Overview
The HackerRank Library is a repository of all the questions that can be used to create Tests. The Library contains a collection of readymade Questions of various types and complexities, which are categorized across multiple programming languages. The HackerRank Team has bundled these Questions together, which you can use to build Tests and assess your Candidates' skills relevant for specific job Roles.
Additionally, for custom requirements, you can create new Questions in HackerRank and store them in a personal section called 'My Company questions' within the Library. You can manage your Questions and use Questions created by other HackerRank Team members.
