Finally, learn as much as you can about the employer and the position so that you can ask good questions. If you can go to your campus career center for information and advice, that kind of personal attention will be very helpful to you as well. I'm approaching my senior year and need to begin searching for a job. Find out when all career fairs have been scheduled. Also, be sure to find out when companies recruiting for your major will be on campus conducting on-campus interviews.
Different companies have different campus recruiting methods.
Some will come on campus early for presentations, etc. Make sure you attend these events, as they will make you more informed and will give you more face time with the company representatives. Research companies that you are most interested in and begin engaging with their campus recruiters. It's never too early to express an interest.
