Amazon Software Developer Internship interview questions

Coding challenges were very enjoyable, but phone interview was nearly impossible. My interviewer didn't seem to be very engaged or interested, but such is life at such a large company.

I applied online in Jan 2019 and heard back from them in March. I received an email informing me that I've landed an interview with them in the next week. They had a few different groups of people asking me different types of question. The first part of the interview was testing me on my leadership principles, the next was algorithms, coding and data structures and the interview ended with problem solving and basic design. After a week or so i received an follow up emailing informing me that they wouldn't proceed with my interview process
