please give me some advise about how wirte a resume
There is a difference between a curriculum vitae (which is a full accounting of one's work history) and a resume (which is a shortened version, highlighting specific jobs).
During a phone conversation with a lady in Canada I mentioned 'C.V', and she didn't know what I was talking about. So I said 'Curriculum Vitae'. Same response. I eventually said 'Resume', and at that point we understood each other. I was honestly gobsmacked!
cranura is right. Its completly two different things. I too have had people not know what I was talking about when I said CV.
