Not sure if this helps much, but perhaps it will add more data to help form the overall perspective:
I seemed to have a strong application and "did everything right", yet I did not match.
I went to a fairly well respected American medical school, where I was an average student. Most of my test scores and evaluations hovered around the 45-55th percentile marks, with the occasional one up to 75th. By the time I applied to residency, I had taken USMLE Step I and Step II, and passed them both with, again, rather average scores.
No big deal, I figured. Of course I would have liked to be a stronger applicant, but I was still sitting better than half of my class, which was saying something. I even had several publications and presentations at national conferences under my belt.
In contrast to some who go into pathology, I had pretty extensive med school exposure. My 4th year was practically all pathology, both AP and CP rotations, and even an away visiting rotation. Pathology wasn't my back-up plan; it was my primary goal. I had also worked 15 years in various fields before going to med school, working with the public, other professionals, and having some leadership roles as well. Everyone seems to find me as an agreeable, easygoing, polite and responsible person. Maybe I'm somewhat more socially reserved than average, but in the numerous mock interviews I performed (with 6 different people over a 4 month period), I received positive feedback on my friendliness and conversational ability.
I had letters of recommendation from pathologists I had worked with, as well as one from a surgeon I had been working with in clinic for over two years and one from my research mentor (an MD) who I'd been working with for over three years.
I applied to about 30 places, a wide variety across the nation, both big and small, public and private, hospital and small practice. Got 12 offers for interview, interviewed at 9, ranked 8 (about half were strong names, about half just average, and no I didn't just rank the big places first). Did not match.
It especially hurt during the scramble, when I saw that 3 of the programs I had ranked still had openings, which meant that they didn't rank me. Not even the small private practice place where I had been the first American grad to interview there in 7 years... Not even the place I did an away rotation at ranked me.
And, the star player of my class didn't match either. She was just going into general surgery, had 270+ on both Step 1 and Step 2, and was a social darling and dedicated hard worker.
I guess the moral is that sometimes, things just don't mesh in your favor. :/
