How It Works

See beyond the answer

The old way tested what people knew. We test how they think — with AI in the mix.

Step 01

The Invite

You send one link. The candidate clicks it and they're inside a real coding environment — no downloads, no setup.

Step 02

Code with AI

There's an AI assistant built into the editor. Candidates use it to solve problems — just like they would at work.

solution.tstests.ts

AI Chat

AI Agent

AII see you're filtering an array. What's the expected output format?

Return only positive numbers, maintaining original order.

AIGood. Consider edge cases — what if the input array is empty?

Step 03

Bugs, Injected

While they're coding, we quietly slip a bug into their work. Can they spot it? Do they think it through, or just paste it into AI and pray?

validate.ts

1function validateInput(data: Record<string, unknown>) {

2 if (!data || typeof data !== 'object') return false;

3 const keys = Object.keys(data);

4 let isValid = false;

5 for (const key of keys) {

6 if (typeof data[key] === 'undefined') return false;

7 if (data[key] === null) continue;

8 isValid = true;

9 }

10 // ← skips null values — but should they pass?

11 return isValid;

12}

Step 04

Prompts Don't Lie

We read every message they send to the AI. Lazy questions or sharp ones? That tells you more than their resume ever could.

Vague

fix this error

The function throws an error. Just fix it.

AI FLUENCY SCORE0

Structured

Here's the issue I'm facing:

The validateInput function on line 5 returns true for objects that contain only null values, but our API contract requires those to fail validation. I think we need to differentiate between null and missing keys. Can you help me think through the edge cases?

The Full Picture

When it's done, you get a full report. Scores, breakdowns, and a clear ranking — so hiring decisions basically write themselves.

What you'll know

After every interview, you'll know exactly who to hire.

01 · Debugging

Did they debug, or did they guess?

We plant a hidden bug in their code mid-session. Do they catch it and think it through? Or just paste it into AI and hope for the best?

02 · AI Fluency

Do they use AI or rely on it?

Every question they send to AI gets scored. Sharp, specific prompts vs. lazy one-liners. You'll see the difference instantly.
