Drop candidates into a real coding environment with AI tools. See who actually ships.
Challenges run on the stacks your team already ships with
The shift
Meta, Shopify, Canva, Cisco, companies are dropping algorithm interviews. The question isn't if algorithms are over, it's what comes next.
How it works
A full workspace in the browser. Virtual colleagues in Slack, a code editor, complex codebases, packages and AI tools.
Challenges test how candidates reason about code and architectural choices. "Claude pls fix. Don't make mistakes" won't work.
Session replay and summaries show you thought process and decision making skills. You see what they built, how they got there, and whether it works.
What you see
No lockdown browser. No webcam. No keystroke monitoring. Your candidates are professionals — treat them like it.
Challenge library
Each challenge drops you into a full virtual environment — databases, servers, APIs — the same stack you'd debug at work.
From the blog
If an AI can write any arbitrarily complex algorithm, what is it that the engineer actually does? We think the work breaks down into three distinct skills.
