I mean how can an LOI hurt you tho? It can only help you. I see NO reason for a program to interview someone without the intention of atleast ranking them, maybe your LOI can help you get ranked a bit higher. This story sounds untrue, and if true, what a waste a time for both the person and the program. No program is worth wasting your time even if it's a soo called top program. Programs have a limited number of interviews and if they are just simply interviewing DO's for drive by looks they are wasting a lot of time. The Reddit poster is overthinking it, they should rank them #1 if they want, irregardless of anything since the match favors the applicant not the program. Unless the program straight up says we won't rank you. This is different if the person did an away there, didn't get an interview and then they pretty much begged for a courtesy interview in which case maybe the program will DNR them, but your case and the Reddit post are not that..
