Pros
Career advancement is huge. KPMG supplies great training to employees. Investing tons of time into detailed trainings that are critical to your success in the field. Also they allow you to get plenty of exposure across a broad industry. The applications and various policies you get to see early on give you a firm foundation for examining best practices. It won't take long for you to be able to pick up concepts that fortune 500 companies struggle with and the experience of talking with CFOs and other management with far more industry experience and advising them on a course of action is invaluable.
Kontras
The main downside is a lack of community can happen. Advisory will constantly be out at the client site. This allows you to get a good sense of team work with a few people, but you can be with the firm for years and still not meet with peers who were hired with you because employees are so dispursed. There is always the dredded busy season which seems somewhat tame, but even during busy season the most you are expected to work is around 50 hours a week. Higher education is not as prized at KPMG. Many managers do not have masters degrees and such as experience is prized much more than degrees. So those with years of masters degrees and doctorates and expect to make the same as new hires with a bachelor's degree.
