While a CV provides a detailed summary of your professional experience and qualifications, it doesn't reveal much about your personality, values, or interests. Interviewers often ask you to share something about yourself that is not found on your CV because they want to gain a deeper understanding of who you are as a person. Interviewers hope to learn more about your character, motivations, and whether you would be a good fit for the company culture by asking this question. It also lets you showcase your unique qualities to stand out from other applicants.
