NPS In Recruitment: When Rejected Candidates Stop Being Customers (Part 1)

Petra Nůličková, an experienced HR leader with over 15 years in talent acquisition and employer branding, shows in this two-part series why NPS (Net Promoter Score) isn’t just another metric but a strategic tool that can transform your recruitment from a cost centre into a competitive advantage.

In this first part, you’ll discover:

1. What is NPS, and why does it matter specifically in recruitment?
2. Why candidate experience is critically important (especially in e-commerce where candidates are also your customers).
3. You will learn how to successfully implement and interpret NPS in your recruitment process.

We’ll explore the connection between candidate experience and business results and show you how to identify red flags in your data that reveal where your process is failing.

Part 2 will follow soon, where we’ll focus on practical action—how to turn dissatisfied candidates into advocates, implement changes based on feedback, measure tangible results, and learn from real e-commerce case studies. Because in e-commerce, where the boundary between candidate and customer disappears, candidate experience directly impacts your bottom line.

Introduction To NPS In The Recruitment Process

What Is NPS And Why Is It Important Specifically In Recruitment

NPS (Net Promoter Score) is a simple but highly revealing indicator of how satisfied people are and how inclined they are to recommend you further.

In recruitment, we ask a single question: “How likely are you to recommend our selection process to your acquaintances?”

The candidate responds on a scale of 0–10. This immediately shows us how many people leave enthusiastic (9–10), how many are neutral (7–8), and how many are genuinely dissatisfied (0–6).

And why is this so important specifically in recruitment? Because for the candidate, the selection process is the first and often only contact with the company. If the company fails here, it fails in the candidate’s eyes as a whole. NPS gives us a very clear signal of what works, what’s problematic, and where people lose trust, patience, or a sense of fairness. Without this data, we’re just guessing. With it, we know and can plan action steps.

The Connection Between Candidate Experience And Overall Company Success

What a candidate experiences during recruitment leaves a lasting impression. It influences the company’s reputation, referrals, candidates’ future willingness to apply again, and sometimes even business results.

A satisfied candidate will recommend you further, return later, and follow your future opportunities.

A dissatisfied candidate will do exactly the opposite — often very publicly.

And in e-commerce or retail, this applies doubly: candidate = potential customer. If you disappoint a candidate in recruitment, you sometimes lose a customer too.

Candidate experience, therefore, isn’t just an HR discipline. It’s part of the company’s business strategy. And it’s a metric that should fundamentally matter to me as an HR leader.

Current State Of NPS Usage In HR Vs. In Marketing/Sales

Whilst marketing has been using NPS as a standard for years, HR is only just beginning to catch up. And this despite us discussing it for many years, significantly from around 2018, when NPS was a topic discussed at many conferences. Which is paradoxical – HR works with people at key moments when first impressions, trust, and relationships with the company are formed. The recruiter is often the first person a candidate meets and can significantly change their opinion of the company.

Marketing invests large amounts to ensure customers have a positive experience. HR invests in career pages, recruitment systems, HR campaigns, and so forth. HR often works with an equally fundamental experience – just instead of a customer, it’s a candidate – and often all that’s needed for a good experience is:

• quick response,
• human communication,
• keeping promised deadlines,
• clear information.

If HR doesn’t measure NPS, it’s missing out on an enormous amount of data.

If it does measure it, it gains a tool that allows recruitment to be improved systematically, not just intuitively. You can often discover things that wouldn’t have occurred to you. For example, that rejecting a candidate the same day unfortunately doesn’t evoke positive emotions in them, or that excessive feedback when you’ve only briefly spoken with a candidate isn’t taken very positively by them.

Why Candidate Experience Is Critically Important

The Impact Of First Impressions On Employer Brand Perception

A candidate’s first contact with the company often happens precisely in recruitment. And whilst for HR it’s a “routine process,” for the candidate it’s a unique and often stressful moment. In Czechia, people don’t regularly change jobs, i.e., it’s not common for them to go through selection processes every two years; it’s truly a fundamental decision accompanied by concerns. The way we treat them in these first minutes and days influences:

• whether they connect emotionally with the company,
• whether they’ll trust our decision-making,
• and whether they’ll speak about us as a great company… or as a company that disappointed them.

First impressions can’t be taken back. We may not influence whether we get the best candidate, but we certainly influence how they speak about us afterwards. And even people we reject can become our advocates.

Candidates As Potential Customers (Especially In E-commerce)

In e-commerce and retail, the boundary between candidate and customer practically disappears. The person who sends their CV today is often the same person who shops with you several times a year, follows your campaigns, or has your products at home. And that means one thing — candidate experience has a direct impact on how they’ll behave as a customer too.

A negative experience in recruitment doesn’t stay just in recruitment. It damages reputation, reduces loyalty, and can cause the candidate to decide they simply don’t want to shop with you anymore. Sometimes consciously, other times subconsciously. It’s the same psychological mechanism as with poor customer experience — only much more personal because it touches the person directly.

In e-commerce, therefore, we can’t afford to view the candidate separately from the customer. In reality, it’s one and the same person—and we should treat them accordingly. Fast response, fairness, and simple humanity often have a greater impact than any marketing investment.

The Connection Between Candidate Experience Quality And The Quality Of Hired Employees

Candidate experience isn’t just about feelings. It has a direct impact on whom we ultimately hire and how long they stay with us. When a candidate experiences fair treatment, a quick response, and human communication during the selection process, they arrive at the company with completely different energy. They’re more motivated, have higher trust in the company and team, and usually engage in work more quickly. For them, recruitment is confirmation that the company is worthwhile — and that’s how they approach it.

Conversely, a negative experience can deter even a very qualified candidate before they reach the first round. The candidate often tells themselves that if the company doesn’t function well in recruitment, it won’t function well inside either. And that’s the moment when we lose them — not due to incompetence, but due to poor experience.

The better the candidate experience, the greater the chance we’ll attract the right people and that those people will stay longer. A positive experience reduces onboarding costs, accelerates adaptation, and supports long-term retention. A candidate who experienced fairness and respect from the start has a far greater tendency to behave the same way towards the company.

Candidate experience, therefore, isn’t just “something extra.” It’s a key element of recruitment quality — and the first step towards building a truly strong team.

Implementation Of NPS In The Recruitment Process

Key Moments For Measuring Candidates’ NPS (After Interview, After Onboarding)

The ideal time for measuring NPS is always when something concludes. When the candidate completes a certain phase and has enough information to realistically evaluate it.

Typical moments:

• rejection after CV,
• rejection after pre-screening,
• rejection after task,
• rejection after interview,
• or conversely after offer (accepted vs. didn’t accept),
• after case study,
• after first meeting with manager,
• after final round.

The candidate gets the opportunity to evaluate each part separately — and thanks to this, you know exactly where recruitment “leaks.”

Proposal For Effective Questions Beyond Standard NPS Score

• Were you satisfied with the speed of our response? Speed is the most common reason for low NPS.
• Was the information about the selection process sufficient and clear? Lack of clarity kills trust.
• How would you rate the professionalism of HR and the manager? Excellent for revealing weak links in the process.
• Did you receive relevant feedback? Feedback significantly influences the candidate’s impression.
• Did you understand the requirements and content of the position? This question reveals whether you have a well-written advertisement.

Technological Tools For Automating Feedback Collection And Evaluation

ATS systems often allow questionnaires to be sent automatically. If you don’t have them, you can use Google Forms, Typeform, or a connection to Power BI for data analysis. You can, of course, use any automation through AI, which will save you time.

Interpretation Of NPS Data

When a company starts measuring NPS, there’s usually initial enthusiasm:

“We have numbers!” But the truly fundamental moment comes afterwards — at the point when the team opens the results and must ask themselves, “What does this actually tell us? And what do we do with it?”

And this is precisely where NPS often breaks down. Correct interpretation isn’t about the number itself, but about how deeply we can look into the data and whether we have the courage to see reality without embellishment.

How To Correctly Read And Segment Obtained Scores

One single number for all recruitment actually tells you almost nothing. It can be beautiful, it can be catastrophic — but without context, you won’t understand why. NPS only makes sense when you divide it into smaller parts and start tracking candidate behaviour patterns.

Track trends over time, not one-off fluctuations. NPS isn’t a KPI for one campaign. It’s a long-term metric. You’re interested in questions:

• Have we been improving over the last 3–4 months?
• Are we declining after a certain change in the process?
• Were there any events that could have influenced candidates’ mood (team change, reorganisation, prolonged “silence”)?
• Which positions have high NPS and which have low?
• What keeps repeating in open-ended questions?

You might be surprised that NPS is often the toughest metric of recruiter quality. It doesn’t evaluate performance but the actual candidate experience — what the recruiter leaves behind.

If you see differences between individual recruiters or teams:

• they have different communication styles,
• someone is faster, someone less so,
• someone knows how to give quality feedback, someone avoids feedback.

This data is a gold mine for HR team development. One-off numbers can be misleading; track trends. And combine data with comments in the questionnaire – the number gives context, and the comment shows and explains why.

Identification Of “Red Flags” In The Recruitment Process

One of NPS’s greatest values is that it can very quickly show where recruitment is truly problematic. Not through assumptions or intuition, but through candidates’ real experience. And when you dive deeper into the data, recurring signals begin to appear – those “red flags” that no HR team should ignore.

The first of these is a sharp drop in NPS immediately after first contact with the company. This usually means the candidate waited a long time for a response, received an impersonal template, or the communication wasn’t clear about what actually awaits them. First contact has enormous weight — the candidate uses it to estimate how the company will treat them going forward. If they already feel overlooked at this stage, it’s very difficult to win them back.

Another big flag is dissatisfaction after tasks and tests. This most commonly shows a lack of respect for the candidate’s time. Assignments are sometimes too long, unclear, or don’t make sense given the position. And if no response comes after submission, it’s a frustrating experience for most people that appears very often in comments. The candidate then speaks about feeling their work was pointless — and that’s something that brings candidate experience down fastest.

The part where the candidate meets the manager is also very sensitive. If NPS drops significantly after this round, it usually means a problem directly in the interview. The manager may appear unprepared, casual, or even arrogant. At such a moment, the candidate doesn’t just take away a bad feeling about the person — they take away a bad feeling about the company as a whole. And that’s precisely the information you won’t discover without NPS.

A drop in satisfaction after an offer is a special chapter. Although it may seem paradoxical, it’s a common phenomenon. It indicates a mismatch between what the company presented during recruitment and what it’s ultimately willing to offer. This typically concerns salary, benefits, or work structure. The candidate then speaks about unmet expectations — and trust evaporates within a minute.

One of the most significant signals comes when you compare NPS after recruitment and NPS after onboarding. If the difference is large, it’s a strong indicator that recruitment wasn’t sufficiently transparent. The candidate experienced the selection process as pleasant, but the reality of the team, work, or leadership doesn’t match it. In such a case, the problem isn’t so much in HR but rather in the overall consistency of the company.

And finally, there’s a red flag that goes beyond recruitment and touches on culture: comments about loss of direction, chaotic communication, or uncertainty within the company. These signals are very valuable for HR because they show that candidate dissatisfaction isn’t caused by recruitment itself but by the atmosphere inside. And here it’s necessary to involve leadership — the data touches on much deeper topics than response speed.

When you catch these signals in time, you can not only make recruitment more efficient but above all increase candidates’ trust and strengthen the company’s reputation. And that’s precisely the moment when NPS becomes a real tool for change from a mere metric.

From Data To Action: How To Use NPS To Improve Recruitment

Measuring NPS is simple. The hardest part comes at the moment when the HR team looks at the results and must ask the question:

What follows from this and what do we do with it now? This is where it becomes clear whether NPS truly moves recruitment forward or remains just a table we look at once a quarter and that’s the end of it.

The first rule is clear: data alone changes nothing. Change only comes from reacting to it.

Ways To Transform Detractors Into Promoters

It may sound paradoxical, but dissatisfied candidates are often the most valuable group. Their feedback tends to be specific and honest — and if we work with it well, it can simultaneously be the path to turning even a negative experience ultimately positive.

A detractor doesn’t become a detractor because they want to harm the company. They become one because they had certain expectations — and those weren’t met. It’s usually nothing major. Often simple human steps that restore respect and fairness to the relationship are enough.

For example:

• The candidate waited too long for a response. It’s enough to contact them, admit the delay, apologise, and explain what happened. The candidate will appreciate that you didn’t sweep the situation under the carpet.
• Feedback didn’t arrive after a task or test. If you contact them additionally, thank them for their time, and give them two or three specific things that went well and what they could improve next time, you have a great chance of significantly changing their impression.
• The candidate wasn’t suitable for the given position but is interesting for the company. Here, offering another more suitable role can work wonders. Or at least a recommendation of where they might fit — even outside your company. It’s a small gesture that seems unexpectedly human.
• The candidate felt misunderstood during the interview. A brief follow-up in which you explain the decision and give space for additional questions can transform frustration into respect.

When a company responds quickly, politely, and openly, candidates often say themselves that this approach surprised them. And that thanks to it, they’re taking away a much better feeling than they expected. It’s not about fixing a “mistake.” It’s about the candidate seeing that you care about them.

Implementation Of Changes Based On Qualitative Feedback

Qualitative feedback shows where exactly the process fails. It’s not enough to look at one number — it’s important to track trends and look at data by individual phases, recruiters, and types of positions. Only then will you discover where the greatest friction arises.

Often, moreover, it’s not about big changes but about small details that candidates notice immediately. For example:

• Shortening response time. If candidates repeatedly write that they waited a long time, you only change two things: clearly say when you’ll be in touch and keep that deadline. Or let them know that the process will be prolonged. Speed is the most common reason for low NPS — and simultaneously the easiest to fix.
• Correction of automatic email templates. Technically automatic, emotionally human. A few extra sentences, specific information about steps, and a tone that doesn’t seem like a robot are enough. The candidate notices the difference immediately.
• Preparation of hiring managers. If NPS drops after an interview, the problem isn’t in HR but in manager preparation. A simple briefing helps: what to say, what’s better not to say, how to present the role, and how to conduct a structured interview.
• Improvement of position descriptions. When candidates write in comments that they didn’t understand the role or it was different from what they expected, it’s a signal to adjust the advertisement. Clear expectations = less frustration and fewer unsuitable applications.
• Additional communication during the selection process. Silence is the biggest killer of candidate experience. A brief clarification like “we’re waiting for feedback,” “the process will be prolonged,” or “we’ll be in touch by Wednesday” raises NPS by tens of points.

Small adjustments that take a few minutes often have a greater impact than any major process change. Candidates agree on them most often in comments — and that’s precisely why they’re ideal quick wins to start with.

Creating A Closed Feedback Loop For Continuous Improvement

NPS only makes sense when it becomes a regular cycle, not a one-off exercise. It’s not enough to evaluate data once — you need to work with it over and over again. Simple principle:

data → analysis → changes → implementation → further measurement → new feedback.

It’s precisely this repetition that separates companies that improve candidate experience from those that just collect numbers in tables. Candidates notice the difference very quickly — they recognise that what they wrote in the questionnaire had an impact. And that’s the moment when trust in the process and in the HR team begins to grow.

The key is to truly maintain two things: regularity (measure even outside “crisis periods”) and courage to act based on data. Without both, NPS becomes just a metric. With them, it’s conversely a tool that gradually and stably moves the entire recruitment process forward.
