Vantaggi
Everyone is very nice and most people are pretty outgoing. Colleagues at every level are highly responsive. Everyone is focused on delivering excellence to clients. Funding for team building, training, social outings, BizDev, etc seems incredibly abundant. >5 weeks of vacation time. Dollar for dollar (up to 6%) matching on 401(k).
Svantaggi
The people are generally average or above average. There are very few really stellar people who stick around. Managing Directors get to that level because they can sell, not because they're good leaders or good at developing talent. There is a significant bias that favors those who have spent their entire careers at Accenture. They often say working 1 year at Accenture is like working 3 years anywhere else...this is really not true and is indicative of the overly high opinions these "leaders" have of themselves. Not as many "leaders" have advanced degrees as you'd hope/expect.
