I applied through an employee referral. I interviewed at Amazon (Bengaluru) in Feb 2019
Interview
Online Coding Test: Coding challenge (2 scenarios) and Coding approach (elaborate why you code the way you do) – 105 minutes: One question based on Two-pointer approach with extra use of hashmap, on was simple iteration with finding min in every loop. ( Tip: Solve all coding questions from interview experiences of GFG and LeetCode.)
Interview questions [1]
Question 1
Round 1:
Easy Graph application problem, Optimise it using DP, further optimise space by removing unnecessary data.
Easy Data Structures problem using hashmap and a counter.
Round 2:
Find the kth the smallest element in an array.
Binary Search tree problem(GFG medium level)
Round 3:
RU Cache Implementation
Round 4:
Implement Hashmap with a function that returns the order of insertion of <key, value> pairs into it
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.

I applied through college or university. I interviewed at Amazon (Patiala) in Jun 2026
Interview
Amazing process, was asked 2 dsa questions then hashmap internals and then basic introduction in dsa question i was given hints too, ovrall a great experience, will recommend everyone in the house
