I applied through a recruiter. The process took 1 day. I interviewed at Amazon (Hyderābād) in Aug 2012
Interview
first round was a written test which had 3 question completely based on Algorithms and Data Structures which lasted for 2 hrs.
In second round first i was asked about my projects and then he gave me one question to code and ten a series of question and asked me to tell the solution orally, all of them were on algos
Third round i was asked abt project first and then a question to code on algos
fourth round was same as third round but he was very particular abt questions on my project and the question i was asked to code was difficult than the previous ones
Interview questions [1]
Question 1
most difficult question was on infinite array. They keep changing some information given in the beginning and ask us how would that change our solution.they keep asking u did u complete many times which means they expect u to code fast
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.
