Challenge Types

Four ways to see
what candidates can do

Mix and match challenge types in a single assessment. AI generates and grades all of them from your job description.

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. You get pass rates, time spent per challenge, and code evolution snapshots.

Code Review

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

Voice Q&A

Ask about system design, architecture trade-offs, or debugging approaches. Candidates record a spoken response up to 120 seconds. AI transcribes and evaluates content quality β€” no scheduling, no back-and-forth.

Platform

Built for engineering teams

Everything you need to hire better developers β€” and nothing you don't.

01

Four Challenge Types

Coding, code review, voice Q&A, and video intros β€” the most comprehensive technical assessment platform on the market. Mix all four in a single assessment.

02

Job-Specific by Design

Every challenge is generated from your JD. React engineers get React challenges. Backend roles get backend problems. Zero generic algorithm puzzles.

03

AI Grades Everything

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

04

14 Languages & Frameworks

JavaScript, TypeScript, Python, Java, Go, Rust, Kotlin, C++, React, Vue, SQL, and more β€” always updated to the latest runtime versions your team actually uses.

05

Deep Behavior Analytics

Code evolution snapshots show exactly how candidates built their solution. Behavior timeline tracks focus, copy-paste, and tab switches. Full integrity scoring included.

06

Candidate Experience

A guided warmup flow, VS Code-like editor, and auto-save with offline recovery. When the assessment feels serious, candidates perform at their actual level.

Why QuizMaster

More than a coding test

HackerRank, Codility, and TestGorilla only test one thing. QuizMaster tests four β€” and grades them 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 30 seconds. 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.
