What do you think? Any anecdotal evidence? Or is it more about who you meet while you're in residency--in that same city?
There is self-selection at some of the top-tier places for people who desire academic careers in sub-specialized fields, necessitating fellowships. More than half of my class in my program also has PhDs, so there is also a huge research drive. Hence, most people here would never even consider getting a job right out of residency. That isn't to say that they couldn't get one if they wanted to, but it just isn't the primary focus.
If you aren't interested in subspecialization or research, you might be better served going to a program in an area where you would be interested in working afterward. I'm not convinced that the clinical instruction itself is really that much better at a top-tier program than anywhere else. We see more crazy presentations and rare disease, and I can get you a portable head CT, but whatever. The relationships you build during residency with faculty and administration are important for networking. If you are interested in private practice, then starting to build that network during residency would certainly help when it comes time to get a real job.
How do you define "better job"? Better than what?
