In our shop they have similar normal daytime hours, maybe a little more chill because they have downtime on procedure days. Usually 1 day of clinic per week. Depending on the amount of NIRs in the call pool they will be on call q2-q5 or so. Usually on the lower side. Some do diagnostics as well, some are purely interventional but split between LP/spine and angio days. Depending on how busy their practice is and how much elective stuff they do (aneurysms, MMA embolization, kyphoplasties, stenting etc) things can vary.
