Pros
Name recognition. The quality of employees is fairly high, mostly intelligent people. Some decent perks like dinners and lunches paid for by the company.
Cons
Terrible promotion process. The performance rating system is completely subjective. There is little visibility on how people are reviewed. You have a few people who either make or break your career. You may end up having a ridiculously unintelligent and incompetent supervisor who will destroy your chances for promotion, and there is little visibility on how he or she rates you. The rating system is completely determined by peoples subjective view of you, rather than your actual performance. If you find a manager or career counselor here then stay, otherwise you are set for a mediocre career at Accenture at best
