Data-Driven Recruiting: How data leads to better hiring decisions
- Data-Driven Recruiting
- People Analytics
- Recruiting metrics
Data-Driven Recruiting means basing personnel decisions on solid data instead of pure intuition – from channel selection to candidate choice to backfilling roles. The goal is a faster, more objective, and fairer process. According to a survey at the HR Inside Summit 2024, around 60 percent of HR managers are already using data analysis. The key remains: Data supports the decision – the final choice is made by a person.
What is Data-Driven Recruiting?
Data-Driven Recruiting describes an approach in which companies use selected data for their staffing decisions—aiming for a more efficient and objective recruiting process. Rather than relying solely on experience and intuition, decisions are backed by metrics and analyses: Which channels deliver suitable applications? Where do we lose candidates in the process? What is the cost of an unfilled position?
The right expectation is essential: Data does not replace the judgment of experienced recruiters, it sharpens it. It makes visible what would otherwise remain hidden and makes decisions transparent. The actual selection—who fits the team and the role—remains a human decision.
Data is not automatically value-neutral
Metrics appear objective, but they are not inherently so: They always reflect the past and the way they were collected. Uncritically adopting data risks perpetuating existing patterns and biases rather than correcting them.
How prevalent is data-driven recruiting?
Data-driven practices have arrived in HR. In a survey at the HR Inside Summit 2024 (253 participants), around 60 percent reported already working with data analysis. Most frequently, the data is used for recruiting performance (about two-thirds), followed by identifying training needs (about half) and salary analyses.
The broader DACH benchmark also confirms the trend: According to the DGFP study "Recruiting Structures 2025," recruiting is becoming more structured, technological, and data-driven. Around two-thirds of companies now have their own recruiting department, and about half engage in strategic workforce planning. At the same time, the study reveals a gap: A significant portion of companies lacks personnel for Active Sourcing, even though active outreach is effective in a tight market.
Which metrics truly count?
Not every easily gathered number is meaningful. The following metrics form a solid foundation—what matters is linking them to a goal and not viewing them in isolation.
- Time-to-Hire / Time-to-Fill: How long does it take from application or job posting to offer acceptance? An early indicator of process speed.
- Cost-per-Hire: Average cost of a hire—helps direct budgets to effective channels.
- Quality-of-Hire: Quality of hire, e.g., via probationary success, performance, and retention—the most important but hardest to measure metric.
- Channel-Effectiveness: Which channel delivers not just a lot, but the right applications?
- Cost-of-Vacancy: What is the daily cost of an unfilled position in terms of lost value creation?
- Candidate Experience / Dropout Rate: Where and why do candidates drop out of the process?
Measure what matters—not what's easy
The DGFP study 2025 shows a typical imbalance: Time-to-Hire is used by about three-quarters of companies, but fewer than half consider it truly relevant. Conversely, over half consider the cost of unfilled positions important—yet less than ten percent measure it. The lesson: Choose a few metrics that match your goals rather than many that are simply easy to obtain.
Where does the data come from?
Most relevant data is already generated during ongoing operations—it just needs to be consolidated and evaluated.
- Application and process data from the applicant tracking system (ATS): origin, progress, dropout points.
- Application behavior: Which ads and channels generate how many suitable applications?
- Market data: Salary ranges, availability of qualifications, regional constraints (e.g., AMS shortage occupation list).
- Turnover and retention data: Where and why do people leave the company?
- Employee and candidate surveys: Qualitative signals about satisfaction and expectations.
Become data-driven in six steps
Define questions
The starting point is not the tool but the question: What do you want to improve—speed, quality, cost, or fairness?
Establish a few key metrics
Choose three to five metrics that directly contribute to your goals. Better a few that truly count.
Centralize data
Bring applicant, channel, and market data together in one place—usually in the ATS—rather than leaving them in isolated solutions.
Analyze and visualize
Regularly evaluate the data and visualize it in a way the team understands and uses.
Derive and test actions
Derive specific actions (e.g., change channels, shorten process) and assess their impact.
Continuously evaluate
Data-Driven Recruiting is not a project; it is a cycle: measure, act, measure again.
The greatest lever is often not technology, but competence: People Analytics, a basic understanding of data, and a willingness to base decisions on insights. These skills can be built up gradually—you don't need to start with everything at once.
Limits: Data protection, bias, and the human factor
Candidate data is sensitive personal information. Data-driven recruiting must be designed to be GDPR-compliant from the start: purpose limitation, data minimization, transparency for those affected, and clear deletion deadlines. Anything not required for the specific position will not be collected.
Additionally, there is the legal framework for automated systems: The EU AI Act classifies AI that participates in recruiting processes like selection and applicant ranking as high-risk. This requires traceability, documentation, and effective human oversight. Any model that sorts without oversight is neither permissible nor desirable.
Data as Autopilot
An algorithm automatically filters applications; no one checks the patterns used. Existing biases are unintentionally reinforced.
Data as a compass
Data provides the preselection and justification; a human makes the decision, considering context, fairness, and exceptions (human-on-the-loop).
How voccess operates data-based
At voccess, we combine data-based matching with the judgment of experienced senior recruiters. Our Deep Match process aligns candidates with the requirements profile professionally, culturally, and motivationally—not just by keywords. Every step is documented and sensitive to discrimination; the final decision is always made by a human. This way, we combine the speed and objectivity of data with the responsibility a personnel decision requires.
Frequently Asked Questions
Data-Driven Recruiting is the overarching term: decisions are based on data and metrics. AI recruiting is a subset where algorithms recognize patterns or make suggestions. You can work data-driven even without AI—a thoroughly evaluated applicant management system is already a big step.
Start with the metric that addresses your biggest problem. If filling a position takes too long, Time-to-Hire and dropout points in the process are the right place to start. If it’s about quality, look at probation period success and retention. It’s important to start with a few, clearly defined metrics.
No. Even small companies continuously generate data in recruiting. You can start without expensive software: consistent analysis of application sources and dropout points in the existing process leads to better decisions—the size of the company is secondary.
By collecting data only for specific purposes and minimally, ensuring the process is transparent and documented, and leaving the decision to a human. Automated selection systems also fall under the EU AI Act (high-risk) and require effective human oversight. This information does not replace legal advice.

Skills shortage in Austria: What companies can do now
The skills shortage in Austria is not a temporary bottleneck but a demographic permanence: More people are leaving the workforce than entering it. Companies that continue to only post ads and wait for applications will lose – active engagement is needed, along with a swift process, a credible employer profile, and the willingness to develop career changers.

Active Sourcing or job ad: When each approach pays off
The job ad reaches actively searching individuals and works well for well-known brands and roles with a strong candidate pool. Active Sourcing – directly, personally approaching suitable individuals – is the way for hard-to-fill, specialized, or confidential positions, and for the large group not actively seeking. In practice, a combination of both nearly always wins.
