Register. You're not going to get anywhere until you register with the career services office
at your college.
Services. There you'll find all sorts of resources and help in preparing for a successful
job search, including help with your cover letter and resume, interviewing help, on-campus recruiting,
and many other services.
On-campus Recruiting. Only a small number of all companies recruit on college campuses,
but you still may find some gems there so make sure you follow the announcements -- and then sign up
for interviews with companies that interest you.
