From a neutral point of view, I believe that the majority of the people might use it interchangeably but it is still interesting to know that there might be this distinctive difference between CVs and Resumes.

On a side note, personally i feel CV should be kept short and sweet with important key words highlighting ur area of expertise of about 1-2 pages?

Some may debate that 1 pages is the standard but i think its ok to have 2 pages. While the 1st page contains all the necessary important attractive details that will appeal to the reader, making them wana flip to the 2nd page to read more?

Of coz if ur CV is 1 page sufficient, by all means stick to that.
