How to Get Hired at Amazon in 2025: SDE Interview Guide

Amazon's Hiring Philosophy: Leadership Principles First

Amazon's 16 Leadership Principles (What They're Really Testing)

LPWhat They're Evaluating Customer ObsessionDo you start with the customer and work backwards? OwnershipDo you act beyond your job description? Do you own outcomes? Invent and SimplifyDo you find elegant, simple solutions to complex problems? Dive DeepCan you pull data and go deep on technical detail? Bias for ActionCan you make decisions under uncertainty without over-analysing? Deliver ResultsDo you ship? Do you hit deadlines despite obstacles? Earn TrustDo you build trust with teammates and stakeholders?

Critical Rule: Prepare 2 unique STAR stories per LP. Amazon interviewers will explicitly say which LP they're testing.

The Amazon Interview Process

1. Online Assessment (OA)

Amazon OA problems often test arrays, strings, graphs, and greedy algorithms. Practice timed LeetCode sessions.

2. Phone Screen (1 round)

3. Onsite Loop (5–6 rounds)

The Bar Raiser: Amazon's Secret Weapon

Are from a different team than the one hiring
Have veto power in the debrief
Are looking for candidates who are in the top 50% of current Amazonians at that level

How to handle the Bar Raiser: Be specific, be honest, and don't embellish. If you made a mistake in a story, own it and explain what you learned.

Amazon Coding Interview: Patterns to Master

Arrays & Sliding Window — *Sliding Window Maximum, Minimum Size Subarray Sum*
Trees — *LCA, Zigzag Traversal, Right Side View*
Graphs & BFS — *Word Ladder, Number of Islands*
Heaps — *Meeting Rooms II, K Closest Points*
String manipulation — *Integer to Roman, Valid Parentheses*
Two Pointers — *Container With Most Water, 3Sum*

System Design at Amazon

Design Amazon's order management system
Design a distributed rate limiter
Design a notification system (SNS/SQS concepts)
Design S3 (object storage at scale)
Design a recommendation engine

Writing STAR Stories That Land Offers

A specific situation (not hypothetical)
Your actions (not "the team")
Measurable outcomes (numbers, percentages, timelines)

Common Reasons Amazon Candidates Fail

Generic LP answers — saying "we" instead of "I", no specific metrics
Weak system design — not knowing AWS services or distributed systems trade-offs
Failing the Bar Raiser — not being a clear step up from the average hire
Poor communication — not structuring answers clearly under pressure
