Guide for hiring teams

How to run technical interviews when candidates use AI.

Let candidates use AI under clear rules you state up front, give them realistic engineering work instead of puzzles, and review how they got to the result: whether they directed the AI with clear constraints, caught incorrect or incomplete output, verified the work with tests, and can explain what they chose to ship. Keep the hiring decision with people.

Six steps

From AI rules to a hiring decision

1.State the AI rules before the interview

Decide whether AI is allowed for this role and this task, which assistants candidates may use, and what is recorded. Tell candidates in the invitation, not at the start of the session.

Clear rules remove the guesswork that makes candidates nervous and makes results hard to compare. When everyone works under the same conditions, the evidence means the same thing for each person.

2.Use realistic work instead of puzzles

Modern engineers use AI, so a puzzle an assistant can solve in seconds tells you little. Give candidates the kind of work the job involves: a small service with tests and logs, a bug to fix without hiding failures, or a change to review.

Set a time box and ask for an output you can review, such as a patch plus a short decision note explaining what they changed and why.

3.Evaluate judgment, not just a passing result

Access is not the compromise. Uncritical use is the risk. The useful signal is whether a candidate can direct AI, question it, verify it, and take responsibility for what ships.

  • Direct AI with clear constraints
  • Catch incorrect or incomplete output
  • Challenge assumptions and tradeoffs
  • Verify generated work with evidence
  • Decide what is safe to ship

4.Collect evidence your team can review

A single score hides how the work was done. Keep the code, the tests, the prompts, a replay of the session, and the candidate’s own explanation together so reviewers can check the reasoning, not just the outcome.

Treat integrity events, such as unusual pasting or leaving the tab, as context for a reviewer to investigate, never as a cheating verdict on their own.

5.Follow up live where the evidence is thin

Use a short live interview to explore the parts of the take-home work that were unclear: a decision that was not explained, a test that was skipped, or an AI suggestion that was accepted without checking.

A focused follow-up is quicker than repeating the whole assessment, and it gives candidates a chance to show depth.

6.Keep people accountable for the decision

Assessment evidence is one reviewable input, not a complete verdict on an engineer. Your team reviews the work, decides who advances, and communicates the outcome.

Common questions

Should candidates be allowed to use AI in technical interviews?
For most engineering roles, yes, under clear rules stated in advance. Engineers use AI at work, so the useful signal is whether a candidate directs it well, catches its mistakes, and verifies the result, not whether they can work without it.
How do you stop candidates from cheating with AI?
Make AI use part of the rules instead of something to hide, use realistic work that rewards judgment over recall, and review the process as well as the result. Treat integrity events as context for a reviewer to investigate, not as automatic verdicts.
What should you evaluate when candidates use AI?
Whether they direct AI with clear constraints, catch incorrect or incomplete output, challenge assumptions and tradeoffs, verify generated work with evidence, and decide what is safe to ship.
Do take-home assessments still work when candidates have AI?
Yes, when the task is realistic, the AI rules are explicit, and the team reviews evidence such as code, tests, prompts, and the candidate’s explanation, followed by a short live interview where the evidence is thin.
