My Mock Interview – AI Tailored Interview Platform: Architecture & Performance Benchmark
Key Takeaways
- 7-agent LLM pipeline performs end-to-end interview preparation from JD parsing to final scoring
- Automated gap analysis cross-examines candidate experience against job requirements
- SEO-first hybrid architecture combines static landing with React 19 SPA
- Real-time rubric scoring (0-10) evaluates both technical accuracy and communication clarity
The Challenge: Why My Mock Interview Was Built
Traditional interview preparation suffers from three critical limitations:
- Generic content – Standard question banks don’t account for specific job requirements
- Subjective feedback – Human coaches provide inconsistent evaluations
- Hidden gaps – Candidates often miss critical competency mismatches
My Mock Interview addresses these challenges through a multi-agent AI architecture that:
- Analyzes job descriptions and resumes with structured schema validation
- Performs automated gap analysis to identify competency deficits
- Generates tailored question sequences targeting specific weaknesses
- Provides objective, rubric-based scoring (0-10) for each response

Performance-Optimized Tech Stack
- Backend: FastAPI (Python 3.12) with asyncpg for PostgreSQL 16 connectivity
- Frontend: React 19 SPA with Vite bundler
- Storage: MinIO S3-compatible object storage for resume files
- LLM Orchestration: OpenRouter multi-model inference endpoint
Key Features & Benefits
Automated Gap Analysis
The system performs matrix analysis comparing:
- Required skills vs. demonstrated experience
- Preferred qualifications vs. candidate background
- Job responsibilities vs. past project scope
Dynamic Question Sequencing
Questions are dynamically weighted across four categories:
| Category | Weight | Example |
|---|---|---|
| Technical Depth | 40% | “Explain how you’d implement a distributed cache” |
| Behavioral | 30% | “Describe a conflict with a colleague” |
| System Design | 20% | “Design an API rate limiter” |
| Gap Probes | 10% | “Your resume shows no cloud experience – how would you compensate?” |
Real-World Applications
