Hey folks, let me lay this to rest. I connected with one of our admissions directors and here's the summary:
1. Everyone who interviews gets invited to campus preview day.
2. It IS NOT an indicator of anything. Does not indicate you're on the list for a prematch or a match, does not indicate your ranking.
3. Attending a campus preview day has NO BEARING on your admissions. In full disclosure, I did not attend campus preview day here or anywhere else. I got a prematch.
4. If you did not receive the invite, please reach out to admissions via email and they will resend you the link to sign up.
5. You are correct that there are less slots than interviews. That's an issue of capacity, not of admissions. First come first serve so sign up if you want to come.
