Excellarate Senior Java Developer interview questions

I got the call from recruiter & had one round of technical discussion & though it was supposed to be virtual video round but neither the interviewer came on video nor expected me to switch on the video & we had normal 30 mins of discussion. Then in second round, not so professional person asked me to switch on video but not his video on. When I suggested that we both should be on video then he arrogantly left the meeting & HR started blaming over the audio.
