I have a few friends who went there. The school does not allow you to wear denim while you are there for seminary, but some girls when they come back start wearing denim skirts again. The hashkafa is similar to ateres but there are no hair rules from what I can recall. Some girls sneak in phones that are not kosher. Typically, these phones are text phones that slide as opposed to blackberrys/ iphones/ androids. They have an email service in the dorm that you have to pay $40 to use.
The most important thing in searching for a seminary/ being prepared for the interviews is to try to speak to girls who went there a few years ago (like your seniors when you were freshman in hs) and also speak to a girl who is there now. Yes, every year is different but when choosing a seminary, you are trying to grow in a way that the growth should stay with you for a long time. Also, try to come up with at least five questions to ask whoever is interviewing you. The way that they answer your questions will be a key factor in determining if you get accepted if you should go there. I asked the person who interviewed me for a seminary a question and his reaction was not so great. I got accepted so I went, but I ended up leaving because I did not notice any of the red flags until I got there (for me, the other girls had a blast there).
