Avantages
They use legal (legit) software, though you have to prove the need for any non standard software over and over again while waiting for it to be order if it ever is. Same goes for hardware. Lots of really good artist all being held down to the same poor standards.
Inconvénients
MANAGEMENT! MANAGEMENT! MANAGEMENT! And poor working conditions i.e. cramped quarters, poor temperature control and moderation, extreme difficulty to get needed software and/or hardware to make job performance increase Terrible job planning, structure, and oversight. Expect to be given little to no lead time for a job, far less time for completion than is needed, and take all the blame for it's failure to meet budget. In general expect to be yelled (read SCREAMED) at in front of the rest of the staff at any given moment for any given reason or lack there of. Expect to be subjected to constant stereotyping, racial, gender, political, etc.
