The 10-80-10 rule and the role of AI in recruitment

Table of contents

Recruiting used to be *a lot* of instinct, hustle, and handwritten notes. But in 2025, that’s no longer enough.

Hiring today demands a process. One that’s repeatable, consistent - and smart.

And at the heart of it all? AI in hiring.

We’re not just talking about job boards and interviews. We’re talking about:

  • Automating what slows you down
  • Personalizing what matters (& making it relevant) 
  • And using tools that help you hire better (not just faster) 

Enter the 10-80-10 rule.

It’s a framework that’s helping forward-thinking hiring teams make better use of their time - and of AI in hiring.

In this article, we’ll break down:

  • What the 10-80-10 principle is (and how it works)
  • Real-world examples of recruiters using AI in hiring
  • How AI fits into the middle 80%
  • Where human oversight still matters
  • What to automate (and what not to)
  • Why this matters for the future of your ATS
  • And what tools like Quil are doing to help

Let’s start. 

But First: What’s the 10-80-10 Rule, Anyway?

You might’ve heard of the 10-80-10 rule in leadership, where the idea is to focus most of your time on the high-performers (top 10%) and low-performers (bottom 10%), while managing the middle 80% with consistency and guidance.

But in the AI context, it looks a little different. Here’s how the principle gets reimagined for hiring:

  • The first 10%: You define the structure. Think job description, scorecard, or interview plan.
  • The middle 80%: Let AI handle the heavy lifting… admin, summaries, formatting, ATS updates, document generation, etc.
  • The final 10%: You bring the human touch. You personalize, add judgment, and make the final call.

This rule helps recruiters focus their energy where it counts. You don’t need to do everything… just the parts that require your expertise.

What are Recruiters Actually Automating Today?

According to LinkedIn’s Future of Recruiting report, 73% of hiring decision-makers say that AI will change how organizations hire. And it’s already happening. 

AI doesn’t just save time (by 20% - which is a whole day's work saved) it also brings along other benefits. 

  • 33% agree it increases the quality of hires
  • White 37% say it improves the candidate’s experience
  • 70% say it improves hiring efficiency, and 47% agree that it helps with job postings’ effectiveness. 

And that’s exactly what tools like Quil are doing.

Ryan and Josh share how one agency recruiter used Quil’s # AI recruiting assistant to: 

  • Record interviews
  • Compare candidates objectively (even across weeks)
  • Eliminate recency bias
  • Stack-rank talent without second-guessing
  • And save up to 8+ hours every week

Because when you’re running back-to-back interviews, having the ability to listen again is an absolute game-changer. 

So you’re not making decisions on vague gut feelings. You can make decisions based on facts - go back, analyze, and make clarity-based decisions. 

Why does the first 10% matter so much?

Because AI is only as smart as the input you give it. Simple. 

It will get smarter in the future, but that’s not happening for a while. Or this year at least (with AI advancing every day - there’s not a certain timeline you can give on things) 

Here’s an example one of our agency recruiter teams shared with us: 

They used prompts to generate DISC-style personality insights from interviews, then ran the prompts three times. 

It delivered the exact same result each time. That made them realize how powerful AI can be when it’s structured well. 

So, whether you're creating candidate scorecards, prompting for summaries, or building job descriptions, your templates are your foundation. Your 10% defines the quality of the 80%.

What Are People Doing Wrong With AI in Hiring?

While AI is super powerful, it should not be used for everything. Recruiters get excited, of course. It’s new. It’s efficient. And it feels like magic. 

But that excitement can sometimes be detrimental. Because then recruiters start relying entirely on it. And that’s where things go wrong. 

One example: using AI to write candidate summaries based on resumes alone (without factoring in actual interview performance). 

The summary may look fine, but if it doesn't match how the candidate presented themselves in conversation, it could derail the process later.

Here’s a common scenario:

  • A recruiter pastes a resume and job description into ChatGPT
  • They ask for a matching summary or submittal
  • It looks good, so they send it off without edits
  • A hiring manager calls out something that was never discussed - or flat-out wrong

And that’s the missing 10% at the end - the human touch that needs to be there to elevate what AI creates. 

A few simple steps to fix this: 

  • Use AI to draft, not to decide
  • Always fact-check summaries against your own notes
  • Layer in insights from actual conversations (not just resumes)
  • Ask AI to highlight any new claims it introduces, so you can review quickly

And above all - read the thing.

Let’s look at a few other examples of where AI goes wrong in hiring. 

1. What Should You Stop Doing Manually?

Here are the top time-wasters AI can handle today:

  • Reformatting resumes
  • Writing submittals from scratch
  • Logging notes into your ATS
  • Summarizing interview calls
  • Creating candidate profiles

One executive recruiter shared how they often meet a candidate across 3–4 stages: screener, principal, managing director. 

Each person leaves notes. Rather than copy/pasting it all into a report, they use AI to combine everyone’s notes into a single candidate brief.

For exec search firms, this is gold.

2. The Resume Personalization Rabbit Hole

Another thing we’ve learned when working with hundreds of recruiters over the past 2 years: recruiters often manually rewrite resumes for candidates before submission, to align better with the job.

But that takes forever. So they’re now using AI to:

  • Scan a resume
  • Analyze the JD
  • Add matching language to show relevance

That’s 80% of the job done in seconds. But remember the final 10%: check for bloated claims, weird phrasing, or off-brand tone.

Because nothing screams “lazy” like a resume that says “synergistically leveraged paradigm shifts.”

3. Internal vs external recruiters: Where AI makes a difference

There’s always a debate that goes around when to hire in-house or when to work with external recruiting firms. Since Quil is explicitly built for recruiting agency firms, we can share a few insights (view the above podcast for more). 

  • For junior roles, especially with a strong brand (e.g., HubSpot), in-house sourcing works. Because you’re likely to receive lots of inbound applications - and your internal team can manage the workload. 
  • For senior roles, where network depth or regional reach is limited, external recruiters add the most value.
  • For niche roles, third-party recruiters help you find passive talent you wouldn't attract via a job board.

Plus, AI is shifting how both internal and external recruiters operate.

Internal teams are starting to use AI to:

  • Automate screening questions
  • Capture structured interview notes
  • Pre-fill candidate records in the ATS
  • Rewrite resumes or submittals to match job descriptions

External recruiters… especially those focused on executive search - are using AI to:

  • Detect IP address mismatches (to verify location accuracy)
  • Spot resume inconsistencies or copy-pasted applications
  • Personalize outreach messages at scale
  • Generate polished candidate profiles combining input from multiple stakeholders

In both cases, the goal is the same: to spend more time talking to top candidates (and less time stuck in repetitive, manual tasks.)

And it’s working. According to the 2024 Employ Recruiter Nation Report, over 55% of recruiters now use AI for candidate matching, and 44% use it for intelligent sourcing. 

That number is only going up.

4. What your ATS isn’t doing (yet)

Applicant tracking systems were never built for modern hiring workflows. Most are glorified databases.

They weren’t built to:

  • Auto-sync with interview tools
  • Tag and categorize notes
  • Format submittals
  • Pull in behavioral data

That’s why Quil is built to integrate with your favorite ATS - fill those gaps, and make your hiring workflow easier. 

So, How Do You Start Using The 10-80-10 Rule?

Here’s your cheat sheet:

First 10%:

  • Build a job scorecard
  • Outline candidate expectations
  • Structure your prompts (for summaries, resumes, JDs)

Middle 80% (AI zone):

  • Interview recordings
  • Summarizations
  • Submittals
  • Resume optimization
  • ATS updates
  • Candidate brief generation

Final 10%:

  • Personalize content
  • Add nuance
  • Validate accuracy
  • Polish presentation

Let the machines do what they do best. 

Then add the finishing touch that only you can bring.

Takeaway: AI Isn’t “Taking Sides” - It’s Empowering You. 

One thing you need to understand is: AI isn’t necessarily driving growth - it’s enabling efficiency.

Because your candidate pipeline doesn’t always have to be full. 

You can do more with less. 

Instead of adding headcount to handle:

  • Onboarding bottlenecks
  • Documentation
  • Interview tracking

You add AI to handle the load. Then hire only when it makes economic sense (and treat AI as an assistant). 

Use it to create cushion space to do what you’re actually great at: strategy, building trust, and making remarkable hires. 

In short: use AI as leverage. Use your brain for decisions.
