Vetting is the process of thoroughly investigating a person or thing to ensure that they are suitable for a certain purpose. It is commonly used in the hiring process to ensure that potential employees have the necessary qualifications and experience for the job. It can also be used to evaluate the quality of products or services before they are released to the public. The term 'VET' is derived from the Latin word 'vetus, ' which means 'OLD' or 'ANCIENT.'
