Solicité el puesto a través de la recomendación de un empleado. El proceso duró 2 días. Acudí a una entrevista en Amazon (Bengaluru) en ene 2016
Entrevista
I went through referral. The first round was written. I was supposed to answer 3 question. Then there are next 4 face to face techinical round where they observe your way to approach to solution. You need to know all good algorithm to solve question. Face to face round will be of 45 minutes to 1 hour. And you're expected to answer 3 question during that. Even if you know the question don't bang on. Solve from the brute force and then optimize it.
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.
Preguntas de entrevista [1]
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.
