Full Experience
Hi I gave intreview in Amazon recently for SDE-3 position. Round1 : variation of this https://leetcode.com/problems/add-two-numbers-ii/
LL Round: Given multiple items with dimensions (length, width, height) and multiple boxes with dimensions (length, width, height), find the smallest box that can fit all items.
HLD Round: Vending machine HLD. Need to notify operators when items are running low or out of stock. Further enhancements included supporting multiple vending machines within a building, allowing users to place orders directly from their desks and have them fulfilled by the nearest vending machine with available inventory.
Interview Questions (3)
Add Two Numbers II (variation)
Given two non‑empty linked lists representing two non‑negative integers, where each node contains a single digit and the digits are stored in forward order, add the two numbers and return the sum as a linked list. The interview used a variation of this problem.
Find Smallest Box to Fit Items
Given multiple items with dimensions (length, width, height) and multiple boxes with dimensions (length, width, height), determine the smallest box that can fit all items.
Vending Machine High-Level Design
Design a vending machine system that notifies operators when items are running low or out of stock. The design should support multiple vending machines within a building, allow users to place orders from their desks, and fulfill orders using the nearest machine with available inventory.
