CGI recruited at my school. I was able to do a first-round interview on grounds. It was a very informal interview. We pretty much just had an open conversation without any direct questions. I got a callback to go to their location in northern Virginia for the next round of interviews (2 were scheduled on the same day). The first interviewer was younger and asked the standard questions that are on the list - pretty straightforward questions. Next interview was with a more senior lady who was much more informal and conversational. She didn't ask any direct interview questions - just made friendly conversation about interesting things on my resume and her own background.
