Pros
Well-defined processes, financially disciplined, pockets of brilliance around the world, good learning grounds for aspiring consultants and directors
Cons
At the end of the day there is no hiding that CGI is a body shop that is 1 tier higher than the Wipros / HCL / Tatas of the world. Directors spend most of their time addressing a laundry list of company metrics on which they are grilled on a weekly basis. This would normally be reasonable but a Director at CGI is expected to find a potential client, find a suitable service, pitch it, write the SOW, staff it, run it, and keep the client happy, all while managing his/her direct reports AND stay 50% billable somehow. There is no dedicated sales or marketing team - you are truly a team of one and due to the geo-centric nature of the organization you have to beg others for help and those not in your region who do will do it reluctantly. The way you are measured and the company is structured (zero tolerance for bench, we start firing people about 1 month in) means that you pretty much have to own 2-3 large multi-year outsourcing clients to "pay yourself" and be successful. Hiring and firing is haphazard - people are often hired for one thing then gets bait-and-switched due to contracts that fall through and then people are fired when a project ends due to the lack of tolerance for any bench. Even when you are a director or VP your existence is very tenuous - there is no loyalty and you can be let go at any moment. This place is a revolving door - might be a good place to pick up some experience but applicants beware.
