Photon API Architect interview questions

The interview was scheduled for 30 mins at 9 pm IST and the interviewer was late by 30 mins. The interviewer looks uninterested from the start. There was a moment where I was explaining my current project and the interviewer dropped headset and started talking to someone else behind him without even notifying me. This was very unprofessional. As far as I know I could answer all the questions asked related to architecture and microservices. I am not sure why it did not go through. Probably, the interviewer did not even hear what I answered.
