HackerRank (formerly Interviewstreet) provides a platform for screening technical candidates with programming challenges.

Resumes, GPA, education and work experience don't paint the full picture of a job applicant. By using the HackerRankX platform, customers can administer coding challenges to applicants during the hiring process and gain an objective metric that saves hiring managers and recruiters time and dollars.

The HackerRankX platform is used by more than 1,000 companies, and its rapidly-growing customer base includes top tech companies such as Facebook, Yahoo, Amazon, Microsoft, Quora, Skype and Evernote.
