Pros
Potential exposure to a wide variety of industries. You work with new people constantly which allows you learn things from different perspectives. The annual training sessions provide a platform for teambuilding amongst co-workers. It looks great on a resume.
Cons
There is no work/life balance. There is far too much travelling. In your first year, you are bounced around to so many different clients that it's hard to ever get your bearings and you end up doing a lot of busy work. There are social clicks amongst engagement teams that tend to ostrasize other people. During busy times, Seniors tend to give you work without explaining the purpose of it and so it's difficult to grow professionally when you don't understand why you are doing something. Some Seniors have huge egos and are condescending which creates a very unpleasant work environment.
