Wow! That's a very complex equation- I'm impressed
I interviewed at programs that are very similar, but looking at the interview list generated on this forum, there are a huge variety of programs in terms of size, location, and "focus". So, with that caveat, from my perspective, these were things I thought were important and will drive my rank list:
1. Good mix of hematology and oncology- every program has oncology, and I know hematology is not everyone's thing, but it will be on the boards. It also makes sense to me to know both subject well since we'll be boarded in both.
2. Lots, and lots of varied patients. I remember during residency that some hospitals would say, the majority of brain tumors went to x hospital because of proton beam therapy and surgeons, etc, but we get all of the x disease. I'm sure that was an exaggeration, but I looked for places that had variety and were in a location without much competition.
3. Mentorship/ research support- ultimately, I think this is the most important one. Having mentors invested in you and your career will make all the difference.
As far as small details, call schedules, facilities, etc don't matter to me, and I suspect that's because they were all fairly similair. The one small detail that did catch my attention was the support staff in house. For example, some places have no residents/NP/hospitalist overnight, so you are essentially the resident and fellow. I think that can certainly have an impact on quality of life, and in general I have to admit I'm not psyched to be a resident for another 3 years.
I totally agree with Easily_sunburned, location, location, location. It was super important to me, so I only interviewed at places I could see myself living. I know I missed some great programs as a result, but that was a sacrifice I was more than willing to make for my overall happiness.
Those are just some of my thoughts! Good luck everyone. May seems soooo far away
