Not an attending. Am a Fellow.
Tread lightly when breaching this topic. This is a very sensitive subject. Lots of things come into play. Region, application, variety of programs applied to. I'm african-american. Was an average applicant when I applied 6 years ago. Got interviews at some great programs and ended up in a great residency program. Not only am I african-american, but I came from a pretty impoverished background (inner-city, poor, child of single parent, etc.). I only mention that because most of the people in ortho that I have come into contact with the past 6 - 7 years are not from that sort of background. With that said. . . . . . .I can truly only recall only 2 or 3 times that I have felt out of place or unwanted during my training. That counts residency, national meetings, conferences, interviews, etc. I'm from the midwest, and trained in the midwest, so the climate may just be different.
If any thing, I saw race as an advantage. You show up on interview day and there's seriously 40 6-foot, white guys, with dark hair in black suits. Then there was me, 6-foot-3, black guy in a black suit. Who do you think they'll remember best? I was also a Jock, so that may have helped me out a bit too.
As for the paucity of interviews. . . . . . . . . .there has got to be something that sticks out about the application. It could be board scores, a bad LOR, odd personal statement, a bad rotation grade, your program origin, poor selection of programs to apply too (i.e. applied to "upper tier" places w/o any "lower tier" places in the mix). Knowing the review process at my residency program. Choices of whom to interview was based on board scores, LOR's, grades, research/publications. . . . . . . .not race. Just my anecdotal experience.
