Solicité el puesto a través de la escuela superior o la universidad. Acudí a una entrevista en Amazon (Calcuta) en oct 2019
Entrevista
One online round followed by 2 face to face interview rounds. Online round consists of around 10-20 mcq and 3 coding questions of easy level. During each round of face 2 face interview, was asked about projects and 1 coding question each round of med-high difficulty.
Preguntas de entrevista [1]
Pregunta 1
1. Given a two linked list containing numbers. Add them and return a linked list containing the sum of two numbers.
2. Given a binary tree, add another link to the right node of each node in same level.
Eg, Given tree containing links : 1-2, 1-3, 2-4, 3-5
Output tree containing links: 1-2, 1-3, 2-3, 4-5
3. Questions based on projects mentioned on CV.
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.

Pregunta 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.
