Pros
You will come to master DI workflow. There are some great people on the assist / operations teams.
Cons
Interactions with (most) colorists are generally without acknowledgement or reciprocity. That alone would be tolerable; however, you're also grossly underpaid. With little-to-no opportunities to move up. There are no lunch breaks - food is brought to you as you continue to work. You're expected to work a ton of overtime and weekends. The culture is not one of collaboration, reward and shared enterprise - but of blame, frustration, and needless urgency. Attempts to improve communication and working conditions are stymied as everyone is too busy and too afraid of the mercurial boss to rock the boat. In short, it's an unhappy place to work if you're not one of the colorists.
