NHS interview questions

I was asked about how I have dealt with data breaches in my past roles (weird), even though that wasn’t a requirement in the job listing. Later found out that they have data breaches all the time and that I was probably rejected as I pointed out that that’s not a normal thing for an organisation to have. Questions were mostly rehashes of the same three questions about data management and personality. One of the interviewers tried pushing me to use my disability, which I had confidentially disclosed on the equality and diversity form, as an example of how I overcame a challenge in the past. Concerning how out of all places that would happen at an NHS mental health clinic.
