Step-by-Step Amazon Interview Process

Every stage of the Amazon interview process explained in detail with tips and what to expect.

1Online Assessment (OA)

70-90 min

Two coding problems on a timed platform. Typically LeetCode medium difficulty. Also includes a work simulation or leadership principles questionnaire.

What to Expect:

  • 2 coding problems (usually medium difficulty)
  • Work simulation or situational judgment test
  • Leadership principles questionnaire
  • Automated proctoring (webcam may be required)

Pro Tip: Practice timed coding on LeetCode. Focus on arrays, strings, trees, and graphs.

2Phone Screen

45-60 min

One or two coding problems with a live interviewer. You'll share your screen and code in real-time. The interviewer may ask behavioral questions as well.

What to Expect:

  • 1-2 coding problems via shared editor
  • Brief behavioral questions (5-10 min)
  • Live screen sharing with an Amazon engineer
  • Questions on data structures and algorithms

Pro Tip: Think out loud. Clarify requirements before coding. Explain your approach step by step.

3Onsite Loop (4-5 rounds)

4-5 hours

Four to five back-to-back interviews: 2 coding rounds, 1 system design (for SDE II+), and 1-2 behavioral rounds focused on leadership principles.

What to Expect:

  • 2 coding interviews (45-60 min each)
  • 1 system design round (SDE II and above)
  • 1-2 behavioral rounds on leadership principles
  • Each interviewer submits independent written feedback

Pro Tip: Use STAR method for behavioral answers. For coding, optimize after brute force. For system design, drive the conversation.

4Bar Raiser Round

45-60 min

A specially trained interviewer from a different team evaluates whether you raise the hiring bar. This round is a mix of coding and deep behavioral questions.

What to Expect:

  • Interviewer is from a completely different team
  • Mix of coding and deep behavioral questions
  • Probes for leadership principles alignment
  • Has veto power over the hiring decision

Pro Tip: Be authentic. The bar raiser looks for strong leadership principles alignment and problem-solving depth, not perfection.

5Hiring Committee & Offer

1-2 weeks

All interviewers submit written feedback. The hiring committee reviews and makes a decision. A recruiter will reach out with an offer or next steps.

What to Expect:

  • All interviewers submit detailed written feedback
  • Hiring committee reviews all feedback collectively
  • Recruiter reaches out within 1-2 weeks
  • Offer includes base, signing bonus, and RSUs

Pro Tip: If you get an offer, negotiate. Amazon offers are often negotiable on signing bonus and RSU vesting.

Leadership Principles

Amazon evaluates every candidate against 16 leadership principles. They are the backbone of every behavioral question.

Coding Rounds

Expect LeetCode medium to hard problems. Arrays, trees, graphs, and dynamic programming are the most common topics.

Bar Raiser

A specially trained interviewer from another team who has veto power. Focus on depth, authenticity, and leadership principles.

Everything You Need to Know About the Amazon Interview Process

How Long Does the Amazon Interview Process Take?

The typical Amazon interview process takes 4-8 weeks from application to offer. However, timelines can vary significantly based on the role, team, and hiring urgency. Some candidates report receiving offers within 3 weeks, while others wait up to 10 weeks.

The longest gaps usually occur between the phone screen and the onsite loop, as scheduling 4-5 interviewers can be challenging. If you have competing offers, let your recruiter know, as this can often accelerate the process.

What Makes Amazon's Process Different?

Amazon's interview process stands out for two key reasons: the leadership principles and the bar raiser. Unlike Google or Meta, where behavioral rounds are a smaller portion of the evaluation, Amazon dedicates 40-50% of the interview to behavioral questions tied directly to their 16 leadership principles.

The bar raiser is another unique element. This is a specially trained interviewer from a completely different team who has the authority to veto a hiring decision. Their job is to ensure every new hire raises the overall quality bar of the company. The bar raiser looks for depth of thinking, genuine alignment with leadership principles, and strong problem-solving skills.

Amazon Online Assessment (OA) Details

The online assessment is usually the first technical step. It consists of two coding problems to be solved in 70-90 minutes. Problems are typically at the LeetCode medium level, though some candidates report seeing easy or hard problems depending on the role level.

In addition to coding, many OAs now include a work simulation component where you make decisions in hypothetical Amazon workplace scenarios. These scenarios are designed to assess your alignment with leadership principles. There is no "right" answer, but consistency and clear reasoning matter.

How to Prepare for the Amazon Onsite Loop

  • Prepare 2 STAR stories per leadership principle: You will be asked about multiple principles across rounds.
  • Practice coding under time pressure: Use a timer and whiteboard or plain text editor.
  • For system design: Start with requirements, sketch architecture, then deep-dive. Reference AWS services.
  • Pace yourself: 4-5 hours is a marathon. Bring water, eat beforehand, and take bathroom breaks between rounds.
  • Ask questions: Each interviewer expects you to have 2-3 questions about their team and work.

Amazon Offer Negotiation Tips

Amazon offers are structured as base salary + signing bonus + RSU (stock) over 4 years. The unique aspect of Amazon's compensation is the back-loaded vesting schedule: 5% in year 1, 15% in year 2, 40% in year 3, and 40% in year 4. The signing bonus compensates for the low vesting in years 1-2. Base salary was capped at $160K until 2022, when Amazon raised it to $350K to stay competitive. For most SDE roles, higher compensation still comes through stock. When negotiating, focus on RSU grants and signing bonus for maximum flexibility.
