I applied online. The process took 4 months. I interviewed at Amazon (Toronto, ON) in Aug 2025
Interview
The process was broken into 3 parts. After applying in April, I did the online assessment (LeetCode-style coding + workplace simulation) later that month. In August, I received an invite for a 3-round interview:
Round 1 (Behavioral + LLD): A couple of Leadership Principle questions, plus a simple low-level design question (“Pizza Shop”).
Round 2 (Coding): One LeetCode Hard (BFS/DFS + topological sort). Couldn’t run code in their IDE, so I had to walk through it mentally.
Round 3 (Behavioral): LP-focused, mostly building off one story.
Overall, structured but tougher than expected, especially the coding round.
Online assessment which took 4 hours and then 3 rounds of interview 2 of them were technical leetcode style and last one was behavioral interview. Overall it was a great experience.
