I would say averaging somewhere between 90-100 hrs/week is typical, depending on the service. Services like trauma might require you getting there around 5-5:30am and staying until sometime that evening (not including call days). Lighter services might be typically 12 hour days (for example 6am-6pm). I feel like most places encourage q4-q6 call, with the time you leave post-call varying program to program.
However, I'd like to read others' input as well.
