Amazon Software Development Engineer Interview Process

The amazon software development engineer interview process is lengthy and exhaustive. Here’s what you can expect:

1. HR interview: The preliminary step of the interview is focused on understanding the candidate’s interests and why the candidate would be a good fit for the company. Once the recruiter is satisfied with your answers, you would be given an online assessment to solve, or a technical screening would be scheduled based on the profile you have applied for.  

2. Amazon Online Assessments: This online assessment is usually a part of the hiring process for interns and fresher candidates. Sometimes, it is also included for experienced candidates. The assessment has three sections:

  1. Debugging questions: A set of seven debugging questions will be assigned to you with an allotted time of 20 mins. Java, C, and C++ will be the three coding languages available for you to solve this assignment.
  2. Questions on Coding: The second assessment would comprise two questions based on data structure and algorithm. You can use any of these languages: C, C#, C++, Java, Ruby, Swift, JavaScript, and Python.
  3. Questions based on work simulation and logical reasoning: There are two parts to this assessment; In the first part, you would be given various scenarios from the life of a software development engineer, and your responses to it would be analyzed. The second part would contain 24 multiple choice questions based on logical reasoning. 

3. Phone Screen: During this round of technical phone screening, you will be asked a set of technical and behavioral questions. The entire session goes on for 45-60 mins, and the recruiter is mostly your potential manager. During this round, be sure to express your understanding of Amazon’s leadership principles. 

4. On-site interview: The most elaborate interview consists of 4-6 rounds of 60 mins each. Some of the interviews will assess your coding knowledge, while others will assess your system design skills, and one topic common to all the interviews is behavioral questions. 

One of the last interviews, called the “bar raiser,” is conducted by experts to see that for each competency that they test, you are least as good as or better than the average Amazon SDE. Needless to say, this round is tough to crack!

What to Expect During an Amazon SDE Interview Process

As from the previous two subsections, you might have understood the intricacy of the entire interview process. So, we have broken down the entire Amazon Software Development Engineer interview process into three major components to help you plan your prep. 

1. System Design

Amazon has a large consumer base, so they are always looking for software development engineers who can design scalable systems. Commonly asked system design interview questions are:

  1. How would you design a payment system for parking lots?
  2. How would you design a warehouse system for our company?
  3. Design a counters system for online services. 
  4. Design a URL shortening system. 

Simple ways to ace the system design interview questions are: reading books like “Designing Data-Intensive Applications” by Martin Kleppmann, brushing up on fundamental concepts, and practicing mock interviews.

2. Coding 

Coding forms an integral part of any technical interview, be it for a software developer, software engineer, or technical lead role. One of the frequently asked questions in the Amazon Software Development Engineer Interview is based on coding. The examples of questions asked are:

  1. Construct a binary tree, given preorder and inorder traversal of a tree. (Solution)
  2. Find the missing number in the array; an array of positive numbers is given from 1 to n; you have to find two missing numbers in the array. (Solution)
  3. Design a stack that should support push, pop, and top and retrieve the minimum element in constant time. (Solution)
  4. Determine if the given binary tree is a search binary tree. (Solution)

The best way to clear the coding questions asked during the online assessment or in an on-site interview is to at least dedicate three months of self-study. During this period, you should review your basics; study the concepts of algorithms, system designs, OS, and concurrency. 

3. Behavioral Questions

Amazon strongly believes in its 16 leadership principles, so behavioral questions are a part of every round of interviews. Compared to other FAANG companies, in Amazon Software Development Interview, the answers to behavioral questions hold much greater importance. The common behavioral questions asked are:

  1. Share the lessons you learned when you took a calculated risk and failed?
  2. Tell us about a time you had to handle a difficult customer.
  3. Describe an incident where you had to make an important decision without receiving approval from your boss.
  4. What is one of your most innovative ideas?
  5. How do you prioritize your work?
