Me postulé a través de una facultad o universidad. El proceso tomó 1 día. Acudí a una entrevista en Amazon (Bengaluru) en ago 2013
Entrevista
First round is online technical written test where 20 MCQ questions were asked from topics like Data structures, Operating Systems, Algorithms, Networking, Databases. Along with the MCQ there are 2 coding questions where you need to write the desired functionality using any of your language preferred. Main program will be hidden and you need to write the program in the text area where you can check the output/errors by clicking on Compile and Run button. Many people find this kind of compiler is difficult to code.
Followed by 2 Technical rounds each of around 75 - 90 mins. They will test your analytical, logical approach to the problems and expect you to code them in the best way possible (optimizing space and time). All the border conditions will be checked if we have missed anything or not.

Pregunta 1
Explain about the garbage collection? If you want to implement the garbage collection in any of your preferred language, how do you code the manual garbage collection function.
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.
