You develop friendships and create alliances with organizations that will benefit you now and throughout your career. Most people enjoy helping others, especially students. They remember what it was like to be in your position. Networking is the most successful of non-traditional methods. I find that one of the easiest ways to network is through professional organizations.
Professional organizations are usually one of the most direct sources for job leads.
Often the organization's members have job openings or know about those that will be available in the future. Contact your department head or faculty advisor for the organizations that are related to your major. Most have student memberships that are relatively inexpensive. Making contacts on your own may be more difficult but can be just as successful. Anyone is a potential contact and may be able to open doors for you.
