J'ai postulé via la recommandation d'un employé. Le processus a pris 1 jour. J'ai passé un entretien chez Amazon (Seattle, WA) en juil. 2011
Entretien
The interview was with the development team and it consisted of 45 minutes of 4 back to back rounds of white board coding with 5 minutes break in between each rounds. Before the interview we had lunch with the team. Then I was taken to a presentation room where I had all the interviews. They said me that I could code in whatever language I was comfortable with.
Performed well in all but one. Waiting for the result.
Questions d'entretien [4]
Question 1
The first interviewer asked me to code a program to evaluate a post fix expression.
Second one asked me to design a Conway's Game of Life. (I had no idea what it was. The interviewer took 5 minutes to explain the game and then asked me to design and code).
In the next round, the interviewer gave me a binary tree and asked me to write all the data in a file and when the file is read back we should be able to construct the original binary tree.
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.

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.
