Junior PNM in need of recruitment advice

[Future_Sister]

Hi everyone! I'm a rising junior, and I'm going to be going through informal recruitment this fall. Also, I will be completing a 5th year, so I'll be able to be an active collegian for 2.5 years, not just a year and a half. My school has 4 NPC houses, and I was offered a bid by one (though never signed anything binding me to that house, so I'm completely free to go through informal this fall!) but I know it is not where I belong.

I was hoping for some advice as to what kind of things I can ask the actives about during recruitment to show my genuine interest in their houses & to get to know them better, since I've heard the general stuff about their houses & philanthropies so many times, and I'm at the point where I want to know the girls as individuals, not just about the organization. Also, when the girls ask my year, should I mention that I will be doing a 5th year, so they are aware that I've got plenty of time to be an active sister before I graduate?

Thanks so much in advance!
