To create your CV, choose a professional email (as firstname.lastname@gmail.com, but not as something that can be considered unprofessional). Provide a link, in case you have a LinkedIn profile, portfolio, or individual website on which you show your work or professional life. This may give additional information on your qualifications and achievements. The most typical errors that are made when filling this section are the failure to renew the contact data, having an amateurish email address, or sharing unwanted personal data with it, like your social security number or your date of birth.
