Pros
KPMG is a resume builder for future jobs. Additionally, if you see your life goal as becoming a partner and securing that massive salary while completely detaching yourself from your family and friends then it is a great place to build a monitarily wealthy career 10 - 15 years down the line.
Cons
KPMG spends significant time promoting its brand and selling itself as one of the greatest employers to work for. While benefits are good, they are coupled with and rather negated by low salaries (considering the time and knowledge commitment required to perform the job) and very long hours. 5 weeks PTO is somewhat negated by the massive overtime commitment. With large jobs the firm is frequently successful in billing for its employees’ overtime and all such billings largely go into the Partners’ pockets. KPMG very sneakily appeals most effectively to its core demographic, i.e. recent college graduates (typically 26 and under). As part of this core demographic we are treated as the minions of the firm and are drawn in through the firm making use of such techniques as plying us with alcohol and bringing us in as a cohesive "starting class" in order that we feel a certain bond with our peers and thus feel guilty about saying a bad word about the firm.
