Which of the following can be considered a reflection of one's work experience?

A resume can be considered a reflection of one's work experience because it is specifically designed to summarize an individual’s professional history, education, skills, and accomplishments. Resumes serve as a formal document that potential employers review to assess qualifications for positions. It highlights job responsibilities, achievements, and durations of previous employment, which provides a clear picture of how a candidate's past work experiences align with the requirements of a potential job.

Other choices, while they may provide insights into a person’s skills or interests, do not serve the same formal purpose. A social media profile might reflect a person's personality or social connections but is not typically a structured account of professional experience. A personal diary generally contains private reflections and does not serve as a professional document. Pet behavior does not relate to work experience and is unrelated to employment qualifications.
