Pros
They pay well. They put on numerous social events to blind you to how dysfunctional they are. Some nice people in places, including some of the most senior partners. You won't feel the knives in your back until the end is near.
Cons
I'll preface this by saying I spent many years at another Big4, so this commentary isn't coming from a place of, "you just don't understand the partner track!" etc. The good folks can't motivate most of the directors or managing directors to do the right thing. This is particularly glaring in business development. The account leads couldn't give a care in the world about increasing the billable hours to the client unless *they* generated the work. The interaction between Risk Assurance and Advisory is more like the interaction between Goldman Sachs and JPMorganChase. One group will actively kill deals significant to your "team" because they don't want to "deal" with the independence issues, or deal with you, or talk to the client, etc. Never worked at a place that would so easily leave six figures on the table because of infighting. There have been a lot of hires with no consulting experience that have been installed as Managing Directors, and don't understand how the sales cycle operates. Do you like people that leave you review notes that say, "You should put a comma here", rather than just turning on track changes and putting in a comma? You'll love PwC. Do you like to spend 20-30 actual hours of your time putting together slide decks for $7,000 worth of work that PwC isn't even qualified to do? This is your place! I enjoyed cleaning fryers at a fast food restaurant many years ago. I liked tossing rotten produce out at a big grocery in the middle of the night. I did not like the vicious, backstabbing, dishonest culture at PwC.
