Pros
Many people here are hard working, kind and driven to innovate the product. All the tech "perks" without being obscene. Dogs allowed, founders still run the company.
Cons
Nightmare infighting, everyone is conniving and clamoring over eachother for their little fiefdom. Very few are pulling together to make sure that PINNERS and PINTEREST win. Inexperienced and insensitive middle management. Management has no idea what they are doing, and make mistakes so galling that will get Pinterest sued. If you are not a sorority sister or fraternity bro stay away. This place doesn't want anyone different, but it's also full of cowards, so they will all pretend to accept you. If you are joining this company, keep a BIG smile no matter how atrocious people act and don't trust anyone. If you show an inkling of disillusionment, you are ostracized.
