^^^ I agree with post #12. A couple of years ago, there was a delay in when mids who had recently graduated were able to start their next phase of training. Some were temporarily assigned to work in USNA admissions. Much like those 'what are my chances thread', there is really no point in trying to assign a specific meaning to those phone calls or attempting to correlate it to your h.s. resume. Someone's project may have been to contact those on a randomly generated list who had just attended NASS and complete a survey to capture feedback.
It is just as resonable to assume that someone generated a project for them during their time assigned there. We really have no way to know for sure.
Remember that many who eventually get an appointment, weren't selected to NASS for any number of reasons, so the one doesn't necessarily translate to the other.
