Cons
Promotions can take little bit more time than as compared to other companies. Some times company may not give annual salary increments. Onsite opportunities are very rare and if they exist it would be mostly short term and even in that you cannot make money(from per diem) as company would keep you in the best of hotels and provide you with the best of transportation and best of food but for all this company would pay directly. Its not like you can save anything. So you can work and enjoy your onsite stay but saving some money is not possible unlike other IT-Service based companies which pay you some money in cash for food and transport etc.
