The important difference between a CV and a Resume
It is well known that when you apply for a job, you have to present the prospective employer with some personal information. This info will usually be in paper or email form or even an online profile, and will contain your personal information, education, work experience and your hobbies or interests. Some people call this a CV and others use the term a Resume. Job seekers are often confused about the difference between a CV and a Resume to the point where they use the two terms interchangeably and might even think its six of one or half a dozen of the other.

Whilst the two documents are the same in principle and used for the same purpose – securing a job, there are four defining differences between them.
Origin
CV is the abbreviation for Curriculum Vitae, derived from Latin and literally mean “course of life”
Resume stems from the French word which means summary. In this explanation lays our next difference:
Length.
The resume is a lot more condense and everything is jam packed into a one page summary. It is more of a brief summary where as a CV is more descriptive and can be between one and three pages long depending on your work experiences and education. A CV is a lot more detailed than a Resume.
Layout.
A resume is tailored for each individual application and is adapted each time it is written without any certain chronological order. The basic content is your personal contact details, your education and your work experience.
A CV follows a well laid out, chronological history of your life and contains a lot more information than its sibling the resume. Whilst the acceptable standard is a standing document, candidates who take their job hunting serious, will put the extra effort into a tailor made CV targeting the job that they are applying for. It is noted that in France applicants tend to include an ID type photograph as part of their CV.
Demographical use.
As a rule of thumb, people from Europe including Germany, (Lebenslauf) UK, Ireland, New Zealand and South Africa use a CV. Middle East and Asia also follow the route of using a Curriculum Vitae.
People in America and Canada use a Resume.
Australia and India are a little bit confused and would use either.
It is a good idea to have both at hand and to make sure your documents are well written and up to date. The best advice is to have a professionally written target CV for the job you are applying for to make sure you stand out in the crowd.
