PDSA interview questions

The questions were fairly standard and the interviewers were fine at first but as the interview went on it was clear they were disinterested. There was some negative body language given off and one even huffed at one point while I was answering a question. There were a few unwelcomed comments made and when I was explaining my experience and giving an example they commented "and you did that by yourself did you" in a tone like they didn't believe me. Overall I was glad when the interview was over.
