Amazon Software Development Engineer - Amazon SDE Assessment

The Amazon SDE assessment is a key part of the Amazon SDE interview process, designed to evaluate candidates aspiring to become Software Development Engineers (SDE) or "SDE engineers" at Amazon. This assessment tests a wide range of skills, including coding proficiency, technical expertise, and problem-solving abilities, while also assessing personality traits and behavioral tendencies essential for success in a dynamic workplace.

Unlike standard technical evaluations, the SDE at Amazon assessment incorporates behavioral insights to predict how well candidates can adapt to Amazon’s fast-paced, high-performance environment. By combining technical challenges with personality-based evaluations, it offers a holistic view of a candidate’s potential to thrive and contribute to one of the world’s most influential tech companies.

Success in the Amazon SDE interview process requires both technical excellence and a deep understanding of the behavioral traits that align with Amazon’s work culture. Preparing effectively is essential for standing out in this competitive hiring journey.

Being an Amazon Software Development Engineer (Amazon SDE) is both a rewarding and challenging position. It is a dynamic role that requires strong technical skills, problem-solving abilities, and having overall characteristics that thrive in a fast-paced environment.

The core responsibilities of an Amazon SDE revolve around designing, building, and maintaining the software that keeps Amazon running. This can include the following tasks:

• Innovative Projects – Work on cutting-edge projects from scalable e-commerce platforms to AI solutions.
• Technical Challenges – Your work will often involve tackling complex technical challenges that include big data, performance, and security. Solve them with cutting-edge tools.
• Customer-Centric Approach – At Amazon, customer obsession is more than a motto. You will directly contribute to this mission by working closely with product and design teams to understand user needs. The challenge will be to translate those insights into innovative solutions.

The Amazon SDE Assessment is a critical initial step for candidates applying to SDE at Amazon roles, including Intern, New Grad, SDE I, SDE II, and SDE engineer positions, as well as SDET roles. This multi-part online test evaluates not only your technical skills, such as coding proficiency and problem-solving abilities, but also your cultural fit with Amazon’s principles.

The assessment includes coding challenges designed to test your ability to solve complex problems efficiently. It also features other sections, such as the Amazon Work Simulation and the Amazon Work Style Assessment, which measure your alignment with Amazon’s leadership principles and work culture. These components ensure that candidates meet the high standards expected of software development engineers at Amazon.

Components of the Amazon SDE Assessment:

1. Coding Challenge: Solve two coding problems to demonstrate your technical expertise.
2. Work Simulation: A scenario-based test to assess decision-making and problem-solving skills.
3. SDE Work Style Survey: Evaluates work preferences and tendencies to ensure compatibility with Amazon’s workplace.
4. Amazon Work Style Survey: Focuses on alignment with Amazon’s core leadership principles.

This structured assessment ensures that every candidate is evaluated thoroughly for their technical and behavioral readiness to excel in Amazon’s fast-paced, innovative environment.

The Amazon Software Development Engineer position accepts new graduates and interns to join. Although the application and assessment process are not the same as the other candidates, every Amazon SDE new grad will have to prove the same set of skills set and work values.

The Amazon SDE Assessment for new graduates and interns is divided in two parts:

Interns and New Grads

• Part 1 – OA1: Two coding questions
• Part 2 – OA2: Work Simulation and Work Style Assessment

Note: The practice tests, tips, and full explanations included on our Amazon SDE PrepPack are relevant for these tests as well.

The Amazon SDE Coding Assessment is a timed online programming test with two coding problems limited to 90 minutes. These involve mainly basic data structures and algorithm problems, easy-medium level. You can use any of these languages: Java, C, C++, Python, Ruby, JavaScript, Swift, Clojure, Erlang, among others.

The test measures the following abilities:

• Problem Statement Retention – Reading a problem and understanding what it's asking.
• Coding Ability – Understanding problems, figuring out solutions and translating those to code.
• Data Structure Application – Taking a problem and solving it in the simplest way by applying the appropriate data structure
• Runtime Complexity – Going over your own code and assessing major issues it might have.
• Simplification – Creating a simple solution to a complicated problem in a way most people would understand.

To prepare for the coding test Amazon suggests that you focus on algorithms, data structures, coding fundamentals, and high scale architecture.

Interviewing for a role of Amazon Software Development Engineer usually takes four to five weeks overall. Here’s a breakdown of the recruitment process:

• Submit a job application - Craft the perfect application with our Amazon resume tips.
