AI can write the code. Hire the people who steer it.
Technical tests built on real work scenarios, with AI scoring, camera proctoring and verified identity. You see how someone thinks, not just whether the code passed.

What matters when AI codes too
Passing the test got easy. What separates candidates now is reasoning, mature use of AI, and proof that whoever took the test is who shows up to work.
Reasoning tested on real work
Problems pulled from the job itself: fix a bug in legacy code, review a pull request, model data. Not interview puzzles.
AI fluency actually measured
Scenarios that check whether someone uses AI with judgment: validating output, understanding what was generated, knowing when to push back.
The person who tests is the person who signs
Identity verified with deepfake detection, camera proctoring and every step recorded. The result holds because the person is real.
A report that decides, not just describes
When the test ends, each candidate becomes a single page: score per skill, evidence of what they did, and a recommendation from the agent. No spreadsheets, no guesswork.
- Score per skill, weighted the way you defined for the role
- Code snippets, time per question and the path to the solution
- Integrity signals: identity, camera, tab switching and pasting
- Comparison against the role average and your own benchmark
- A recommendation from the decision agent, with the final call always human

What sets Workdex apart
Technical assessment is the means, not the end. What we deliver is a decision backed by evidence.
A test built in minutes
Describe the role and the agent suggests skills, weights and questions. You adjust and publish the same day.
AI scoring with an open rubric
AI grades open questions and code against the rubric you can see. No scores nobody can explain.
Calibrated on data
Over 1 million people assessed back the bar. Compare a candidate against the market and against your own team.
A library of real scenarios
8,000+ ready assessments and templates, or your own questions built in the editor. Content keeps up with your stack.
Fits the way you already hire
10+ ATS integrations, plus API and MCP support. Tests fire from wherever your process already lives.
An experience candidates accept
Runs in the browser, no install, with a decent editor and autocomplete. Less drop-off mid-funnel.
Results that survive an audit
Fraud in technical hiring is routine now. Every layer below exists so the result still means something.
Identity and anti-deepfake
Identity verified up front and checked continuously through the test and interview, with synthetic video detection.
AI-analyzed proctoring
Camera, screen, second screen, tab switching and pasting all monitored. Signals become flags, not automatic accusations.
Complete evidence trail
Every step recorded with the candidate's explicit consent, aligned with GDPR and local data protection law.
How it works, end to end
Four steps between opening a role and having verified candidates in front of you.
Describe the role
The agent turns your description into skills, weights and a suggested test at the right seniority.
Publish and invite
Invitations go out from your ATS or from Workdex, with identity verification right at the door.
Candidates do real work
A proctored test in the browser, built on scenarios that look like the actual job.
You decide with evidence
A report per candidate, ranking by job fit and the agent's recommendation. The final call is always yours.
Ready for large operations
What compliance and engineering usually ask, answered up front.
Frequently asked questions about technical assessments
What is a tech assessment and when is it worth using?
It is a technical evaluation run before final interviews to measure demonstrated skill rather than claimed skill. It is worth it whenever candidate volume is high or the resume no longer differentiates, which today is nearly every technical role.
Can candidates use AI during the test?
Your call. You can block and monitor AI use, or do the opposite: allow it and assess exactly how critically they use it, with scenarios where the model output is wrong on purpose.
How do you prevent cheating and proxy candidates?
Identity verification with deepfake detection, AI-analyzed camera proctoring, and monitoring of screen, second screen, tab switching and pasting. Every signal is stored as evidence.
Does the test only cover programming?
No. We cover engineering, data, infrastructure, AI, security and architecture, including code review, technical decision-making and communication, which weigh most at senior levels.
Can we create assessments for our own roles?
Yes. Use the catalog of 8,000+ assessments and templates, adapt an existing scenario, or write your own questions. The agent helps assemble the test from the job description.
How fast can we go live?
The first test can go out the same day. Describe the role, review what the agent suggested and start inviting candidates. ATS integration usually lands in the same week.
Does it integrate with our ATS?
Yes. There are 10+ ready integrations, plus a full API and MCP support for in-house systems. Tests fire and results return inside your existing flow.
How is pricing structured?
Pricing follows the volume of candidates assessed and the modules you use. Talk to a specialist to get a proposal calculated for your operation.
