Amazon Software Development Engineer (SDE) I interview questions

I applied for SDE1 on the Amazon job portal. After few days, I got an exam link from Amazon. In the exam, there were 2 coding questions(DP, Greedy) and 2 descriptive questions in which we have to explain how we approached the above 2 questions and write about their time and space complexities. The interviewer was friendly and the overall experience was great.

First round was DSA + Resume. DSA question was based on Trees. Second round was DSA round and was based on arrays and Trees. Third round was a Bar-Raiser round.
