Pros
The only pros I can see are the big name projects but even that doesn't do anything for you if the majority of all the shots stay in LA and Melbourne only gets the leftovers. Of what's left the hero shots will go to the people that have their head stuck as far possible up the supervisors behind.
Cons
Like others have said the company culture is the worst part of the whole experience. Loud and obnoxious behaviour is encouraged and it's looked down upon if you don't partake in the ridiculous "fun" activities. There is constantly loud music playing in the entire office and people yelling over it without any kind of awareness for the rest of the artists trying to work. On top of that all the supervisors have not a lot of experience and most of them never worked for any other big studios and lack the relevant social skills to actually deal with artists and motivate them to do great work. Artists are encouraged to work against each other and be competetive by giving individual people a shout out in front of everybody and not putting a focus on actual team work. Communication between artists is almost non existent. The pipeline is almost non existent and a lot of stuff is just being done on the fly. So a lot of days you spend more time trying to fix stuff than actually working on your shots.
