Vantaggi
You can negotiate a good contract rate because contractors don't want to stay there for very long.
Svantaggi
Sweatshop environment. You will be harassed by programmers from India, because they believe in that because you are paid a good rate, you don't deserve to work in a professional environment. The Indian Programmers that work there are not statistical programmers and do not have a pharmaceutical background. You will be asked to verify programs with incorrect specifications, and when you document why they are incorrect management will ignore it and tell you to work faster. When you are creating programs in development, you won't be given any specifications. Very poor SDTM standards which do not pass muster with the FDA. Since management doesn't care at all about quality, they should simply have their Indian programmers do all the work and they can then deal with the 1000 questions from the FDA after the submission.
