In the complete email that Davis sends it says "
If you have not taken the AAMC PREview exam, you will not be eligible for an interview invitation until a score is recieved. The latest AAMC PREview exam date we will accept is 9/23/2022. Applicants who do not complete the PREview exam will not be further considered for admissions. Applicants can recieve a secondary application without the PREview exam, but will not be considered for an interview until a PREview exam score is received. "
So to answer your first question they do not send interviews until they have received a score. To answer your second question, the earliest MD schools can send admission decisions is October 15th (unless they are an Early Decision school and Im almost sure that Davis is not)!
Hope that helps
