    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
    Live Project Access: https://interview.nevatal.id

    The Challenge: Why My Mock Interview Was Built

    Traditional interview preparation suffers from three critical limitations:

    1. Generic content – Standard question banks don’t account for specific job requirements
    2. Subjective feedback – Human coaches provide inconsistent evaluations
    3. 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

    Core Architecture & Technical Stack

    The 7-Agent Pipeline

    Job Description → JD Parser →
                            ↘
    Resume → Resume Analyzer → Gap Analysis → Spec Builder → Question Generator
                                               ↓
    Answer Evaluator ← Candidate Responses ← Generated Questions
                                               ↓
                                            Final Reviewer
    

    Each agent maintains strict isolation of responsibilities with Pydantic schema validation between stages.
