Live IDE + Video, perfectly synced

Candidates code in a production-like IDE while you watch in real time. Capture first-run, test cadence, and the actual path they take to a working system.

const run = async () => {

const res = await api.test();

console.log(res.ok);

}

AI interviewer = consistent signal

A calibrated AI PM handles clarifications and constraints. Every candidate gets the same prompts and the same rigor—so your panel compares apples to apples.

Can you clarify pagination and idempotency?

Use key-set pagination; make retries idempotent with a token.

Automated analysis for the panel

We summarize decision quality, debugging patterns, and system maturity. Plus full replay for calibration and debriefs—so you can hire with confidence.

Watch candidates code in real-time

An IDE embedded next to video—no tab juggling, no environment drift. You see edits, test runs, and the exact decision points that led to the final code. Capture first-run times, revert behavior, and how quickly they converge on a stable design.

AI interviewer handles the questions

A calibrated AI PM answers clarifying questions, repeats constraints consistently, and keeps the candidate on specification. That means reduced bias, perfectly repeatable interviews, and cleaner signals for the panel.

Can you clarify pagination and idempotency?

Use key-set pagination; make retries idempotent with a token.

Real signals, not just gut feelings

We score execution patterns, not personality. Signals include decision quality (trade-off clarity, error budgeting), debugging efficacy (time-to-root-cause, corrective actions), and system maturity (idempotency, failure modes, data integrity).

Interview Process

1
MVP Phase
0–30 min
Ship something runnable. Prioritize external contracts & tests.
2
Scale Phase
30–60 min
Add throughput. Remove hotspots. Prove idempotency & backpressure.
3
Hardening
60–75 min
Failure modes, retries, budgets. Observability & guardrails.
4
Debrief
75–90 min
Reason about trade-offs. Walk through alternatives and debts.

const run = async () => {

const res = await api.test();

console.log(res.ok);
