J'ai postulé en ligne. Le processus a pris 4 semaines. J'ai passé un entretien chez Amazon (Seattle, WA) en févr. 2011
Entretien
I had two phone screens. The first one was relatively easy and I was asked 1 programming question. One about reversing a string . The second interview consisted of two questions, the first question was to find whether any two numbers in an array sum up to give a third and the second question was to print a matrix in spiral order. After the two interviews I received an email from the recruiter to schedule a third. The third interview consisted of more theoretical questions such as define OOP and was also a little behavioral (interviewer asked me about my projects, about working in teams etc.) The coding question was to find a pythagoran triplet in an array which I solved in O(n^2) time using a hash table. I thought my last interview went pretty well but I did not receive an offer.
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.
