It is not legal for anyone to ask questions that may be used to discriminate against you on the basis of your disability.
Generally, people do not have to talk about their disability or how it affects them when they are applying for jobs. Disability, symptoms of disability, or what medical treatment you are receiving is private and sensitive information. It is up to you whether you wish to share this information or not.
However it becomes tricky when disclosure is required for employment.
If you are applying for a job, your prospective employers may require a medical assessment. However, they cannot discriminate against you with the information that comes from the medical assessment.
An employer is prohibited from refusing to employ a person based on a disability where it is not relevant to the inherent requirements of the job.
