Been to a lot of interviews as well. As you stated you are right about the interview process being quick. However, LIU was actually one of the best interview I had, because they asked me case based questions while other places didnt. You just go in, you just go out, there was no tour. I think that's why you didn't like it. As for the doors, the doors lead to our compounding labs or outside to the library. Maybe even to our lecture halls across to the other building.
As stated earlier, I entered this school the same way as one of the poster stated. After a year, i was like blah... I think it's just the exam though. The professors here are good, but studying is intense. I mean what pharmacy school isn't intense, people i talk to from other pharmacy schools complain about their pharmacy school as well.
You study and you pass, pharmacy school isn't that hard.
