J'ai postulé via un recruteur. Le processus a pris 1 jour. J'ai passé un entretien chez Amazon (Seattle, WA) en mai 2011
Entretien
Posted resume on Dice, contacted by their recruiter to set up phone screen. Their engineer called on time. Asked a few technical questions. First briefly went through my background. First question was how do we use MVC model in previous project. Interviewer does not have strong telecom experience, so had to explain to them in details. Second question was about inheritance and composition, explained to him as IS/HAS relationship. Was asked which one is better, I told me it depends on the system that you want to model, not one better than the other. Also was asked to provide real life example from previous project, instead of fake examples. Not sure how he takes my answer. Third question was to come up with algorithm to find intersection of two linked list. Interviewer was patient to guide through the thinking process, but still a pain. Came up one basic solution, then he asked for alternative solution to improve the performance. Gave him something like searching for sub-string. Don't know how he like it or not. Had brief conversation with him about their interview process is better for fresh graduate student rather than experienced engineer. He said Amazone is hiring for the whole company rather than specific group.
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.
Questions d'entretien [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.
