Big 4 -> Credit Ratings Agency -> Top 15 MBA?

Hi Everyone,

I am wrapping up my first year in Big 4 as an audit associate pretty soon. I am taking CFA L2 in June and have already finished the CPA so at this point I am looking to leverage the CFA into a job that will position me better for an MBA in a few years. Does anyone know how experience at a Big 3 credit ratings agency will compare to working in Big 4 Audit?

Thanks
