Prelim / 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.

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

Questions teams ask us.

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

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

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