I still think there is plenty of time remaining to be invited to interviews based on anecdotal evidence from current residents who received offers throughout November and early December of their senior years. I also know of a few people who have received verbal offers from programs where they have rotated and have not received formal interviews. Some programs are still in the early stages of sorting out their pile of applicants. Some programs won't touch your application until they have everything including your dean's letter, board score, and letters of recommendation. Many schools have not yet submitted their dean's letters.
There are some programs that seem to be cranking interviews out, however. Got an offer last week from a place that is now booked until February! They interview a hefty number of applicants, so I am not surprised that they got an early start and filled up fast. I just hope I'm not scheduling the rest of my interviews for the week before rank order lists are due!
To the OP, I sense your frustration. Some people who are exceptionally competitive or by the grace of god have had their applications complete since September may be flooded with invitations while you sit awaiting your first. Remember that big shot programs court big shot applicants the way that big shot applicants court big shot programs. Fortunately, this is not like the medical school application process, where a single applicant can hold onto a seat at eleven different medical schools until late spring. You will not have to worry about the wait list song and dance and even the guy with the perfect scores and more articles than anyone on the faculty cannot capture more than one spot. Pathology is a small field and while there are some outstanding residency candidates, there are many more applicants who do not feel so outstanding and traditionally, they have matched! This is not dermatology in that most applicants do not need a back up plan.
If you have at least a handful of interviews, then you will probably match. If you apply to and rank only the programs that you enjoy, then you will be happy with your match. If you have any doubts about your ability to match in pathology, then speak to your school dean or advisor who will have a much better idea about the competition you are up against and be able to gauge your chance of success.
