Two back to back interviews - both technical. In the first interview, a brief resume walkthrough and then a few questions about multithreading, trees etc. Then he asked me how to implement a queue using 2 stacks, how to do an in-order traversal of bst without recursion, compare time complexities of different operations in linked list and hash table. In the 2nd, he asked to implement algorithm to solve the word ladder problem given a dictionary. And how to implement a stack that supports minimum operation in O(1).

Question 1
He asked how to optimize BFS for the Word Ladder problem
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
I applied online. I interviewed at Amazon (São Paulo, ) in Jun 2026
Interview
Empresa extremamente clara sobre o que é pedido na entrevista e isso me mostra a seriedade. Minha experiencia foi positiva e tente se atentar a resolver o problema e não somente decorar padrões do leetcode.

I applied online. I interviewed at Amazon (Calgary, AB) in Jun 2026
Interview
Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

Question 1
The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
