Pros
Decent learning environment where most people try to help out. Managers are a great resource and will make you more proficient at what you do. The learning curve is extremely steep and you can learn a lot in a fairly little amount of time. Formal training classes are top notch with great instructors. Mentor networks are also highly encouraged and useful. Flexibility when it comes to hours is also good. Overall, surrounded by extremely bright people who are, for the most part, down to earth and easy to get along with when working long hours. Great place to work as a first job out of college to learn quickly and advance faster upon leaving. The name is highly respected in industry.
Cons
Long hours and merely average pay. Tasks as an auditor can often become very routine and mundane. Often you will be left to the wolves and partners are not as knowledgable as they should be about subject matter. No true bonus structure. Hard work and going above and beyond maybe rewarded with a $100 gift certificate which strategically comes at Christmas time. Simple thank you's are also hard to come by for a long week's work when trying to meet impossible deadlines.
