Amazon Software Engineer Internship interview questions

There were two pre-screening online assessments. The first one was fixing simple bugs in simple code (mostly off-by-one errors in loops) and answering 25-ish logic puzzles. The second was 2 coding problems involving binary trees and sorting packages.

The process took 4-5 weeks. There are 2 online assessment rounds followed by a telephonic round. Initial assessment consists of debugging and aptitude questions to be solved in 55 mins. The second round consists of 2 questions based on algorithms to be solved in 70 mins. The final round is a telephonic interview of 45 mins taken by a Sr. manager of AWS.
