Advice for Job-hunters:
"Develop a contact network. Once you have targeted a career-path or specific position, you should acquaint yourself with professionals in that field or organisation. These professionals can offer you an industry insider’s view and can constitute your contact network, which can open doors. Your business network can also consist of people like family members, friends, professors, and those from electronic discussion groups."
