Look at what courses you would take for each major and what you want to learn too.
For example, I'm going to RPI, so here is what EE and CS would take at RPI:

For an idea from the workforce, I have no clue, but an idea from someone who is a year ahead of you and going through a similar process to find out what I want to major in, I think it is a good idea to keep your options open. You do not need to decide now. I haven't decided yet, and won't until I have to choose classes for second semester. Its good that you know what you want to do, although even that may change some, who knows. As for me, I am taking the required first semester courses for Electrical, Mechanical, and Aerospace Engineering as well as Physics first semester, so that I have more time to decide which one(s) I like best.
