How are assessments graded?

Each question runs the candidate code against your test cases and scores it automatically. You can weight questions by points, so harder problems count for more, and every candidate gets one clear weighted score.

Can I reuse questions across assessments?

Yes. Questions live in a shared library, so you build them once and add them to any assessment. You can also see how each question performs over time to keep the ones that work.

What languages are supported?

Candidates can solve assessments in 20+ languages, and their code is graded automatically in the language they choose.

Can candidates cheat?

You can mark test cases as hidden so candidates cannot simply hardcode the expected output. You see exactly which visible and hidden tests passed.

Do candidates need an account?

No. You invite a candidate by email and they open a link to start. There is nothing for them to install or sign up for.

Screen smarter, not harder

Coding assessments that grade themselves

Send candidates a real coding challenge, get back scored results, and only spend live-interview time on the people who can actually code.

Why teams screen with CoderScreen

Auto-graded

Candidates solve real problems checked against your test cases. Scoring is automatic, so there is no rubric to argue over.

Real coding, not trivia

Skip the multiple-choice quizzes. Candidates write actual code in the language they would use on the job.

Candidate-friendly

A clean editor, clear instructions, and no account to create. Candidates just open a link and start.

Fewer wasted interviews

Filter your pipeline before anyone gets on a call. Your team spends its time on the strongest candidates.

Hidden test cases

Keep some tests private so candidates cannot hardcode the answers. You see exactly what passed and what did not.

Open source

CoderScreen is fully open source. Inspect the code, self-host, or contribute.

Everything you need to screen at scale

A reusable question library

Build your coding questions once and drop them into any assessment. See how each question performs over time so you keep the ones that actually tell candidates apart.
