When discussing your major, you can explain why you chose it, what classes you are taking and possible career interests.
Regarding involvement, speak about any clubs, sports or professional organizations you are a part of. Why did you join these? Were you involved in these extracurriculars in high school, too? Any detail helps the sorority member gauge who you are and your day-to-day life.
If you’re not a part of any extracurriculars in college yet, or are not sure what you’re interested in, that’s okay! Discuss how you want to learn more about how to get involved on campus or what interests you might like to explore through extracurricular activities. The sorority member could suggest activities you were unaware of, opening the door to new possibilities.
