I applied online. I interviewed at Amazon in Feb 2021
Interview
3 Online Assessments, First was 7-debugging questions in 20 minutes, the second was 2 Leetcode-style questions in about 50 minutes (plus/minus) and the third was a 2-hour long simulation where you reacted to problems, emails, and code reviews as if you were an actual software developer at Amazon.
After all that, I met with an Amazon employee virtually and I was asked some technical questions and some questions relating to their Leadership Principles.
Interview questions [1]
Question 1
They asked me about how I had once showed *insert Amazon Leadership Principle*.
Technical Question was a Leetcode Medium related to BSTs.
Standard LC mediums, nothing too crazy. Interviewer was pretty chill and was helpful in pointing me in the right direction when I needed as well. Only thing I would probably change was to study more on graph problems before hand.

Question 1
You are given an 0-indexed integer array weights, where weights[i] represents the weight of the i-th marble, and an integer k.
Your task is to divide the marbles into k bags such that:
No bag is empty.
Each bag must contain marbles from a contiguous range of indices. That is, if a bag includes marbles at indices i and j, then all marbles with indices between i and j (inclusive) must also be included in that same bag.
The cost of a bag that includes marbles from index i to j (inclusive) is defined as weights[i] + weights[j].
The total score of a distribution is the sum of the costs of all k bags.
Return the difference between the maximum and minimum possible scores among all valid distributions.
Applied online and received an Online Assessment. It consisted of two LeetCode-style coding problems with a time limit . The process was straightforward and fully automated with no human interaction at this stage.

Question 1
Solve a coding problem involving array manipulation under a timed online assessment
There were 2 rounds- one DSA round and one HR round.
In the first round they asked me a DP + trees question which was of medium to hard difficulty.
In the second round the interviewer asked me about my resume, my projects, some computer fundamental questions.
