The AI Coding Interview: A Complete 2026 Guide
Quick Overview
A practitioner's guide to AI-enabled coding interviews — the format where companies let you use Cursor, Copilot, or Claude Code and evaluate how you direct and verify the AI. Covers the four things interviewers grade (approach, control, verification, communication), the two formats, how to prepare, and which companies use it. Links to real AI coding interview questions on PracHub.
A new kind of coding interview is spreading across the industry. Instead of banning AI, companies now hand you an assistant — Cursor, Copilot, Claude Code, or a model built into the interview platform — and watch how you use it. Meta started rolling this format out in late 2025, and candidates have since reported versions of it at Shopify, Rippling, LinkedIn, Canva, and a growing list of others.
If you're preparing for one, the first thing to understand is that it rewards a different skill than the interviews you've trained for. The people who pass aren't better at prompting. They know what to build, they catch what the AI gets wrong, and they can defend every decision they made. This guide is built around that skill.

What makes this format different
The problems are bigger. A traditional coding interview gives you one function to implement and produces 30 to 50 lines of code. An AI-enabled round often drops you into a multi-file codebase and asks you to fix a bug, add a feature, and then make it scale — hundreds of lines across several files, in one sitting. You don't write all of it by hand, but you're responsible for understanding all of it.
Memorizing algorithms matters less. Reading unfamiliar code quickly matters much more. And there's a dynamic that doesn't exist in a normal interview: you're holding two conversations at once, one with the AI and one with the interviewer. Most people underestimate how awkward that feels until they're doing it under a clock.
What interviewers are actually evaluating
AI makes you feel productive even when you're failing. You paste in the problem, two hundred lines come back, and it looks like progress. But if you didn't plan, can't explain what was generated, and accept everything without checking it, you're failing the interview while the screen fills with code that looks fine.
Across companies, the rubric comes down to four things.
Problem-solving and approach
The fundamentals haven't changed. Interviewers still want to see you understand the problem, break it down, and tackle it in a sensible order. What AI adds is a trap: because the model answers instantly with complete-looking code, it can paper over the fact that you have no plan.
Strong candidates spend the first few minutes reading and forming an approach before they ever open the chat. The common failures: pasting the raw prompt into the AI and building on whatever comes back, following the model into architecture decisions that should be yours, and chasing an AI-suggested rewrite that feels like momentum but is really the model flailing because it doesn't know the answer either.
Control over the AI
Interviewers say a version of the same line: we don't want the AI making decisions, we want to see you make decisions and use the AI to carry them out. You pick the approach. You direct the implementation. If the model is choosing the architecture while you watch, you're already losing points.
A useful test: if you swapped the AI for a junior engineer pairing with you, would you be comfortable with how you're directing them? You're the senior engineer in the room. The AI is a fast, occasionally wrong partner.
Verification
The model will introduce bugs. It will guess wrong about your data model, miss edge cases, and produce code that looks right and isn't. Candidates who accept output without reading it leave a bad impression even when the code happens to work. Good verification means running the code after each meaningful change, reading what was generated to confirm it matches what you asked for, and testing before moving on. The rhythm interviewers want to see is: prompt, review, run, confirm, move on.
Communication
You're managing two conversations, and the AI generates code faster than you can narrate it, so there's a constant pull toward going quiet and just prompting. Resist it. State your intent before you prompt ("I'm going to have it implement the trie, then I'll check the insert logic"). Review the output out loud. Flag anything that looks off. Silence gives the interviewer nothing to evaluate.
The two formats
Most AI-enabled rounds fall into one of two shapes, and they reward slightly different things.
| Format | What you're given | What it tests most | Biggest risk |
|---|---|---|---|
| Build from scratch | A spec for a feature or small app | Designing the structure, then delegating implementation | Letting the AI sprint ahead of your design |
| Existing codebase | Code you didn't write, plus a bug or feature task | Reading unfamiliar code fast, then directing and verifying | Trusting the AI's summary of the code without checking it |
Build from scratch. You're given a spec and asked to build a working feature or small app. Here the risk is letting the AI sprint ahead of your design. Decide the structure first, then delegate pieces.
Work in an existing codebase. You're dropped into code you didn't write and asked to fix a bug or extend a feature. This is the harder, more common format, and it lives or dies on how fast you can read unfamiliar code. The model can summarize the codebase for you, but you still have to build your own mental model and verify the summary.
How to prepare
Practice reading code you didn't write. This is the single highest-leverage thing you can do. Open unfamiliar open-source repositories and trace the class hierarchy, the data models, and the control flow until you can explain them. Tools that summarize repos are fine, but the skill is being able to confirm or correct what they tell you.
Solve hard problems without AI. If you can't solve a problem on your own, you usually can't get the AI to solve it for you either — you won't know when its answer is wrong. Keep grinding medium and hard problems by hand so your own judgment stays sharp.
Practice with a weaker model on purpose. Several candidates have reported the interview AI being noticeably less helpful than the tools they practice with. Build a workflow that assumes the model won't bail you out: you carry the algorithmic thinking, and the AI accelerates the parts you already understand.
Write information-rich prompts. "Fix this" wastes a turn. "Implement a trie with insert and prefix-search, where each node stores a character and an end-of-word flag" gets you usable code on the first try. Tell the model your intended approach and ask it to walk through the complexity before you commit.
Narrate while you work. It feels unnatural at first. Practice talking through your reasoning while you prompt, until the running commentary becomes automatic.
Which companies use AI-enabled coding interviews
Meta is the most prominent — it rolled the format out in October 2025 for software engineering and engineering management roles, and still pairs it with a traditional, AI-free coding round. Candidates have reported similar formats at Shopify, Rippling, LinkedIn, and Canva, and the list keeps growing as more teams decide that interviewing with AI is closer to how their engineers actually work.

Practice
The best preparation is reps on the real format. Drill AI-enabled coding interview questions reported from actual interviews, and pay attention not just to whether you reach a working solution, but to whether you stayed in control, verified the AI's output, and could explain every line. That's what's being graded.
Frequently asked questions
What is an AI coding interview?
An AI-enabled coding interview is a round where you're allowed to use an AI assistant such as Cursor, Copilot, or Claude Code. The problems are larger and usually codebase-based, and interviewers evaluate whether you direct and verify the AI rather than passively accept its output.
How is it different from a normal coding interview?
The problems are bigger (often a multi-file codebase rather than one function), algorithm memorization matters less, reading unfamiliar code matters more, and you manage two conversations at once — one with the AI and one with the interviewer.
Which companies use AI-enabled coding interviews?
Meta rolled out the format in late 2025, and candidates have reported similar rounds at Shopify, Rippling, LinkedIn, and Canva. The list is growing.
How do I prepare for an AI coding interview?
Practice reading unfamiliar codebases quickly, keep solving hard problems by hand so you can spot wrong AI answers, write specific prompts, verify output line by line, and narrate your reasoning. Drill real AI-enabled questions to build the rhythm.
Can I just ask the AI to solve the whole problem?
You can, but it's the fastest way to fail. Interviewers are specifically watching for candidates who prompt their way to a solution they can't explain. The AI is a tool you direct, not the candidate.
