I am not yet working on postdoc applications but am only about one year away. Given that internship applications are already submitted, this question is more relevant to postdoc as well as any other reasons I may need to submit my CV in the interim.
My peer-reviewing experience to-date has been listed under the heading Service to Profession. However, I have also accumulated non-journal reviewer experiences such as reviewing grant proposals, research awards, and conference abstract submissions. My assumption is that these latter experiences will eventually be unnecessary on my CV as I move along my training trajectory (at worst, seem like padding), but am wondering how to separate these types of 'reviews' or experiences to best highlight what seems most important - reviewing for journals. For example, is my current section heading too broad, should I create subheadings, create separate headings altogether, or eliminate some of these experiences from the CV? Any thoughts or insight will be appreciated!
