Though I was told that the position is backend oriented all of the interview was focused on React code. I told the interviewer that I didn't touch frontend for at least 4 years, but he insisted to get on with it. In the end of the interview I was told that he was looking for someone to handle React code and that I didn't pass. It contradicts the so called backend orientation of the position. I was really not prepared for this kind of interview and felt chitted and insulted.
