After reading through all (yes, all) questions in the cv tag, I have a thought that CVs for applying to a position of a university are different to CVs for applying to a fellowship. When applying to a position of a university, the quality of the CV is define by your papers, research experiences, education, etc. While when applying to a fellowship, a good CV is the one can show your leadership, volunteering jobs, etc. Yes, there are some overlapped sections, but these two are not the same. Are CVs for applying to universities different to applying to fellowships?
Unlike a resume, the contents of your CV should typically be comprehensive and complete, including both research experience and service. You might want to reshuffle the positions of sections within the CV for a target where you want to emphasize one aspect vs. another, but the content should be no different.
