Most Common OA Topics
Amazon OA Format and Platform
The Amazon online assessment is delivered through a proctored online platform, most commonly HackerRank. Candidates receive the OA link by email after passing an initial resume review. The coding section typically contains 2 to 3 algorithmic problems with a 70 to 110 minute time limit.
Some Amazon teams include an additional work simulation section that tests judgment and decision-making rather than coding ability. This section is not present for all roles. Check the LeakCode question database filtered by role type to see what past candidates for your specific role reported.
FAQ
Does Amazon have an online assessment?
Yes. Amazon uses an OA as the first technical screen for most engineering and technical roles. It is typically sent after a resume review and before any human interviews. The format has remained consistent across recent hiring cycles.
How hard is the Amazon OA?
Based on candidate reports, Amazon OA problems range from LeetCode medium to hard. Expect at least one problem that requires an efficient algorithm (not brute force) to pass all test cases within the time limit.
Where do these OA questions come from?
All questions in the LeakCode database are sourced from actual candidate reports on 1Point3Acres, Blind, Glassdoor, Reddit, and LeetCode. They are not AI-generated. Each question links to its source where the original report is public.
