Amazon Business Analyst interview questions

interview scheduled but none joined. I try to reach out to HR but still no response. interview was rescheduled twice both time i faced same issue. it would be better if they respond/confirm earlier in case of last minute changes.

Very straightforward. HR was very helpful right from the start to end. Had a prep call right before the loop. The loop was 4 rounds for 45 mins each which extended to 1 hour
