Manual Screening Bottlenecks

High-volume recruitment faced critical challenges with manual resume review processes. Inconsistent evaluation criteria, time-consuming manual checks, and inability to verify candidate information at scale were limiting hiring efficiency.

The Numbers That Hurt:

  • Average 15-20 minutes per resume for thorough review
  • 40% variance in screening decisions between reviewers
  • No real-time validation of candidate claims

Autonomous Screening Architecture

We developed an autonomous agent that handles the entire screening workflow - from resume parsing to LinkedIn validation to final recommendations.

System Components

Document Processing

Technology: Custom Parser + OCR

Handles multiple resume formats (PDF, DOCX, TXT) with high accuracy extraction of structured data.

Profile Enrichment

Technology: LinkedIn APIs

Automatically fetches and validates candidate information from LinkedIn profiles for verification.

Evaluation Engine

Technology: Claude 3 Sonnet

Analyzes candidate fit based on job requirements, experience relevance, and skill matching.

Scoring System

Technology: Custom ML Layer

Proprietary scoring algorithm that weighs multiple factors for consistent evaluation.

Processing Workflow

  1. 1.
    Resume Ingestion: Automated parsing of incoming applications from multiple sources
  2. 2.
    Data Extraction: Structured extraction of education, experience, skills, and achievements
  3. 3.
    LinkedIn Enrichment: API calls to fetch current role, recommendations, and skill endorsements
  4. 4.
    Comprehensive Analysis: Claude evaluates technical fit, experience relevance, and red flags
  5. 5.
    Scoring & Ranking: Multi-factor scoring produces ranked candidate shortlist
  6. 6.
    Report Generation: Detailed assessment with strengths, concerns, and interview suggestions

The system has transformed high-volume hiring from a bottleneck to a competitive advantage. Recruiters receive pre-screened, ranked candidates with detailed assessments, allowing them to focus on high-touch candidate engagement.

Engineering Challenges & Solutions

Resume Format Chaos

Built a robust parsing pipeline that handles 50+ resume formats with 98% extraction accuracy using a combination of rule-based and ML approaches.

LinkedIn API Rate Limits

Implemented intelligent caching and batch processing to optimize API usage while maintaining real-time performance.

LLM Consistency

Developed a prompt engineering framework that ensures Claude provides consistent evaluations using structured output formats.

Bias Mitigation

Careful prompt design and regular audits ensure the system focuses on skills and experience, not demographic factors.

Real-World Implementation

Case Study: Tech Company Hiring Sprint

A technology company needed to hire 50 engineers in 60 days. Here's how our system performed:

  • Received 3,000+ applications in the first week
  • System processed all resumes within 6 hours
  • Delivered ranked shortlist of 300 candidates with detailed assessments
  • 80% of system-recommended candidates progressed to technical interviews
  • Filled all positions 2 weeks ahead of schedule
