As someone who went through formal recruitment for a sorority and has recruited while being in a sorority, I noticed a lot of similarities too! The match is pretty much the same as sorority rankings, where potential new members rank the sororities and the sororities rank the potential new members based on their stats (GPA, awards, service/leadership experience) as well as how well the conversations with sorority members go (think a suuuper casual interview). During both processes, I've heard the phrase "You choose us just as much as we choose you!" and there is a strong emphasis on fit. Recruitment went very well for me, and hopefully the match does too!
