How does rush work? Different forms of rush?

Thanks Irish Lake, My college has several fraternities and sororities that are nationwide and a couple of local organizations with only a handful of chapters in the state. I believe some may be part of the NPC but then I know that there are multiple greek councils and coference with similar names so i'm not exactly sure who is a member of who and if they even follow their rules. I believe that our entire campus is all informal rush because there is no greek organization office and the unviersity only provides minimal supervision on greek orgs. They only intervene when there are incidents of "hazing" or "alcohol" related incidents.

I'm interested in how this formal structured rush works. So rushees are placed on some spread sheet and they pick and choose and the houses do the same?
