That's a different known problem and it tends to be present in some people from day one (most meds schools try to balance this out in various ways). Different personalities enter medicine. Differential diagnostic skills are fairly standardardized in process, but are like any skill that should improve over time.

But one's ability to interact personably with other humans is entirely contextual, depending on the provider, patient, situation, branch of medicine, and even combination of those things. We all know at least one who lacks many social skills. But that's probably true in most professions and isn't necessarily a product of any procedure or methodology.
