Amazon Support Engineer interview questions

I was hired through an internal job posting, one of my previous colleague was working in that team and she referred me, with in a weeks time I got a call from manager for an interview, I had scheduled and had 2 rounds of interview one with tead lead in the position of support engineer IV where questions were about networking, AWS concepts and linux, was not too difficult. Later, I moved to next round where HR manager asked me about Amazon leadership principles and how I was I able to implement or adapt in my work, followed by some situational based questions, within 3-4 days I got a confirmation from manager that I am in.
