Not sure how serious you're being but the answer is yes, surgeons seeking to change from hospital A to hospital B have interviews where a surgeon from hospital B will visit hospital A to supervise a surgery or other operation. Depending on how critical the position it may even be a partner from one hospital doing the supervision. In fact nowadays the supervision can be done remotely.
Furthermore surgeons are required to maintain their accreditation by earning credits on a yearly basis through continuing education and/or training and they do so on their own time.
These guys don't mess around and if you think surgeons get hired because of their wonderful personality then you sorely underestimate the medical profession (and overestimate their personality ;P ). It's incredibly competitive, demanding, and prestigious in almost every sense imaginable.
