Pros
Large organization with options to travel, and good brand equity to be considered for future roles at other IT consultancies.
Cons
Large orgs come with internal politics. I tried advocating for years the area of Capgemini I wanted to transition into but had a lot of trouble leaving the practice I was hired into. Given it's a large org, myself and many others also got pigeonholed into a specific niche role that wasn't very transferrable--if you ended up wanting to help with business development or a PM capacity, it was my experience that it was hard to even get in the room or be considered if you didn't have 6+ years of experience. Ended up getting laid off and only given 1 month of severance despite 4 years of service. No budges even after trying to discuss about it. Ironically helped put together a proposal that took months in the making, got laid off when there was no immediate projects in the pipeline for me, then the large deal I drove got sold a month after I was gone. Seems like there was a disconnect or gap in information with higher leadership on what contributions I was making and felt like I ended up just being another number rather than fostering my growth.
