Kore.ai interview questions

Applied online, received a call from HR 1. HR was polite and gave an all round overview of the job description and about the company 2. First round: interview on core technical concepts about scaling, performance, load balancers, previous project details, databases. Interviewer was quite good and it was a pleasant discussion for about an hour 3. Second round was expected to be with the architect, was expecting a design interview but turned out to be another algorithmic interview much to my surprise. This time it was a panel interview (2) and only one interviewer was talking and the other one was silent for the whole duration of one hour The interviewer struggled to ask the questions right, probably because of bad communication skills. The questions itself did not make any sense. not one bit. Interviewer struggled to explain the questions. I was struggling to understand the questions. Over all it was a hot mess. During all this time the other interviewer kept silent. It was over google hangouts and both the interviewers did not turn on the camera and I had to awkwardly stare at the blank screen. Bad interviewer with such bad communication skills that you wouldn't be able to understand the question. I wonder if he's the architect, how could he communicate any details to the team This one hour of my life was a complete waste.
