Stop interviewing
ChatGPT.
Candidates automated the answers. We automated the questions. Fair’s fair. Someone raised $15M to help candidates cheat. We got annoyed and built the other side. We didn’t want to build surveillance. We wanted the guy who pasted the solution to explain it. Turns out that’s the whole product.

Someone on that call
wrote beautiful code.
Maybe even the candidate. One in five admits to using AI in interviews (Blind, 3,617 professionals, 2025). The other four we take on faith.
Nobody gets cuffed here. It asks about the code — authors answer, impostors improvise. The verdict stays yours.
Flawless on the first try
A strong senior and a second monitor write identical code. One of them knows why.
Consistent, which is odd
People pause longer on hard questions. This pause never got the memo.
Your gut isn’t evidence
Confidence sways a debrief. It can’t explain line 26.
Your follow-up questions appear here
Capture the task and the code as it changes. Interview Cop uses that timeline to write questions tied to the solution on screen.
Here’s how it works:
Start a session — capture the technical challenge
Next — keep capturing as code evolves
Run Cop — generate questions from the timeline
Questions land here after each run.
You take screenshots.
It keeps the receipts.
Interview Cop sits at the edge of your screen. Nothing installs on the candidate’s side.
Capture
The task once, then the code at the moments that matter. It remembers so you don’t have to.
Run Cop
Run it when a solution deserves a second look. It reads the timeline, not the candidate’s eyes.
Ask
Read a question out loud. Mark the answer. Your debrief writes itself.
Questions too specific
to bluff through
Select the area
Drag over the function that wrote itself. Yes, that one.
Run Cop
Short questions about decisions the author actually made. You just say them.
Ask and score
Mark right or wrong. It all lands in the debrief.
“You reached for a HashMap in processTransaction. What happens to your lookups when two keys collide?”
Listen for
Chaining or open addressing. Strong candidates also mention lookups degrading toward O(n) when collisions pile up.
Better questions.
Fewer regrets.
It won’t catch everyone. It ends the guessing.
Watch the solution happen, not arrive
The timeline keeps the task, the middle steps, and the final answer. The middle is the part a pasted solution doesn’t have.
Ask about their code, not our trivia
Nobody inverts binary trees on the job. Ask about their own functions, tradeoffs, and edge cases instead.
Your panel stops improvising
It reads the code first, so whoever drew interview duty this week walks in with real questions.
Quiet candidates get a fair shot
A question about their own code lets a quiet candidate prove it’s theirs — out loud, in a minute.
Cheaper than flying candidates in
Google is bringing back in-person interviews over AI cheating (CNBC, 2025). You have options.
Engineering managers
Keep the screen moving
You’re watching code, listening, and taking notes. The follow-up is job four. Delegate it.
Technical interviewers
Ask about real decisions
A question bank doesn’t know what your candidate just wrote. The timeline does.
Talent leads
Debrief with receipts
A bad hire costs about 30% of first-year earnings (US Department of Labor). “Seemed strong” is not a rebuttal.
