Greendale Veterinary Diagnostics interview questions

Despite not applying for the position, I was asked to interview by email but was given no job description. I was expecting to be told more about the role in the interview but instead was asked straightaway why I would be suited for this role. After I asked for more information about the role, was given a very brief and generic description of the role and then asked a bunch of patronising questions. The interview felt hostile and uncomfortable at times. Very unprofessional interviewers.
