"Anesthesiologist interships" are typically "general internships",
during the 1st. year after medical school,
and before (3) years of more specialized anesthesiology residency.
During an "anethesiologist intership", a medical school graduate,
under the direction and supervision of other medical doctors & residents,
receives the initial training necessary for the specialization of anesthesiology.
