I think it was actually easier to get into medical school because of my major. For some silly reason, medical schools want people to be well-rounded (only to make them one-dimensional later). The admissions committee also like to brag to each other (in other schools) about how great and unique their class is. "Hey we have a former Olympic gymnast!" "Oh yeah well we have a former violinist from Julliard!" ...that sort of thing.
Philosophy majors traditionally had the highest acceptance rate to medical school. Nursing majors had the worst. Biology majors were one of the lowest also. Medical schools don't want boring cookie cutter students. Also, conventional wisdom says majoring in what you're most interested in helps people do better overall, for what it's worth. I don't really believe that btw... you can be interested in engineering but chances are, your grades will suck more in engineering than sociology.
The MCAT was probably the second hardest test I ever took. The hardest was the USMLE Step 1, which students take after the 2nd year of medical school. I don't think it was difficult because I was a philosophy major per se. I minored in a biological science and had all the pre-requisite courses. I think the test is just difficult for most people.
I think I was one of those memorize-everything premeds. Not because that's my learning style, but because I was forced to be that way. I'm not a chemistry major, and I don't find organic chemistry very interesting, yet it is required, so I just did what I had to do to jump through that hoop. I think the environment and situation someone is in has a big impact on how they behave. Medical school will force you to memorize a lot and also require you to be somewhat social. Sometimes there just isn't an underlying concept to things you learn in medical school, or you just don't have time to figure it out. Sometimes the quickest and least painful thing to do is blindly memorize. Obviously I don't have that approach to everything - I can't just memorize stuff in philosophy.
As far as what you specialize in, I think pathology might be a good fit. I personally hate pathology, and I didn't want to just stare at pink dots everyday. There are various motivations why people choose this or that, but I chose surgery because I wanted to balance myself with something more practical, with tangible results. I didn't want to just be a head in the clouds philosopher thinking about stuff that no one else cares about. I mean I enjoy that from time to time but I wanted something more in life than that. I find psych or neuro intellectually stimulating, but stimulating my intellect was not what I primarily wanted out of medicine (or else I probably would have gone to graduate school in philosophy). I can find stimulation from things I learn on my own, outside of the hospital. Others might not care about that and be perfectly happy with pathology, psychiatry, or neurology. Like I said, I try to avoid fitting neatly into any category, and I don't let my Myers-Briggs type define me. (Although it comes pretty close

)
