I applied online. The process took 2 months. I interviewed at Amazon (Seattle, WA) in Aug 2024
Interview
3 60-minute interviews with different hiring managers.
1st one asked for a quick intro and 2 leetcode mediums (
2181. Merge Nodes in Between Zeros and 1190. Reverse Substrings Between Each Pair of Parentheses)
2nd one asked 3 behavioral questions. Describe a moment where you had to dive deep, describe feedback you've received, and describe a time when you would change something if you could.
3rd one had 2 behavioral questions and 1 coding question. Think of a time when you could not deliver something on time. Think of a time when you ran into an issue and had to rethink your approach. Leetcode problem was Design In-Memory File System

Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.
Interview questions [1]
Question 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
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.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.
