I applied online. The process took 4 weeks. I interviewed at Amazon (Madrid) in Oct 2021
Interview
A long process, approximately a month and a half, with three types of interviews: coding assesment, by telephone and on-site (which was also done online due to the COVID situation).
The interviewers were very friendly, helpful at all times and made the conversation quite pleasant.
It is highly recommended to use leetcode to practice exercises and review the most common data structures and algorithms. The book Cracking the Coding Interview is very useful for the interview.
Interview questions [1]
Question 1
Coding assesment: two exercises similar to those in leetcode and a question for each one about complexity.
Phone Interview: questions on Amazon's leadership principles ("name a time when you had a deadline coming up and had to ask for more time") and a mid-level programming exercise.
On-site Interview: three interviews with different Amazon developers, about 45 minutes each. In all three, questions on Amazon's leadership principles and a programming exercise (OOP, data structures and a difficult exercise, which they don't expect you to come up with the solution, but to discuss how you could solve it).
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.
I applied online. I interviewed at Amazon (Calgary, AB) in Jun 2026
Interview
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.
Interview questions [1]
Question 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
