Sororities at UW

My d is thinking of rushing this summer. I went to a college without Greek life so am totally unfamiliar. Does anyone have direct experience of the Sororities? My d has 2 Varsity letters and works hard but also likes to have fun, she is a track captain this year and also was chosen as a leader of a retreat for the junior class and got great feedback from the kids and adult leaders. She makes friends easily and has a very diverse group of friends, boys and girls. She is not snobby or materialistic. We live in the Seattle area. She is very caring and would hate a bitchy, cliquey or exclusive environment.
