Which of the two terms − "student employee" and "working student" − is more accurate and more common (in American English) when referring to a student who works for a salary at a private company (not university) alongside their studies? And is there any difference in the meaning?
A Google search I did before posting the question showed similar, high result counts (400-500k) for both terms. I also found both terms in dictionaries. This is part of why I am not sure which one is more commonly used.
