I had Angular front end interview set up. I am not sure whether it was a screening round or first round of technical interview. Interviewer kept on digging all the concepts and interview was very difficult. He wanted each and every code to be written. The interview went on for more than 1 and half hours. Later got the call, saying that there is client interview. The client was not at all satisfied with the answers. He kept on asking 'is there any other way to achieve' even after providing multiple solutions. Seems he was looking for exact solution in his mind. He was not even understanding few basic concept of shallow and deep copy. I had to explain him more than 5 times. Very unprofessional and time waste
