I work for a state government agency, and we tell people during the interview process that hiring takes a while. Experience has taught us that it generally takes 6-8 weeks for our HR department to process everything and notify applicants, and we let applicants know. HR is understaffed and they have a lot to take care of, so there are legitimate reasons for this.
If this agency is anything like mine, the issue is already out of the hands of the people actually offering the job and in the hands of people who have to perform the mundane parts of the hiring process. I wouldn't be surprised if your interviewer cannot answer your question.
