Nagarro SSE- Development interview questions

Some old aged person took my interview who was very bossy with so much of background noise ,I was asked to turn on the camera ,but he dint which was ackward . he was taking 10 min pause to ask a question , and asked same question multiple times repeatedly , may be forgot that he asked it ,I even pointed him out that you just asked this 5 min before , No professionalism , children are playing in background, wife is scolding and this old man is taking my interview with camera shut down and taking off his frustration on me by making his voice loud and being bossy
