It’s at this point that I would end the interview and let them know it doesn’t feel like it would be a good fit.
Compare to a recent interview with the world's best employer (tm): the interviewer was young, was upset that my solution wasn't written in Java (???), and when I described my experience I talked about dashboards and he didn't know what that was. I described it as charts and he didn't know what that was. I described it as graphs and he also didn't know what that was.
