GrepS objectively evaluates real-world developer competencies — not algorithmic puzzles. Science-based assessments benchmarked against thousands of professional developers worldwide.
Each assessment spans six core competency dimensions, giving you a complete picture of a developer's capabilities — not just one slice.
Measures throughput and efficiency. How quickly does a developer deliver working code under realistic conditions?
Evaluates test quality and coverage. Are tests meaningful, well-structured, and do they actually catch bugs?
Assesses the ability to modify existing code without introducing regressions into previously working behavior.
Tests the ability to translate requirements into working, maintainable code from scratch in real conditions.
Measures the ability to improve code structure and quality without changing its external behavior.
Evaluates design decisions — appropriate use of abstraction, encapsulation, and object-oriented principles.
The entire assessment lifecycle is automated. You define what to test — GrepS handles everything else.
Choose assignment types, set grading parameters, and define the test structure for your team or role.
Send personalised invites. Candidates access a clean portal and work on real code in their own environment.
Submissions are compiled, tested, and scored instantly against objective criteria — no manual review required for most graders.
Get per-dimension scores, grader breakdowns, and evidence trails to make confident, data-driven hiring decisions.
// Candidate submission — ShoppingCart.java public class ShoppingCart { private final List<Item> items = new ArrayList<>(); public void addItem(Item item) { items.add(item); } public BigDecimal total() { return items.stream() .map(Item::price) .reduce(BigDecimal.ZERO, BigDecimal::add); } }
Purpose-built for technical hiring teams who need reliable, repeatable results — not a general-purpose quiz tool.
Composable graders — JUnit results, time metrics, manual review, and computed expressions — topologically resolved and combined into a single weighted score.
Each submission runs in a disposable container with no internet access, ensuring consistent, reproducible scoring conditions every time.
Separate user pools for administrators, graders, and candidates. Full audit trail of every action, invite, and decision.
Version-controlled assignments with variant branching. Swap or update assignments between assessment runs without affecting existing results.
Every score is backed by captured evidence — test output, container logs, timing data — so you can always explain a result.
Stop guessing. Start measuring. GrepS gives you objective, evidence-backed data so every hiring decision is one you can stand behind.
