A shortage of IT skills in Ireland has prompted tech giants such as Microsoft and Google to collaborate in an effort to lure more IT workers to the country. Skills most in demand include software development, support and marketing. "Dublin has become one of the world's leading tech hubs. There are fantastic career opportunities for people with IT, business and multi-lingual skills, and it's one of the best cities in the world to live in," said John Dennehy, CEO of Zartis.
