Avantages
The buildings are pleasant. There is an onsite gym. Some people are competent.
Inconvénients
It's a personality driven company. If you are well liked, you can go far, regardless of your level of competence. If the cool kids don't like you, you will not be successful. Project planning is fiction, historical data about previous projects is not considered, all estimates are revised by higher-ups, resulting in all projects being delayed and employees urged to work harder than the 60 hours a week they currently work.
