A bit unclear. Is this for a public civil servant, or? In either case your resume must be good, you must be able to articulate the claims made in the resume. They will ask you key questions related to the work and likely personnel engagement. They will also have a question or two that highlight who you are as a person.

In any case look and articulate the part.

I was an Army Civilian program manager. I did many interviews because of job openings in my division and the Directorate I was in. Here's some tips.
-Know your resume. Be prepared to answer questions about education and experience shown in your resume.
-Be prepared to answer any possible shortfalls in your experience or education when compared to the job requirements in the announcement. For example, if you have a Bachelors Degree with 4 years of experience and the announcement wants 6 years of experience. Be prepared to say why a degree should be substituted for two years of experience. (The announcement may allow it.)
-Every applicant is asked exactly the same questions in the same way as closely as possible. Don't act surprised or offended if you are asked a question that is clearly answered in your resume.
-You may be interviewed by a panel of three or more employees. They may talk among themselves during the interview. Don't worry about it. Also, they may go "off script" and ask follow-up questions to the standardized questions.
-Be prepared to ask at least one constructive question about the job, location, working conditions.
-If the job is supervisory in nature, be prepared to respond to some "what if?" or situational questions related to managing people and things.
-In the IT world, certifications can be very important. If you have listed certifications in your resume or application, be prepared to explain what they are and how they are related to the job requirements.
-If the job is highly technical, be prepared to answer questions related to the knowledge and skills needed to do the job. At least one of the interviewers is probably a technical expert.
-The person or people you are talking to may or may not be the hiring authority. Normally they can't make a job offer during the interview. They should tell you when they can get back to you with an answer.
-Expect to have a phone or electronic communication interview. Have the technology you need ready to go. Have a silent and private place to do your part. Understand how the mute button works!

Good luck!
