AI-Assisted Coding Interviews

What each company actually asks, from real candidate reports

Through 2026, many companies replaced a coding round with one where you work alongside an AI assistant. Most advice about it is generic. This page goes company by company: the platform, the questions candidates got, what interviewers said they grade, and why people who got the code working still failed.

Key facts

  • •In 2026, Meta, LinkedIn, Rippling, Snowflake, Stripe, Amazon, Capital One, Zip, Instacart, Microsoft and others added an AI-assisted coding round, or replaced a coding round with one.
  • •Usually one problem in several parts, on an existing codebase with tests, in about 45 to 60 minutes. You are not told how many parts there are.
  • •Graded on your own plan, how you direct the AI, whether you verify its code, and how well you explain it, not just on finishing.
  • •The most common reasons for rejection: running out of time before the later parts, failing a large-input part, and pasting the whole problem into the AI.
  • •Compiled from 34 candidate reports posted April to October 2026, plus the reports behind our company guides · last updated October 2026.

Three shapes of the round

Algorithm in a codebase

A prepared repo with tests and a problem that escalates part by part, often ending in a large-input test. Meta, LinkedIn, Snowflake.

Build a working thing

A small service, engine or agent from a starter file, in your own IDE with your own assistant. Rippling, Cresta, Persona, Ramp, Harvey.

Debug, then extend

An existing app with bugs: fix them, then add a feature, then explain what the AI changed. Zip, Capital One, Instacart, Amazon's OA.

How interviewers say they grade it

Reports agree on one point: the plan has to be yours. A commenter who said they were a LinkedIn interviewer described the training as looking for prompts that show you digested the problem and picked the data structure and algorithm yourself. A Snowflake interviewer told a candidate they watch how you ask the AI, how you write prompts and how you judge tradeoffs. The Rippling candidate who passed wrote the classes and skeletons themselves and only then handed functions to the AI.

The other half is explaining the AI’s code. Meta asks for the algorithm after every part, Zip picks functions the AI wrote and asks how you would optimize them, and Datadog wants to hear what the AI did. Several candidates also say the bar depends heavily on the interviewer, and that many interviewers are still unsure what to look for.

Why people fail it

Running out of parts

Most rounds are one problem that keeps growing, and you are not told how many parts there are. Finishing two of four is a common rejection. One candidate spent twenty minutes reading a long problem and confirming twenty open questions the AI raised, which left ten minutes to build.

The hidden scale part

The assistant solves the small case with whatever comes to mind first. The round really starts when the interviewer hands you the large input. Ask early what the data sizes will be.

Pasting the problem in

Candidates and one self-described interviewer say pasting the whole problem into the chat is close to an automatic fail. A Scale AI candidate was stopped from pasting a screenshot. An Additive AI candidate who handed over the requirements wholesale sensed the interviewer did not like it.

Finishing too fast

When the AI solves it in five minutes, some interviewers run out of things to evaluate. A candidate in that position recommends slowing down and talking through why the code is written that way and what the tradeoffs are.

Misreading the requirement

One rejected candidate filtered logs by matching the word WARN, when the task meant WARN and everything more severe. The code ran and the output looked right. Restate the requirement in your own words before you prompt.

Fighting a weak tool

Built-in assistants are reported as slow on CoderPad and CodeSignal, unable to edit code on Karat, and inconsistent from one answer to the next. Several candidates say typing it themselves would have been faster.

Company by company

Meta AI coding interview

Onsite · CoderPad with a built-in assistant

Meta calls it AI-native coding. Reports describe two such rounds in the onsite, next to one or two AI-enabled system design rounds and a behavioral round. The phone screen is still two LeetCode-style problems without AI.

You get a folder of existing code with tests already written, and a chat panel where you can pick the model. Candidates name Claude Opus and GPT models. One candidate notes the available models lag public releases by a month or two. The work comes as a single problem in several parts, and after each part the interviewer asks you to explain the algorithm the AI wrote.

Reported questions: a maze solver in four or five parts (fix a display bug, fix a search that never terminates, add tiles that force a direction, add keys and doors, which means the visited state has to include the keys you hold, then a bomb that clears walls); the largest set of words with no repeated letters, first on about a dozen words and then on tens of thousands; friend recommendation, from fixing a validity check to designing a strategy that runs on about 100,000 users and 1.5 million friendships; a card game where you repeatedly pick three cards summing to 15 and must benchmark your strategy over a thousand games; a pathfinding problem; and speeding up a brute-force search for one string inside another.

The pattern that sinks people: the last part is a scale test. One candidate's solution passed on the small map, then the interviewer opened a very large input and it timed out, and the rest of the round went to arguing with the assistant. Another measured the sandbox at about 1.5 CPU cores and 2 GB of memory, and warns that a modern assistant will run the big test on its own unless told not to.

LinkedIn AI coding interview

Virtual onsite · CoderPad, choice of GPT, Gemini or Claude

The rules here are the strictest reported. Both the recruiter and the interviewer told one candidate the algorithm must be theirs and the AI may only help implement it.

The reported question is an LRU cache in four parts: plain LRU, then a TTL, a third part the candidate did not recall, then thread safety. The candidate designed the hashmap plus doubly linked list, then spent the round correcting the assistant, which forgot to remove evicted keys from the map and invented variables. They finished two of four parts, and the feedback named this round.

A commenter who said they were a LinkedIn interviewer described the training: they look for prompts that show you digested the problem and chose the data structure and algorithm yourself, then used the AI to write more code than a normal round allows and to help review it. A stronger model is not the point.

Rippling AI coding interview

Phone screen · your own IDE and AI, tests run on HackerRank

Rippling's phone screen is now reported as an AI coding round of about 60 minutes. One candidate was told it could not be opted out of. You set up your own IDE and assistant beforehand. In one report you copy a single starter file into it and paste the result back into HackerRank to run the tests.

The questions are the ones already in Rippling's catalog: the expense rules engine, the task manager, the delivery driver payment system, and the card-hand problem. A rate limiter is also reported.

The reports disagree on pace, and that is the lesson. The candidate who passed kept the AI closed for about twenty minutes, talking the design through with the interviewer and typing the structure by hand, and only then asked it for function bodies. A candidate who solved a rate limiter with Cursor in a few minutes was left with an interviewer who had nothing more to ask, and was rejected the next day. Interviewers ask about complexity and why you designed it that way.

Snowflake AI coding interview

Onsite, in person · CoderPad assistant, three models

An entry-level candidate had AI coding, behavioral and system design back to back in one room. The AI coding task was a task queue: a worker pulls jobs, retries with exponential backoff (the interviewer wanted jitter and a cap), and sends jobs past the retry limit to a dead-letter queue. A follow-up added job priority, and the discussion was one priority queue against one queue per level, including how the client input differs.

The interviewer said afterwards what they grade: how you ask the AI, how you write prompts, and how you judge the tradeoffs. Even when the candidate already had a solution, the interviewer pushed them to ask the AI for alternatives. The built-in assistant took minutes per answer. Snowflake also runs a separate 20-to-30-minute screen where an AI asks behavioral questions.

Capital One AI coding interview

TDP Power Day · Claude allowed

The Power Day is three rounds: behavioral, a case study, and agentic coding. The agentic round gives you a full-stack app (React and Vite in front, Python and FastAPI behind). You find and fix its bugs, then build a new feature, using Claude to locate and explain code while showing you understand each change.

The case study in the same report is a chatbot: the business benefit first, then explaining and improving a piece of code, then talking through how new requirements would change it. No code is written in that round.

Zip AI coding interview

Onsite · existing codebase, AI reads and writes

A new onsite round in three parts on an expense and budget-report codebase too large to read by hand. Part one: monthly reports are wrong because some expenses are filed in a later month than they happened; debug it. Part two: add a report feature until the tests pass. Part three: brainstorm what production would need and have the AI build it. The follow-up picks functions the AI wrote and asks whether you understand them and how you would optimize them.

Zip interview guide →

Cresta AI coding interview

Onsite · your own IDE, Python

Two reported tasks. One gives you an API document and an agent starter script, plus an LLM key and an API key, and asks you to build a chat agent that saves passenger details, searches flights and books one through tool calls.

The other is a feature-flag evaluator: flag definitions, ten thousand users and a file of expected decisions for 200 of them. The traps are in the data: a disabled flag returns its default, regular expressions only match from the start, some rules roll out to a percentage of users, two rules can match the same user, and some user fields were blanked after the expected answers were generated. The candidate's advice is to reverse-engineer the expected file before writing the engine.

Persona AI coding interview

Technical screen · CodeSignal's built-in Claude terminal

60 minutes to build an internal go-link tool for about 100 users. Part one: create a short link and redirect on visit, in memory. Part two: login, link ownership (anyone can see links, only owners can delete), and analytics on the most-visited links and links per user. The candidate says the interviewer grades how you scope the work, direct the AI and verify its output. The assistant was throttled and slow, they ran out of time, and they were rejected.

Instacart AI coding interview

Full-stack assessment · CodeSignal, Claude Code

Five tasks in 90 minutes, with a live preview of the web app. Two tasks are a chat with an AI that hands you the requirements, two are building them with Claude Code, and one is a bug fix without AI. The first build adds search and filtering. The second is much longer: a notification service with in-app availability alerts and due-date reminders, with idempotency and async edge cases. A score of 650 out of 1000 was a rejection.

Ramp AI coding interview

Onsite · $50 stipend for your own AI tools

Ramp gives you a repository and a $50 stipend to set up whatever AI tools you want, then asks you to build a matching system in any language. If you finish the core, you pick bonus tasks.

Stripe AI coding interview

Onsite programming round or screen · HackerRank assistant

From 2026, several Stripe reports describe the programming round, and on some loops the screen, as an AI coding round using HackerRank's built-in assistant. The transaction rule parser is the reported question. Candidates who did well formed their own plan before prompting, read the assistant's code closely and added their own tests.

Amazon AI coding interview

Online assessment · AI that points but does not write

Since January 2026 the Amazon OA often pairs an algorithm problem with about 60 minutes of debugging an existing repository. The assistant will point you at files but will not write the fix. Reproduce from the README and read the failing tests before changing code.

Amazon interview guide →

Anthropic AI coding interview

Two different rounds

Anthropic runs a build-an-agent round, where you write the agent loop yourself, and a separate AI-assisted round where you use Claude Code to review and fix pull requests in an unfamiliar repository. A recent onsite report describes an AI round that starts from fixing a bug.

Anthropic agent coding guide →

Datadog AI coding interview

Any AI coding tool

Write a client that submits a query to Snowflake's API and polls its status. The follow-up asks what to do when the result is very large. The candidate, who was rejected, says Datadog expects every follow-up answered and wants you to explain what the AI did.

Microsoft AI coding interview

Onsite · your own IDE with an AI agent

The invitation names two rounds, AI Coding Agent for coding, algorithms and debugging, and AI Coding Agent usage best practices, and asks for an IDE connected to a coding agent, with VS Code recommended. The candidate who reported back got two ordinary LeetCode problems, where using AI for tests was optional. Standards seem to vary by team.

Harvey AI coding interview

Onsite · your own IDE and AI tool

Recruiter description, no question reported yet: 60 minutes, a multi-part open-ended problem, and a working MVP you can run locally. It is graded on clarifying requirements, breaking the problem down, working with the AI, reviewing its code, testing, and handling changed requirements. One recruiter said every onsite is moving to this format.

Shopify AI coding interview

Called vibe coding

Two reports: a command-line robot that moves and turns, with batch commands, obstacles and a question about the right input and output design; and a text editor with append and remove, with follow-ups on abstractions and output formats such as binary, Morse and HTML.

Coinbase AI coding interview

Online assessment · built-in assistant

A 60-minute OA in a game simulation where you implement one method that decides whether a sprite should bounce. One candidate found the assistant unreliable. Another recognised it as a variant of a known flappy-bird task and wrote the roughly twenty lines by hand.

Google, Apple and others AI coding interview

Announced, few details yet

A September report says Google's L4 loop added an AI coding round and a solution design round, while other candidates still report the traditional format. An Apple candidate was told in April that every candidate would now get an AI-assisted round on CoderPad. A SoFi candidate interviewed through Karat in a browser editor whose assistant could not edit the code. ByteDance reports AI-enabled system design rounds: a file upload service, a monitoring dashboard and an agent quota system.

AI-enabled system design

Meta and ByteDance also run system design rounds with an AI chat open. Meta candidates describe classic prompts, such as a game leaderboard that shows the scores closest to yours or a ride-share system, as well as an open-ended design of an AI system where RAG or agents were fair game. One candidate found the AI of little use beyond looking something up or drawing a diagram. Prepare these like ordinary system design.

How to prepare

  • •Before prompting, say your approach out loud: the data structures, the classes and the algorithm. In stricter rounds, such as LinkedIn's, that part has to come from you.
  • •Write the skeleton yourself, then hand the AI one function at a time with your intent in the prompt. Read every change before you accept it.
  • •Open with a short ground-rules prompt: this is a timed interview on a weak machine; keep each step to a few minutes; test on tiny samples first; put a timeout on every run; and never run the full data set without asking.
  • •Explain each part quickly and ask for the next one. The parts you have not seen yet are usually where the points are.
  • •If the assistant is stuck on a bad approach, start a fresh conversation and tell it the data size, instead of arguing with a long context.
  • •Practise on the platform you will get. CoderPad, CodeSignal and HackerRank assistants are slower and weaker than the tools you use at work.
  • •Prepare an answer to how you use AI at work and how you check its output. Snowflake, Stripe and Amazon behavioral rounds ask it.

Practise on the questions these rounds actually use

Several companies run their AI round on the same multi-part questions as their regular rounds: Rippling’s expense rules engine and driver payments, Stripe’s rule parser, Zip’s codebase rounds. Each company guide lists the reported questions, how they grow part by part, and the follow-ups candidates got.

FAQ

What is an AI-assisted coding interview?▾
A coding round where you may, and are expected to, use an AI assistant. Most give you an existing codebase with tests and a problem that grows over several parts, and grade how you plan, direct the AI, verify its output and explain the result. Some companies use a built-in assistant (Meta, LinkedIn and Snowflake on CoderPad; Persona and Instacart on CodeSignal; Stripe on HackerRank). Others let you bring your own IDE and tools (Rippling, Harvey, Microsoft, Cresta, Ramp).
How is the AI coding round graded?▾
The most consistent signal across reports is that you should form the approach yourself and then direct the AI, rather than handing it the problem. A self-described LinkedIn interviewer said they look for prompts that show you digested the problem and chose the data structure and algorithm. A Snowflake interviewer told a candidate they grade how you ask the AI, write prompts and judge tradeoffs. Explaining the AI's code after each part comes up at Meta, Rippling, Zip and Datadog.
What questions does Meta ask in the AI-enabled coding round?▾
Reported Meta questions include a multi-part maze solver (bug fixes, direction tiles, keys and doors, a wall-clearing bomb), the largest set of words with no repeated letters, friend recommendation over about 100,000 users, a three-cards-to-15 card game you have to benchmark over many games, and a pathfinding problem that ends with a very large input. The round is one problem in parts, on CoderPad with a choice of models, and the last part is often a scale test.
Is the AI coding round harder than a normal coding round?▾
The algorithms are usually not harder, but several candidates call it the hardest round of their loop. The grading is less clear than a normal coding round, you don't know how many parts are coming, the built-in assistants are slow, and interviewers vary a lot in what they expect. More than one candidate who got everything working was still rejected.
Can I use my own AI tools?▾
It depends on the company. Rippling, Harvey, Microsoft, Cresta and Ramp let you use your own IDE and assistant (Ramp gives a $50 stipend for it). Meta, LinkedIn, Snowflake, Persona, Instacart, Stripe and Coinbase use the platform's built-in assistant. Ask your recruiter which tools are allowed and whether the AI may write the algorithm or only the implementation.
What is Capital One's agentic coding round?▾
One of three rounds in the TDP Power Day, next to behavioral and a case study. You get a full-stack app (React and Vite, Python and FastAPI), find and fix its bugs with Claude's help, and then add a feature. You still need to explain the code and your changes.
