Why Your Job Description Should Never Exceed 600 Words

The 600-Word Rule That Changed Corporate Hiring

When Microsoft cut their average job description from 850 to 527 words in 2019, applications increased by 42% within 90 days. Not just more applications - better ones. Candidates with 8+ years of experience were 35% more likely to complete the application process.

The reason? Cognitive load. Your brain can only process so much information before it starts skipping, scanning, or abandoning entirely. For job seekers scrolling through dozens of postings on mobile devices during lunch breaks or commutes, anything over 600 words is a commitment they will not make.

Why Long Job Descriptions Repel Your Best Candidates

Top performers are not unemployed - they are passively browsing. They have 4 minutes, not 14. When your [Senior Software Engineer](/job-description/senior-software-engineer-general) posting runs 1,200 words with paragraphs about company history, your 'nice-to-haves' section with 18 bullet points, and redundant language about being a 'team player,' you have already lost them.

Research from TalentWorks analyzed 4 million job postings and found the sweet spot: 450 to 600 words generate the highest application rates across all experience levels. Go under 300 words, and candidates assume the role is not real or is commission-only sales. Exceed 750 words, and mobile completion rates drop by 52%.

Here is what happens at different word counts:

• Under 300 words: 28% fewer applications, perceived as low-effort or spam
• 300-450 words: Strong performance, but may lack critical details for senior roles
• 450-600 words: Optimal zone - maximum applications with highest candidate quality
• 600-900 words: 31% drop in mobile completions, 40% higher bounce rate
• Over 900 words: Seen as bureaucratic, loses passive candidates entirely

The Brutal Edit: What to Cut First

Most hiring managers panic at 600 words. 'How do I fit everything?' You do not. You prioritize ruthlessly.

Cut immediately:

• Company history unless you are a startup explaining what you do
• Overused phrases: 'fast-paced environment,' 'wear many hats,' 'hit the ground running'
• Redundant requirements (if you need Excel skills for a [Data Analyst](/job-description/data-analyst-general) role, it is implied)
• Laundry lists of soft skills
• Legal boilerplate in the body (move to footer)

Keep and sharpen:

• 3-5 core responsibilities written as achievements, not tasks
• 5-7 must-have requirements (not 15 'nice-to-haves')
• Salary range or band (boosts applications by 43%)
• One paragraph on growth opportunity
• Concrete team structure (who they report to, who reports to them)

The Formula Used by Fortune 500 Recruiters

Apple, Google, and Amazon average 510 words in their job descriptions. Here is their structure:

Opening (50-75 words): What the role does and why it matters

Responsibilities (150-200 words): 3-5 bullet points focused on impact, not tasks

Requirements (150-200 words): Must-haves only, with years of experience clearly stated

About the team (75-100 words): Real context about collaboration and reporting structure

Compensation and benefits (50-75 words): Salary range, equity, standout perks

Total: 475-650 words

Notice what is missing? Paragraphs about your ping pong table. Five sentences about your 'collaborative culture.' A requirements section that reads like a fantasy sports draft.

Mobile Is Not Optional Anymore

68% of job searches now happen on mobile devices. Your 900-word [Project Manager](/job-description/project-manager-general) description with dense paragraphs is unreadable on a phone screen. Candidates are literally pinching and zooming to parse your requirements - then giving up.

Short paragraphs (2-3 sentences max), bullet points, and white space are not stylistic choices. They are accessibility requirements.

The 10-Minute Audit

Pull your three most recent job postings. Run them through a word counter. If any exceed 600 words, you now have a conversion problem, not a candidate problem.

Edit them down using the Fortune 500 formula above. Repost. Track your application rates for 2 weeks.

Most recruiters see a 25-35% increase in qualified applicants just by cutting the fluff. Your best candidates are not ignoring you because they are not qualified. They are ignoring you because they are busy - and you are asking them to read a novella to apply for a job.
