The Problem

Technical interviews were designed
for a different era.

Engineers ship with AI every day. Most hiring processes still pretend they don’t.

AI changed the job, but not the interview.

Every engineer uses AI to ship — for boilerplate, debugging, architecture decisions. But most assessments either ban AI entirely or can’t measure how it was used. You’re testing for a job that doesn’t exist anymore.

Take-homes don’t scale, and interviewers burn out.

Pairing an engineer with every candidate for hours is the gold standard — but it doesn’t scale. So teams fall back on algorithmic puzzles that tell you nothing about how someone actually builds.

You see the output. You never see the process.

Did they architect the solution or paste it from ChatGPT? Did they iterate thoughtfully or thrash? Today’s assessments give you a score. They don’t give you understanding.

The Platform

See exactly how every candidate builds.

01 — Create Assessment

Connect your repo. Define your rubric. Send a link.

Link your GitHub repo or choose from pre-built templates. Then define custom evaluation criteria with 10+ AI review agents. Invite candidates with a single link.

02 — Candidate Experience

Candidates build on your actual codebase

Candidates get a browser-based IDE with Claude Code on your actual repo — no local setup required. They build, debug, and refactor real code, exactly how they'd work on the job.

03 — Review Results

Know exactly how they built it

Multiple AI agents score every submission against your criteria. See which code was human-written vs AI-generated, replay the full session, and verify understanding through AI-checked debrief questions.
