Ask structured questions that will require some thought on the part of the candidate. Listen carefully to the candidate's answers. If they do not provide you with specific results, probe until they do. Explain the selection process to the candidate. Most of these subjects relate directly to federal and state employment laws.
Legislation covering equal employment opportunity is extensive and complex.
Check not only federal laws, but also your own state's laws and guidelines. In some cases, credit history may be considered job-related, but proceed with extreme caution. Avoid any language or behavior that may be found inappropriate by the candidate. Attendance records at a previous employer may be discussed in most situations as long as you don't refer to illness or disability. Check the law or consult with an attorney before moving forward.
