Design facebook msg app

The interviewer was not interested in the entire interview process. I tried interacting with him but it was a failed attempt. He did not turn on his video, did not give his introduction or asked mine either. Copy pasted the question & asked to solve. [This was a clear Red flag for the company, they are unprofessionals].
