Coding Assessment Platform
Hire developers on proven code, not interview anecdotes. AssessZen runs candidates' code live against hidden test cases, flags AI-written solutions, and replays every keystroke so you can see exactly how they think.
Everything you need to succeed
Twelve capabilities built to run your assessments end to end.
Live Code Execution
Every submission runs in a real, sandboxed compiler environment with live stdout. Candidates see output instantly and iterate like they would on the job.
Hidden Test Case Scoring
Each question is evaluated against hidden test cases — not just example ones. Edge cases are evaluated, so passing means actually solving the problem.
Keystroke + Session Replay
Review the exact solving path — every edit, compile, and test run. See whether candidates arrive at the answer through reasoning or trial and error.
AI & Plagiarism Detection
Submissions are screened against AI-generated and historical code. Suspicious fragments are flagged side-by-side in the scorecard for manual review.
Browser IDE Built In
Syntax highlighting, autocompletion, and a live console in the browser itself. No downloads or local setup — just open the link and start solving.
Anti-Cheat Engine
Tab-switch detection, multi-presence monitoring, and copy-paste prevention keep the session honest from invite to submit.
Features
A quick look at the features that AssessZen provides.
Run Code Live, evaluated by hidden testcases
Candidates solve problems in a professional-grade editor and their code runs against real test cases — including hidden ones they never see. Passing test cases means passing the bar, not vibes, and scoring is computed automatically the moment they submit.
A language for every role
Ship assessments in JavaScript, Python, Java, C++, C#, Go and many other — with time limits you configure per question. Environments are sandboxed, so even untrusted code runs safely.
Catch AI and copied code
AI-assisted solving is the new normal, which is why AssessZen compares submissions against historical and public code, flags AI-written snippets, and monitors tab-switching, copy-paste and multi-presence. Code replay ties it together, showing you the exact solving path after every submission. Identifies the unwanted keywords in the code and analyse the user's behaviour during coding
