Pros
Accenture is a large organisation where as a young graduate you can learn a lot. It's range of services, industries and clients give plenty of opportunity to work with leading market players at a global level. The opportunity to learn is powered by a structured management of knowledge and by the breadth of resources you can reach worldwide. Working with smart people and as part of large scale programmes provides a very interesting environment, especially in the early stages of a career. If you can stand lot of travelling and don't want to get out at 5, on average you can still have a good work-life balance.
Cons
Accenture is a big corporation and as such it has lost some of the "personal touch" it had years ago. Bureaucracy, over competition for few places on top, a not very limpid performance management process come with the pack. There is a risk of getting lost in the crowd if you don't work for the right group of people and you don't pay attention to the "politics" of relations. Majority of people are brilliant and sharp so if you don't make more than a good marketing of yourself, very hardly you can get to the top level. Salary is reasonable but not “over exciting”
