Per-block scores, code evolution snapshots, behavior timeline, and integrity signals. AI grades every question type β€” make a confident call in minutes, not days.

Challenge Types

Six ways to see what candidates can do

Mix any of these into one assessment β€” AI generates and grades them all from your job description. Voice and video evaluation are English-only for now.

AI-Assisted Dev Β· ScenarioAI graded

Your AI assistant wrote this auth fix and all tests pass. A teammate says "just ship it." What do you do?

Ship it β€” every test is green
βœ“Review for the edge cases the tests don't cover, then ship
Trust the AI β€” it was trained on millions of repos
AI verdictStrong

Caught the security gap the AI and the teammate both missed. Treats AI output as a draft, not gospel.

New Β· the 2026 skill

AI-Assisted Development

The skill that actually defines the job now: judgment with AI. Real scenarios test when to trust AI output, when to push back, and how to review AI-generated code β€” the competency no other platform measures.

Coding Challenges

Real problems in 14 languages β€” JavaScript, Python, Java, Go, React, SQL and more. Candidates write code in a VS Code-like editor against hidden test cases, re-run and scored on our servers so a result can't be faked.

Code Review

Candidates review intentionally buggy code β€” identify issues, suggest fixes, explain their reasoning. AI scores their analysis against ground truth, testing the judgment that separates senior engineers from the rest.

Voice Q&A

Ask about system design, architecture trade-offs, or debugging. Candidates record a spoken answer; AI transcribes and evaluates the content β€” no scheduling, no back-and-forth. Spoken evaluation is English-only for now.

Team Collaboration Β· ScenarioAI graded

It's 6pm before a release. A teammate's PR has a bug blocking the deploy and they look stuck. What do you do?

Force-merge and fix it after release

Unblocks the team over protecting ego or the clock. The instinct that scales past one engineer.

Beyond code

Team Collaboration

Realistic workplace moments β€” a blocked release, a teammate's messy PR, a tight deadline. Single-select judgment calls, AI-scored, that surface how someone actually behaves on a team.

Video Intro

A timed, guided recording β€” candidates introduce themselves or respond to a custom prompt. Auto-transcribed and shared with everyone reviewing the hire. Transcription and evaluation are English-only for now.

Up to 5-min recordingAuto-transcribedTeam review & sharing

Integrity & Proctoring

Results you can actually trust

Every assessment is proctored end to end. Candidates turn on their camera and share their screen before they start β€” and every score is re-checked on our servers, so a tampered browser can't fake a pass.

Camera + screen share

Candidates enable their webcam and share their full screen for the whole assessment. Both are captured and available to reviewers.

AI watches the session

Tab switches, clipboard pastes, focus loss and missing-face moments are tracked and rolled into an integrity score β€” the AI flags suspicious behaviour automatically.

Server-validated scoring

Every code submission is re-run on our servers against the real test suite. Candidates can't tamper with their score client-side β€” the number you see is the number we computed.

Full behaviour replay

Code-evolution snapshots and a behaviour timeline show exactly how a solution was built β€” not just the final answer.

Platform

Built for engineering teams

Everything you need to run technical hiring end to end β€” and nothing you don't.

01

One job description in

Paste a JD β€” or pick a template β€” and AI builds the entire assessment: challenges, scenarios, and voice questions tuned to the exact role. No question bank to curate, no manual setup.

02

AI grades everything

Spoken answers, code-review comments, written responses, judgment scenarios, and test results β€” all scored automatically. No manual rubrics, no subjective guesswork.

03

A hiring control room

A live pipeline (invited β†’ started β†’ completed β†’ reviewed), a 'needs attention' queue, stalled-candidate detection, and one-click reissue of expired links. You manage the whole funnel, not just the test.

04

AI hire recommendation

Beyond a score: a clear Strong Hire / Hire / No-hire call with the reasoning behind it β€” so you walk into the decision already informed.

05

Your brand, not ours

Upload your logo and the assessment plus every candidate email carries your company's name. Candidates feel like they're interviewing with you, not a third-party tool.

06

Candidates don't hate it

Magic-link access with no install, a guided warmup, a real editor with auto-save and offline recovery, and a calm finish. When the experience feels professional, candidates perform at their real level.

Why QuizMaster

More than a coding test

HackerRank, Codility, and TestGorilla only test one thing. QuizMaster tests how candidates code, review, communicate, and work with AI β€” and grades it all automatically.

Teams who hire differently

What teams are saying

β€œWe used to spend 3 hours picking questions and still weren't confident they were the right ones. Now we paste a JD and have a better assessment in a few minutes. The code review blocks alone filter out candidates who would have looked fine on paper.”
Sarah Chen
VP of Engineering
TechFlow
β€œThe voice Q&A blocks replaced our first-round phone screens entirely. We send the assessment, get back structured responses, and only talk to people who already demonstrate system design thinking. It cut our time-to-hire by three weeks.”
Marcus Rodriguez
Engineering Manager
DataSync
β€œI can see exactly how a candidate built their solution β€” not just the final answer. The code evolution snapshots caught people who submitted solutions they clearly didn't understand. That's saved us from several bad hires.”

Common questions

Still have questions? Talk to us

Four types: coding challenges (14 languages), code review (candidates find and explain bugs in real code), voice Q&A (spoken responses to written prompts, AI-transcribed and graded), and video intros (timed candidate recordings, auto-transcribed). You can mix all four in a single assessment.
For voice Q&A: candidates record a spoken response, our AI transcribes it and evaluates content quality against the expected criteria. For code review: candidates comment on a buggy code block; AI matches their findings against a ground truth list of issues and scores coverage, accuracy, and insight depth.
14 languages and frameworks: JavaScript, TypeScript, Python, Java, C++, C#, Go, Kotlin, Swift, Ruby, Rust, R, React, Vue, and SQL. All updated to the latest runtime versions β€” Node.js 21, Python 3.11, Java 21, Go 1.21, and more.
Multiple layers: copy-paste event detection, tab-switch tracking, keystroke metrics, network request monitoring, and optional camera proctoring. Every submission includes a full integrity score and a behavior timeline β€” not just a flag, but a complete record of what happened during the assessment.
Yes. AI generates a complete assessment as a starting point β€” you can edit, reorder, add, or remove any block. Adjust difficulty levels, set custom time limits per challenge, or write your own question from scratch.
Candidates receive a magic link, complete a guided warmup flow so they know what to expect, then work through the assessment at their own pace. Code is auto-saved with offline support. The experience is designed to feel like a real engineering environment β€” not a gotcha test.
