The Ultimate Interview Simulation

Stop memorizing standard answers. Start building real intuition with dynamic, unpredictable interview scenarios.

Real-Time Voice AI

Converse naturally with an AI interviewer. It interrupts, asks probing follow-up questions, and challenges your design choices just like a real engineer.

Live Whiteboarding

Draw your architecture on our collaborative canvas. The AI sees your components instantly and bases its questions on your actual diagram.

Objective Scoring

Receive a detailed breakdown of your performance across scalability, fault tolerance, security, and cost-efficiency after every session.

Unscripted Scenarios

Whether you're architecting a global ride-sharing backend or a high-frequency trading platform, our AI dynamically generates requirements and constraints on the fly.

  • Adapts to your experience level
  • Simulates extreme scale constraints
Scenario: E-Commerce Surge

"Design an inventory system that can handle 100,000 checkout requests per second during Black Friday without overselling items."

System generates dynamic edge cases based on your initial database choice.

Comprehensive Database & Review

Every mock interview is recorded and transcribed. Review your past Q&A, diagram snapshots, and AI feedback to identify your weakest architectural areas before the real thing.

Frequently Asked Questions

Everything you need to know about practicing with tech-interview.ai

What is tech-interview.ai?
tech-interview.ai is an AI-powered platform that simulates real cloud architecture interviews. You practice system design by drawing on an interactive canvas while an AI interviewer asks probing questions over voice — just like a real interview at companies like AWS, Google, or Microsoft.
How does the AI interviewer work?
Our AI interviewer, Alex Chen, is modeled after a Principal Solutions Architect with 18 years of experience. It uses GPT-4o for natural voice conversation and adapts its questions to your seniority level (Junior, Mid, Senior). It analyzes your architecture in real-time and asks follow-up questions about trade-offs, failure modes, and cost optimization.
Which cloud providers are supported?
Currently, we focus on Microsoft Azure with 18 unique interview scenarios covering fintech, healthcare, gaming, IoT, fraud detection, and more. Each scenario uses real Azure services like AKS, Cosmos DB, Event Hubs, and Azure AI Services.
Is there a free plan?
Yes! Our free plan includes 1 full interview session so you can experience the platform. Pro and Lifetime plans unlock unlimited interviews, detailed scoring across 6 dimensions, and real-time coaching feedback.
What kind of feedback do I get after an interview?
After each interview, you receive a detailed assessment with scores across 6 dimensions: Architecture Design, Security by Design, Scalability & Performance, Consultative Communication, Engineering Depth, and FinOps & Cost Optimization. Each score is visualized on a radar chart with specific strengths and areas for improvement.
How is this different from reading system design books?
Books teach you theory, but interviews test your ability to think on your feet, communicate trade-offs under pressure, and handle curveball questions. tech-interview.ai simulates that real-time pressure with an AI that pushes back on your decisions, asks "what if" scenarios, and evaluates your communication style — not just your technical knowledge.
