Recruitment Reports: How to Make Data-Driven Decisions, Not Gut Feelings

The problem: recruitment based on gut feeling and spreadsheets

Ask any HR director "How long does it take on average to hire a developer?" and you'll get vague answers: "about a month", "it depends", "it varies case by case". Ask "Which recruitment channel brings the best candidates?" and you'll get an even less clear response: "LinkedIn in general, but I'm not sure." This lack of clarity isn't a competence problem — it's a tools problem.

Most HR teams still make recruitment decisions based on intuition, personal experience, and at best, sporadically updated manual spreadsheets. A McKinsey study shows that organisations that use analytics in the recruitment process are 3x more likely to improve hiring quality and 2x more likely to reduce costs. The difference doesn't lie in having more data — but in having data that is structured, visualised, and actionable.

Treegarden transforms every action in the recruitment process into a data point. Every application received, every move in the pipeline, every scheduled interview, every offer sent, and every completed hire is recorded automatically. This data feeds a suite of reports that provide a clear, objective, and real-time picture of the entire recruitment process.

Pipeline Overview: where your candidates are right now

The Pipeline Overview report is the starting point for any analysis. It provides an instant snapshot of the current state of all active recruitment processes.

The report can be filtered on multiple dimensions: by specific job, by department, by responsible recruiter, or by time period. Want to compare IT department recruitment performance vs Sales last quarter? Two clicks and you have the answer.

The most valuable aspect of Pipeline Overview is identifying bottlenecks — the points in the pipeline where candidates get stuck. If 50 candidates enter the "Screening" stage but only 3 move to "Interview", you have a clear bottleneck. The cause may be: screening is too slow (the recruiter doesn't have time to evaluate all candidates), filtering criteria are too strict (AI Match Score threshold too high), or a job description that attracts unsuitable candidates. Without data, these problems remain invisible for months.

Time-to-Hire: how long hiring really takes

Time-to-hire is the queen metric of recruitment — the number of days from job posting to offer acceptance. The global average is 44 days, but varies enormously depending on industry, role, and location. For IT positions, the average time-to-hire is 35–50 days, and for administrative positions 15–25 days.

The Time-to-Hire report in Treegarden doesn't just offer a general average. It breaks down the duration at each stage of the pipeline, showing exactly where the most time is lost:

• Days in Applied — how long until a CV is reviewed after receipt. The ideal is under 48 hours.
• Days in Screening — how long the initial evaluation takes. With AI Match Score, this stage should be nearly instantaneous.
• Days in Interview — from the first scheduling to the last interview. Delays here are often caused by limited hiring manager availability.
• Days in Offer — from the final decision to sending the offer. Should be under 24 hours with AI Offer Letter Generator.
• Days in candidate decision — how long the candidate waits to respond. Dependent on external factors, but influenced by offer quality and process experience.

The trend over time is just as important as the absolute value. If time-to-hire has increased from 25 days to 40 days over the last 3 months, you need to investigate what has changed: have volumes increased? Has the team changed? Have requirements changed?

Offer acceptance rate and rejection analysis

Every rejected offer represents weeks of lost work and a significant cost — estimated at £1,500–£3,800 per rejected offer when you calculate recruiter time, interviewer time, and opportunity cost. The Offer Acceptance Rate report in Treegarden shows you not just the acceptance percentage, but also the reasons for rejections.

Treegarden allows recording the reason for rejection at every declined offer. Standard categories include: insufficient salary, better offer from another company, decision to stay with current employer, unsuitable location/schedule, too much waiting time in the process. This data, aggregated over time periods, reveals actionable trends:

• If 40% of rejections are due to salary, you have a salary competitiveness issue that needs to be discussed with management.
• If 30% of candidates choose other companies, you need to investigate what competitors are offering and how you can differentiate your offer.
• If the main reason is "too much waiting time", you have a process problem that can be solved with automation.

Advanced reports: conversions, aging, and rejection analytics

Beyond the basic reports, Treegarden offers advanced analyses that reveal nuances that simple metrics cannot capture:

Stage Conversion Rates. This report shows the percentage of candidates who move from one pipeline stage to another. The ideal conversion shape looks like a uniform funnel: out of 100 applicants, 30 move to screening, 10 to interview, 3 receive an offer, 2 are hired. When the funnel has a sudden "neck" (for example, from 30 candidates in screening, only 2 reach the interview), you've identified exactly where the process has problems.

Requisition Aging. This report lists all open positions, ordered by the number of days they've been active. Positions that exceed a certain threshold (e.g., 45 days) are highlighted automatically. Requisition aging helps you prioritise: a role open for 60 days needs immediate attention — either adjust the criteria, intensify sourcing, or escalate to management.

Job Approval Reports. In companies with formal approval processes, this report tracks how long each request to open a position takes to be approved. If a hiring manager waits 10 days for a request approval, those 10 days add to the total time-to-hire. The report identifies approvers who cause delays and provides objective data to discuss process improvement.

Rejection Analytics. Analysis of candidate rejection reasons at each stage. Why are candidates rejected in screening? Why do they fail at interview? If 60% of interview rejections are for "lack of technical skills", it means the initial screening is not rigorous enough. If the main reason is "cultural misfit", interview questions need to be adjusted.

How to use reports: from data to concrete actions

Data without action is just numbers on a screen. Here is a practical framework for transforming Treegarden reports into real improvements in the recruitment process:

Weekly pipeline review. Every Monday morning, open Pipeline Overview and check: are there candidates stuck in a stage for more than 5 days? Are there jobs with no applications in the last week? Are there new bottlenecks? This 15-minute review prevents problems before they become urgent.

Monthly KPI analysis. Once a month, generate the complete report: time-to-hire, offer acceptance rate, stage conversions, recruiter performance. Compare with the previous month and with set targets. Identify 2–3 improvement actions for next month.

Quarterly strategic review. Once every 3 months, present management with a complete recruitment analysis: trends, costs, quality, comparison with industry benchmarks. Use the data to argue for investments: more recruiters, additional tools, salary adjustments, or process improvements.

Immediate actions based on data:

1. Time-to-hire has increased by 20%? — Check the stage-by-stage report and identify where additional time is being lost.
2. Acceptance rate has fallen below 70%? — Analyse rejection reasons and adjust offers or the process.
3. A recruitment channel has conversion below 2%? — Reduce budget on that channel and redirect resources.
4. A recruiter has double the time-to-hire of the team average? — Have an individual discussion and identify blockers.

Treegarden reports vs other ATS platforms: what you get without extra costs

The ATS market has a common and frustratingly small practice: reporting features are often locked in premium plans or sold as expensive add-ons. Here's how Treegarden compares:

JazzHR includes basic reports in the standard plan, but advanced reports (source analytics, recruiter performance, custom reports) require the "Pro Plus" plan that costs an additional $59/month. Time-to-hire breakdown by stage is not available at all in the basic plan.

Greenhouse offers predefined reports that cannot be customised. Want a report that combines source data with conversion rates by department? You need to manually export the data and process it in Excel. Custom reports are only available with API access in the Enterprise plan.

Workable offers a decent visual dashboard, but PDF export with formatted charts requires the "Business" plan (from $189/month). The standard plan limits reports to the last 30 days of data.

Treegarden includes all the reports described in this article — Pipeline Overview, Time-to-Hire, Offer Acceptance, Recruiter Scorecard, Stage Conversions, Requisition Aging, Job Approval, and Rejection Analytics — in every plan, with no time or feature limitations. CSV and PDF export is included. Reports are available from day one of use, with no additional configuration.

How to transition to data-driven recruitment

The transition from intuition-based decisions to data-based decisions doesn't happen overnight. It's a gradual process that starts with simple steps:

1. Establish 3–5 key metrics you want to track. We recommend: time-to-hire, offer acceptance rate, candidates per source, and screening-to-interview conversion.
2. Set initial targets based on current performance. If time-to-hire is currently 40 days, set a target of 35 days for the next quarter — ambitious but realistic.
3. Integrate reports into your routine. Weekly review (15 minutes), monthly analysis (1 hour), quarterly presentation (2 hours). The more familiar the data becomes, the more informed the decisions.
4. Act on the data. Don't generate reports that nobody reads. Every report should lead to at least one concrete action.
5. Iterate and improve. After 3 months, evaluate whether the chosen metrics are relevant, adjust targets, and add new dimensions of analysis.

Data-driven recruitment doesn't eliminate the experience and intuition of the HR team. It complements them with objective evidence that makes arguments stronger, decisions faster, and results better. With Treegarden, the data is already there — you just need to read it and act on it.
