According to the Americans with Disabilities Act (ADA), a person with a disability is not required to disclose their disability to an employer at any point in the hiring process, unless they need a reasonable accommodation to participate in the application process or to perform the essential functions of the job1. Therefore, Tom is not required to disclose his epilepsy to his employer before, during, or after the interview, unless he needs an accommodation such as flexible work hours, breaks, or a quiet work environment. If he does need an accommodation, he should disclose his disability before the accommodation is requested, and provide relevant documentation to support hisrequest2.
