Technical Interviews
Built for the AI EraModern TeamsReal EngineersWhat Mattersthe AI Era

EvalX is an AI-era technical interview platform that evaluates how engineers think, reason, and collaborate with AI during real development workflows. Candidates work in a browser-based IDE with multi-model AI assistance (Claude, GPT-4o, Gemini) while the system captures every diff, prompt, and decision. AI evaluators then score across six dimensions: Problem Framing, AI Usage Quality, System Design, Code Quality, Adaptability, and Explanation & Ownership.

Our system non-invasively logs all AI prompts and responses during the session. It analyzes coding patterns, tool usage, and problem-solving approaches in real-time. We identify whether candidates are driving the AI or blindly copying — measuring collaboration quality, not just output.

Candidates work through 2-5 checkpoints in a real IDE. They write code, use AI tools, commit changes, and explain their decisions. Our system captures everything: git diffs, AI interactions, test results, and written explanations. After completion, AI evaluators score across multiple dimensions within minutes.

Yes. Professional and Enterprise plans include an AI-powered template builder. Describe your ideal challenge in natural language, and our system generates a complete template with project files, test suites, checkpoints, and evaluation criteria. You can also import existing codebases.

Traditional platforms test algorithm memorization in sandboxed editors. EvalX provides a full IDE environment with AI assistance — because that's how engineers actually work. We measure system design thinking, AI collaboration quality, adaptability, and code ownership — not whether someone memorized BFS.

EvalX evaluates candidates across six dimensions: (1) Problem Framing (15%) — did they think before coding? (2) AI Usage Quality (20%) — did they drive the AI or follow it? (3) System Design (20%) — did they choose architecture or just optimize? (4) Code Quality (15%) — does the code survive change? (5) Adaptability (15%) — do they panic or pivot cleanly? (6) Explanation & Ownership (15%) — can they defend their decisions under pressure?

AI Hiring Intelligence is a category of technical hiring solutions that use AI to capture comprehensive evidence during interviews — code submissions, AI usage patterns, behavioral signals — and deliver objective, data-driven evaluation. EvalX is the AI-native platform in this category, replacing gut-feeling hiring decisions with multi-dimensional, evidence-based assessment.

Data security is our top priority. EvalX uses AES-256 encryption at rest and in transit. We offer automated data purging policies and strict role-based access controls. Enterprise plans include SOC2 Type II compliance, SSO/SAML, and audit logging.

Any stack your team uses. Our templates support Python, Node.js, Go, Java, React, Next.js, and more. The IDE environment is fully customizable — candidates can install extensions and use their preferred tools. If you can code it, we can evaluate it.

EvalX is built for CTOs, VP Engineering, and engineering managers at product-driven tech companies with 30-300 engineers who are hiring continuously. It is especially valuable for teams that have adopted AI in their development workflows and need to evaluate candidates in that same context.

Karat uses human interviewers at $200-400 per interview, targeting enterprise-only customers. EvalX is fully automated, AI-powered, and accessible to mid-market teams. EvalX captures richer behavioral signals through its multi-model AI environment and delivers results in minutes, not days.

Yes! Our self-evaluation mode at practice.eval-x.com lets individual developers evaluate their own coding skills using the same AI-powered platform that companies use. You get multi-dimensional scoring with actionable feedback. Start with a free evaluation — no credit card required.

The Explorer tier gives you one 45-minute evaluation every 14 days with selected dimensions scored, plus your strongest and weakest dimension insight. You work in the same full IDE environment with AI assistance. Upgrade to Builder ($39 one-time) for 5 evaluations with all dimensions and detailed evidence, or go Pro ($79/mo) for up to 10 evaluations per month with personalized coaching, percentile benchmarks, and progress tracking.
