Hire engineers who can think.
AI allowed and logged · 90-minute screens · Pay per screen, no seats
The signals you used to trust are gone.
Resume, take-home, timed round: one open browser tab clears all three. So you advance people on borrowed signal, and a wrong senior hire still costs six figures.
The question worth asking is whether they can tell when AI is about to walk them off a cliff.
What AI already does for them
What it can't do for them
Own a real problem under pressure, push back on a bad spec, and catch the bug the model swore wasn't there.
Take the screen yourself
Here's a real PR. See what you catch.
Click any line you'd comment on, then submit. We'll line you up against a top-decile candidate and an AI reviewing cold. About thirty seconds.
- · Look at where the data comes from
- · Think about two requests at once
- · Not every ugly line is a bug
0 lines flagged
Your review
Top candidates leave three to five meaningful comments. There are deliberate red herrings in the diff; flag one and it costs you.
One outright security hole, one concurrency bug, one smaller correctness issue. Go find them.
How it runs
Four steps, and almost none of them are yours.
Set up the screen
Pick a role preset, nudge a few sliders, add any hard requirements. Five minutes.
Send one link
Drop in emails or share one invite URL. No account for them to create.
They work, you don’t
A real PR, a live bug, and a judgment call. AI is on, every keystroke is logged.
Read the report
A composite score, a five-axis breakdown, and the moments that mattered. Ten-minute call.
Good engineers were never the ones who typed the fastest.
Interviews rewarded speed, recall, and a tolerance for unpaid take-homes. None of it was the job, and all of it is now free from a model.
Judgment is what moves your roadmap: knowing what's worth building, and catching the confident answer that's wrong. AI doesn't have judgment. It borrows yours.
So we hand a candidate a real problem with AI switched on, and grade the decisions they make. Everything else was noise.
Find the cracked ones.
Interactive · live scoring
One answer. Score it against your team, not a generic rubric.
Drag the dials to match how your team works. The same answer gets re-scored live, because a response that fits a ship-fast team is wrong for one that gates every deploy.
Your team's style
“Looks good. Two concerns: (1)..., (2)..., Tradeoffs OK if [...].”
“"I’m not convinced this approach holds at scale. My reasoning:"”
“Short summary + tests mentioned.”
“"Behind a flag with a rollback plan."”
“Pair-programs with AI; accepts ~50%; drives high-level decisions.”
Candidate response
Looks solid overall. Two concerns: (1) `user_id` comes from query params, which is an auth bypass; it should come from the session/JWT. (2) The favorites fetch is going to N+1 at scale, a JOIN would fix it. Otherwise good. Happy to walk through alternatives if helpful.
Style match
Strong fit
Cultural fit is one axis among five, capped at 10% of the composite, so it never overrules technical signal.
What you get back
A report you can decide from in ten minutes.
One composite score with a confidence read, a five-axis breakdown, and the few moments that moved it. Each one is timestamped to the replay, and the whole thing fits on a page.
