Pros
It's a good place to start your career. Out of college, it's a fantastic way to learn how to work, how to manage projects/competing priorities, attention to detail, serving clients, and how to keep grinding. If you earn your manager's trust there is flexibility in your schedule. I was able to see past the smoke and mirrors early on and felt really jaded long before I left. However, after some time to reflect and starting a new position, I was able to see how valuable the project management and soft skills I learned really were. 6 months ago I would have given it 1 to 2 stars, but because of the skills i took away I felt compelled to go with 3.
Cons
You are an auditor, not a consultant. They try and make it sound better than it actually is when they pitch you on the job. However, when you realize you're not a consultant, you can end up feeling like you were duped. Office politics are rampant and the actual material is extremely dry. Since it's all about the clients and there is a huge amount of pressure from management, the stress levels skyrocket and it all rolls downhill to the consultants. At the end of the day, the stress being thrown at you over a SOX AUDIT is not worth it. Especially since the compensation is not adequate for the amount of work (You do the same thing as the Big 4 but for 10%-15% less). Turnover is huge - I witnessed 9 people leave my small office in just a few months.
