You completed five rounds of LeetCode-style technical interviews. Each round featured average-level coding questions. Although it took some time, you managed to solve all of them.
Here’s a closer look at what this process involved:
The questions tested common data structures and algorithms, such as arrays, strings, trees, and sorting.
Each problem required a clear understanding of the problem statement and constraints.
You had to write code that was both correct and efficient.
Time pressure was present but manageable, requiring you to balance speed and accuracy.

Question 1
Two Sum
Longest Substring Without Repeating Characters
Merge Intervals
Binary Tree Inorder Traversal
Product of Array Except Self
Maximum Subarray
I applied through a recruiter. I interviewed at Amazon
Interview
The interview process started with an initial recruiter screening, followed by technical interview rounds. The technical interviews focused on data structures, algorithms, problem-solving, and discussing my approach clearly. The interviewers also asked behavioral questions related to teamwork, challenges, and past projects. Overall, the process was structured and professional.

Question 1
Given a binary tree, how would you find the lowest common ancestor of two nodes if each node also has a parent pointer?
I received an Online Assessment (OA) invitation from Amazon. The assessment consisted of two coding questions of medium to hard difficulty, focusing on data structures, algorithms, and problem-solving skills. The questions required efficient solutions with optimized time and space complexity. After the OA, shortlisted candidates typically proceed to one or more technical interview rounds covering coding, system design, and behavioral questions based on Amazon's Leadership Principles.
Applied online via career site, received OA link within 2 days and cleared it, Round 1- DSA, Round-2 DSA, Round 3- System Design, Round 4- Mixed Technical Discussion and Behavioral.
