A Complete Guide to Amazon Interview Process and Coding Interview Questions
Do you know that only about 2% of those who apply at Amazon get through? The tech giant has a pretty rigorous hiring process. The recruiters carefully select all the Amazon coding interview questions to test the overall abilities of the applicants.
To face the Amazon coding challenge questions, you’ll need a lot of practice, guidance, and the correct strategy. As the company receives thousands of resumes every year, you’ll need to ace your tech interview to get through.
If you intend to acing Amazon’s coding interview, you must adopt the right strategy. Without that, beating the stiff competition is an uphill climb.
In this article, we’ll look at the type of Amazon coding interview questions you can expect. These are the things we will discuss:
- The Complete Amazon Interview Process
- Different Levels at Amazon

The Complete Amazon Interview Process
Before we get to Amazon coding interview questions, we’ll begin with everything you need to know about how Amazon conducts its interviews and what they’re looking for. Let’s jump right in!
How are the Profiles Shortlisted at Amazon?
The process of profile shortlisting at Amazon is as follows:
- First, the applications come from websites/job boards, and recruiters search profiles from social media and references.
- Then, L4/L5 initial automated filtering happens based on skills.
- Next, for all levels, the recruiters do manual shortlisting.
- Finally, before the initial conversation, the recruiter forwards the shortlisted candidates to the Hiring Manager (HM). They provide about 20-30 profiles per week to HM, and currently, 30% of sourcing is done by the HM. Amazon also makes use of the LinkedIn commons project.
Did you know? At Amazon, a Hiring Manager creates a job opening based on new needs or for attrition replacement. Annual planning starts in July at Amazon and ends in October. In this plan, the increased headcount is approved based on business growth. In fact, each job opening is approved by the finance and recruiting team, boss, and super boss. There is also a system to track all open positions and their state.
What Is Unique About Amazon’s Interview Process?
For the most part, the Amazon interview process is similar to other FAANG companies. However, they have a couple of key rounds and certain Amazon coding challenge questions that make the interview process unique.
The Loop is centered around Amazon’s 14 leadership principles:
Unlike most other companies, in the Amazon on-site interview, the Loop is heavily centered around the company’s 14 leadership principles. Recruiters evaluate you against these leadership principles directly or indirectly at any on-site interview stage.
The presence of a Bar Raiser:
Amazon also has a special “Bar Raiser” round, where specially trained employees (known as Bar Raisers) gauge if you’re the right fit. The primary function of the Bar Raisers is to maintain the hiring bar high by seeking out only the best talent. They have a decisive say in the interview’s outcome, so if you ace the core technical rounds and Amazon coding challenge questions, you must pass the bar raiser round to lock an offer.
To become a bar raiser, an interviewer should have done 100+ interviews. The bar raiser has to undergo special training and shadow other bar raisers. The bar raiser may not be from the team you’d be joining, but they may be under the same VP org. The bar raisers evaluate if the candidate is better than 50% of the existing employees.
With the two major unique factors discussed, let us now look at the Amazon interview process in more detail.
Various Rounds at the Amazon Interview Process
While Amazon coding interview questions are a crucial part of the process, there are other two important stages. The Amazon technical interview has these three main stages:
- The initial phone screen
- The Amazon coding assignment
- The Loop
Before these stages, recruiters have the first round of conversations to check your communication skills, interest in Amazon, immigration, relocation, salary requirement, etc. Let’s now look at what happens in each of these rounds:
1. The Initial Phone Screen
This round happens with a recruiter from Amazon who will get in touch with you after your profile gets provisionally shortlisted for the role. The recruiter will ask you questions about your experience, core skills, and expectations from the role.
- A phone screen is done by someone mostly from the same team. For ICs, an L7 does it, and for managers, a manager does it.
- Position fit, leadership skills, and functional skills like design, coding, and people skills are checked here.
- In this round’s coding questions, an automated tool is used to evaluate.
You can also expect a couple of behavior-related questions in this round. At the end of the interview, the recruiter will set a date for you to take up some Amazon coding challenge questions.
For more details on Amazon phone questions and how to answer them, check out the “Amazon Phone Interview Questions” article.
2. The Amazon Coding Assignment
Depending on the role you’re applying to, the coding assignment happens either remotely or in person. For most developer positions, the coding assignment happens remotely. Considering the pandemic situation, Amazon decided that it would hold remote assignments monitored in real-time.
- The Amazon coding challenge questions involve solving 1-2 coding problems within a stipulated time. It usually happens on a coding interview platform or a Google Doc.
- The hiring manager evaluates your approach to solving the problems and how you go about arriving at the solution.
- At the end of the assignment, expect a few questions about the concepts you employed to solve the problem(s).
If your performance in the Amazon coding interview questions is satisfactory, a recruiter will get in touch with you to fix a date for the on-site interview.
3. The Loop
Amazon’s on-site interview, known as the Loop, is the final phase in the hiring process. Getting through this stage is significantly challenging as recruiters assess you on many aspects before making a hiring decision.
- For the interview, the Hiring Manager creates a panel of 4-6 interviewers, and each interviewer is assigned one functional area and 1-2 leadership principles. One of them is a bar raiser, who is nominated by the recruiter, and this interviewer is outside the hiring team.
- The panel consists of SDM, Sr. Eng. Manager, principal engineers. For SDMs, program managers/product managers are also there. Each panel member is at least the same level as the interviewing level.
Landing a software engineer job at Amazon is hard, given its rigorous interview process. Nailing it requires the right strategy and direction. Our “FAANG Interview Tips” is a good place to start your Amazon technical interview prep.
Amazon Interview Process for ICs Vs. EMs
For the on-site rounds, there are some differences between interviews of ICs and EMs:
Interview Process for ICs
For ICs, in each round, they’d likely ask you Amazon coding challenge questions and behavioral questions in any of the following combinations:
- Two behavior and one coding/DSA question
- One behavior and one system design question
- Three behavioral questions
In terms of questions asked to ICs at different levels,
- L4 doesn’t get system design questions, and for them, there’s very little focus on behavior. For L4, the focus is on the basics like conflict, adversity, etc.
- Starting L5, you get at least one system design question.
- The system design and behavior bar is high L6 onwards.
- For domain-specific positions like DE, DSc, and Embedded, coding is half DSA and half domain.
Interview Process for EMs
For EMs, the phone screen mostly involves experience and behavior. For each round, one behavioral and one system design or three behavioral questions are asked. The bar for system design and behavior is high from L6 onwards, and coding becomes less important.
The loop typically consists of the following rounds:
- Coding round: This round involves solving 1-2 Amazon coding interview questions around algorithms and data structures. The extent of your problem-solving skills is assessed in this round.
- Design round: Hiring managers evaluate your engineering design skills in this round. Your ability to design and work with scalable systems with low latency is assessed.
- Behavioral round: Behavioral interviews at Amazon are based on the company’s 14 leadership principles. The behavioral round is essentially built to test if your attitude and personality traits align with the company’s vision and goals.
- The bar-raiser round: Bar raisers are a group of handpicked employees trained to maintain the hiring bar at Amazon. Their primary role is to find the best candidates by assessing them against a set of predefined parameters. Bar raisers have a veto when recruiters make a hiring decision. If they deem you unfit for the role, you don’t get offered.
Note: Amazon tends to focus more on behavioral and design interviews for senior positions and coding interviews for junior positions. Additionally, coding interviews don’t have a veto while hiring for senior positions but design interviews have a veto for junior positions.

Amazon Systems Design Interview Questions
Distributed systems design is an important component in the on-site interview. The design round is particularly important for senior developer and managerial positions.
- At junior levels, you’ll usually be asked no design questions.
- At intermediate level, you can expect module or API design questions.
- Lastly, at senior levels, you can expect system design questions.
Here are some Amazon coding interview questions pertaining to distributed and large-scale systems:
- Design an in-memory database system
- Design an IP blocking system
- Design a voting system, where people will cast their votes and the votes get added to corresponding candidates
- Design a system to find 100 top-selling products in a given time window
- Design an Amazon online bookstore, where users can view prices and make purchases
- Design a system where an office administrator knows how many people are present on each floor of the building, given that the building has 3 floors
- Design a system to upload images with tags — users would be able to visit and search for images by entering the tags
- Design a notification service that sends notifications to multiple devices
- Design a comprehensive workflow system that responds to pause/continue functions
- Design a scheduler service that can manage huge schedules with minimal latency
- Design an Instagram or Tinder.
- Create a high level design of the black Jack video game
- Assuming no cloud services are available, how do you scale up a web server once its popularity increases.
For more details on Amazon system design questions and how to answer them, check out the “Amazon System Design Interview Questions” article.
Amazon Behavioral Interview Questions
Apart from Amazon coding interview questions, you will have to answer some behavioral questions too. Amazon’s behavioral interview is starkly different from other FAANG companies. Behavior and leadership questions are very important at Amazon. The behavioral questions are also based on leadership principles:
- At junior levels, learning and curiosity are important.
- On other levels, the leadership principles “disagree and commit”, “customer obsession”, and “hire and develop the best” is important.
Some leadership principles like frugality are many times not covered. Evaluation is subjective and is based on honesty, integrity, scope of the problem. To get a feel of what sort of questions to expect, we’ve listed some for you below along with the leadership qualities they test:
- Ownership: Give an instance where you had to communicate that you were not able to meet your commitments. OR Tell me an instance where you had to push back a product release because of quality issues.
- Customer obsession: When did you go above and beyond to meet a customer's needs? OR Give an instance when you had to take a customer’s stand in your organization and what happened?
- Deliver results: Narrate a difficult project or a failed project. What happened and what would you do differently?
- Disagree and commit: An instance where you disagreed with your manager and what happened?
- Simplify and innovate: When you got a requirement to implement, how did you simplify it to make it generic?
- Are right, a lot: Give me an instance, where you had to change your opinion/approach, which you strongly believed in.
- Learn and be curious: Give an instance where you were assigned a task, but you didn’t know how to go about doing it. How did you go about it?
- Hire and Develop the best: Did you hire someone who surpassed you?
Now that you have an idea of how leadership qualities are associated with behavioral questions, here are some more Amazon behavioral questions for practice:
- Tell us about a time a project you were working on went south. How did you manage the situation?
- Tell us about a time when your work-life balance was thrown off gear owing to a demanding project.
- Tell us about a time when you leveraged massive chunks of data to build a strategy. How did you execute it?
- Why do you want to work at Amazon? How do you think Amazon will impact your life in the coming years?
- What would be your stand if your supervisor asked you to do something outside the purview of the company’s policy?
- Tell us about a time when it was getting difficult to work with an uncooperative colleague.
- Tell us about a time when you apprised the entire team about crucial learnings that you derived while working on a project.

Scoring and Evaluating System at Amazon Interviews
After completing the Amazon interview process and answering the Amazon coding interview questions, you must wait for HR to contact you. Let's take a look at how Amazon's interviewers are evaluating you at the given time.
The scoring system involves each interviewer rating the interviewee for each assigned area:
- Very strong
- Not acceptable
- Strongly not acceptable
While filling in the score, they can’t see others’ scores.
Next, a debrief of all interviewers is held. During this debrief, the interviewers may change their scores. At the end of the discussion for hire, the HM and bar raiser have to agree. If they decide to hire, the level will be the same as interviewing for or lower. The level is finally decided by the HM and the recruiter.
While the questions at each level may be similar, the expectated outcomes are different at each level. So the levels can be decided by the quality of answers.
