As a PD, I need concise, not flowery, wordy, overly descriptive CV's I want to see education, experience, awards, research and leadership. Beyond that is fluff. If someone puts "DDS Class President" then uses a paragraph to describe what the job was. I am out. I know what a Class President does, don't try to make it more than it is. I can read research, I don't need a paragraph description of your dental school project. The title will speak for its self. Lastly, don't tell me what you did on externships or during your internship. I know what those are and what is entailed.
Hope this helps. CONCISE! and whoever above said 1-2 pages max. Perfect, we need more of those voices on here.
