My most important piece of advice is not to ask the PNM the ever ominous and irritating question: "So, do you have any questions?" It's something that far too many women fall back on when they can't think of anything more intelligent to ask. It was one of my hugest pet peeves as a PNM and as the recruitment chair.
I know there are some shy girls out there who need that opportunity to ask a question, but for the most part in my experience, these young women will ask questions if they have any.
Come up with some original questions of your own, to where if you can't think of anything else to say, you have this "back pocket" question that you can ask...for example, "Did you go to any concerts this summer? What is your favorite type of music?"
Do yourself, and the young woman the favor of not asking what year in school she is, or what her major is-- I felt that at the end of day one when I rushed that if someone asked me that question again I was going to scream as they could have read that off my application.
Finally, make a friend...that is what these women are here to do, make eye contact with them, and for goodness sake remember their names!!! And don't be touchy feely with the girl if you don't feel that she is that kind of girl, it just makes some people feel uncomfortable. Have fun...recruitment was the absolute BEST part of being a collegiate, and I encourage those of you who are new or are considering it, to really think about becoming a recruitment chairperson.
I am now stepping down off of my soap box.
