Types of coding assessment
| Type | Measures | Watch out for |
|---|---|---|
| Timed algorithm problems | Problem solving under time pressure | Little resemblance to daily work; easily answered by AI |
| Take-home project | Realistic building | Length for candidates; unknown authorship |
| Live coding interview | Reasoning out loud | Engineer time; nerves |
| AI-assisted coding round | Building with an assistant, and checking it | Needs event capture to separate candidate from AI |
Why AI changes coding assessments
If the job allows an assistant, a test that bans one measures the wrong thing, and a test that ignores one cannot tell who wrote the answer. A modern assessment either controls the assistant deliberately or records how it was used.
How to choose
- Match the stack to the role: a React role gets a React project.
- Use starter files and tests so candidates spend time on the problem, not setup.
- Decide how much AI help is allowed, and enforce it.
- Run tests where you can trust them, not in the candidate's browser.
How SynergicHire assesses code
Coding rounds run React (Vite), Next.js, React Native (Expo) or Node.js projects in a sandbox with Monaco, a terminal, tests and a live preview. Guarded mode tests fundamentals with a limited helper; unguarded mode gives a full assistant. The server enforces the mode. Code is tinted by who wrote it, the six AI-fluency signals update during the session, and the server reruns the tests at the end.
Questions
Which languages does SynergicHire's coding round support?
JavaScript and TypeScript projects: React (Vite), Next.js, React Native (Expo) and Node.js. Code in the AI screen is TypeScript.
How long is a SynergicHire coding round?
You set the length; the price covers rounds of up to 90 minutes.
Can candidates cheat a coding assessment with AI?
If the assistant is part of the assessment and its use is recorded, using it is not cheating. It is what is being measured.
