You do know there are ~250 general surgery residencies and ~50 integrated vascular surgery residencies right? There is tremendous variability between programs in both specialties. In addition, which programs you apply to and what your aspirations are within each field are going change how successful you are in terms of interviewing and matching.
Start here:
Charting Outcomes in the Match is Here! | for the basic numbers. I will not say much about general surgery because frankly, with a 235 and reasonable letters, you can get into a program without much trouble. Having your choice of program is a bigger deal, but I can not guide you much there.
IVS on the other hand... A 235 will not close off any programs to you as nobody hard screens above that. The average in the last charting the outcomes was 237. While most people applying to IVS end up in IVS (nobody above 230 went unmatched), it is worth noting that like many competitive fields, there is a ton of self selection and the applicants that we get at our programs tend to be extremely strong. Will you get interviews with your profile, yes. But, there are several things that you are missing (or having mentioned) that are important for any competitive field. The biggest is demonstrated interest in the field. Committing to a sub-specialty as an MS4 requires you to know what you are getting into and attrition from a program that only takes 1-2 residents per year can be very hard on the program. Thus, it is generally not enough to simply say, "I like vascular, so I'm applying into it." People want to see you doing research in the field, going to conferences, doing aways, and having letters... Speaking of which, I just put together the statistics on this year's applicants. On average they had 3.3 LOR from vascular surgeons. That is something to keep in mind. Vascular surgery is a very small world. When you go to academic conferences, everyone knows everyone. For our top students on our rank list, we call the letter writers and ask about people. You need to have at least a couple of strong letters, mainly because that is what you are up against as a pool.
I am currently advising 4 current MS3 students on SDN. 3 of them are going to SVS this year. All three got the SVS travel scholarship. All are doing 2-4 vascular surgery aways (2 at my institution
). 30% of our trainees (residents and fellows) were associated with us in the past, ie. they did research with us, an away etc. This is not uncommon at many programs and having a home program generally is a big plus for this reason.
