Pros
Pretty good compensation and overall benefits package, with some nice unexpected perks thrown in throughout the year. While the work can be stressful, everyone always acts professionally. I've never ever experienced any rudeness from a superior in over two years. Although it's a competitive field so work-life balanced is always challenging to maintain, I've found the partners and managers I've worked for do more than pay lip service to it: They encourage their people to take time off, and support you taking time for family, vacation, or other meaningful pursuits, within reason.
Cons
A lot of the work is very tedious. Management tries to make us feel like our work as a "higher purpose" with internal marketing campaigns such as "The KPMG Story," but these self-congratulatory pep talks usually just elicit an eye roll from me. High performers can't accelerate their career fast enough as promotions are very structured and follow an entrenched path.
