Thanks NecFas, been seeing your posts around here! How many programs did you apply to? By my estimate, about a third of DR programs (around 60) have taken more than 20% DOs, another third have taken between 0 and 20% and the last third don’t take any. Based on this I was planning on applying to around 80 programs. Is this too many?
I planned on doing 60-70 pre-COVID but upped it to ~80 'cause I wasn't sure how the season would play out with all the craziness, so I think that probably is a perfect amount.
Center most of your apps around your "target level" (e.g. for me it was mid-tier academic) & then toss in a few community programs as "safeties" & a few "reaches" you'd love to match at (esp. think about adding the "reach" if you have ties somehow to the region.) Make sure to include programs you have connections to (e.g. hometown & area you go to school at) just to make sure you reach your target interview goal (12-15 is normally recommended; as a DO I'd shoot for 15 just to be super safe.)
As for DO friendliness, if they have any DOs at all, consider it "DO friendly." For programs that have none, keep in mind it doesn't necessarily mean that they don't interview DOs (esp. in the case of mid-tier academic & mid/upper-tier academic programs.) They may have just not matched one in the past few years, so if you're genuinely interested, go ahead & shoot your shot.
Also, I'd recommend thinking about what your top 5 programs are too (this may change as the season goes on, and that's okay) & consider sending them
genuine letters of interest explaining why you'd like to potential match there (esp. if they are in a highly desired region like Colorado, PNW, CA) or in a state with only one radiology residency program (e.g. New Mexico.) Don't send more than 5; people that spam LOIs all over the place are the reason some programs don't take them seriously anymore. Make sure to send then after maybe 2 weeks of applying (I missed 2 interviews I could have had 'cause I waited too long because I was afraid of sending too early & coming off as "pushy" or "overly eager." Send them after 2 weeks.)
