I was referred by a friend, I was giving coding problem to solve online. The problem is not timed but they expect you to finish within two hours, and the session is recorded for review. You have to code online. One of the developers will review the code and also watch a video to see how you solved the problem. I did not finish it in two hours.
The question:
Implement a class with 3 public methods that operate on a common set of data. These functions record the weight of boxes and allow users to find the weight of a box at a given percentile. the functions have the following signature.
void writes(string boxId, Double weight);
Double getWeightByboxId(String BoxID);
Double getWeightAtPercentile(Double Percentile);
I have a solution but let see what others will do
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
