In most countries, a resume is exactly the same thing as a CV. The two are really only distinguished in the USA.
In the USA a resume is a more condensed version of a CV. Furthermore, it's only people in academia in the USA that write CVs, most other people only need a resume.
One or two pages is recommended for a resume (or CV).
My personal preference is to see resumes/CVs of one page.
Why is one page better?
Most people nowadays have a very short attention span. If you give them a long resume/CV, they very likely won't read it properly, they will skim over it.
Even if your resume/CV is two pages, get the most important information onto the first side because it is more than likely that it will get the most attention.
These should be two or three pages in length. They are much more detailed in nature as such, you can't fit it all onto one side.
I created my investment banking blog in 2012 as soon as I resigned from i-banking & published my book, To Become An Investment Banker.
