Mini-job as a job seeker? Mini-job/temporary work after training while looking for a full-time job?

Tips/advice?

Hello everyone,

I finished my apprenticeship last week and unfortunately haven't had any success finding a new job yet. However, I have interviews scheduled in the coming weeks.
(I started applying in December, but unfortunately I was always rejected because they needed someone immediately with a completed apprenticeship)

I still live at home and only registered as a job seeker because I had problems with the system and hadn't yet made an appointment with the agency.

Now to the topic.

Am I allowed to work a mini-job? I don't receive unemployment benefits and haven't registered yet.

I plan to continue doing the mini-job alongside my main job, which I will hopefully have in a few weeks.
