Networking involves establishing goals, analyzing help needs, and developing interpersonal skills to build and cultivate connections. It is important for finding jobs as referrals generate more results than cold calls. The key is to see networking as a two-way relationship where you are also willing to help your contacts. Using your network effectively can reach millions of people through multiple levels of separation. Tips include asserting yourself positively, asking good questions, being a listener, and keeping your network active over time.
