In a job interview, there is information asymmetry between the interviewer and the candidate. The candidate inherently knows more about their own background and qualifications than the interviewer does. To address this, the interviewer can ask questions to learn more about the candidate's work history, education, skills, and goals. They can also make an assessment based on basic information provided, like academic credentials. If a candidate deliberately withholds important details, the interviewer may choose not to hire them. However, the interviewer should not immediately reject a candidate if they are missing some information, as there could be a reasonable explanation.
