Pros
The people that Accenture attracts for the most part are superb. There is a great diversity of backgrounds and people with many different skill sets. The ability to work from home when needed is also helpful. Accenture also provides very good training courses.
Cons
HR is highly frustrating to work with and very ineffective, to the point of being the last straw when people make a decission to leave. Salaries are well below market rate - especially for the type of people and skills they deliver. Each year, at least in the US, it seems as though the people that make the company what it is are de-valued by lack of promotions, lack of increased pay, lay-offs and those who are left have to pick up the slack without any compensation or recognition.
