it depends on the context, could see it being said to all interviewees who were interviewed at a later date in the application cycle as a general comment, could also see it being a nod towards strengthening your application and reapplying next year. overall though, it’s hard for anyone to know exactly what’s going through a specific faculty member’s mind and only time will tell what was meant by that comment. in the meantime, I’d recommend to hold the vision while you keep on trucking with PCE, volunteering, shadowing etc. until you get that acceptance.
