This is a pretty good read. All top 20 business schools are tough. That link describes the collaborative nature of GBS and how students work together. Every school these days will emphasize that they provide a collaborative environment. Some do it better than others.
If you are applying RD to Emory and are admitted, you should spend some time focusing on GBS at your admitted students day. Good luck.
