Often the terms Resume and CV are interchangeable and thought to be the same thing; however, in actuality, there are differences for each document.
A CV (Curriculum Vitae) is a longer, more in depth document that details the whole course of your career and academic history. This would include a complete description of your entire background, education, achievements, publications, awards, certificates, conferences, research, and personal information. There is usually no restriction to the length of a CV. In most cases, a CV is used primarily for academic purposes, such as applying for a position as a Professor at a University, a PhD, or Academic Research.
On the other hand, a Resume is a brief snapshot of your career credentials for a specific job. It is a document presenting key facts about your professional experience, educational background, and skills, in a consolidated format , that will be of unique interest to the recruiter. The resume will also optimize keyword usage to attract the ATS scanner as well as the recruiter.
The CV and Resume differ in length, purpose, and the information that is included. The resume is a brief marketing tool customized for a specific job. The CV is longer and more comprehensive, mostly used for academic purposes and is generally used universally.
