i feel like preparing for the conversations you'll have is almost impossible. you can always think of things you want to bring up but you have no idea what you will actually talk about with the girls. i had the most random conversations during recruitment. you usually find something you have in common with the "rusher" and talk about it. for example, i talked about my dog...a lot hahaha
because i am obsessed with her or one day i said i wanted to be in my pajamas instead of the clothes i was wearing haha. the girl i talked about my dog with told me that she loved it because it was different...she was sick of hearing the same questions and giving the same answers over & over again. they usually know your activities, leadership positions, and awards beforehand.
just stay positive and keep a smile on your face. as easy as that sounds, keeping a smile on your face is soooo hard after a long day of talking to a million people. keep an open mind and go with the flow.
good luck!
