I applied through university. The process took 2 days. I interviewed at Amazon (Bengaluru) in Sept 2013
Interview
This is my experience during the campus selection drive of Amazon.com. The process started with a brief presentation by the recruitment team. The process had 5 stages. The first test was online, having 20 objective questions from various topics and 2 questions to code. One required a complete code, the other required coding a method for the specified purpose. This was followed by four technical interviews. Each interviewer constantly typed on their laptop while interviewing us, probably making a note about us. We had to think of a solution for the given problem and optimize the same. This was a "white board" test, which required us to write actual code for the solution. The questions were pretty tough, but were manageable. The interviewers were very friendly and were very open about their work culture.

Question 1
The most difficult questions were from data structure implementation point of view. They required a strong understanding of the problem statement to decide the correct data structure to implement. They were very stern about the required efficiency of the solution. Getting a solution wasn't enough, we are expected to give the best solution we can possibly think of!
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.
