J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 7 mois. J'ai passé un entretien chez Amazon (Vancouver, BC) en sept. 2012
Entretien
I interviewed with Amazon over the phone for the SDE position. I had dropped of my resume with one of their representatives at a career fair at my school in January 2012, and received an email in September asking to schedule an interview.
My first interview over the phone did not go very well, as it was my first interview for a software company--over the phone, no less--and was rather nervous. The second interview went much better as I was more prepared and a lot more confident. Both interviews started off with a brief introduction where I was asked to tell the interviewer about who I was and some of the projects that I had worked on in the past. We then moved on to the technical questions; some of the questions asked were: what is the difference between a binary tree and a binary search tree, how do you detect a cycle in a singly-linked list, and a more complicated programming question.
I received an email the week after my second interview saying that I would not be advancing further in the interview process.
Questions d'entretien [1]
Question 1
Given a set of number ranges, i.e. [1,5], [3,6], [7,9], write a program to merge overlapping number ranges. In the above example, the result should be [1,6], [7,9].
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.
