Unless you were an accounting, math or economics major most people find that Career Offices don’t have enough bandwidth to support their search for true meaning. Really, how much tolerance would you have for your college senior self?
Now is the time they can really help you: by giving you a username and password to your alumni database. These provide a great source of networking. Most have great flexibility in how you can search including by city, by field, by organization and by function.
Find the people who are doing what interests you and reach out. Most people enjoy hearing from someone with ties to their college years and everyone (1) loves talking about themselves and, (2) has been where you are.
Send an email. Ask if you can schedule a short call. Use your elevator pitch. Ask how they got their start. You never know.
