From the interviewer side, I would keep with the scheduled items for the interview. Then give the answer next day or whenever the results should be communicated.

From the interviewee side, stop the interview conversation and state my thoughts.

It happened to me that the recruiter asked if "I worked with Linux", I said yes as a Java Developer and moved to the next step. The day of the interview, after some questions I just wanted to die, they were questions about developing Linux itself at low level C. After answering only 1 or 2 questions. I stopped and told the interviewer the confusion.
