You don’t sign off a CV. A CV details your work experience, skills, and educational background, and it doesn’t require a signature.
However, you do end your cover letter with a sign-off and signature.
Use:
- ‘Yours sincerely’ if you used a person’s name in the greeting
- ‘Yours faithfully’ if you used ‘Dear Sir/Madam’ or ‘To Whom It May Concern’
