I applied through a recruiter. The process took 4 weeks. I interviewed at Amazon (Zagreb) in Dec 2014
Interview
Amazon had hiring event in my town. They contacted me via LinkedIn couple of weeks (I think it was around 8 weeks) before the on-site interview was being held. First, I solved two coding challenges online and then had on-site interview. On-site interview was actually 5 different interviews - 1 hour each. There were also 5 different interviewers. At the end of each interview they had one or two questions regarding social skills and then 5 or 10 min for my questions.
Interview questions [1]
Question 1
Serialization and deserialization of a tree to a string. If every node of tree represents a letter serialize tree to string in a way that you can deserialize the same string to a tree again.
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.

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
