Well, I am not quite sure about paticular area, actually I major in Telecommunication during my undergraduate study so my understanding and skills of computer science is quite lacking...
But I heard that for industry job seekers, algorithms and coding abilities are more important, regardless of what areas you study as a graudate student.
And for the Electrical Engineering field, I would say I may pursue the embedded system and MCU design and development. Maybe I should compare the prospects of these two areas in career development:
embedded system development vs. upper-layer application software development, which most CSer do after graduation?
