Data-Driven Hiring: What Founders Should Actually Measure

“Data-driven hiring” has become a common phrase in startups. Most founders genuinely want to make better, more objective hiring decisions, but in practice, many teams end up tracking the wrong things.

Founders do care about data, the challenge isn’t where the data comes from (it almost always comes from the ATS), but which metrics teams choose to pay attention to once the data is there.

If your goal is to make hiring faster, more consistent, and less stressful, it helps to rethink what sits on your hiring dashboard.

Here’s a more useful way to look at it.

Quality of hire, not just speed

A lot of teams naturally gravitate toward how quickly a role is filled and that’s understandable.

But the more meaningful question is: did we hire the right person?

A practical way to assess this is to look at:

  • How the person performs in their first 90 days

  • Whether their manager feels confident in the hire

  • Whether the person is still with the company after 6–12 months

A fast hire that doesn’t work out creates more disruption than value. Over time, quality of hire is the metric that really moves the needle.

Interview-to-hire ratio

Many startups don’t realise how inefficient their process is until they actually count interviews.

If you’re regularly interviewing too many people to make one hire, that usually signals something worth fixing, often around role clarity, sourcing, or interview design.

In early-stage environments, a healthier benchmark tends to be closer to 4–6 interviews per hire.

If your ratio is higher, it’s not a failure, it’s simply a helpful signal that your process could be tighter.


Candidate experience signals

Your hiring process shapes how candidates see your company, whether you intend it to or not.

Simple things worth tracking include:

  • How quickly you respond to candidates

  • Whether you give clear feedback

  • Your offer acceptance rate

If strong candidates are declining offers or disengaging mid-process, that’s useful information. It often points to opportunities to make your process clearer, faster, or more consistent.


Time to fill

Time to fill is the time from role approval to signed offer.

Time-to-fill is worth tracking because it tells you something about your process, your resourcing, and your urgency.

Long time-to-fill can signal:

  • unclear role definitions

  • weak sourcing channels

  • slow decision-making

  • or unrealistic expectations about the market

However, it shouldn’t be treated as a success metric on its own. You can reduce time-to-fill by lowering the bar, rushing interviews, or making safer (but weaker) hires. So definitely track it, but read it alongside quality of hire, not instead of it.


Time to hire

Time to hire, often confused with time to fill, is the time from when a candidate enters your pipeline to accepted offer.

Unlike time-to-fill, which is influenced by sourcing, market conditions, and role clarity, time-to-hire specifically reflects how well your interview process works once candidates are in play.

If your time-to-hire is too long, it often signals:

  • too many interview stages

  • poor scheduling (founders unavailable, slow decisions)

  • unclear decision criteria

  • misalignment between hiring manager and interviewer panel

  • repeated “restarts” of the process

So it’s a good proxy for interview efficiency and decision quality.


Number of applicants

Application volume is still worth paying attention to because it reflects how visible and compelling your role is in the market.

Low application numbers can indicate:

  • a poorly written job description

  • uncompetitive salary

  • weak employer brand

  • or misaligned role positioning

That said, high volume rarely equals high quality. Most inbound applications are noise rather than signal.

So track applications to understand your attraction engine but judge success by shortlist quality, not applicant count.


Number of CVs reviewed

It can be helpful to know how many profiles are being screened for each role because it reveals how efficient your funnel is.

If you’re reviewing hundreds of CVs per hire, that usually means:

  • your sourcing is too broad, or

  • your job criteria aren’t clear enough, or

  • your screening approach is underpowered

However, sending large numbers of CVs to hiring managers is not a sign of good recruiting. The best hiring outcomes come from careful curation, not volume. So track CV review numbers as a system diagnostic, not as a performance target.


Offer to acceptance rate

Offer acceptance rate is a core outcome metric that reflects both your hiring process and your employer proposition. It shows whether candidates ultimately chose you when given the option.

If acceptance rates are consistently low, it often points to issues such as:

  • uncompetitive compensation,

  • lack of role clarity,

  • a slow or messy process, or

  • how the company showed up during interviews.

Read alongside quality of hire, acceptance rate helps you understand whether you are not just selecting well, but also being selected in return.


NPS score

Candidate NPS gives you a measurable read on how people experienced your hiring process from their point of view. It captures both how the process felt and how well it worked in practice, including whether it was clear, respectful, efficient, and credible.

Low NPS usually isn’t caused by one single moment; it tends to reflect accumulated friction across the journey, for example unclear communication, slow decisions, too many stages, or an overall process that felt unnecessarily drawn out.

Hiring consistency

“Consistency” is the reliability of your hiring system over time.Great hiring isn’t just about one-off wins, but about consistency over time.

Useful questions to ask:

  • Can you reliably produce a shortlist every 3–5 weeks?

  • Do you generally know how long roles will take?

  • Or does each hire feel like a fresh scramble?

If hiring feels unpredictable, that’s usually a sign you need more structure, not more effort.


A note on metrics

Hiring metrics are most valuable when they are used as diagnostic tools rather than targets in their own right. No single measure can define success; what matters is how the metrics interact to reveal the health of your hiring system.

Metrics and data are valuable because they help you spot patterns, surface risks, and recognise what’s working. But in our view, it’s important not to become overly fixated on them. Recruitment is ultimately a holistic process that involves judgement, relationships, context, and nuance, not everything meaningful can be neatly quantified.

The goal isn’t to turn hiring into a dashboard; it’s to use data as a guide while still leaving room for human decision-making.
