It depends on what you want. Are you talking about hanging around your own department for a few months or a year after graduation in order to get your feet wet and see what you want to do next? A lot of departments will make room for that. A big X-factor, of course, is that clinical volume (eh hem, revenue) is way down, even at academic centers right now. Trying to get hired to a career academic position, though, is a different beast. No, it's not like in other, more academic, specialties where you have to come in with a K grant, pay for your own time, build a program, and demonstrate potential for scientific independence. But programs generally want someone who comes with something, be it sub-specialty training in something they care about, a burgeoning research program, or some demonstrated leadership abilities. There's a range of academic programs, of course, but at big places, the bar is higher. Right now, they aren't short on labor, so you'd have to have something beyond the ability to hump cases.
