Super easy and relaxed atmosphere
I was in a team for a temporary project, and it was one of the best experiences of my life. The job was simple, and because of its simplicity, we were left to our own devices and only called in for weekly meetings to discuss any specific details or incidents that needed attention.
Food and snacks were always available, and we were able to come in and out as we pleased, as long as we where there for 8 hours and met our quota.
This relaxed atmosphere encouraged me to work more and it was definitely very easy to work there.
