It may be that the interviewer has already decided to take a pass and out of politeness passes the remaining time talking about everything but you. The truth about interviewing is that most initial interviews only last about five minutes. Oh, sure, the actual interview always takes longer than that. Sometimes even an hour. But the interview is usually over in five minutes or less.
Recoveries do happen.
But they are very rare. In that first five minutes of the interview, I will have noted many critical aspects. Your personal presence. Your eye contact. And, most importantly, your personality.
