The shift

LeetCode was built for a different era. The industry knows it.

Meta, Shopify, Cisco — companies are dropping algorithm interviews. The question isn't whether this changes hiring. It's whether you move first.

From the blog

The skill nobody tests for →

Over the last year, the best engineers have completely changed how they work. They don't write code by hand anymore, they talk to agents, interrogate them, make architectural decisions, scope projects, and verify output.

How it works

Three steps. No whiteboards.

01

Real environment

A full VS Code workspace in the browser. Terminal, files, packages — everything your engineers use daily.

02

Solve with AI

Claude Code, Codex, Cursor, Copilot — the same tools your team uses. The challenge is using them well, not memorizing algorithms.

03

See how they think

Automated tests validate the solution. You see what they built, how they got there, and whether it works.

Challenge library

Real problems. Not algorithms.
