Failed an interviewee because they wouldn't shut up about LLMs at the end of the interview

Last week was interviewing a candidate who was very borderline. Then as I was trying to end the interview and let the candidate ask questions about our company, they insisted on talking about how they could use LLMs to help the regression problem we were discussing. It made no sense. This is essentially what tipped them from a soft thumbs up to a soft thumbs down.
