Pros
I have worked at two Big Four Accounting Firms. I experienced the bureaucracy and career limitations that have plagued these companies for decades. Ryan offers true opportunity based on results rather than facetime and hourly utilization. I was promoted exponentially faster at Ryan than I could have ever dreamed of at Big Four. My compensation is approximately four to five times the max salary/bonus for my position at Big Four. Most importantly, I have complete control over my career path, my comp, and my family time at Ryan. This is virtually impossible at the Big Four Accounting Firms.
Cons
Not necessarily a "Con", but Ryan is not the best environment for employees who are not driven and have no interest in building a career path.
