Coding assessment for hiring developers
A coding assessment shows what a developer can actually build. DeveloperHiring gives each candidate a realistic task in a browser editor with 30+ languages, runs hidden tests in a sandbox, records integrity signals and scores every submission on the same rubric.
What makes a good coding assessment?
A good test looks like the real job. Puzzles reward people who practiced puzzles. A realistic task, like building a small API or fixing a bug in existing code, rewards people who can do the work you are hiring for.
- Realistic. Tasks mirror day-to-day work for the stack and seniority.
- Objective. Hidden tests decide correctness, not a reviewer's mood.
- Short enough. Most tasks take 60 to 90 minutes, so strong candidates do not drop out.
- Explained. Candidates see the rules, the time limit and what is recorded before they start.

Pick the format per role. All formats use the same sandbox, scoring and integrity signals.
| Format | Best for | Typical length | Plans |
|---|---|---|---|
| Timed task | Fair comparison of many candidates | 60 to 90 minutes | All plans |
| Take-home | Senior roles and design depth | Up to 72 hours to submit | All plans |
| Library task | Common stacks and seniority levels | Ready to send | All plans |
| Custom task | Your own codebase style and domain | You choose | Team and Scale |
| Live coding room | Pair programming with your team | 30 to 60 minutes | Team and Scale |
| Assessments API | Sending tests from your own product | Any | Scale |

Signals inform your team. They never reject a candidate on their own.
How do you stop cheating in remote coding tests?
AI tools made take-home tests easy to fake. We do not try to ban every tool. We collect signals and then ask about the work, which is much harder to fake.
- Paste events and tab switches, with timing.
- Keystroke playback, so you can watch the solution being written.
- Code similarity across every candidate of the same role.
- A likelihood score for AI-generated code.
- Optional webcam snapshots, only with the candidate's consent.
- An identity check on Scale, comparing a document with a selfie.
Then the AI technical interview asks about the candidate's own code. Signals never reject anyone on their own. Your team reviews and decides.
Which languages and stacks are covered?
The editor supports 30+ languages. Library tasks exist for the stacks teams hire for most.
Each stack page shows the skills we test, sample screening questions and an outline of the coding task, for example how to hire Java developers or hire Golang developers.
How much do coding assessments cost?
Many assessment tools sell invites or attempts as credits. DeveloperHiring includes assessments in a flat monthly plan, together with sourcing, interviews and the shortlist.
