The interview you cannot cheat,because using AI is the test.
Candidates solve a real ticket with an AI coding agent. Assay records every prompt and every diff, then interviews them on the work they just did.
The problem
Why the interview broke
The tools changed overnight. The interview stayed in 2012.

Rise in candidate cheating (H2 2025)
Rise in reported candidate cheating over the second half of 2025. Overlay tools now render below the layer screen sharing captures, feeding candidates answers in real time.
91%
Of engineers use AI coding agents at work
Most technical screens still ask candidates to invert a binary tree alone, with no internet and no tools, on a sterile virtual whiteboard. It tests what they do not do at work.
Applicants per open role in India have more than doubled since 2022. Companies are not short of candidates. They are short of a way to tell them apart.
The difference
Everyone else tries to catch AI. Assay hands it over.
Detection is an arms race against software that draws below the layer screen sharing captures. Assay does not enter it.
A usual technical screen
The tools
- AI is banned, then policed with proctoring.
- Overlay tools render below the layer screen sharing captures.
The test
- An algorithm, alone, from memory.
- Nothing like the work the job actually involves.
The cost
- A senior engineer in the room for every first round.
- Most of those hours go to people who were never going to make it.
The result
- A number you are asked to trust.
An assay
The tools
- The candidate is handed an AI coding agent and told to use it.
- Every prompt, diff and test run is recorded in order.
The test
- A real ticket in a seeded repository.
- Questions generated from the diff they wrote minutes earlier.
- Nothing to buy: those questions existed nowhere until they wrote it.
The cost
- Nobody in the room. The interrogation runs itself.
- Your engineers meet the shortlist, not the queue.
The result
- Every score opens onto the quote, timestamp or diff behind it.
- Assay recommends. A person decides.
The session
How a session works
Real ticket
A seeded repository and a real ticket. Sometimes a bug, sometimes a spec with a deliberate ambiguity in it.
Agent-enabled work
The candidate uses an AI coding agent. Every prompt, diff and test run is recorded in order.
The interrogation
Assay asks about their own diff, by voice, seconds after they finish. Not general questions. Their questions.
The report
Every score expands to the exact line, timestamp or diff that produced it.
The report
Every score points at the moment that produced it.
Assay never hands you a number and asks you to trust it. Open any score and you get the exact answer, timestamp or diff hunk behind it. The report is built to be argued with.
- 1
The overall recommendation
One line, with the reasoning attached. Never a number on its own.
- 2
Scored competencies
Each one out of 100, and each one opens onto what earned it.
- 3
The evidence behind every score
Timestamps, direct quotes, reasoning and diff hunks, one click from any score.

We are onboarding a small number of teams to run real candidates.
The limits
What Assay does not do
It recommends, and a person decides.
Who it is for
Built for teams without a spare senior engineer.
For companies where a first‑round technical screen costs a senior engineer an hour per candidate, and most of those hours go to people who were never going to make it.

This year
Google, Meta and Canva all moved to AI‑assisted interviews. All of their versions need a senior engineer in the room.
This one does not.
