Pros
It's a great place to start your career as it has many opportunities to move around various departments when you find an area you are interested in. Promotion within teams are not easily acquired, however you can get promoted by moving accross different teams. There is good opportunity to make a long term career in Accenture. There is also opportunity to gain excellent experience.
Cons
The working hours can sometimes be long, however this depends on the type of work you are doing as well as the culture of your team (some work hard others don't need to). There is little room for rewarding staff for good work/achievements. Also, some teams work are very repetetive and boring. Staff turnover seems a bit high, so you are nearly training in new people at least once every year. In general I enjoyed working with Accenture, the people were fun and very smart, but I ended up leaving as the salary was quite low compared to what the market was offering. If the salary had remained competitive, I would probably still be working there, as I enjoyed the challenging work environment.
