Why “Measure” Your Hiring Process?
The right hiring data is your roadmap to better results: it shows you where candidates drop out, which sources actually deliver top talent, and how long it really takes to move someone from application to offer.
Without these insights, you’re left guessing, and let’s be honest, guesswork just isn’t good enough.
Not to state the obvious here, but measuring your results is imperative, especially when you’ve made a big investment in new hiring software.
Here’s why:
- Prove ROI: When you can show exactly how your hiring tech is helping you fill roles faster, improve candidate quality, or save your team time, it’s much easier to justify the spend and keep your budget secure for next year.
- Get Budget for New Initiatives: Solid metrics make it easier to make your case for new tools, team members, or process improvements. Data-backed wins open doors for future investments.
- Earn a Strategic Voice in the Company: When you know your numbers and can explain what’s driving them, you become a true partner to leadership, not just the person who posts jobs and schedules interviews.
Key Hiring Metrics to Measure
When it comes to hiring, you can’t improve what you don’t measure.
So, what should you measure?
Let’s take a look.

Pre-Hire Metrics
These metrics help you understand and optimize every step before a candidate officially joins your team. They’re especially critical for organizations with evergreen roles and ongoing hiring needs.
Time-to-Hire
Time-to-hire measures the average number of days from when a candidate enters your pipeline (applies or is sourced) to when they accept your job offer.
To calculate it, you’d track the start date (application or sourcing) and the end date (offer acceptance) for each candidate. Then, calculate the average across all hires in a given period.
Time-to-Hire = Date of Offer Acceptance − Date of Application/Sourcing
You can track this manually in a spreadsheet or, better yet, automate it with hiring software that timestamps each stage.
Why measure it:
- Reveals bottlenecks in your process: are candidates stalling at the screening, interview, or offer stage?
- A shorter time-to-hire helps you secure top talent before competitors do; 57% of candidates lose interest if the process drags on.
- Directly impacts candidate experience and cost-per-hire (a.k.a. your ROI)
Time to hire/speed to hire is a super important metric we talk about a lot as it’s critical to bringing on high-quality talent into your organization, fast.
Cost-per-Hire
Cost-per-hire is the total expense incurred to fill a position, including advertising, recruiter time, technology, assessments, and onboarding.
That’s a lot of factors. To get the total, add up all internal and external recruiting costs for a period, then divide by the number of hires made.
Cost-per-Hire = Total Recruiting Costs/Number of Hires
Remember to include job board fees, recruiter salaries, technology subscriptions, background checks, and any other related expenses.
You should measure this because it:
- Helps you optimize your recruiting budget and prove ROI on your hiring technology.
- Identifies which roles or sources are most expensive to fill.
- Enables more accurate workforce planning and forecasting.
This number can be super enlightening, especially for roles you fill often, like evergreen positions or in instances of high-volume hiring. Sometimes, simple fixes, like automated screening tools or behavioral assessments, can help reduce this number, which will look really good on your bottom line.
Candidate Conversion Rates Through Each Hiring Stage
This metric tracks the percentage of candidates who move from one stage of your hiring funnel to the next: application, screening, interviews, offer, and acceptance.
You can get this number by calculating the ratio of candidates advancing at each step. For example, if 100 apply and 20 are interviewed, your applicant-to-interview conversion rate is 20%.
Stage Conversion Rate = Number of Candidates Who Advance/Number of Candidates at Previous Stage×100
This metric is important because it:
- Pinpoints where candidates drop out or get stuck.
- Helps you refine your process and improve candidate experience.
- Reveals if your job descriptions, screening, or interviews are too strict (or too loose).
For example, say you notice that a super small percentage of your applicants make it to the interview stage (well below industry benchmarks). You might simplify your application and screening process, update the job description, or add in more “mini-gates” to increase that conversion rate.
Offer Acceptance Rate
Offer acceptance rate tracks the percentage of candidates who say “yes” to your job offers. It’s a direct reflection of how well your process, compensation, and employer brand are resonating with top talent.
To calculate it, divide the number of accepted offers by the total number of offers extended, then multiply by 100.
Offer Acceptance Rate = (Number of Offers Accepted / Number of Offers Extended) × 100
Why measure it?
- A high acceptance rate means your offers are competitive and your candidate experience is strong.
- A low rate can signal issues with salary, benefits, culture fit, or even slow offer processes.
- It’s a fast way to spot disconnects between what candidates want and what you’re offering.
Imagine you’re regularly losing out on candidates at the finish line. By tracking this metric, you might discover your salary bands are below market or your offer process is taking too long, giving you a clear place to start improving.
Source Quality Metrics
Source quality metrics help you pinpoint which channels — job boards, referrals, social media, recruiters — bring in your best candidates, not just the most.
It’s not just about volume; it’s about value. Track where your strongest hires come from by tagging sources and following candidates through to hire and beyond.
Measuring the source:
- Helps you invest in the sources that actually deliver high-quality, long-term employees.
- Identifies underperforming channels so you can reallocate budget and effort.
- Especially valuable for evergreen roles, where ongoing hiring makes efficiency critical.
Suppose you notice that employee referrals consistently lead to hires who stay longer and ramp up faster than those from job boards. That’s a sign to double down on your referral program and rethink your job board spend.
Diversity of Candidate Pool
Diversity of candidate pool measures the representation of different backgrounds, identities, and experiences among your applicants. For organizations committed to building inclusive, representative teams, this metric is essential.
Track diversity data (where legally permissible) at each stage of your pipeline to see how well you’re attracting and advancing candidates from underrepresented groups.
Keeping track of diversity:
- Ensures your sourcing strategies are reaching a wide, representative audience.
- Helps identify and address potential hiring bias or barriers in your process.
- Supports your organization’s DEI goals and strengthens your employer brand.
For example, if you see your candidate pool isn’t as diverse as your community or customer base, you might expand your sourcing to new job boards, community groups, or partnerships focused on underrepresented talent.
Interview-to-Hire Ratio
Interview-to-hire ratio measures how many candidates you need to interview to make a single hire. It’s a key efficiency metric, especially for high-volume or evergreen hiring.
Calculate it by dividing the total number of interviews conducted by the number of hires made in a given period.
Interview-to-Hire Ratio = Number of Interviews Conducted / Number of Hires
Why measure it?
- A high ratio could mean your screening process isn’t filtering enough, or your interview criteria are unclear.
- A low ratio suggests your process is efficient and you’re bringing the right people to the table.
- Saves your team time and ensures candidates aren’t being put through unnecessary rounds.
Imagine your team is interviewing ten people for every one hire in a high-volume role. By tightening up your screening or using one-way video interviews, you could reduce that time, saving hours and improving the candidate experience.
Post-Hire Metrics
Pre-hire metrics show how well your process works on the front end, but post-hire metrics reveal the true impact of your hiring decisions.
Quality of Hire
Quality of hire measures how well new employees perform and fit within your team after they’re onboarded.
It’s often tracked through a mix of performance reviews, ramp-up speed, and even retention rates.
You’ll want to measure this to:
- Shows if your hiring process is bringing in people who succeed and stick around.
- Helps you refine your sourcing, screening, and interviewing to focus on what actually predicts success.
- Directly ties your hiring efforts to business outcomes.
Say you notice that hires from one particular source consistently outperform others in their first year. That’s a cue to invest more in that channel and revisit your criteria for other sources.
Early Turnover Rate
Early turnover rate tracks the percentage of new hires who leave within their first year (or even first 90 days). It’s a red flag metric for issues with onboarding, culture fit, or unrealistic job previews.
Early Turnover Rate = (Number of New Hires Who Leave Within 1 Year / Total New Hires) × 100
Even though this is an unfortunate situation, you have to track it because:
- High early turnover is costly and disruptive, especially in people-powered organizations.
- Helps you spot gaps in onboarding, training, or candidate expectations.
- Drives improvements in both recruiting and retention strategies.
Suppose you find your early turnover rate is climbing. You might review your onboarding process, clarify job expectations, or provide more support during those critical first months.
Candidate Experience Ratings
Candidate experience ratings capture feedback from applicants about your hiring process. This can include surveys, Net Promoter Scores (NPS), or even informal feedback.
Measuring candidate experience is important because:
- A positive candidate experience boosts your employer brand and increases the likelihood that top candidates will accept your offers.
- Negative experiences can deter future applicants and even impact your reputation with customers.
For example, if feedback shows candidates feel left in the dark about their application status, you might implement automated updates or clearer communication touchpoints.
Hiring Manager Satisfaction Scores
You want to collaborate with your hiring managers more, right?
Well, hear from them and learn more about how happy your internal stakeholders are with the hiring process and the quality of candidates they receive.
Measuring hiring manager satisfaction:
- Ensures alignment between recruiting and the teams you support.
- Highlights areas where process improvements or better collaboration are needed.
- Critical for cross-functional organizations where hiring success depends on teamwork.
For example, if your hiring managers report frustration with slow candidate pipelines, identify process tweaks or additional support that will make everyone’s job easier.
Time Spent Per Hire by Hiring Team Members
This metric tracks the total hours your team spends to make each hire, from screening to interviews to onboarding. It’s especially valuable for professional services, consulting, or any business where time is literally money.
Why measure it?
- Helps you identify stages that eat up the most time and find ways to streamline.
- Frees up your team for higher-value work and reduces burnout.
- Supports resource planning and demonstrates the ROI of automation tools.
Suppose you realize your team is spending 15 hours per hire just on initial screenings. By introducing automated video interviews or smarter scheduling tools, you could cut that in half and redirect those hours to client work or strategic projects.
Tracking both pre-hire and post-hire metrics gives you a complete picture of your hiring process. When you know what’s working (and what’s not), you can make smarter decisions, prove your impact, and build a hiring strategy that truly moves your organization forward.
