J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 2 mois. J'ai passé un entretien chez Amazon (Seattle, WA) en févr. 2012
Entretien
I had two telephonic interviews for about 45 mins each. The focus of the interviews was data structures, algorithms, oo design concepts and basic coding. Once I cleared the telephonic interviews, I was called in for an onsite interview which again focused on the same areas but little more in depth. I had 4 45 min 1:1 technical interviews. I had to work on one problem in each of the rounds. Problems focused on random numbers, trees and problem solving. I had 1 hour of lunch interview with the hiring manager. He explained about the group, work culture. He asked me to talk about my research and asked one technical question at the end. I liked the people. Casual work culture.
Questions d'entretien [2]
Question 1
Given a list of numbers and a rand(0,1) function, which returns a random integer between 0 and 1. Provide an algorithm to randomly sort the given list, based on the output of the rand() function, which should be called once for every number on the list. Code the solution in any language of your choice.
Given a tree(not a binary tree) and 2 nodes on the tree. Give an algorithm to find the least common ancestor of the given nodes. Code the solution in any language of your choice.
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.
