After a while of lurking on this website I thought I'd give back to WSO and answer any questions about the big 3 ratings agencys.
There was a thread from 2013 which was similar but thought i'd give some fresh thoughts as it has been 6 years since. I have just started work at a LevFin BB so I cannot echo enough that a ratings agency is a legitimate pathway to high finance if you put in the effort. Have some other colleagues who have also moved to buyside debt shops and other LevFin roles from the RA's.
Ask away! Culture, hours, exits, pay, etc
