You will be asked some version of these all week. You shouldn't script answers, but you should have thought about them once before you're standing in a loud room in heels.
"Why do you want to go Greek?" The trap is answering generically ("community, sisterhood, involvement") because everyone says exactly that. Answer with something true and specific: your sister's chapter experience, wanting a home base at a huge school, watching your mom still travel with her pledge class. One honest sentence beats three brochure ones.
"Tell me about yourself." Have a 30-second version: where you're from, what you're studying or into, one thing you're excited about this year. Then stop talking, this question is an invitation to a conversation, not a monologue prompt.
"What are you involved in?" Pick two things you can talk about with actual enthusiasm rather than listing everything. Enthusiasm is the data point, not the resume.
"What's your major and why?" "Undecided" is a fine answer when it comes with curiosity ("I'm deciding between nursing and psych, I'm taking both intros this fall"). What lands badly is apologizing for your own answer.
"What do you like to do for fun?" Have a real answer. "Hang out with friends" is a non-answer. Reality TV, running, thrifting, cooking badly, all better because all conversational.
And the questions to ask back, because the best conversations go both ways: what's your favorite thing you've done with the chapter, what surprised you about joining, what are you involved in outside the chapter. Members answer those honestly, and their honest answers are how you rank at night.
