One of my worst interview experiences was when I had a panel interview with three people. I felt confident during the interview and believed I had answered most of the questions satisfactorily. They even informed me that I would receive a call either on the same day or the next day for the next round. However, to my disappointment, I received a rejection instead. The reason they provided was that I lacked experience in cloud infrastructure. I have more than 6 years of experience into cloud services and have answered most of the questions asked by 3 panel members.. It was disheartening to receive such feedback after feeling positive about the interview process. I would suggest don't waste time and start recording interviews and start taking feedback from the candidates..
