Vantaggi
Corporate South has a nice, easygoing casual environment. Hours were flexible and no one is hovering over you watching your every move, (although this does vary by department.) I personally found it to be a college campus type of environment. They have several cafeterias and little snack shops and lost of activities to get involved in. Depending on your position, you might spend a good portion of your day just walking to and from meetings which is actually kind of nice because before you know it, it's time to go home.
Svantaggi
It's all in who you know. I've seen several cases where very competent workers were passed up for a promotion just so some complete idiot who was cozy with management could slide in. The work is also not divided up correctly. Some people are just buried in work while others are sitting around twiddling their thumbs. For externals, State Farm will let someone's contract expire due to budget cuts, then turn around and hire another external a week later once the new budget is approved. Not very smart.
