Got reached out from recruiter. Didn't apply from anywhere.

Online Assessment: (2 to 2.5 hr)
2 Coding questions
Time - 90min

1. 1 Medium question based on strings. Didn't find anywhere.
2. https://leetcode.com/discuss/interview-question/2074062/Amazon-Shipment-Imbalance-or-SDE2-or-OA

Next 30-60min
Work Simulation – work through software development decisions faced by SDEs at Amazon, Design choice questions, etc.
Work Style Surveys – 2 surveys - answer questions about how you approach software engineering work and your approach to work in general.

Onsite Interviews:
Coding: (60min)
2 Leadership principles - Interviewer is most likely to dive little deep. So, be careful about the situations and outcomes that you prepared for.
discussion went on for 20min.

1. easy/medium question - similar to "Minimum cost to merge all elements of List"
2. medium/hard binary search on range question - similar concept of https://leetcode.com/problems/split-array-largest-sum/description/
   Started with DP solution with memo. Ended up with binary search.
3. easy question on graph - direct application of topological sort

One thing i have observed with FAANG companies is that direct questions were not asked. Instead a small story is plotted, then you have to figure out how to solve & what data structure to use.

i was able to solve all questions in the next 30mins. Was asked to write code on paper along with Space and Time complexity. Only approach discussed for 3rd question.

Design Round 1: (60 mins)
Again, 2 leadership principles for around 20mins.

Design a File download system.
somewhat similar to https://leetcode.com/discuss/interview-question/system-design/1071562/Design-a-File-Download-Application-System

Bar raiser: (60 mins)
2-3 leadership principles. Went on for long time around 35-40 mins.
Add two numbers represented by linked list. lists can be different sizes. Was asked to write complete working code after iterating from brute force to optimal solution.
Later, problem was extended to include negative numbers. Just discussed the solution, ran out of time for coding.

Verdict: Selected. Got offer letter within 4-5 days.
TC - 72 for 1st year. Didn't negotiate.
