The interviewer used a lot of jargon that I thought was unnecessary but he was generally helpful. Asked a lot of SQL questions that weren't too bad mostly. Some more advanced SQL questions as well.

Mix of cultural fit and technical interviews spanning 3 weeks. All interviews were virtual. One HR person was primary contact for duration of interview process. Amazon provided good tools for managing the interview scheduling and process virtually. I was provided with good background information on Amazon, its culture, and how to prepare for the interviews.
