Virtual meet due to Covid. 6 hours, 5-1 hour meets with a one hour break. Lots of behavioral/technical questions. Overall the flow was easy, not that the questions were, but the flow was good. My biggest concern would be giving candidates enough time to ask questions and dig deeper on the Amazon time, felt that was limited.
One thing I liked is they were very efficient from start to finish. It was a great learning experience. No offer, but no complaints. I was fine spending prep time and the day doing it, it was a wonderful education.
