Amazon interview preparation
Amazon OA and SDE interview practice — plus how to prepare for the Leadership Principles.
Mock interviews
The interview process (as widely described)
- Online Assessment (OA) — usually 2 coding problems, often with a work-style survey and sometimes a short scenario section.
- Interview loop — several rounds, each mixing coding / problem solving with behavioural questions based on Amazon's Leadership Principles. One interviewer is a "Bar Raiser" from another team.
The Leadership Principles matter as much as the code
Prepare 6–8 real stories from projects, internships or college (STAR format: Situation, Task, Action, Result) that show principles such as Customer Obsession, Ownership, Dive Deep, Bias for Action and Deliver Results. Use numbers in your results ("cut build time from 10 to 4 minutes").
How to practise here
Heaps, graphs (BFS), hashing and LRU-style design come up often in Amazon-style practice. Take the OA-style mock — 2 problems in 70 minutes — then review which tests failed.
