After interviewing at 10 schools, we concluded: AOs vary greatly, from those that were rude, disinterested, disorganized, desperate, spent the whole time talking about a sport my child would never play, got our name wrong (repeatedly)........ to awe inspiring gracious highly educated, caring and curious folks that had us ready to sign on the dotted line that instant, and brought out the very best in our family effortlessly.
Some are very, very good. Some are polite and OK. Some should find another field.
The very, very good AOs were NOT always at the schools you would expect. Try to separate your experience with the AO from your feel for the school (which is pretty hard to do but very worth it). Once you get to the school, you are unlikely to ever see the AO again.
