Vocational Biographies, business directories, the yellow pages, Internet newsgroups, and Internet home pages are useful sources for contact information. Contact each person on your list. Direct your inquiries to people knowledgeable about hiring practices. Say you are seeking advice and information , and that you will be brief. Explain you are seeking career information, not employment.
Most people are willing to interact for a short time.
It may be necessary, however, to check back. Try to get a name, then ask the person when would be a good time for you to check back. Write down the key comments. Your survey results will be more reliable if you contact several people. Contact between six to ten people to obtain a valid sample.
