Ho presentato la mia candidatura tramite l'università. La procedura ha richiesto 3 giorni. Ho sostenuto un colloquio presso Amazon (Bengaluru) nel mese di giu 2020
Colloquio
First Round: (Online round with three sections) - Code debugging questions: Here they had given a small piece of code to debug - Aptitude/Reasoning/Critical Thinking questions: These were simple questions based on profit/loss, probability, basic math, sequences/series, alphabetical encoding of words etc. Coding Questions: 2 programming questions in C/C++/Java. involving binary search, DFS, job scheduling applications, etc.. Different candidates had different questions. --28 students were shortlisted for the second round-- Second Round (interviews). Mainly involved two parts: - Part 1 (Theory): He asked me about DSA, OS and code syntax questions - Part 2 (problem solving): He asked me to write down code for some basic algorithms on paper(not pseudo code). Next he checked for OOPS knowledge and approach by giving a situation and asking to design it using OOPS. Next, he asked one more DSA question on trees and optimise the algorithm, and ended with a question on DBMS.

Domanda 1
Given a positive 32-bit integer n, you need to find the smallest 32-bit integer which has exactly the same digits existing in the integer n and is greater in value than n. If no such positive 32-bit integer exists, you need to return -1.
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.

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.

Online Assessment is the first step in the process. I didn’t have an HR phone screening and went straight to the OA after applying. It was sent to me about a week after I submitted my application.

The first question is LeetCode style algorithms question, and the second question gives a full stack repo (choice of Java, NodeJS, or Django) and asks to solve a backend issue which is causing a bug in the frontend. Unit tests must pass to pass the second question. You can run both backend/frontend indivdually or together
