Products / Technical Assessment

Technical assessment that reflects the job.

Measure how candidates actually build — reading code, designing systems, and shipping working solutions — instead of memorized algorithm trivia.

How it works

Realistic tasks, reasoning-aware scoring.

Candidates work against realistic problems while specialized assessors grade correctness, structure, and approach. The result is a skills matrix that maps to the competencies your team actually needs.

  • Real repositories and realistic problems
  • System design and DevOps, not just algorithms
  • Reasoning-aware grading, not keyword matching
  • A ranked, explainable skills matrix

FAQ

Questions teams ask us.

Do you support our stack?+

Prelim ships environments for the major languages and frameworks and supports custom repos close to your real codebase.

How is it graded?+

Specialized assessors score reasoning and correctness, producing an explainable skills matrix rather than a single opaque number.

Can candidates use AI copilots?+

You choose per assessment — allow, restrict, or observe — and Prelim scores the quality of judgment either way.
