One of the graduation requirements for my degree is to complete 3 co-op rotations (essentially full time paid internships that each last one semester), with an optional 4th. As a result, when I graduate I'll have worked for one company in my field for 2-3 calendar years even though I wasn't working the entire time. When I list this on a resume, should I make a note that it was non-continuous, or just list the years I worked there?
In case it's relevant, my field is computer programming
