Rushing as a sophmore

I’m interested on rushing, but i’m a sophmore in-state student. I was just wondering on what the overall process and stereotypes are? I’ve heard it’s harder for sophomores and honestly I’m not sure if it would be worth it and if sophmore is rushing have a good experience. I also am a little nervous on being judged based on looks and other external factors, and I’m not if UNC sororities are like that. I also come from a high school that doesn’t typically have a lot of students involved in rush.
