Hi folks, I have applied to PhD programs in iSchools for fall 2012 and have heard good news from them. I am now facing problems as which one to choose. Any one here facing the similar issue? Any one studying in these schools? What factors would you put in priority when you want to do your PhD and are looking for a research career in a top research university or a company like IBM, Microsoft, etc.? How important ranking is? Ranking of the program or ranking of the school in general? I would really appreciate your inputs!
