I got the interview invite about a week ago, my roommate did as well. I am a VA resident from a rural area and attend a school that is well respected by PSU (Lehigh U.), so that might have helped. I don't know, this process is very random. My roommate is a reapplicant from NJ who graduated from Lehigh last year and is working in a lab for the year; she did not previously apply to PSU. I don't want to offend anyone by posting our stats so I won't unless you really want me to. If it makes you feel any better, I have heard that PSU starts pulling some people off the "hold for interview" list in February, so some people from the list do get interviews. but I am not a pre-med advisor, so don't quote me on it though. Good luck!
