It should be before the interview, which is good.
Could be that the embassy does not have the medical information yet on the interview date, since its “just” 3 days, but with everything being digital, it could be there as well.
My medical was a month prior to the interview appointment.
In case it wouldn’t be there in your case, the visa does not get issues right away and the officer waits for the medical, then issues the visa, if approved.:) But that might be just a matter of a few days,
