TL;DR

Candidate Net Promoter Score (cNPS) measures how likely candidates are to recommend your hiring process to others, on a scale of 0 to 10. It is calculated by subtracting the percentage of detractors (0-6) from the percentage of promoters (9-10). It is one of the few metrics that captures candidate experience across the full recruitment funnel, including people you rejected.

How cNPS Is Calculated and What the Numbers Mean

cNPS borrows its methodology directly from Net Promoter Score, the customer loyalty metric developed by Fred Reichheld at Bain. Candidates are asked: "How likely are you to recommend our hiring process to a friend or colleague?" Scores 9-10 are promoters. Scores 7-8 are passives (counted but not included in the calculation). Scores 0-6 are detractors. The formula: cNPS = percent Promoters minus percent Detractors.

Scores range from -100 to +100. A score above 0 means you have more promoters than detractors. A score above 50 is considered strong. A score above 70 is exceptional. Most organizations that measure cNPS land between 20 and 45; scores below 0 indicate a systemic problem with the candidate experience.

The survey should be sent at multiple points in the funnel: after application submission, after each interview stage, and after the hiring decision (including rejections). Candidates who were rejected but had a positive experience are a recruiting asset. They tell friends. They reapply for future roles. They may buy your client's products. Candidates who were rejected and had a poor experience do the opposite, and they are not quiet about it. Glassdoor has made candidate experience public; cNPS gives you quantified visibility into it before it becomes a review.

Why It Matters for Recruitment

Candidate experience has a direct dollar value that most agencies do not quantify. Virgin Media calculated in 2014 that rejected candidates who became brand detractors cost the company $5.4 million per year in lost subscriptions. Staffing agencies face a version of this: candidates who have poor experiences with an agency stop accepting calls, stop referring friends, and actively warn peers. In a tight labor market, that reputation damage narrows the candidate pool in ways that do not show up on any sourcing dashboard.

For agencies pitching MSP or RPO contracts, cNPS data is a differentiator. Most agencies make qualitative claims about candidate experience. An agency that presents benchmark cNPS data, trend lines, and process improvement initiatives tied to specific score drops is making a quantified argument. Procurement teams and HR leadership notice.

cNPS also acts as an early warning system. A drop in post-interview cNPS at a specific client site often precedes an uptick in offer declines or early attrition. The score catches the problem in week 3; the offer decline data shows it in week 8. Earlier signal means earlier intervention.

In Practice

A specialist technology staffing agency sends cNPS surveys at three funnel stages across all active searches. Quarterly review reveals that post-first-interview cNPS for one key client is 31, while the agency average is 58. Exit comments cluster around "interview ran 90 minutes over schedule" and "no feedback provided after the interview." The agency works with the client to implement a 60-minute interview cap and a structured 48-hour feedback loop for all candidates. Over the following quarter, post-interview cNPS for that client rises to 52. Offer acceptance rates improve from 71 to 84 percent, generating an estimated four additional placements per quarter at the client's average fee of $18,000.
