Pros
The environment is very friendly and people are very easy to get along with. The office space is very open and give you a lot of desk space. They also have great amenities with a coffee bar and monthly happy hour host by the company (free food and drinks!). Depending on your department they are fairly flexible with you schedule.
Cons
There wasn't really much room for growth. You can put forth great effort but if you are not on the good side of the management you will not get the promotion you desire. Lots of politics played in the office, if you like playing that game then this is the place for you. They tell you that they like to promote from within but when the time comes to have people move up and get promoted they hire someone else in the place.
