First, know why you are trying to join a fraternity. People rush for many different reasons; some want a resume booster, some want to find a family, some do it because their parents want them to. Don't rush a fraternity for other people, do it for yourself. Fraternities are trying to avoid men who just want to join; for partying, to meet girls, or to just make some friends. If you say these are the reasons for joining, organizations will probably not extend you a bid. While we all are in social organizations that occasionally have parties and have socials, that is not what we are all about.
Second, ignore the campus stereotypes. Don't let people make your decisions for you. Some people may refer to a certain fraternity in a positive light, some may refer to it in a negative light; the point is, people are unreliable and there is no better source than your own judgment.
Third, do your research. Go online to the fraternities website or find them in the breezeway or place they usually meet to advertise. The best time to do this would be the first week of school, in the fall, because ALL of the fraternities will be there. For FAU each fraternity has a table in the breezeway advertising for their chapter. Find out how many fraternities there are, what type of fraternity each one is, and what the rush events are for each one. Even if you have no interest in rushing a particular fraternity, take a rush flier anyways; your opinion might change later.
Fourth, narrow your options. Most likely, there will be way too many fraternity events to hit in one week. Make a quick character judgment when you're picking up rush fliers, and decide on which ones you would most likely get along with. Don't pick a fraternity because they hold the best parties or pull the most girls or because they dress the best, pick a fraternity because you like their character.
Fifth, be yourself. This is one of the most important parts. Despite their reputations for being meat-heads, fraternities can spot superficiality very easily. Be comfortable, confident, and RELAX! If a fraternity doesn't like your personality, find one that does.
Sixth, be upfront, don't lie. It can only hurt your chances of getting a bid.
Seven, talk to everyone. Not everyone in a fraternity is the same. There are many different personalities in every fraternity, and if you don't like one person's personality, find another person. If it turns out you don't like anyone in a particular fraternity, then that fraternity is likely not right for you.
Eight, ask questions about the fraternity. Asking questions lets a fraternity know you're interested, and more importantly, fraternities love talking about their chapter or national history. Find out the time commitment, the financial commitment, the perks, the downsides--whatever. Good questions are, "What is your favorite memory in the chapter?" and "Why did you join this fraternity?”.
Nine, narrow your options again. When you've been to every fraternity that you think you might get along with, pick the ones that you know you'll get along with. A good idea is to narrow it down to the two you have the best rapport with, else you risk not receiving a bid, and moreover that will lead the fraternity you want to believe you're not serious about joining. Besides, having two top choices makes a fraternity compete for you. After you pick these two, spend the remainder of the time rushing them. If they like you as much as you like them, chances are, you'll get a bid from one of them.
Ten, remember, that if you don't get a bid from one of your top two and you still want to join--keep rushing. Hang out with them outside of rush week, on a more personal basis. The few that you hang out with will most likely convince the rest of the chapter that you're a right fit. Most of the time, a bid isn't offered because they solely want to wait and see if you're serious. It's not the end of the world either.
