How does an employer interview a person with a disability?
An employer should interview a person with a disability the same way they interview other candidates. Procedures should not change when a disability is apparent or disclosed. Further, a hiring manager should avoid assumptions about the existence of a disability and its impact on job performance. He or she should feel free to ask questions about how each candidate will perform specific job tasks, taking care to ask the same questions of all applicants, not just those with disabilities.
