Pros
-the people you work with will be the most dedicated artists ever -for the most part, the artists around you will push themselves and you to always do better work, and more efficiently -you get to do work from other big name studios (blue sky, dreamworks, WB, etc) -you become so efficient at what you do, that you will not be intimidated by going to a bigger studio -generally you can make changes for the better in regards to your department, depending on your supervisor. -most supervisors are helpful and know what they are doing. you can learn and grow from them.
Cons
-company politics, rumors. no matter how much they try, rumors and politics circulate down to the employees. depending on the rumor or info, it may cause you to have a bad day. -upper management won't care about you. they have no concept of employee appreciation or reinvesting. -benefits are very minimal. no perks, no bonuses, no over time pay. -jobs seem to be underbid just to get them in, which causes artists to always get overworked with no real benefit other than a 'job well done' -they seemingly do not care about long time employees quitting in mass quantities -it is the only large animation studio in the area -they dangle a carrot to keep your hopes up for future feature work, but never commit to it. -jobs seem to be understaffed a lot, causing you to work extra hours and make up their mistakes.
