Office for National Statistics interview questions

I applied online and was asked to complete an online skills test. I was then invited to complete an online group Dissemination Test followed by an interview of competence and behavioral questions as well as a presentation on the data from the dissemination test. All of this was done virtually. I found the majority of the interviewers to be quite rude and impatient, not just to me but to the other candidates in the dissemination test also. The tone of interview really downgraded my experience with interviewers appearing condescending and pushy, with one rolling her eyes multiple times throughout to my answers and follow up questions. I struggled with one question and openly said I was unsure to which the interviewer repeatedly asked me the question and refused to move forwards until I gave a satisfactory/made up answer. Many of the questions asked appeared to repeat themselves, however I was not allowed to use the same example/experience for more than one question throughout.
