Assessments
Structured assessments for educators, employers, and self-evaluation - in development.
Timed challenges
A fixed set of problems with a countdown timer. Solve as many as you can before time runs out, then get a full score breakdown - accuracy, speed, hints used, and lines of code.
Timed challenges test performance under pressure and mirror the conditions of real analytical work, where speed and correctness both matter.
Subject matter tests
Graded assessments covering a single topic area: Descriptive Statistics, Regression, Data Processing, or Causal Inference. Each test produces a detailed score - by problem, by subtopic, and overall - so you know exactly where the gaps are.
Pass/fail thresholds are not built in. Educators and employers set their own from the results data, rather than relying on a hardcoded cutoff.
Shareable assessment links
Create a link and send it to candidates or students. Configure the topic mix, difficulty distribution, and time limit. Recipients complete the assessment on mxlabs; full results and stats flow back to the sender.
Designed for hiring managers who want to screen for analytical skill in practice, and educators who want to assess a cohort against a consistent problem set.
What you get
Every assessment format includes the same reporting and control layer.
Stats and reporting
Time per problem, attempt count, hints used, lines of code, and percentile ranking against the full user base. Customisable - senders choose which metrics to surface and in what form.
AI feedback control
Enable or disable AI review per assessment. For practice, you might want full AI feedback. For a hiring screen, you might want none. The sender decides what feedback is available to the taker.
AI validation
Senders can flag suspicious submissions. AI analysis reviews code patterns, solution style, and timing to surface submissions that may not reflect genuine independent work.
Anti-AI features
Per-session data generation means each taker gets a different dataset for the same problem - so no two submissions are identical and AI-generated solutions can't be copied directly.
