OPEN HOUSE postcard = come check out our school
INTERVIEW INVITATION = come so we (admissions committee) can check you out
OPEN HOUSE postcard does not equal an INTERVIEW INVITATION
Receiving an OPEN HOUSE postcard does not guarantee that you'll receive an INTERVIEW INVITATION in the future
It's like this, you go to McDonald's to eat (OPEN HOUSE), you're not there to apply for a job (INTERVIEW INVITATION).
Hope I cleared things up.....sorry to bust your bubble, but an OPEN HOUSE is just invite for you to visit the school. People that attends OPEN HOUSES includes high school seniors, college students, family members, people that applied to AADSAS or anyone that is interested in applying to that dental school.
Why did you receive a OPEN HOUSE postcard?
A: the dental school received your name and contact information from the AADSAS application and the school feel that since you've applied to them, you're interested in them. So they send you an OPEN HOUSE postcard saying come and check us out!
