Step-by-Step Workflow

Phase 1: Inbound Application Processing

Trigger: New application via email (IMAP node) or webhook from Lever/Greenhouse/Workable.

Step 1.1 — Resume Ingestion:

• Accept attachments (PDF, DOCX, TXT)
• Convert to plain text using n8n’s PDF Extract node or the Python pdfminer library
• Store raw text in Airtable field resume_raw_text

// Code node — extract text from PDF attachment
const fs = require('fs');
const pdfPath = $binary.data.filePath;
const pdfBuffer = fs.readFileSync(pdfPath);

// Use pdf-parse or external API for conversion
// Fallback: use Google Doc AI for scanned resumes
const text = await extractPdfText(pdfBuffer);
$json.resume_text = text;
$json.file_type = $input.first().json.mimeType;

Step 1.2 — Multi-language Detection:

• Pass text through DeepL language detection or a lightweight OpenAI Whisper classification
• If non-English detected, auto-translate to English using DeepL API
• Store original-language text for reference; use the English version for standardized scoring

Phase 2: AI-Powered Resume Parsing and Scoring

Step 2.1 — Structured Data Extraction (GPT-4o):

System prompt: You are an HR tech extractor. Parse this resume and return JSON:
{
  "full_name": "...",
  "email": "...",
  "phone": "...",
  "location": { "city": "...", "country": "..." },
  "work_experience": [
    {
      "company": "...",
      "title": "...",
      "start_date": "YYYY-MM",
      "end_date": "YYYY-MM" or "present",
      "responsibilities": ["..."],
      "tech_stack": ["..."],
      "seniority_level": "junior" | "mid" | "senior" | "lead"
    }
  ],
  "education": [
    {
      "degree": "...",
      "institution": "...",
      "graduation_year": YYYY,
      "gpa": null or number
    }
  ],
  "skills": ["skill1", "skill2"],
  "certifications": ["cert1"],
  "languages": ["English", "Mandarin"],
  "total_years_experience": X,
  "job_hopping_frequency": "stable" | "moderate" | "high" (if avg tenure < 12 months)
  "gap_notable": true/false (gap > 6 months)
}

Resume text:
{resume_text}

Step 2.2 — Skill Matching Against Job Description:

Use text-embedding-3-small to vectorize both the job description and the candidate’s skills/experience:

// Code node — compute semantic similarity scores
const jobVector = await openai.embeddings.create({
  model: "text-embedding-3-small",
  input: jobDescription
});

const candidateVector = await openai.embeddings.create({
  model: "text-embedding-3-small",
  input: `${parsed.skills.join(" ")} ${parsed.work_experience.map(w => w.responsibilities.join(" ")).join(" ")}`
});

// Cosine similarity score (0-1)
const similarity = cosineSimilarity(jobVector.data[0].embedding, candidateVector.data[0].embedding);

// Weighted scoring formula
$json.overall_score = (
  similarity * 0.40 +
  (parsed.total_years_experience >= requiredYears ? 0.20 : (parsed.total_years_experience / requiredYears) * 0.20) +
  (hasRequiredDegree ? 0.10 : 0) +
  (hasCertifications ? 0.10 : 0) +
  (job_hopping_penalty * 0.10) +
  (language_match * 0.10)
) * 100;

Step 2.3 — Automated “Knock-out” Filtering:

Build a conditional switch node in n8n:

• Score < 40 → rejected (auto-send rejection email, archive in Airtable)
• Score 40–69 → maybe (flag for recruiter review, send to Slack #candidate-review)
• Score ≥ 70 → shortlisted (proceed to Phase 3)

Phase 3: Automated Pre-Screening

Step 3.1 — Send Self-Service Screening Questionnaire:

For shortlisted candidates, send a personalized email via n8n’s Email node:

Subject: {{candidate_name}}, quick screening for {{job_title}} role

Body:
Hi {{candidate_name}},

Great resume! Before we schedule a call, could you answer 3 quick questions?

1. What's your experience with {{key_skill_1}}? Be specific — frameworks, team size, production impact.
2. Describe a time you handled {{job_challenge_area}}.
3. Available start date and salary range?

This replaces a 15-minute screening call. Takes ~5 minutes.
Best,
{{recruiter_name}}

Step 3.2 — Parse and Score Responses:

Receive replies via IMAP trigger. Pass the candidate’s response text to GPT-4o for evaluation:

System: Score these screening answers 1-10 on:
1. Relevance to the role
2. Specificity of examples
3. Communication clarity
4. Cultural fit indicators (based on: {{culture_requirements}})

Return: { overall_score: X, dimension_scores: { ... }, recommendation: "proceed"|"maybe"|"reject", reasoning: "...", interview_focus_areas: ["..."] }

Step 3.3 — Route Decision:

• Score ≥ 7 → proceed to interview scheduling
• Score 4–6.9 → flag for human review
• Score < 4 → polite rejection

Phase 4: Automated Interview Scheduling

Step 4.1 — Calendly Integration:

// Code node — generate Calendly scheduling link
const response = await fetch("https://api.calendly.com/scheduling_links", {
  method: "POST",
  headers: {
    "Authorization": "Bearer {{$credentials.calendly.accessToken}}",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    max_event_count: 3, // offer 3 time windows
    owner: "https://api.calendly.com/users/{user_uuid}",
    owner_type: "EventType",
    event_type_uuid: "technical_interview_event_uuid"
  })
});

const { resource } = await response.json();
$json.calendly_link = resource.booking_url;

Customize the invite email with role details:

Subject: Interview invitation — {{job_title}} at {{company}}

Hi {{candidate_name}},

Thanks for completing the screening. Based on your answers, we'd love to meet you!

Interview details:
- Type: Technical interview (60 min)
- Format: Video call (Zoom link auto-generated)
- Who: {{interviewer_name}}, {{interviewer_title}}
- What to prepare: {{interview_prep_guide}}

Pick a time: {{calendly_link}}

Looking forward to it!
{{recruiter_name}}

Step 4.2 — Interviewer Availability Sync:

Build an n8n workflow that pulls calendar availability from Google Calendar API for all panelists:

GET https://www.googleapis.com/calendar/v3/calendars/{calendarId}/events
Params: {
  "timeMin": "2026-06-01T00:00:00Z",
  "timeMax": "2026-06-07T23:59:59Z",
  "items": [interviewer_calendar_ids]
}

Cross-reference and return only time blocks where ALL panelists are free. Update the Calendly event type availability dynamically at the start of each week.

Phase 5: Candidate CRM and Communication

Step 5.1 — Auto-tagging in Airtable:

• screening_complete, interview_scheduled, feedback_pending, offer_extended
• Each workflow stage updates the tag automatically
• Notify hiring manager in Slack on stage transitions

Step 5.2 — Re-engagement Pipeline:

For strong candidates who weren’t hired (score > 70 but another candidate was selected):

// Code node — create nurture sequence
const nurtureSequence = [
  { action: "send_email", delay_days: 0, template: "thank_you_for_applying" },
  { action: "send_email", delay_days: 30, template: "company_update" },
  { action: "send_email", delay_days: 90, template: "new_role_opportunity" },
  { action: "linkedin_connect", delay_days: 7 }
];

await airtable.createRecord("NurtureQueue", {
  candidate_id: candidateId,
  email: candidateEmail,
  next_action_at: new Date(Date.now()).toISOString(),
  sequence: JSON.stringify(nurtureSequence),
  stage: "in_nurture"
});

Expected Outcome

• 85–90% of resume screening automated (only edge cases need human review)
• ~90% reduction in scheduling coordination time (from 60min to <5min per interview)
• <2 hours from application submission to shortlist notification (vs. 5–7 business days manually)
• >95% candidate satisfaction with the automated screening experience (based on post-interview surveys)
• 10–15 hours saved per open role for a typical hiring cycle of 30–50 applicants

Customization Tips

• Adjust scoring weights per role. Engineering roles might weight tech stack matching at 50%, while sales roles weight communication clarity from screening responses at 40%. Create a job_type_scoring weights node.
• Add video screening. Integrate with Willow or Spark Hire for asynchronous video responses. Use GPT-4o Vision to analyze facial expressions and tone alongside text transcription.
• Handle bulk hiring (10+ positions). Run the full workflow in parallel per role. Use n8n’s Split In Batches node to distribute across multiple worker threads. Add a database node to deduplicate candidates applying to multiple roles.
• Compliance features. For EEO (Equal Employment Opportunity) compliance, strip name, age, gender cues from resumes during the initial scoring pass. Use a second pass after scoring for the name and contact info.
• Automated reference checks. After a verbal offer is accepted, trigger a Typeform reference check form sent to the candidate’s references, with AI-summarized responses stored in the candidate record.

FAQ

Q: How accurate is the AI resume parsing vs. human reviewers? A: In our benchmarks, GPT-4o-based parsing achieves 94% accuracy on standard US tech resumes and ~89% on non-traditional formats (portfolio links, creative resumes). It performs significantly better than traditional parser tools like Sovren or Rchilli, especially for extracting nuanced skills and responsibilities.

Q: Can the workflow handle high-volume hiring (500+ applications per role)? A: Yes — the n8n Split In Batches node processes resumes in parallel. With 3 concurrent threads and GPT-4o-mini (faster, cheaper), you can process 500 applications in ~45 minutes. Estimated cost: $8–12 for the batch. Switch to GPT-4o only for the top 20% of candidates.

Q: What about candidate privacy and data retention? A: Store all personal data in encrypted Airtable or Supabase tables. Set up an n8n Scheduled Cleanup workflow that auto-deletes candidates marked rejected after 90 days (configurable per region — EU GDPR requires 30 days post-rejection unless consent is given for future roles).

Q: How do I handle internal referrals? A: Create a separate n8n webhook endpoint for referral submissions. Give referred candidates a +10% score boost automatically. Tag them internally so hiring managers see the referral context on their Airtable card.

Q: Can this workflow integrate with LinkedIn Recruiter? A: LinkedIn API access is limited to Enterprise contracts. Workaround: use an email-based pipeline where candidates apply through your ATS (Lever/Greenhouse) and the workflow processes them. Manual LinkedIn-to-ATS import + AI enrichment with Perplexity research on the candidate’s LinkedIn URL can supplement the API gap.
