Pros
Very PM-oriented company. Great methodologies and implementation and PM structure. Can't get much better. Also they are very M&A oriented. Organic growth just doesn't come easily to these guys. This is due to the regionalized and decentralized organizational structure. What they do is mostly at regional or local levels, not national or global. Decent employee stock purchase plan and 401k plan.
Cons
Lousy when it comes to rewarding employees. Raises are few (if ever). Bonuses haven't been doled out for going on 3 years. If you are in sales or BD, they have one of the worst compensation structures out there. Its almost like they don't want to sell anything - just acquire other companies. Commissions are rarely paid out and even then only reluctantly. Don't believe the website when it comes to CGI's offerings when it boils down to a local level. Most offerings on the website are only available in select areas around the world and not locally. Also the health plan stinks.
