Resumes and LeetCode can't measure what matters most in 2026 — how effectively engineers collaborate with AI. ArcEval gives candidates a real AI coding assistant and scores exactly how they use it.
85% of developers now use AI coding assistants daily. Yet every major hiring platform still tests candidates in isolation — banning the very tools they'll use on the job.
Three steps from challenge to comprehensive AI-collaboration report.
Design timed coding challenges in minutes. Choose from templates or create custom assessments tailored to your role.
Send a single assessment link to all candidates. They enter their details and begin immediately — no account setup required.
Every interaction is captured and analyzed. Receive detailed scoring across 8 dimensions with side-by-side candidate comparisons.
Candidates work in a sandboxed terminal with a real AI coding assistant. No multiple choice. No contrived puzzles. Real engineering.
Every prompt, response, and command is recorded and analyzed by our AI scoring engine.
Go beyond pass/fail. Understand exactly how each candidate thinks, communicates, and collaborates with AI.
Can the candidate break complex problems into AI-solvable chunks?
Do they ground their prompts in fundamental understanding?
Do they find novel approaches to prompt construction?
Can they refine AI outputs through intelligent follow-ups?
How effectively do they identify and resolve AI-generated issues?
Do they structure code well for AI-assisted development?
How precise and effective is their human-AI dialogue?
Do they minimize tokens while maximizing output quality?
Whether you're hiring full-stack developers, backend specialists, frontend experts, data engineers, or DevOps teams — ArcEval has purpose-built challenges for each discipline.
End-to-end engineers who work across the entire stack.
Server-side engineers building APIs, services, and infrastructure.
UI/UX engineers building responsive, accessible interfaces.
Engineers building data pipelines, ML systems, and analytics.
Infrastructure engineers managing deployments, CI/CD, and reliability.
Every challenge is designed to require iterative problem-solving with AI — they cannot be solved with a single prompt. Candidates must debug, reason, and adapt.
An e-commerce checkout has 5 interrelated bugs across frontend validation, API error handling, database transactions, and Stripe integration. Fixing one bug reveals the next — requiring systematic debugging across React, Node.js, and PostgreSQL.
A working collaborative document editor has no live presence. Add WebSocket-based cursor tracking, user avatars, and operational-transform conflict resolution to an existing Slate.js + Express codebase without breaking the save pipeline.
A full-stack dashboard loads in 14 seconds. The candidate must identify and fix N+1 queries in the API, excessive React re-renders, a missing database index, an uncompressed 3MB bundle, and a memory-leaking useEffect — each fix depends on profiling the previous one.
An existing SaaS app is leaking data between tenants. The candidate must audit the codebase, implement row-level security in PostgreSQL, scope API middleware, fix the frontend context provider, and verify isolation with existing test suites — all without breaking current functionality.
Convert 6 REST endpoints to a GraphQL API while keeping the existing REST routes working for backward compatibility. Requires understanding the data model, designing the schema, implementing resolvers with DataLoader for batching, and updating the React frontend to use Apollo Client.
All templates are fully customizable. Create your own challenges or modify any template to match your tech stack.
