I applied online.

The Amazon SDE 1 interview process typically consists of three main stages, heavily emphasizing technical proficiency and Amazon’s 16 Leadership Principles (LPs).

1. Online Assessment (OA)

The first step is a 70–90 minute proctored assessment on HackerRank. It usually includes:

• Two Coding Questions: Medium-level DSA problems (e.g., Arrays, Strings, Hashing).
• Work Simulation: A 60-minute module where you handle workplace scenarios and decision-making.
• Workstyle Survey: A personality test to assess cultural alignment with LPs.

2. Phone Screen

A 45–60 minute technical interview with an engineer focusing on medium-level coding, edge cases, and a brief discussion on one or two Leadership Principles.

3. Onsite "Loop"

This final stage consists of 4 to 5 rounds, each lasting one hour:

• Coding (2 Rounds): Deep dives into DSA, focusing on clean code and optimization.
• System Design/LLD (1 Round): Basic architecture or Low-Level Design (e.g., designing a parking lot).
• Bar Raiser: A rigorous round with a senior interviewer outside the hiring team, focusing heavily on Leadership Principles and high-level problem-solving.
