It's more of how well everything fits into their narrative. For example, one student was telling me about how they participated in all these diversity outreach programs and the impact they were trying to make during their college years. Their narrative was about increasing diversity in medicine and it all made sense and fit together very well. I still remember these things about that student. But another student on that same day was telling me about how much diversity means to them and how they want to participate in all these outreach programs in med school but it wasn't consistent with their narrative at all. They had zero experience in diversity outreach in the past. Two very different ratings.
At the end of the day, if you're weak in one area, you're weak in that area. You have to have some experiences to work with and then it's all up to how you play your cards - otherwise the interview is going to be very short and boring if you don't have anything to talk from.
