Pros
Stable job, with easy working hours. Flexible work environment where telecommuting is allowed. Great opportunities for career development through training. Great for increasing your knowledge. Standard practices and processes allow for relatively easy integration and minimal ramp up time to learn the basics of the organization. From a consulting perspective, CGI's internal tools to monitor budgets, resource allocations, and progress are excellent. Depending on the group or manager you work for, great flexibility to manage personal commitments. CGI encourages community through certain programs and social events. Social events tend to be geared towards employees with young families. Great discounts offered through social events.
Cons
Boring work depending on which business unit you work for. CSB was very limited in their vision, and have no real clue on what life will be like once BCE is privatized. Any initiatives brought up for discussion are usually ignored. Business development (aka sales) is NOT compensated on the size of the deals, thus acting like a glorified administrator of consulting contracts. Sometimes it feels like everyone is unionized, and has a "union" mentality where only the minimum should be done. Little to no innovation, little to no intellectual property, little to no focus in on increasing intellectual capital.
