Do the majority of successful applicants send letters of interest, updates, call the admissions office of the schools they are interested in/waitlisted at? I have not done any of that this cycle and have seen many people on SDN regularly emailing/calling admissions and staying in close communication with schools and then getting an interview/acceptance from them. Is it common to be accepted without doing any of that, or will schools I am interested in interviewing at/am waitlisted at take silence as disinterest and choose someone with more "expressed interest"? Thank you to all who can help clarify this. Just trying to figure out if this is something I ought to be doing.
