Morale at all time low

Pros

Some cool people. Starbucks in the office. Nice place to sit for lunch with buddies.

Cons

Morale is at an all time low. There are no raises or promotions. You’ll be told to “just wait” for months on end. No one is happy. Everyone is on edge. Company culture is next to nothing at the moment.
