When it comes to networking,
LinkedIn is an indispensable resource. Schools typically maintain a presence on LinkedIn, and there are numerous official LinkedIn groups geared toward smaller niches within the larger community. You'll see LinkedIn groups devoted to alumni, veterans, colleges, departments, degree programs, and extracurricular interests. You're certain to find one or two groups that align with your personal interests.
Students don't need to wait until after graduation to start networking. If you start participating in pertinent LinkedIn groups while you're still a student, you'll already have built a solid network by the time you graduate.
Even after graduation, you'll probably want to stay connected to your school's community. They'll find out about benefits like alumni events and have access to a network of other students, graduates, faculty, and staff all over the country. Leverage your school's connection to build a formidable, professional network. You never know when a fellow alumnus or a former professor might be able to help you out in your life or career. They may have leads on the perfect job for you, or maybe just some good advice.
