I applied through college or university. The process took 1 week. I interviewed at Amazon (Hyderābād) in Jul 2010
Interview
I got shortlisted for interview via university placement programme. I was called to their office for interviews. I had 4 rounds of an hour each. All rounds focused on skills like Problem Solving, Coding, Data Structures and Algorithms. There were some puzzles in one of the rounds. One thing i want to highlight about coding is they take it seriously. You need to avoid any logical error with even the minutest of edge case and the code needs to be what they call "production ready".
The questions were pretty standard and a quick google search would tell you most of them.

Question 1
I was asked to explain my masters thesis work in detail
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.
