It depends on the field. Electrical engineers in my area make a lot in internships, make a lot in full-time roles, and get so many offers that they can be picky about what they want to take. It also depends on the company. The bigger the company the higher the salary. However, to get to a place where you can make a lot in internships and be picky about roles, you have to work your butt off. This includes free or low-paying jobs to get experience, not having time for anything but work and school, etc. But if you do all that in good timing and while you’re in school you can move up pretty quickly with good internships and a good full-time role.
