When you are trying to get into a fraternity or a sorority, you might have to interview. Lot of the interview questions are geared towards who you are. They are trying to determine if your personality matches what the group represents.
Before answering these questions, it is important to find out what type of fraternity or sorority you are applying for. Sometimes a good answer for one group will be a terrible answer to another. Most of the time, fraternities are about having a good time with friends.
Finally, if you decide to join a fraternity or a sorority and you pass the interview, you will have to go through initiation. Some places are real easy, but some places can be a little weird. For example, you might have to run down the street in your underwear, or you might have to kiss 10 different people, or you might have to drink a lot. What ever it is, it's usually a surprise. Try to get as much information as you can before you join the group.
