I have never had such a negative interview. There were two 30 minute interviews. The first was ok but the second interview gave me the immediate impression that they were shocked I was put before them for an interview.
At the end of the interview I asked “Do you have any concerns about my fit for the position I can try to address?”
One of the interviewers literally responded “Oh wow” - with a tone indicating she didn’t know where to start.
Obviously not a good fit for me but I hear great things about their reputation for quality work.
