What's the point of skits?

[psy]

My alma marter stopped doing recruitment skits a few years before I was a student there, but I've read about them on GC, and honestly, I don't really get how they are supposed to help in the selection process. Okay, maybe you get to see how a few of the sisters work together or what they choose to focus their skit on, but it still seems like that time would be better spent actually having the PMN's and the actives *interact*, especially given how relatively short recruitment is.

Can someone please shed some light on how skits are helpful in practice, or the logic behind having them is part of recruitment?

Thanks!
