This is EXACTLY what a certain state agency here in California did to my wife. They advertised this wonderful job opening for someone to help them implement/operate a new system the state is mandating they use. At the "interview" they picked her brain for two hours. And they hired nobody, of course.
I worked at one company where the Director of IT said blatantly that if you're not the type to learn new technologies on your own time, we don't need you. I asked about the obvious needs for conferences and the benefits of learning new technologies from the people that actually developed it, and he said, "Save up!"
