- letters of recommendation are essential - need strong ones that describe your ability as a resident. Helpful to have one for research as well I think. People with “name” can often help you out, but always better to have someone who can talk about you in detail.
- good USMLE scores, though this isn’t derm so obviously doesn’t matter as much
- research - having an abstract or two is great. Ideal if at a national conference. Publications are a great plus. You need to be able to discuss all aspects of the research you did on interviews - everything is fair game, even if non cardiology
- where you go for residency does, unfortunately for some people, matter. Cardiology powerhouses (think MGH, Hopkins, Sinai, UTSW, etc) are more likely to have the resources to help you succeed and to some degree this plays a role in how places will screen applications. That said, I went to an upper mid tier IM residency and matched well. These message boards tend to be somewhat polarized - ie either it’s people from top tier fellowships or IMGs in community programs - and most people are somewhere realistically in the middle.
- it is harder to match as an IMG, no doubt. The best way to maximize your chances of doing well is to match a strong IM residency.
