A Full Coding Assessment Suite
Screen engineers on real code, not multiple-choice. Candidates solve problems in a browser IDE across 13+ languages, executed and graded on a sandboxed backend — with adaptive difficulty and a four-layer integrity system that catches AI-generated answers, plagiarism, and proxy attempts.

What Makes It Powerful
13+ Production Languages
Candidates code in Python, JavaScript, TypeScript, Java, C++, C, C#, Go, Ruby, PHP, Rust, Kotlin, and Swift — in a full browser IDE with real syntax highlighting. Additional language cohorts flip on as you need them.
Real Compile-and-Run Grading
Submissions execute on a sandboxed backend and are graded against real test cases — not pattern matching. Correctness, runtime, and edge-case handling are measured on actual program output.
Adaptive Difficulty
A CAT-style engine adjusts problem difficulty to each candidate's demonstrated skill, so a single assessment cleanly separates strong engineers from the rest without wasting anyone's time.
AI-Generated Code Detection
Every submission is analyzed for tell-tale signatures of ChatGPT and other LLMs — catching pasted AI answers that would otherwise sail through a traditional test.
Proctoring & Plagiarism Analysis
Live webcam proctoring with identity verification, tab-switch and paste monitoring, keystroke-pattern authorship checks, and cross-candidate plagiarism analysis — a four-layer integrity system.
Live & Async Rounds
Run take-home assessments candidates complete on their own time, or collaborative pair-programming interviews with a shared editor and live evaluation — the same engine powers both.
How It Works
Build the Assessment
Assemble challenges from the curated problem bank or auto-generate role-specific problems. Set the languages, difficulty band, and time limit to match the position.
Send a Login-Free Link
Candidates open a secure link and code directly in the browser IDE — no installs, no accounts. Consent and proctoring are set up before the timer starts.
Run Code & Verify Integrity
Code executes against hidden test cases on a sandboxed backend while integrity checks — AI detection, plagiarism, proctoring, keystroke analysis — run in parallel.
Scorecard & Compare
Get a scorecard with correctness, code-quality, and performance metrics plus a single integrity verdict — then compare candidates side by side to make the call fast.
