Pros
Low stress; easy, non-demanding work; mostly work eight or less hours per day; little to no travel; the people who work there are mostly nice.
Cons
Work is not challenging, and there is little to no career advancement; management is poor, and untrained, and often seems to be hiding bad news from employees (management is overly optimistic). Also, salaries are too low, with poor raises, and benefits. There is also too many non-Americans with visas working there, which is probably why salaries are low and the benefits aren't good (the non-Americans don't even realize they are being taken advantage of, when it comes to salaries and benefits). If you are American, you are definitely in a minority, and may feel alienated, and would probably make more money and receive better benefits at another compnay. CGI has abused the H -1B visa system, and uses off shore people as much as possible.
