Me postulé a través de una facultad o universidad. El proceso tomó 4 semanas. Acudí a una entrevista en Amazon (Atlanta, GA) en oct 2013
Entrevista
Got in contact through college career fair. Had a 45min on-campus interview 3 weeks later. The interviewer was very friendly, he gave helpful hints on how to solve the coding problems. He walked me through my code and pointed out where needs improvements.
Some problems he asked were:
Given an integer array, find any integer that occurs more than once.
Given a binary tree, test whether it is a BST.
Given two random nodes in a tree, not necessarily a BST, find their common parent.
They really focus on memory usage and time complexity of your algorithm/data structure.

Given any binary tree, write an method to test whether it is a Binary Search Tree
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.

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.

Pregunta 1
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
