I applied through a recruiter. The process took 3 months. I interviewed at Amazon in May 2014
Interview
I am from Madrid, Spain and the position was for Seattle, WA.
I contacted a recruiter via email. The whole process took 3 months.
They sent me a link to do an online test, through interviewzen. It consisted in two parts:
- Java coding. It was about binary trees and recursion.
- OOP question. It was about inheritance and polymorphism.
I passed the test so they scheduled a technical phone interview with an engineer few weeks later. This was the script:
1) Questions:
- First question apart of “Is this a good moment?”: Why do you want to work here? => You better be ready for this.
- Which projects of your career are you proud of?
- Which languages are you familiar with?
- Why? => I didn’t expect this question.
- Are you familiar with trees?
- Really? What is a tree?
2) Technical part, coding.
- We used collabedit.
- It was about binary trees and recursion again.
- It’s not worth it to put the question itself, just be ready to be asked about data structures, recursion and efficiency in terms of Big O.
3) Interviewing the interviewer.
- You should have 3-5 questions for them.
It took one hour and one minute.
They sent an email 3 days later saying "we have decided to move forward with the search process in order to target the candidate…”.
Looking backwards I don’t think it was difficult. I wasn’t ready enough.
They were very kind with me all the time and I learnt a lot during the process.
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
I applied online. I interviewed at Amazon (Santa Clara, CA) in Jun 2026
Interview
Recruiter reached out and set up an onsite loop after the initial steps. Four back to back rounds in one day. Two coding heavy rounds run by senior engineers, one round with the hiring manager, and one behavioral round with a bar raiser. Mix of leadership principles and data structures throughout. Heard back within a week.

Question 1
Standard BFS grid problem. Given a grid, find the time for all cells to reach a target state where the spread happens one layer at a time.
How did you answer: Clarified the constraints, walked through the approach, then coded a clean BFS from all starting points at once. Tracked the number of layers until everything was covered.
