Hi,
to avoid quarantine for self-inflicted unemployment you must have stopped working before your graduation date. So if the graduation date is the day for your thesis defense, then you must have stopped working at latest the day before.
It dosen’t matter if you get paid salary later (for your work performed up to your graduation date).
It is not relevant whether the job is only for students or not.
SU will stop automatically at graduation, and is not relevant i relation to unemployment benefits.
Let me know if you have some comments.
Best regards,
