Generally, employers make preemployment inquiries to find out whether an applicant has the skills, experience, and education to perform the duties of the job in question. To avoid discrimination claims, employers should not ask job applicants about characteristics that are unrelated to job performance, such as age, religion, citizenship status, disabilities, or union membership. Employers should use accurate job descriptions that list duties and responsibilities for guidance on job-related inquiries. Preemployment inquiries may include questions about previous work experience, job-related education and training, relevant personal characteristics, job-related military service, and authorization to work in the United States.
