Pros
Good pay and benefits, free parking. Decent work location unless you want to get something to eat and keep working.
Cons
It's a closed organization. Either you are in the family (determined by how many friends you can make) and do well. Or you are not and you fail. Entrenched senior management that is clueless to the market realities around them and still manages the way companies did in the 80's, and still have systems used then, too. Strategy changes quarterly other than the vague 'Path To.." campaigns that are little more than platitudes they come up with every 5 years. Operations units run the company and are driven by short-term margins that are arrived at the way they calculated cost 30 years ago. There are no meaningful customer support mechanisms and the company has no clue how to deliver scalable and repeatable services. And anyone who points out all this dysfunction is doomed. So it's dysfunctional and resists any attempt to change. Avoid working at this company like you would the Plague.
