Hi all - I messaged the Silberman admissions ambassador chat box and this is what I got:
"There was an error in the system last night and many people who had not yet been moved to pending interview status were sent invitations. We are currently reviewing all recipients to see who was erroneously sent this invitation and will be following up with those who are indeed pending interview soon with more dates as soon as the system is back online after having been overloaded."
I hope this is helpful! They are online at https://sssw.hunter.cuny.edu/admissions/ if anyone wants to reach out themselves.
