Avantages
Clients have good budgets, it's all about the projects and making sure resources are properly allocated.
Inconvénients
Management is non-existent. There's no leadership, just nepotism. Too many mediocre people with a "manager" title who do nothing, yet get ridiculous paychecks and will never get fired. They are slowly sinking the ship, wasting resources and never caring about the work or people. Most of the time nobody knows what they do or where they are. The rest who actually work all day and do great work are unappreciated and eventually leave or get fired. There's no innovation, and any attempts to do something great and implement successful business practices are shut down by management. Sometimes, this is even condemned as upper management is afraid people will actually realize they do nothing, even if everyone already knows. Most people don't really care about their teams. You're completely disposable.
