Will LeetCode rounds be gone by October 2027?

Short answer: no. LeetCode-style rounds won't disappear in the next twelve months. They are losing their monopoly, though.

What's changing is that a pure algorithm round now gets paired with, or replaced by, a round where you work inside an existing codebase with an AI assistant. Meta, Canva and Shopify run these rounds today. Amazon allows an AI assistant in some online assessments, and Google is piloting one. Early-stage startups moved first and furthest. Big Tech still keeps at least one classic round for most levels, and mass hiring in India still runs on online DSA and aptitude tests.

Below is what the evidence shows, then my rough odds for the next year. Every probability in this post is my own estimate from the sources at the bottom, not a number from a survey.

What already changed, by date

The shift happened at named companies, and you can date it. In 2025 the moves were mostly about stopping cheating. In 2026 companies started allowing AI in the round itself.

That billboard matters more than its marketing tone suggests. The vendors selling assessments to thousands of employers are now selling the AI-assisted format. Mid-size companies rarely write their own tests, so when the vendor default changes, their interviews change with it.

Why it's happening

Two pressures push the same way. AI tools solve standard algorithm questions, so a remote LeetCode round no longer proves the candidate can solve them. And the job itself now involves directing and checking AI output, so the old round tests a skill that matters less than it used to.

You can measure the cheating side. In a 2025 interviewing.io survey of 63 interviewers, reported by The Pragmatic Engineer, 81 percent of Big Tech interviewers suspected candidates of using AI to cheat. 31 percent had caught one in the act, and 58 percent had changed their questions. Gartner's survey of 3,000 candidates found 6 percent admitted to interview fraud, and Gartner predicts that by 2028 one in four candidate profiles worldwide could be fake. Karat's survey of 400 engineering leaders found 71 percent say AI makes technical skills harder to assess.

The same Karat survey shows nobody has settled on an answer. In the US, 38 percent of leaders said they allow AI in interviews, while 62 percent of organizations overall prohibit it. Chinese companies allow it far more often.

Bar chart comparing US and China interview practices. Live technical interviews: 79% US, 87% China. Allow AI use: 38% US, 68% China. Automated code tests: 63% US, 49% China. Take-home projects: 45% US, 20% China.

Live technical interviews are still the norm, and only about a third of US leaders allow AI in them. Source: Karat, Engineering Interviews in 2026, survey of 400 engineering leaders in the US, India and China, Jan 2026.

What the people at the top are saying

Elon Musk never ran his companies' hiring on puzzle scores, and his 2026 statements lean even harder toward judging what a person has built. On May 21, 2026 he asked for engineers and physicists for SpaceXAI "even if you have zero prior experience in AI," and told them to email "~3 bullet points demonstrating evidence of exceptional ability." He added that making "a very complex thing do useful work" is a major plus. On the Collison and Patel podcast, as reported by Fortune, he put it bluntly.

"Don't look at the résumé. Just believe your interaction."

Sundar Pichai points the other way on format. He isn't dropping fundamentals. He wants to check them in person.

"Given we all work hybrid, I think it's worth thinking about some fraction of the interviews being in person."

"We're embracing it."

Put side by side, they fall into two camps. Musk, Shopify and Canva judge output and AI fluency. Google and Anthropic keep fundamentals and lock down the room. Both camps are walking away from the remote, unproctored LeetCode round. Neither is walking toward no technical bar at all.

Big Tech is adding rounds, not deleting the old one

The strongest evidence against a fast switch comes from inside Big Tech. In the interviewing.io survey, none of the 53 Big Tech and New Big Tech interviewers said their company had moved away from algorithmic questions. About half expected algorithm rounds to become less prominent in two to five years. About 20 percent expected them never to go away. Even Meta, the most aggressive mover, still gives most candidates one classic round.

The classic round survives at scale for boring, practical reasons. Big Tech screens hundreds of thousands of applicants, and a standardized algorithm test is cheap to grade and easy to defend as consistent. New-grad hiring has also shrunk. SignalFire's 2025 State of Talent report found new grads were 7 percent of Big Tech hires, with new-grad hiring down 25 percent from 2023 to 2024 and more than 50 percent from 2019. When there are a lot of applicants for a few junior seats, companies keep whatever filter cuts the pile fastest. Proctored or in-person rounds fix the cheating problem without changing the question type.

My odds for October 2026 to October 2027

These are my estimates. They rest on the dated changes above, the survey data, and how fast Meta and Google have moved so far. "Big five" means Google, Meta, Amazon, Microsoft and Apple.

Bar chart of estimated probabilities by October 2027. Online assessments stay the first filter for big-tech new grads: 90%. Three or more of the big five run an AI-assisted round: 70%. Another big-five firm adds in-person finals: 60%. Google expands its AI-assisted pilot: 55%. One big-five firm drops DSA for all SWE levels: 15%. Indian IT services drop DSA and aptitude online assessments: 5%. Pure DSA rounds gone at all of the big five: 3%.

An AI-assisted round becoming standard within a year is likely. LeetCode-style rounds disappearing is not. Source: my estimates, Oct 2026, based on the sources below.

Here's what that means for you as a candidate. The middle column is the chance that a typical company in that tier, interviewing you in the next twelve months, has at least one LeetCode-style round somewhere in the process, online assessment included.

Company tierChance of a LeetCode-style roundWhat sits next to it or replaces it
Big Tech (Google, Meta, Amazon, Microsoft, Apple)~90%AI-assisted codebase round, in-person or proctored finals, system design for mid level and up
Large product companies and late-stage unicorns~65%Vendor AI-assisted assessments (HackerRank, CoderPad, Karat), practical coding, take-homes
Indian product companies hiring at scale~85%Online DSA test as the filter, then machine coding and system design
Indian IT services and campus mass hiring~95%Aptitude plus DSA online tests, little change expected
Series A to C startups~40%Build-with-AI rounds on screen share, take-homes, debugging real code
Seed and pre-seed startups~20%Portfolio and shipped work, paid trial days or weeks, founder conversation

The startup rows are the weakest numbers here. I couldn't find any survey that measures startup interview formats by stage. Those rows rest on The Pragmatic Engineer's reports that many startups dropped algorithm questions, on examples like Linear's paid work trials, and on how founders like Musk describe hiring. Read them as a direction, not a measurement.

What would change my mind

What I'd actually do right now

Don't stop preparing for algorithm rounds. Also don't keep grinding them as your only plan.

The online assessment is still the gate at Big Tech and most Indian companies, so you need medium-level fluency in the common patterns: arrays and hashing, two pointers, sliding window, trees, graphs with BFS and DFS, heaps, and basic dynamic programming. Past a few hundred problems the extra return gets small, because the new rounds test something else.

That something else is working in code you didn't write, with an AI assistant, and checking what it gives you. Meta's round hands you a multi-file codebase, asks you to build a feature, extend partial code, or fix a bug, and scores how well you verify and debug. Canva says candidates with little AI experience struggled even when they could code. You can practice this directly. Clone an unfamiliar open-source repo, add a small feature with tests using Claude or Cursor, and make sure you can explain every line you kept and every suggestion you threw out.

For startups, shipped work decides it. Musk's three-bullet email is the extreme version of what most early-stage founders want. Two or three projects that real people use, each with a public repo and a short write-up of the hard decisions, will beat a LeetCode count at a seed-stage company.

How you split your time depends on where you're applying. Aiming at Big Tech or Indian product companies? Roughly half on algorithm patterns, a quarter on AI-assisted codebase practice, and a quarter on system design or projects. Aiming at startups? Flip it. About a fifth on algorithms and the rest on building and AI-assisted work. That split is my judgment call from the round formats above, not a measured result.

I'm building a code editor with agents. Here's how the first three days went.

Helm is a Rust code editor that agents write and I review. Three days in, there's no window yet, but there's a text core, 297 passing tests and a CI setup built to stop agents from cheating.
