Start with professional organizations and social groups. Attend events and volunteer for committees.
Most student organizations have relationships with companies and hold company presentations or networking sessions.
Often times your parents may also know someone at the company you’re interested in working for, and if that is the case it’s also acceptable that they pass along your information to that friend/acquaintance as well.
Networking is simply connecting with those who share a common interest or goal. If you surround yourself with people who share your interests, you will find that connections are made much easier.
[M]any campus groups have strong alumni bases that share opportunities within their industry with the students in the organizations that they were involved with in school.
Another great way to network with both working professionals and young professionals is on LinkedIn. There are many different groups; whether it is a group about your interests or actual companies. You can meet people that are also looking for networking opportunities and you can also receive networking advice on how to advance your new career.
Try to search for those groups that are applicable to what you want to do and request to join them. Once in the group, you have the ability to send messages to the other group members, which could be the beginning of your actual networking efforts.
Target the companies you are interested in working for and connect with current employees of that company.
A key component to networking is follow up, however I suggest limiting the number of times you follow up with someone.
I would recommend setting up a meeting with Career Services at your school to find out more about the opportunities that are available to you.
