Avantages
Good compensation, excellent benefits package, cafeteria and gym onsite, and they pay for education. Good work-life balance, except during the tax season. It is possible to get away without working much, and many people do.
Inconvénients
People are mediocre at best, lazy and incompetent at worst. Managers yell, scream, and call people in to work on Saturdays. Meetings take a better portion of the day, and it's important to go and agree with the powers that be. People are punished for bad decisions, but are not rewarded for good ones, therefore it is very hard to get to a decision at all. Discussions go on for weeks and months. There is a general culture of firefighting - the most brownie points go to the person fighting the biggest fires, never mind that those are generally the people who caused the fires in the first place.
