Choose the market leader in developer skills assessment. Explore why thousands of engineering teams switch to HackerRank each year.
HackerRank is the only developer‑skills platform that delivers deep skill coverage and built‑in integrity signals, so every assessment is both predictive and trustworthy.
HackerRank offers unmatched breadth and depth with over 7,500 questions covering 260 skills and 84 roles. We go beyond the simple question types offered by our competitors with advanced Code Repo questions that simulate the real work developers do every day.
AI is built in throughout HackerRank's product stack, from integrity monitoring and AI proctoring to a modern AI-assisted IDE and an AI interviewer. While competitors treat AI as a gimmick, HackerRank is leading the way with an AI-first platform that truly supports the modern hiring process.
HackerRank’s Integrity Signals combine AI plagiarism‑detection, tab‑proctoring, monitor detection, ID verification and full session replay—surfacing a single, easy‑to‑read integrity score after every test or live interview. None of our competitors provide a consolidated, multi‑signal integrity score, leaving hiring teams to guess whether a candidate was truly unaided.
"HackerRank’s built‑in Integrity Signals let us trust every score, and the question library is miles ahead of Codility and CodeSignal. We reduced bad technical hires by 40% in the first quarter."
Take-home assessments that ensure fairness and integrity.
Identify strong developers by administering a take-home assessment in a secure environment. Choose from a library of thousands of challenges across many roles designed by experts and validated by Industrial Psychologists for fairness.
Get an accurate sense for what it would be like to work together by pair programming with candidates on real-world scenarios. Review code, fix bugs, build a feature, and see the result, all within an interview setting using pre-set repos or one of your own.
