What kind of information should a candidate avoid including in their resume?

Including unnecessary personal details in a resume can detract from a candidate's professional image and may raise privacy concerns. Resumes should focus on relevant qualifications, skills, and experiences that showcase a candidate's capacity to fulfill the job requirements. Personal information such as age, marital status, religion, or other demographic factors does not contribute to assessing a candidate's ability and can potentially lead to biases in the hiring process. By keeping the resume concise and relevant, candidates can ensure that employers focus on the most important aspects of their qualifications.
