The art of networking is the process of getting out and meeting people both in a formal and informal manner. Use every opportunity you have to meet people face-to-face. This will allow you to create contacts that may be hiring in the future or allow them to refer you to other potential employers.
You should account for a considerable amount of time to allow for this process. Spending 30-40 percent of an actual job search on the process of networking is a good guideline. This will include personal meetings, attending functions, phone calls, e-mails and follow ups. Networking will help you find more job positions that you may not hear about through normal channels. The larger the network you create the greater the chances of you finding available positions.
