How Codility is built
Codility is built around online coding tests for screening and a live interview environment for later rounds, with a library of tasks across many languages. Engineers often review results or run the live sessions.
Details about other vendors are summarised from their public information and describe their core offering in general terms. Products change, so check the vendor's current offering before you decide.
How SynergicHire is built
SynergicHire runs one role from the apply link to a signed decision. It reads each resume against the role's competencies, screens applicants with an AI interviewer that follows a plan you approve, and runs coding rounds in a Cursor-like IDE with a real AI assistant.
The coding round records how the candidate works with AI: what they typed, what they accepted from the assistant, and whether they tested it. Fundamentals and AI fluency are scored separately, every score cites an answer or an edit, and a named person makes every decision.
Side by side
| Codility | SynergicHire | |
|---|---|---|
| First stage | Online coding test | Resume read against the role, then an AI screen, typed or spoken |
| Later stage | Live interview with an engineer | Coding round in a real project with an AI assistant, reviewed afterwards |
| Engineer time | Engineers typically run live interviews | The AI runs the screen; engineers review cited evidence and sign off |
| Languages | Many languages | JavaScript and TypeScript stacks only |
| After the code | Varies by setup | Hiring manager, HR and panel rounds on one scorecard |
When Codility is the better fit
- You need hands-on tests in languages other than JavaScript and TypeScript.
- Your process centres on live pairing with an engineer and you want a tool for that.
- You rely on ATS integrations.
When SynergicHire is the better fit
- Engineering time is the bottleneck and you want the first conversation handled for every applicant.
- You want to judge AI-assisted work, not only unaided coding.
- You want the whole process, including people rounds, on one record.
Questions
Does an engineer need to attend the SynergicHire coding round?
No. The candidate works on their own in the IDE. The round is recorded as timestamped events, so an engineer reviews it afterwards, with the signals and cited scores beside it.
Does SynergicHire use camera proctoring?
No. There is no camera proctoring and no facial or emotion analysis. Integrity comes from server-side test runs and the record of how the code was written.
Which coding stacks does SynergicHire support?
Coding rounds run React (Vite), Next.js, React Native (Expo) and Node.js projects. Hands-on code in the AI screen is TypeScript. Roles built on other languages can still be screened on concepts, but not with hands-on code.
Does SynergicHire integrate with an ATS?
Not at launch. SynergicHire works as its own minimal applicant tracker: public apply links, a pipeline board, rounds, a scorecard and a recorded decision.
