Pros
People are truly helping each other rather than competing or politicking or backstabbing. An extremely collaborative and caring environment that allows you to do some really interesting work with super smart people.
Cons
Some instability in the past couple of years that was addressed with changes in leadership. Not all of these changes were handled or communicated well. The shift to hybrid work has not been without issues, which is probably true to all companies. As any consulting company, one partially inherits the structures of the client organization and being a consultant is both a blessing and a curse; it allows you to do things the locals are not allowed to do, and to avoid some of the structures and internal politics. At the same time you are expected to do more and be better and more productive.
