J'ai postulé via la recommandation d'un employé. Le processus a pris 1 semaine. J'ai passé un entretien chez Amazon (Mumbai) en févr. 2022
Entretien
Round 1: DSA round
The interviewer asked a question on Matrix (find the Kth smallest number in a matrix) which I solved using Binary Search but improvised it using Heaps, the interview went pretty long after 1 question he aseked me some behavioural questions
Round 2 was held on the same day which was a DSA round
Questions
1) Vertical Traversal of a binary Tree - solved using DFS traversal and then using Level order Traversal
2) A question on 2 pointer which was easy.
then few behavioural questions
2 days later I got a call from the recruiter and he scheduled my round 3
Round 3: DSA and Leadership
1 question on Graphs - Topological Sort - Alien Dictionary
then a long session on leadership principles
Round 4 - HR
Some basic HR questions
And on the next day I received a mail stating I was selected

Question 1
1) Find Kth smallest Element in a matrix
2) Vertical Order Tree Traversal
3) 2 pointer based question
4) Alien Dictionary
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.
