NHS interview questions in Truro

Two interviewers asked 6 questions. While I was talking they both scribbled on their notes so no eye contact. I could tell they had already interviewed someone they liked. It was very hurried and they made me wait 20 minutes in the waiting room beforehand. No one apologised nor told me why. I wish I had walked out and not bothered. I answered the questions well and have 15 years previous experience as a medical secretary.
