It was okay..
Boring workplace. Night shifts are a pain, typically just respond to false alarms and patrolling.
I learned the procedures of medical emergency, fire panel, etc
Workplace culture was okay, lots of Asians, mainly Cantonese and Mandarin workers since it's an living area for old Asian people.
Hardest part about the job was the terrible shifts, it was affecting my health.
Most enjoyable part of the job would be being able to have time to do everything without having to be under a lot of stress unless emergencies happen.
Long painful night to morning shifts, low pay
