Learn more about our library question development and content validity process
HackerRank library questions are developed by an internal team of item writing and content experts. HackerRank content writers adhere to specific guidelines when drafting test questions. Test questions are drafted, reviewed, and revised as necessary and reviewed again.
In addition, test questions are field tested to ensure they function as intended. This rigorous process of item development ensures the items in our library are valid, that is, they measure the knowledge or skills they are intended to measure and none other.
