Generally speaking close friends tell each other their step scores, especially as time goes on. Unfortunately that also means that their friends tell their friends, and before you know it the whole schools knows. They also have match panels throughout the year, which almost always include Step 1/2 clinical grades AOA etc. I obviously can't tell you the top 20 step scores of my class in order, but I know countless step 1 scores from my friends in my class as well as those a few years above and one year below. Step scores aren't some big secret. But no, I definitely don't ever talk about that on the interview trail or anywhere outside of face to face with friends, that would be weird.
I will reiterate, 95% of the 250+ crowd are baller human beings and will make smart, compassionate, and quality doctors. You can be absolutely be smart and socially competent, they aren't mutually exclusive, don't buy into the lie that all smart people are socially inept robots and that you need BELOW a 250 to know how to talk to patients.
