Vantaggi
If you're desperate for a job out of college they will hire you. There is always room for more drones willing to make minimum wage copying and pasting Excel sheets. That's honesty the only pro there is.
Svantaggi
Literally everything. Like many others, I got sold on the broken promises of better "work/life balance" compared to Big 4. But having worked at both, can confirm that RSM is no different. 70+ hour work weeks, travel every other day to the most random places on earth, and below minimum wage salary. Say goodbye to your mental/physical health and any form of social life. The only major difference is that you will actually make even LESS money to work here, for a smaller name on your resume, making things harder when you're inevitably ready to leave in a year (if you can even survive that long). If you're a recent college grad entering the world of public accounting because you have no other choice, just take the higher pay and better name on your resume at a Big 4. Do not believe the lies about better "culture" at a smaller firm. I've been gone from this place for over 2 years and still have nightmares.
