I received an email for the HR department requesting an interview, in the email, it pertained information about who my interviewer would be, how long it would take and if the time went over it would end around this time; including the information about the interview. Which I thought was normal, however, when I had my interview the interviewer was extremely unprofessional. He treated me like a child since the beginning of the interview, used a site that wasn't secured, was inconsiderate of time, did not state any important information pertaining to the job ( I had to do some digging), and asked for personal information that I would have preferred to fill out on a secured site. I did receive the job offer but had to decline due to personal reasons, my interviewer asked me to clarify; I clarified and answered what felt like an appropriate answer without giving away specifics that would make me feel uncomfortable. I was shocked when his answer was that I said it for the millionth time... I only said it twice one of which was to answer his question to clarify.
