Pros
You gain exposure to working with USAID. You also understand the complexity of bidding and winning/losing contracts with the US government.
Cons
Due to the incredibly high turnover rate they constantly promote under qualified staff to managerial levels who are simply not ready to take on such responsibility. There are a lot of cliques and the employees are too ideological for their own good. They pour on work that they promise you is to help other people abroad, but in reality you are ruining your own life in order to set up projects that have very minimal impact in the third world. I was surrounded by 24-26 year old "managers" who lacked serious maturity. The senior level management were abroad so often that they weren't around to spend enough time to see what was going on. I would not recommend this company to my worst enemy.
