Recruiters often measure effort - like the number of resumes screened or emails sent - but these don’t guarantee hiring success. To improve outcomes, focus on metrics that track results, not just activity. Key metrics include:
- Response Rate: Measures how many candidates reply to outreach. Aim for 30%+ for developer roles. Personalize messages with salary and tech stack details to improve developer response rates.
- Time-to-Fill: Tracks how quickly roles are filled. Developer roles take ~42 days; faster processes help secure top talent.
- Candidate Engagement: Monitors meaningful interactions, like interview scheduling. High engagement shows genuine interest but requires valuing candidates' time.
- Offer Acceptance Rate (OAR): Reflects how many offers are accepted. Healthy OAR is 80–90%; shorten the gap between interviews and offers to improve this.
- Quality of Hire (QoH): Evaluates long-term success through retention and performance.
Core Metrics That Predict Hiring Success
If you want to predict hiring success, focus on metrics that track outcomes instead of just measuring effort. Think about things like what developers want, how quickly roles are filled, and how engaged candidates remain throughout the process.
Response Rate: Measuring Candidate Engagement
The response rate is calculated by dividing the number of replies by the total outreach messages sent, then multiplying by 100. For example, if you get 35 replies out of 100 messages, your response rate is 35%. For developer roles, anything above 30% is considered strong.
Why is this important? Developers are quick to spot generic outreach. In fact, 64% of developers think recruiter messages are just copy-pasted templates . Without trust in your message, developers are unlikely to reply.
To improve your outreach, include key details like salary and tech stack upfront. Research shows that 69% of developers want salary information in the first message, and 71% want to know the tech stack and role scope right away . On the flip side, 19% will ignore your message if salary details are missing .
Once you’ve nailed your outreach, it’s time to look at how efficiently your hiring process moves candidates forward.
Time-to-Fill: Reducing Hiring Cycle Length
Time-to-fill measures how many days pass between posting a job and getting an accepted offer. For developer roles, this timeline can vary based on seniority. For instance, data scientist roles take about 60 days on average, while other technical roles fill in around 42 days. By comparison, many business roles fill in closer to 32 days .
A shorter hiring cycle is crucial because in-demand tech talent typically stays available for only 10 days. If your process is slow, you risk losing top candidates to faster-moving competitors. Thanos Markousis, VP Operations at Workable, highlights the need for proactive hiring to keep pace with company growth .
Open roles can cost 1.5–3 times the employee's annual salary in lost productivity. For example, in 2025, Frasers Group cut its time-to-hire for retail roles from 23 days to just 9 days by streamlining interviews and ensuring hiring managers responded faster . You can adopt similar strategies by setting 24-hour feedback deadlines after interviews, using standardized scorecards for quicker decisions, and leveraging tools like daily.dev Recruiter to connect with pre-qualified candidates and skip the cold outreach phase.
Candidate Engagement Levels: Tracking Interaction Quality
Beyond response rates and hiring speed, another key metric is how engaged candidates are throughout the process. Candidate engagement tracks meaningful actions like replying to messages, scheduling interviews, completing assessments, or asking questions about the role. It’s useful to monitor how candidates move through the pipeline - from initial contact to phone screens and technical interviews.
High engagement often signals genuine interest. However, 67% of developers rate recruiter respect for their time as a 0–2 out of 5 . Spammy messages and irrelevant roles are common complaints. When developers feel their time isn’t valued, engagement drops - and so do your chances of hiring them.
To keep candidates engaged, respect their time. Avoid lengthy application forms and make next steps clear. Tools like daily.dev Recruiter help you connect with developers who are already active in the community. When candidates trust that you understand their needs, they’re more likely to stay engaged, boosting your hiring success in the process.

Additional Metrics for Better Hiring Predictions
In addition to tracking initial engagement, incorporating these metrics can help ensure both short-term and long-term hiring success.
Offer Acceptance Rate: Predicting Final Hire Success
While engagement and hiring speed are essential, tracking tech recruitment metrics adds another layer to refining your strategy.
Offer acceptance rate (OAR) is calculated by dividing the number of accepted offers by the total number extended, then multiplying by 100. For example, if you make 10 offers and 8 are accepted, your OAR is 80%. For developer roles, a healthy range typically falls between 80% and 90%.
From 2021 to 2024, the average OAR was 78% . In 2023, it climbed to 81% , and by early 2025, it reached 84% . However, technical roles lag behind, averaging 73%, compared to 84% for business roles .
Timing is critical here. Candidates who accept offers usually do so within 2 days, while declines take closer to 6 days . Shortening the gap between the final interview and formal offer can capture candidate enthusiasm and improve acceptance rates.
Tools like daily.dev Recruiter can help by connecting you with candidates already active in the developer community. High-context job descriptions that highlight technical challenges and team dynamics resonate better than generic postings, increasing the likelihood of offer acceptance.
While OAR reflects immediate hiring success, long-term success is tied to quality of hire metrics.
Quality of Hire: Measuring Long-Term Performance
Beyond initial metrics, quality of hire (QoH) gauges the long-term impact of your hiring decisions.
QoH evaluates new hires based on performance and retention. Key indicators include first-year retention rates, time-to-productivity (how quickly a new hire starts making meaningful contributions), and hiring manager satisfaction scores.
This is no small matter: 20% of employees leave within their first 45 days , and top performers can deliver up to four times the output of average employees . Hiring developers who ramp up quickly and stay engaged can significantly boost team effectiveness.
With daily.dev Recruiter, you gain access to pre-screened candidates through a double opt-in model. These developers are already active in the community and have shown interest in new opportunities, making them more likely to align with your technical needs and workplace culture. This upfront filtering reduces mismatches and helps improve retention over the long term.
