Amazon Sr. Software Engineer interview questions

I was contacted by a recruiter via my LinkedIn profile. He requested a resume, and then within a day asked to schedule a phone screen. The phone screen was a little choppy because they were using a new tool similar to codepen that allowed your code to be evaluated while on the call. The review was pleasant enough, and--in spite of not being prepared for the low-level java implementation questions--I made it to an on-site. The on-site is where my experience diverged from expectation. Having heard that you are interviewed for multiple roles by a range of people, I was fully prepared and excited for that. I my case, there was only one role, and all but one of the interviewers were from that team. Since none of them were senior engineers, they had a hard time engaging my questions and thought processes, which made the conversations rather awkward and stifling. By the time I met with the engineers from a different team, I was a bit off balance, and felt like I didn't shine. The last interview was with the person who would have supervised me, and we both expressed that it didn't seem like a fit right now.
