The interviewer seemed very biased and disinterested in the conversation. This was one of the worst experience i had. I normally don't give feedback for the interviews but this time i am giving as i feel the interviewer was behaving bit bossy also the question were little orthodox like reverse integer then float and then next palindrome number. I feel this is not the way one should be judging a candidate having 8+ years of experience. I told all the answers and also wrote the code but still negative feedback from your side that makes me think that the interviewer was not interviewing to take candidate.
