Pros
Colleagues come from different backgrounds so that is nice.
Cons
In my case, information given during the interview was not correct which caused me to work in an additional language for free for the first months. Communication with my supervisors regarding new tasks was near non-existent. There is a constant shift of responsibilities as mentioned by another poster. You will get to hear supervisors openly speaking about agents' performance (and other supervisors) in front of everyone. Despite being quite a colorful place with people from everywhere, there is a culture among some supervisors to be making discriminatory jokes based on ones nationality. I caught my manager red-handed sending messages about me to another agent. edit: today was my last day and when trying to return my items my supervisors kind of forgot that a document needs to be signed to confirm me handing over the things. They reserved an amount from my salary to ensure proper handover of equipment but did not make it possible for me to return in on my last day.
