Cornell Fraternity Rush?

Hi, I’m a current Cornell freshman who really wants to rush a frat in the spring semester. However, I also want to get involved in a lot of other on campus activities, some of which have new member processes of their own. On top of this, I have a pretty tough workload as well (well, as tough as you can get during freshman year). I know that frats aren’t supposed to talk about their pledge process specifically, but can anyone give me a general idea of how tough the pledge processes are? Also, I was kinda wondering about how hard different frats haze, or at least “allegedly” haze?
