I agree with the comment below, specific skills will be different depending on what company. I came into programing and CS from concert Lighting 5 years ago. I started learning iOS however if I did it again I would learn something like Javascript/ html of Java first to get an understanding of the concepts. Check out Code Academy. Also I would get an idea of what kind of role your after and learn the relevant language. If you are interested in basic programming courses and have the time the Stanford courses (CS106A and CS106B) which are on iTunes U are good starting points. Hope that helps.
