It is used to keep record of all the CVs you send out. There is nothing worse than receiving a call from an employer stating that they received your CV and wish to interview you, and you have no idea what is about. You need to keep record, especially when you send many CVs to employers and react on advertisements. Record the transmitted date, destination, address, recommended by, the job specifications, observations and review for each CV you send out. It also helps you to follow up as well as thanking the person who recommended the employer or you. Keep it close to the telephone as this will help you identify what the call is about when an interviewer comes back to you.
