Funky graphs & charts

In the fast-paced world of human resources, data analytics has become an invaluable tool for optimizing recruitment and selection processes. By leveraging analytics, HR professionals can gain valuable insights into their hiring practices, identify areas for improvement, and make data-driven decisions to attract and retain top talent. In this comprehensive guide, we'll explore the key analytics related to the recruitment and selection process and how they can be utilized to enhance HR effectiveness.


1. Time-to-Fill

Time-to-fill is a critical metric that measures the time it takes to fill a job vacancy from the moment it is posted to the moment a candidate is hired. Analyzing time-to-fill data can help HR professionals identify bottlenecks in the recruitment process, assess the efficiency of their sourcing methods, and set realistic hiring timelines. By reducing time-to-fill, organizations can minimize the impact of vacancies on productivity and ensure a steady flow of qualified candidates into the workforce.


Calculation: Time-to-Fill = (Date of Hire - Date Job Posted)

Example: If a job was posted on January 1st and the candidate was hired on February 1st, the time-to-fill would be 31 days.


2. Cost-per-Hire

Cost-per-hire is another essential metric that quantifies the total cost incurred to fill a job vacancy. This includes expenses related to job postings, advertising, recruitment agencies, and employee referrals, among others. Analyzing cost-per-hire data enables HR professionals to evaluate the effectiveness of their recruitment strategies, identify cost-saving opportunities, and allocate resources more efficiently. By minimizing cost-per-hire, organizations can optimize their recruitment budget and achieve better returns on investment.


Calculation: Cost-per-Hire = (Total Recruitment Costs / Number of Hires)

Example: If a company spent $10,000 on recruitment efforts and hired 5 employees, the cost-per-hire would be $2,000.


3. Quality of Hire

Quality of hire is a measure of the performance and contribution of new hires to the organization. While more challenging to quantify than other metrics, analyzing quality of hire data allows HR professionals to assess the effectiveness of their selection process and the suitability of candidates for the job role. By tracking performance metrics, such as job performance ratings, retention rates, and productivity levels, organizations can identify trends and patterns among high-performing hires and replicate success in future recruitment efforts.


Calculation: Quality of Hire can be assessed through various metrics such as:

  • Job Performance Ratings

  • Retention Rates

  • Productivity Levels

Example: If a company hires 10 employees and after one year, 8 of them are still employed with high-performance ratings, the quality of hire would be 80%.


4. Applicant Source Effectiveness

Applicant source effectiveness measures the success rate of different recruitment sources in attracting qualified candidates. By tracking the source of applicants and monitoring their progression through the recruitment process, HR professionals can identify which sourcing channels yield the highest-quality candidates and allocate resources accordingly. Analyzing applicant source effectiveness data enables organizations to optimize their recruitment advertising strategies, focus on the most effective channels, and maximize the return on investment in recruitment marketing efforts.


Calculation: Applicant Source Effectiveness = (Number of Hires from Source / Total Number of Applicants from Source) × 100

Example: If a company receives 100 applicants from a job board and hires 5 of them, the applicant source effectiveness for that job board would be 5%.


5. Candidate Experience

Candidate experience metrics assess the satisfaction and engagement levels of candidates throughout the recruitment process. This includes factors such as the ease of application, communication with recruiters, interview experience, and overall impression of the organization. Analyzing candidate experience data allows HR professionals to identify pain points in the recruitment process, improve communication and engagement with candidates, and enhance the employer's brand reputation. By prioritizing candidate experience, organizations can attract top talent, promote positive word-of-mouth referrals, and strengthen their employer brand in the competitive talent market.


Calculation: Candidate Experience can be measured through surveys or feedback forms. A simple rating scale or Net Promoter Score (NPS) can be used to assess candidate satisfaction.

Example: If a company surveys 100 candidates and 80% of them rate their overall experience as positive (on a scale of 1 to 10), the candidate experience score would be 80%.


6. Offer Acceptance Rate

The offer acceptance rate measures the percentage of job offers extended by the organization that are accepted by candidates. This metric helps HR professionals assess the attractiveness of the organization as an employer and the effectiveness of their recruitment process in attracting and retaining top talent.


Calculation: Offer Acceptance Rate = (Number of Accepted Offers / Number of Offers Extended) × 100

Example: If a company extended job offers to 20 candidates, and 15 of them accepted the offers. Offer Acceptance Rate = (15 / 20) × 100 = 75%


7. Time-to-Start

Time-to-start measures the time it takes for a new hire to start working after accepting the job offer. This metric helps HR professionals evaluate the efficiency of their onboarding process and identify any delays or obstacles that may affect the candidate's start date.


Calculation: Time-to-Start = (Date of Start - Date of Offer Acceptance)

Example: After accepting a job offer, a candidate starts working after 30 days.

Time-to-Start = 30 days


8. Candidate Conversion Rate

Candidate conversion rate measures the percentage of candidates who progress through each stage of the recruitment process, from application to hire. This metric helps HR professionals assess the effectiveness of their screening and selection criteria and identify areas for improvement in the candidate journey.


Calculation: Candidate Conversion Rate = (Number of Hires / Number of Applicants) × 100

Example: Out of 200 applicants, 10 candidates were hired.

Candidate Conversion Rate = (10 / 200) × 100 = 5%


9. Application Completion Rate

The application completion rate measures the percentage of candidates who complete the application process after starting it. This metric helps HR professionals evaluate the user experience of their online application system and identify any barriers or challenges that may discourage candidates from completing their applications.


Calculation: Application Completion Rate = (Number of Completed Applications / Number of Started Applications) × 100

Example: 200 candidates started the application process, but only 150 completed it.

Application Completion Rate = (150 / 200) × 100 = 75%


10. Diversity Metrics

Diversity metrics assess the representation of diverse candidates in the recruitment process, including factors such as gender, ethnicity, age, and disability status. These metrics help HR professionals track progress toward diversity and inclusion goals, identify areas for improvement, and ensure fairness and equity in the hiring process.


Gender Diversity

Gender diversity measures the representation of male and female candidates in the recruitment process.

Calculation: Gender Diversity = (Number of Female Candidates / Total Number of Candidates) × 100

Example: If out of 200 candidates, 80 are female, the gender diversity would be (80 / 200) × 100 = 40%.


Ethnic Diversity

Ethnic diversity measures the representation of candidates from different ethnic or racial backgrounds.

Calculation: Ethnic Diversity = (Number of Minority Candidates / Total Number of Candidates) × 100

Example: If out of 200 candidates, 60 are minorities, the ethnic diversity would be (60 / 200) × 100 = 30%.


Age Diversity

Age diversity measures the representation of candidates from different age groups.

Calculation: Age Diversity = (Number of Candidates in Age Group / Total Number of Candidates) × 100

Example: If out of 200 candidates, 50 are between the ages of 18-30, the age diversity would be (50 / 200) × 100 = 25%.


Disability Diversity

Disability diversity measures the representation of candidates with disabilities.

Calculation: Disability Diversity = (Number of Candidates with Disabilities / Total Number of Candidates) × 100

Example: If out of 200 candidates, 10 have disclosed disabilities, the disability diversity would be (10 / 200) × 100 = 5%.



In conclusion, HR analytics play a crucial role in optimizing the recruitment and selection process, enabling organizations to attract, assess, and retain top talent effectively. By leveraging key analytics such as time-to-fill, cost-per-hire, quality of hire, applicant source effectiveness, and candidate experience, HR professionals can gain valuable insights into their hiring practices, identify areas for improvement, and make data-driven decisions to drive organizational success in the competitive talent market.
