As an IMG, my only pathway to a full surgical program was doing a prelim beforehand. Now there are many factors to contemplate when deciding how to rank your prelim programs. However, it will come down to this: The purpose of the prelim is to make way for a full program. Resident happiness? Scutwork? Big name? It all doesn't matter. It all comes down to where the program's prelims have ended up going (or not). It's only one year. You can be unhappy for a year, you can push patients for a year, and you can tolerate psychotic attendings for a year if it meant you have a higher chance at ending at a advanced surgical program after said year.
For me, I had two strong "big name" programs on my list. One was an Ivy League where they didn't bother give the prelim interviewees a presentation of the program, had visibly unhappy residents who complained about how they wished they had better operative skills, and attendings that were relatively difficult to deal with (the PD was super friendly though). The other program offered significantly better clinical training, better prelim treatment, less scut work, better overall facilities, and the residents were incomparably happier.
Tell you what. This all didn't matter; it's just one year. It came down to this: The Ivy League program had a much lower rate of prelims ending up in advanced positions, they didn't even want to divulge this information in the program overview. The other program had an almost 100% rate of prelims ending up in advanced surgical positions over the past 6 years. I ranked them first, even though coming from an Ivy League theoretically makes it easier to land advanced positions, and even though all my friends lived there and I knew the hospital better. But the only number that counted -prelim advancement- was not in its favor. Time will tell if I made the right decision.
