Pros
Great work life balance, they understand that employees have lives and the goal is to do your job not just show up in a specific location. It is a truly global organization so the opportunity to interact meaningfully with a wide range of people is very real.
Cons
Elsevier can be very euro-centric in how people are promoted and treated. When I was there it was much more common for Europeans to be promoted into senior U.S. based positions than the opposite. It came across as a glass ceiling for Americans. Getting things done can be tedious. There are layers of internal departments who main function appears to be form completion and project delay. This is common to many large organizations so it's not a unique problem. It did get worse over time though as more MBAs entered the business.
