In my case first round was good and interviewer was also kind and professional. 2nd round went well, interviewer was satisfied and offered the role. But few things disappointed me of 2nd round interviewer. In second round interviewer seemed unprofessional, between interview he stopped me 3–4 times for reasons like clarifying about candidacy, phone calls etc, yawning, asked me to repeat answers 3–4 times not because he couldn’t hear or network issue but he was operating phone while interviewing. He asked me to swith on my camera but he didn’t showed up himself. If anyone who is interviewing please be professional and kind.
Over all experience was Average. Result I was offered role.
