You can contact a job hunter and if they know you are looking for you first job. They will usually bring you into their office and provide you with some helpful interviewing dos and don'ts.

You can also get mock interview on campus at one of their career center. Some schools will have mock interview for different schools. For example, business schools will have their own schedule for performing mock interviews, etc. Practice makes perfect. It wouldn't hurt to try it out first.
