Amazon QA engineer interview questions are designed to assess a candidate's technical expertise, problem-solving abilities, and attention to detail. Whether you're an experienced QA engineer or preparing for your first interview at Amazon, understanding the types of questions you may encounter is crucial.
Amazon operates across several industries providing customer-focused products and services. Quality is an essential facet of Amazon’s consumer-centric vision.
Quality Assurance (QA) engineers at Amazon work closely with software developers to evaluate the functionality of products and services through manual or automated tests. QA engineers run a series of test suites and cases to identify product defects and drive quality initiatives.
In this article, we’ll look at the Amazon quality assurance engineer interview process, including the type of questions asked at the interview. We also offer tips and insights to help you prepare for and ace your upcoming QA interview.
Amazon QA Interview Process
Amazon’s QA engineer interview process is similar to Amazon’s coding interview process. Amazon’s QA interview process comprises the following 5 stages:
1. Evaluation of Your Coding Skills
Your knowledge of basic data structures (Arrays, Strings, Linked Lists, etc.) is assessed at this stage. To ace this coding interview, you have to be adept at an object-oriented programming language such as Java, Python, or C++.
2. Evaluation of Your Testing Skills
At this stage of the Amazon QA engineer hiring process, you will be evaluated on your ability to plan and execute test strategies in a real-time situation. Experience in software testing is necessary to be successful in this round.
3. Evaluation of Your Analytical Skills
Your ability to debug code, among other analytical skills, will be assessed in this round. Although similar to the coding interview, questions asked in this round will be more challenging and will involve algorithmic problems.
4. Evaluation of Your Behavioral Skills
Amazon follows a unique method to evaluate candidates’ behavioral skills. Amazon’s behavioral interview is based on Amazon’s 16 leadership principles.
In this round, you’ll be asked questions on workplace conduct and discipline, collaboration, leadership, initiative, and inclusion.
5. The Amazon Bar Raiser Interview
The Bar Raiser round is the final stage of the interview process. It is conducted by a member of Amazon’s Bar Raiser team, i.e., a group of employees specially trained to hire only the best talent.
At the Bar Raiser interview, you’ll be asked questions pertaining to:
- Your prospective role

Amazon QA Engineer Interview Questions on Coding and Analytical Skills
Knowing how to code and approach problem-solving analytically is an essential requirement for QA engineers.
Below are some Amazon QA engineer interview questions on coding asked at the Amazon QA interview. These questions are generally based on coding topics such as arrays, strings, linked lists, graphs, trees, hashing, and other coding concepts on algorithms and data structures.
- Given K sorted arrays ‘arr’, of size N each, merge them into a new sorted array ‘res.’ (Solution)
- Given an array of integers ‘arr’ of size n, which is analogous to a continuous stream of integers input, find K largest elements from a given stream of numbers. (Solution)
- Given an array of integers, find any non-empty subarray whose elements add up to zero. (Solution)
- Find all magic triplets in a given integer array ‘arr’ of size n. A magic triplet is a group of three numbers whose sum is zero. Note that magic triplets may or may not be made of consecutive numbers in arr. (Solution)
- Given an integer, check whether it is a palindrome. (Solution)
- Given an integer n, find all possible ways to position n queens on an n×n chessboard so that no two queens attack each other. (Solution)
- Given the root node of a binary tree T, modify that tree in place, transform it into the mirror image of the initial tree T. (Solution)
- Given a variety of coin types defining a currency system, find the minimum number of coins required to express a given amount of money. Assume an infinite supply of coins of every type. (Solution)
- Given the daily prices of a stock, what’s the maximum possible profit one can generate by first buying one share of that stock on a certain day and then selling that share at least one day later? (Solution)
