Pros
They have a lot of perks (free food, elaborate kick off events, great parties, decent salary) and you will find a bond with teammates that promotes real comradery.
Cons
There is a very bad culture underneath all the bells and whistles. Senior HR people are friends with senior leaders giving their abusive behavior immunity. The promote obedience over skill every time. It is expected that you "smoke and mirrors" with your engagement scores, c-suite can be aggressive and often verbally abusive, and that trickles down in to all leadership. There is a clique culture and if you are in the in crown you are untouchable no matter how bad your performance. They motivate with fear and having a husband wife scenario makes bringing issues to the top extremely challenging.
