Pros
Populistic actions (e.g. parties, events, lunches, etc.) which some of the naive juniors take for granted... and get brain-washed. This company is cashcow... it will undertake any business activity that brings money for the least effort and risk, and then, once it stops being profitable, it will shift right to the next profitable one.
Cons
Promotion is based on obsequiousness, cheating, deception, falsehood and a lot of politics... Skilled consultants (e.g. juniors, seniors) get nonsense reasons for not getting the well-deserved promotions. PwC actually needs skilled people to remain on low positions just to keep low hourly rate for the firm's profits. Very often, managers take the credit of theam members' good work instead of recognizing the merits of those who actually did the job and acclain themselves subject matter experts, when in fact they only scratch the surface of that specific matter. Tully skilled people are not involved in projects from the very beginning, but rather when things start getting messy in the project and there is high risk that customers might be unsatisfied...
