Set goals for the meeting. Relieve any tension by stressing that you did not request the meeting to ask for a job. Explain that you are making a change and you are here to explore ideas about your industry and your next career step.
Many people hesitate to contact others for fear of imposing or asking for help.
The mistakes most candidates make is not preparing sufficiently for each meeting. Concisely lay out what you want to discuss. Be brief and stick to the point. Summarise your background and experience - What you say, should be similar to the summary statement on your resume. Make known your career goals and objectives.
