to call your interviewees back. Thank them again for all their help and let them know that because of the information they gave you, you have decided on this field for your career.
