Pros
The company is making more investments to improve the employee experience. It has lavish parties, a swanky new office space with a roof deck, game room, and showers, has implemented a new employee stock purchase plan, and allocates a decent amount to professional development. Everyone strives to foster a hard-working, yet fun environment. I can always trust my peers to have my back. I am learning something new every day. It helps that my direct managers are excellent leaders and they always have their door open if I ever need career or any other kind of advice.
Cons
Depending on your department and the people with whom you work, your experience might differ. Sometimes it takes senior management a while to acknowledge it needs changes and also to reward you for your contributions. There does seem to be nepotism involved when people get promoted. In order to get ahead, I've only not had to work extremely hard, but also play the game to be noticed.
