Developer sourcing for the vibe-coding era
Find developers
who think in systems,
not what they type.
The real problem isn't interviewing — it's finding signal in a pile of polished, AI-assisted submissions. Langos cuts through the noise by revealing how a developer reasons, not just what they ship.

The Problem
Finding great
developers just
got harder.
Every candidate now submits polished, AI-assisted work. The signal is gone — and the tools built to find it haven't caught up.
Three filters that no longer filter
Résumés are indistinguishable
ChatGPT writes a compelling senior engineer profile in seconds. Every applicant now looks like the candidate you're looking for.
Take-homes are trivially AI-completable
Any task you can set, a model can solve. You're no longer screening for skill — you're screening for who remembered to run the linter.
Thinking style is still completely invisible
The most predictive signal — how a developer reasons, overrides, and refines — is never captured by any résumé, test, or portfolio submission.
The Solution
Meet Langos — a sourcing layer
that reveals how developers think.
Live Demo
AI-native

01
The Environment
Candidate clicks a private GitHub Codespace link. Zero setup. Real tooling.
02
The Vibe Recording
Pre-loaded extension captures every prompt, AI response, override, and refinement.
03
The Time Machine
Reviewers replay the entire session — seeing the thinking, not just the result.
How it works
From applicant pile
to genuine signal in three steps.
01
Send a screening task
Replace your take-home with a Langos Challenge. Langos Claude Code based extension captures the thinking behind each decision on the cloned repo.

02
They work naturally with AI
The VSCode extension invisibly records the full developer-AI dialogue: prompts, suggestions, overrides, diffs.

03
You see who actually thinks
A full session playback surfaces architectural reasoning, prompt quality, and override patterns — so you shortlist on signal, not submission polish.

What teams say
The people doing the hiring
tell it best.
Early access feedback from engineering teams who replaced their take-home process with Langos.
"
We used to spend three rounds of interviews trying to figure out if someone could actually architect a system. Now we know after the screening task. The override patterns alone tell you more than a whiteboard ever did.
"
What surprised me was seeing candidates who wrote beautiful code but accepted every single AI suggestion without question. That's not who you want designing your infrastructure. Langos makes that invisible bias visible.
"
We shortlisted a candidate who scored mid-tier on the usual criteria. Her override patterns showed she consistently pushed back on AI's naive solutions. She's now our best hire in two years. We would have filtered her out.
"
The signal-to-noise ratio in our pipeline went from painful to actually manageable. We interview fewer candidates now and make better offers. The time saved on wasted final rounds alone justifies the switch.
