I don't know how this stuff works, but this definitely seems like an oversimplification. I'd imagine medical schools (in general-each is different) screen by numbers quickly, then try to recruit for an interview based on diverse experiences. Inevitably there will be some objectification of this like +2 for non-trad if positive experiences, +2 for student athlete, +3 if from a culture/race not highly represented in pool, From this, they ranks all candidates and invite candidates in waves. (Some like RFU/MCW small pool which seems different). If you've got high numbers, but poor involvement in other activities, you may not be picked. Also, I don't think all schools can be generalized in how they treat interviews. Some admittedly may see them as a formality while others (especially those with the MMI since they get a quantitative aspect) may weigh them as an objective matter in the process. N=1 here, but going into an MMI interview my friend and I both had very similar stats... I think i rocked it while he said he didn't like his, I got an acceptance two days later, he ended up wait listed.
