When I look at resumes and talk to candidates, seeing that they don't at least read about programming outside isn't an automatic no-go but as natch says, it's a red flag. I've worked with people who have no interest in programming, they just do it because it's what they do and they need a paycheck. Not programming or showing an interest outside of work is an indicator of this kind of person to me. Of course it's not 100% but it leads me to ask other questions to make sure they will want to learn. That said, there are plenty of corporate places that are perfectly fine with this kind of person, I just don't work at those places anymore.
