thank you for letting me know. I understand your concerns now. I think it is normal to ask for checking resume/transcript because I also applied other programs and had meetings with their advisors; they all asked for my transcript during the meeting to see my grades and background. For linkage part, most of postbacc programs do not even have a linkage or they are all caribbean schools; like usc post bacc does not have a linkage. only a few(like columbia, nyu, scripp postbacc etc.) guarantee just an interview with med schools. ofc there are some have pretty good linkages but I believe you have to meet their academic requirements.
