Recruitment Funnel: How to Measure Recruiting Performance

A recruitment funnel has 6 stages, each with numbers that show where it leaks. HR teams that read the funnel cut hiring costs and keep new hires longer.

Many HR teams in Thailand know how many hires they close each month, but not what happens along the way: how many requisitions are open, how many people apply, how many pass each round and where candidates drop off. The recruitment funnel is a tool that turns recruiting from a matter of gut feeling into numbers you can make decisions with.

6 Stages of the Recruitment Funnel to Track

The standard funnel in Thailand in 2026 has six stages, each with its own conversion rate.

Six Stages and the Numbers to Watch

1. Sourced: the number of candidates found or who applied
2. Screened: passed the first-round resume screen
3. Interviewed: first round, around 30 to 50 percent of screened
4. Final round: passed the in-depth round, 15 to 25 percent of interviewed
5. Offered: received an offer from the company, usually 50 to 70 percent of final round
6. Hired: accepted and signed the contract, around 75 to 90 percent of offered

The conversion rate at each stage is the number you use to diagnose problems. If conversion from sourced to screened is low, the JD may be the problem. If conversion from offered to hired is low, compensation or candidate experience is the problem.

Key Metrics HR Should Track

Beyond the funnel, other metrics complete the picture.

Numbers That Belong on the Dashboard

• Time to hire, from requisition to accepted offer, broken down by level and job family
• Cost per hire, including platform costs, agency fees and HR time converted to baht
• Quality of hire, measured by performance rating and first-year retention
• Source effectiveness: which platform produces the most candidates who pass
• Offer acceptance rate: for every decline, you need to know where they went
• Diversity ratio at each stage, to see whether the funnel filters through bias or opens doors

Incomplete tracking creates a distorted picture. For example, if you measure only time to hire without looking at quality, the company rushes to hire unsuitable people. The numbers look good, but you pay for it in first-year attrition.

Analysing Drop-off to Fix the System

Drop-off at each stage tells you something different.

Interpreting Drop-off

• High drop-off after applying: the JD or company isn't attractive, or the qualifying screen is fairly heavy
• High drop-off after screening: the candidate pool is low quality, so review your sourcing strategy
• High drop-off after the first interview: the questions or scoring rubric may be unclear
• High drop-off after the offer: compensation or candidate experience is the problem
• High drop-off between signing the offer and the start date: pre-start onboarding is poor

Focus first on the stage with the highest drop-off. Fix it there and measure results for 8 to 12 weeks before moving on to another stage. Trying to fix every stage at once usually ends with nothing changing.

A funnel is not a month-end report. It is a live diagnosis of the process. Those who collect data have the power to adjust; those who don't must rely on instinct.

Setting Internal and External Benchmarks

Once you have metrics, you need to know whether the numbers are good or bad. Use two layers of benchmarks.

Setting Benchmarks

1. Internal benchmark: the company's own figures for the last 12 months, broken down by role family
2. External benchmark: from HR consulting firms or industry reports
3. A quarterly trend line to see whether the direction is up or down
4. Outlier check: analyse separately any positions whose time to hire differs greatly

For example, if time to hire for a senior engineer is 75 days compared with 30 days for a junior engineer, that's normal. But if both are at 90 days, there is a process problem deeper than the role level.

Reporting to Executives

All the numbers need to be presented visually for executives. On one page, include a visual funnel, the time to hire trend, and alerts for outliers that need help.

Monthly Report Topics

• Number of requisitions opened, closed and remaining
• The overall funnel and conversion rates
• Time to hire compared with benchmark
• Quarterly cost per hire
• The top 3 positions with recruiting problems
• Action items that need support from executives

Good reporting isn't about showing off numbers. It tells a story that ends with a request for help on a specific point.

Connecting the Funnel to Your Tools

Collecting data manually in Excel doesn't scale. A good ATS tracks the funnel automatically, and AI helps analyse patterns. Read Reducing Time-to-Hire with AI to understand where AI can reduce drop-off, and Candidate Experience: Why Applicants Disappear to fix drop-off at the late stages of the funnel.

Measuring the recruitment funnel well connects back to Writing Job Descriptions That Attract Top Talent and AI candidate screening, because drop-off problems are often fixed at the top of the funnel.

In summary, the recruitment funnel is a tool that lets HR make a business case in the meeting room and decide based on data, not feelings.
