Corky,LPN

Hi! So I'm a recent LPN and have been going on interviews and I am just having terrible experiences. I went on one yesterday (3/21) and the interviewer who was the Director of quality control asked me what I thought my typical day was like. I proceeded to answer with what the duties were that were listed when I applied to the job. (This job was for a day program for individuals with disabilities) When I said that I would assist with first aid for staff their response was "ha! No definitely not" I was so confused bc it listed it on their job duties! Then later during the interview I had said how I was really organized and that I actually love data entry and making med sheets and he laughed again and said wow you're a weirdo! I could not believe it. I continued with the interview and he said he would follow up next week. However, I absolutely do not want to work there anymore. Part of me is so upset about his unprofessionalism that I want to email their HR department and just let them know that I no longer wish to be considered for the position. Is that a bad thing to do?
