Candidates per opening

Candidates per opening is the total number of applicants who apply for each open position. Unlike candidates per hire, which measures funnel efficiency from screening to offer, candidates per opening measures the breadth of interest in your roles before any screening takes place. It answers the question: "How many people want to work here in this role?"

A high number of candidates per opening can be a positive signal: the role is attractive, the employer brand is strong, and the job posting is reaching the right audience. However, it can also indicate that the job description is too vague, attracting unqualified applicants, or that the posting is on high-volume channels that prioritise quantity over relevance.

A low number of candidates per opening is more straightforward to interpret: the role is hard to fill. This may be because the talent pool is small (niche skills, senior roles), the compensation is below market, the employer brand is weak in the target segment, or the job posting is not reaching the right audience.

The metric is most useful when compared across role types, departments, and time periods within your own organisation. Comparing candidates per opening for your engineering roles this quarter versus last quarter is more informative than comparing your number against an industry average, because your specific market position, location, and employer brand create a unique baseline.

Divide the total applications received by the number of open positions. For role-level analysis, count all applications received for a specific requisition. For organisation-level trends, sum all applications across all openings and divide by the total number of requisitions.

Be consistent about what counts as an application. Some organisations count only completed submissions, while others include partial or abandoned applications. The former provides a cleaner measure of genuine interest; the latter captures broader market reach. Whichever definition you use, apply it consistently over time.

A metric tree breaks the applicant volume into the factors that drive it, revealing whether high or low volume is a function of market conditions, employer brand, job posting strategy, or role attractiveness.

This tree helps distinguish between controllable and external factors. If candidates per opening drops for engineering roles across all channels simultaneously, the cause is likely market-driven: increased competition, a shrinking talent pool, or a shift in candidate preferences. If the drop is limited to a specific channel or role type, the cause is more likely within your control: a weak job description, below-market compensation, or a posting that is not reaching the target audience.

The tree also helps when volume is too high. If a role receives 500 applications but only 20 pass initial screening, the problem is not volume but relevance. The job description or posting channels are attracting the wrong candidates, creating a large but low-quality pipeline that consumes significant screening effort.

1. 1

   Strengthen your employer brand in target segments

   A strong employer brand increases candidates per opening for the right roles. Invest in content that showcases your culture, team, and projects to the specific audiences you want to attract. Employees sharing their experiences on social media and review platforms amplifies this effect.

2. 2

   Optimise job descriptions for clarity and appeal

   Write job descriptions that clearly communicate the role, the team, the impact, and the benefits. Avoid jargon-heavy requirements lists that discourage qualified candidates from applying. Include salary ranges where possible, as postings with compensation information attract significantly more applicants.

3. 3

   Diversify sourcing channels strategically

   Track candidates per opening by channel and invest in those that produce the right volume and quality. Niche job boards, professional communities, and referral programmes often produce better-matched candidates than broad-reach platforms.

4. 4

   Build talent communities for recurring role types

   For roles you hire repeatedly, build a community of interested candidates through events, content, and ongoing engagement. When a position opens, you have a warm audience to reach immediately, reducing time to fill and increasing the quality of the applicant pool.

5. 5

   Review and adjust posting frequency and timing

   Job postings lose visibility on most platforms after the first few days. Refresh postings, adjust titles, or repost at optimal times to maintain visibility throughout the hiring period. Test different posting days and times to find what produces the best response.

KPI Tree lets you model candidates per opening alongside qualified candidate ratios, source channel performance, and employer brand metrics. This creates a complete view of the top of your hiring funnel: not just how many people apply, but where they come from, how well they match, and what drives the volume up or down.

The tree can be segmented by role type, department, location, and channel to identify patterns. When candidates per opening drops for a specific segment, the tree shows whether the decline is due to market conditions, posting strategy, or compensation gap, guiding the appropriate response and potentially affecting cost per hire.

Connecting this metric to downstream funnel metrics like candidates per hire, time to hire, and quality of hire ensures that optimising volume does not come at the expense of quality. The goal is a sustainable pipeline of well-matched candidates, not maximum application volume.
