Using AI in coding interviews is allowed at a growing number of companies (Meta, Google, Microsoft, and Canva among them) and banned at many others. Where it is allowed, you are expected to use it and are scored on how you direct, verify, and own the output. Where it is banned, using a hidden AI assistant is treated as cheating and can get you on a do-not-hire list. The first rule is simple: confirm whether AI is permitted before you touch it.
Can You Use AI in a Coding Interview?
The honest answer is: it depends entirely on the company, and the gap between the two camps is wide. Some employers now insist on it. Canva expects backend, frontend, and ML candidates to use Copilot, Cursor, and Claude. Meta rolled out an AI-assisted coding round in late 2025, Google is piloting one in 2026, and Microsoft candidates now report AI-assisted rounds in SDE loops. Shopify, LinkedIn, and Uber are moving the same direction. Their logic is that engineers use AI daily, so an interview without it tests a skill that no longer exists in isolation.
At the same time, plenty of companies still ban AI in the interview entirely, and getting caught using a covert assistant can end the process and land you on a do-not-hire list. Engineers have started calling this the "AI penalty." So the worst thing you can do is assume. Before an interview, ask the recruiter directly: is an AI assistant allowed in the coding round, and if so, which tool? That one question removes all the risk.
This guide covers both sides: how to use AI well when it is allowed, and how to avoid the penalty when it is not. If you want the format-by-format breakdown of the allowed version, read the AI-assisted coding interview guide next.
Allowed AI Use vs Covert Cheating
| Behavior | Allowed AI Use | Covert Cheating |
|---|---|---|
| Disclosure | Tool is provided or approved up front | Hidden assistant the interviewer cannot see |
| What it signals | Modern workflow fluency | Dishonesty and weak fundamentals |
| How you use it | Direct it, verify it, explain it out loud | Paste the answer and read it back |
| If discovered | Expected, often encouraged | Process ends, possible do-not-hire |
| Skill tested | Judgment and code review | None that the company values |

| Most other companies | Still banned | Covert AI use is treated as cheating; always confirm with your recruiter |
What an AI-Assisted Coding Interview Looks Like
Where AI is allowed, the round itself changes shape. You typically work in a shared environment like CoderPad with a multi-file project tree, a terminal or test runner, and an AI chat panel. The problem is not a blank-page LeetCode puzzle; it is a small but realistic codebase, something like a mini spreadsheet engine or game logic, that you have to read and extend.
A typical 60-minute session moves through four stages: understand the codebase, fix a bug, implement a new feature, then scale or optimize it. Interviewers score how you direct the AI, whether you verify its output, and whether you can explain every line you ship. Some deliberately rely on the model's confident mistakes to see if you catch them. The format rewards the engineer who reads carefully and tests often, not the one who prompts fastest.

Plan First, Prompt Second
Spend the first few minutes understanding the problem and forming a plan. You dictate the steps to the AI, not the other way around. Rushing a prompt before you understand the problem is the most common failure.
Work in Small Iterations
Do not let the AI rewrite large sections at once. Ask for single functions or single files so you can isolate issues and know exactly what changed.
Treat the AI Like a Junior Developer
Give specific, contextual instructions. Instead of "fix the API," say "update fetchUserData in api.ts to return data asynchronously and catch 404 errors." Precise direction is the skill on display.
Critically Review Everything
Read AI output as if a colleague wrote it. Check edge cases, performance, and security, run the tests, and simplify anything overcomplicated. Passively accepting broken code is an instant fail.
Stay in the Conversation
Narrate what you are asking the AI and why. The interviewer is scoring your judgment, and silence while you wait for a generation tells them nothing about your thinking.
How to Use AI During the Coding Interview
Confirm the rules before you start
Ask which tool is allowed and whether AI use is expected. Never open an assistant on assumption.
Scope the problem out loud first
Restate the task, clarify constraints, and sketch an approach before prompting. Your plan should drive the AI.
Prompt for small, specific pieces
Request one function or fix at a time with concrete context, so each change is reviewable.
Review, run, and correct
Read every line, test against edge cases, and fix the model when it is wrong. Catching a real bug live is a strong positive signal.
Explain and own the result
Be ready to justify any line, including generated ones. "The AI wrote it" is never an answer.

Do confirm the policy first
A 10-second question to your recruiter is the difference between an approved tool and the AI penalty.
Do not paste the raw problem and accept the answer
It is the fastest tell that you cannot direct or verify the tool. Interviewers plant bugs specifically to catch this.
Do keep ownership of the design
Let AI handle boilerplate while you keep the architectural decisions, so you can defend them under follow-ups.
Do not go silent while the AI works
Your spoken reasoning is what separates real understanding from lucky generation. Keep narrating.
Do not use AI where it is banned
No shortcut is worth a do-not-hire flag. If AI is not permitted, practice solving cleanly without it.
The Skills That Actually Matter: Ownership and Verification
Strip away the tooling and AI-allowed interviews reward two things above all: ownership and verification. Ownership means you can explain and defend every line in the solution, including the ones the model generated. Verification means you treat AI output as a draft to be checked, not an answer to be trusted, and you catch the confident mistakes the model makes on edge cases, complexity, and security.
These are the same habits good engineers use on the job when they review a pull request or pair with a teammate. That is exactly why companies started testing them. You cannot fake either one by pasting and reading back, which is what makes them the real differentiator in software engineering interviews. Build the underlying problem-solving with coding interview practice, then layer the AI-collaboration habits on top.

Practice this with MockIF →How to Prepare for an AI-Assisted Coding Interview
Confirm your target company format
Ask the recruiter whether the round is AI-assisted, which tool is provided, and whether AI use is expected or optional. Prep for the round you will actually face.
Keep your fundamentals sharp
AI-assisted rounds still test data structures, complexity, and design judgment. You cannot verify code you do not understand, so keep doing regular coding interview practice.
Practice directing an AI in a real editor
Prompting under time pressure is a distinct skill. Rehearse giving small, specific instructions and reviewing the output in a working codebase, not a chat window.
Drill verification until it is a reflex
Practice reading generated code for edge cases, complexity, and planted bugs. Catching a model mistake out loud is one of the strongest signals you can send.
Run timed mock rounds in the format
Do full 60-minute sessions with an interviewer probing your reasoning while you work with the AI. Pressure changes behavior; rehearse under it before the real thing.
How to Practice Using AI in an Interview
Reading the rules is not the same as following them under time pressure with someone watching. MockIF includes an AI-assisted coding round built for exactly this: you work in a real in-browser editor with an in-editor AI assistant while a voice AI interviewer probes your reasoning and scores how you collaborate with the model. It grades the things that matter here: whether you plan before prompting, whether you verify output, whether you catch the model's mistakes, and whether you can own every line.
It sits alongside a debugging round and an algorithm-and-practical round that runs your code against real tests, so you can rehearse whatever your target company throws at you. Sessions support Python and TypeScript and cost 2 credits each. When you want the full breakdown of the allowed format and what it scores, read the companion guide on the AI-assisted coding interview, then come back and practice the rules until they are automatic.
