Amazon Senior Support Engineer interview questions

After 20 days of process, I got rejected mail as per my interview experience the team is good but the interview questions and related experience not matched in few rounds. First Technical round: Interviewed in client application asked pure UNIX , JAVA and few networking, file and text processing queries with UNIX . Second Technical round: Interviewed by onsite team mostly focused on debugging and testing of an Amazon application and very few queries on technical aspects. Most of the time tested with Leadership principals. Third round: Manager round focused on Management and Team lead aspect queries like what aspects will you check in company profile, while giving project to other companies and you are a team lead for the company who got project and what measures will ask for project smooth run.
