i dont think the interviews are "token" because you have to bust your butt to get that 3.5 in the first place. basically at gtown the SMP people are looked at separately and differently than the rest of the application pool for gtown. thats why they interview them so late, and why they take so many of them. that being said, i saw alot of my very qualified friends get interviewed and then rejected by gtown while some butt kissers got in. its just like any application, its so iffy/luck of the draw it makes u want to break stuff. if u get that 3.5 they consider u able to be a med student, the rest is all the personal stuff from the interview that decides who they take.
another thing to consider is that dr.myers has done alot of work to spread the word about the SMP program and what its students have to do. no 3.0 = no degree. all the major 1st year classes except anatomy and biochem (SMP does a biochem type class though its grad. school level) several schools know about and hold an unofficial preference/consideration for SMP grads knowing what they have already done at gtown (drexel, USUHS, NYmed, albany, jefferson, tufts, and many more) and if you put in the work, the entire SMP staff will go out of their way to help you get into medical school. be it reccomendations, essay help, which schools to apply to, mock interviews, they are there all the time and the door is always open.
these are just my personal thoughts on gtown, and i chose to do the SMP because it was a great city, a renowned university, i got to compete DIRECTLY against a very competitive class of first year students, and i earned a masters in one year which i know some of the other programs dont do (2 years or just some certificate thingy)
