I don’t remember much about my interview, but one question that Rabbi Geisler commonly asks is what you want to work on during your year in seminary. He told us that that tells him what the girl’s strength is, since human nature is that a person wants to work on what’s easy for them. So if you say you want to work on tefila, or tznius, or whatever, he’ll understand from that that you excel in the area.
Otherwise, I think it was pretty comfortable and nonthreatening. Relax. Hatzlacha.
