I'll say it again. This is a long slog for those who are reading and evaluating applications. We start around the time college football starts (late August) and we keep reading and evaluating right through early December (Army-Navy Game). There is sometimes a bit more to read right through the bowl games, particularly at schools that have interview schedules that run into February or later.
We are only half way through October. There are at least 6 more weekends of college football so cool your jets. You can't cry about no interviews until Black Friday (why it is called Black Friday, right?). This is an exhausting wait but there is no way around it. The readers are reading as quickly as they can without being overwhelmed and having everything blend together resulting in mistakes that can cost YOU an interview. The way the work is assigned, you might be the first of 60 that a reviewer looks at in a two week period and sends on for an interview or you might be the last and that could be 2 or 3 weeks later (if we have a 2 week deadline sometimes it is 3 weeks before we finish). And they aren't being assigned to readers FIFO (first in /first out) but might be sorted and ranked in some way (preference for in-state zip codes, or feeder schools, or MCAT/GPA, etc).
