Rushing? (Sororities)

Can someone explain the rushing process and any steps needed to take to begin the process? I went and talked to my councilor today and she didn’t know anything about it. I’m going to a school that has a lot of Greek life so I’m considering doing it. I’m just worried that since I’m really introverted I won’t like it. I want to get out of my bubble I guess. Any advice would be great!💕
