J'ai postulé via la recommandation d'un employé. J'ai passé un entretien chez Amazon
Entretien
Had two rounds of phone interview, completely technical. In the first round I was asked to write a program, and then apart from that questions based on sorting were asked. In the second round, had to talk to a chinese guy and I had problem communication with him. This round consisted of writing one program, which I did but i found it a little difficult to explain the recursion part via phone.

Question 1
1) Input: An integer. O/P: reverse the byte order(not the bits, reverse each byte order, i.e. order of 1's and 0's should not change within each byte) and display the number.
2) Find and display all anagrams of a given string. This one is nothing but permutation of a string.
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.
