Job descriptions contain more information than meets the eye. Between the lines are clues about company culture, real priorities, and exactly what keywords your resume needs. AI can help you decode all of this in minutes.

🎯 What AI Can Extract from Job Descriptions

  • Hard Skills: Technical requirements and tools
  • Soft Skills: Communication, leadership, teamwork expectations
  • Keywords: Exact phrases for ATS optimization
  • Culture Signals: Values and work environment clues
  • Priority Ranking: What matters most to the employer

Step 1: Initial Analysis Prompt

Start with this comprehensive prompt to get a full breakdown:

Master Analysis Prompt

Analyze this job description thoroughly:

[PASTE FULL JOB DESCRIPTION]

Provide:

**1. MUST-HAVE Requirements** (deal-breakers)
- List each requirement with confidence level (explicit vs implied)

**2. NICE-TO-HAVE Qualifications** (bonus points)
- Items that would strengthen candidacy but aren't required

**3. KEYWORDS FOR RESUME** (exact phrases)
- Technical skills
- Tools/platforms/software
- Certifications
- Industry terminology
- Action verbs they use

**4. SOFT SKILLS EXPECTED**
- Read between the lines

**5. COMPANY CULTURE SIGNALS**

- What work environment does this suggest?

**6. RED FLAGS OR CONCERNS**
- Anything unusual or potentially concerning

Step 2: Keyword Extraction

For ATS optimization, you need exact keyword matches. Use this prompt:

Keyword Extraction Prompt

Extract every keyword and phrase from this job description that should appear on a tailored resume:

[PASTE JOB DESCRIPTION]

Organize into categories:
1. **Technical Skills** (programming languages, frameworks, etc.)
2. **Tools & Platforms** (software, systems)
3. **Certifications** (any mentioned or implied)
4. **Methodologies** (Agile, Scrum, Six Sigma, etc.)

6. **Industry Terms** (jargon specific to this field)
7. **Action Verbs** (verbs they use repeatedly)

Include frequency count if terms appear multiple times.

Step 3: Decode Hidden Expectations

What they write isn't always what they mean. This prompt helps decode the subtext:

Decode common euphemisms like:
- "Fast-paced environment"
- "Self-starter"
- "Wear many hats"

- "Work hard, play hard"
- "Looking for a rockstar"

What is this employer really looking for? What's the work culture likely to be?

Step 4: Match Analysis

Once you've analyzed the JD, compare it against your background:

Fit Analysis Prompt

Compare my background to this job description:

**Job Description:**
[PASTE JD]

**My Background:**
[PASTE RESUME OR SUMMARY]

Assess:
1. **Match Score** (0-100%) with explanation
2. **Strong Matches** - requirements I clearly meet
3. **Partial Matches** - requirements I meet with translation
4. **Gaps** - requirements I don't obviously meet
5. **Unique Value** - things I bring that aren't listed but could be valuable

For each gap, suggest how I might address it on my resume.

My experience: [BRIEF SUMMARY]
