Amazon Intern interview questions

The interview process was really smooth. It had 3 Online Assessments and 1 Final Interview. OA 1 (Debugging Online Assessment): 7 easy debugging questions in Java, to be solved in 20 minutes. OA 2 (Coding Online Assessment): 2 coding questions to be solved in 70 minutes. OA 3 (Work Simulation Online Assessment): Questions related to Amazon's work culture, followed by 24 aptitude questions, to be solved in 30 minutes. After finishing the assessments, I have received an email saying I qualified for the final interview which was followed by an interview scheduling email in a few weeks. The final interview comprised of few behavioral questions, technical questions, and a coding problem.

1st was the coding round. 2 questions asked on Data Structures and Algorithms. 2nd Round was a technical Interview a lot of code optimization was asked and the whole interview was focused on real world problems. There were two more rounds.
