Government job interview

Hi all, I attended an interview at a government organization in the last week of November, and the interview went really well. However, I haven't received any communication from them since then. I have the contact number of the person who called me for the interview, and I sent them an email thanking them for the opportunity and asking for updates. Unfortunately, I haven't received a response yet. The interviewers seemed really pleased, and I was confident that I did well. Even if I wasn’t selected, I expected to receive at least a notification informing me of the outcome. Is it normal for government organizations to take time to provide updates (whether selected or rejected)?
