Pros

Great benefits, including but not limited to: Fitness reimbursement, commuter benefits, professional and personal development funds. Other perks, such as beautiful offices and well stocked kitchens. The company culture promotes hard work, integrity, and performance. The employee base is made up of all stars, so it's a good environment for those who want to learn and grow

Cons

The down side of such fast growth is that there is a lack of process in a lot of areas, including formal professional development programs. I suspect this will change over time.
