A year ago my company hired two young developers straight out of university and we've been training them on-the-job ever since. They are pretty well up-to-speed now, but it did take a full year to get them to a point where they are more gain than drain on the rest of us. I guess that's why not many companies do it, since it has been fairly expensive in salary to the new guys + productivity loss for the rest of the department. It's great now, a year later, though.
