Pros
TripAdvisor treats their employees like gold! The benefits (other than vacation time) are the best around and the people working here are genuinely nice and smart. Truly the best working environment I have ever been in. I may have gained 10 pounds though due to the amazing free lunches and the unlimited "snack" wall.
Cons
As I mentioned above, they could be better about vacation time, especially for a travel company. You start with 3 weeks vacation, no personal days. They give "Summer Fridays" but you end up having to put in 40 hours during the week that you take a summer Friday so it doesn't really feel like a perk. Also, there are a lot of layers of management that probably do not need to exist. TA could save some money by eliminating a few layers. They can get a lot more productivity out of the staff they currently have.
