Agree with DrMom above. The hours, workload and expectations varied greatly with each individual specialty...and even talking with some of my friends I found that the workload among the same specialty varied from hospital to hospital.
Some of your months with be all inpatient, some all outpatient and some mixed.
Some you will be running all over the hospital and others you may never leave one area of the floor (ICU perhaps).
Be prepared for long hours and long workweeks. Afterall, as an intern you will be expected to function at your fullest potential working on no sleep for >24 hours.
Why not get used to it early on?
