I have an interview with the Department of Corrections as a Records Clerk in a few weeks. What can I expect from the interview process?

I've never worked in anything Law Enforcement-related. I've recently graduated with the degree in Administration of Justice and would really want to secure this job. So i want to prepare for the interview as best as I can. Any advice on the interview process for this job (or any relevant positions) would be very helpful. I'm pretty nervous and don't want to blow this opportunity. I'm in California if that plays a role. Thanks in advance!
