With the speed at which the jobs marker evolves, recruiters often feel pressured to fill roles quickly. pressure building to attract more top talent quickly and cost-effectively, many employers overlook valuable recruitment channels, including internal talent pools, referrals, and social reach. By tapping into these underused sources of talent, employers can benefit from faster, high-quality hires while saving time and resources.
This article explores how underused recruitment channels can enhance talent acquisition strategies, contributing to cost-effective recruitment processes without sacrificing quality.
The hidden cost of overlooking existing talent
Candidate sourcing is a time-intensive task, taking recruiters an average of 3.6 hours per vacancy, according to our recent research. Yet with the right strategy, sourcing can become far more efficient and cost-effective.
Often, hiring teams default to external sourcing, neglecting internal talent databases and employee networks. This not only wastes time and budget, and overlooks quality candidates already familiar with the organisation or endorsed by existing employees.
Tapping into existing internal networks can result in:
- Improved
- Quality of hire
- Lower recruitment costs
- Faster time-to-hire
Our research also shows that recruiters typically manager four open roles at a time, each receiving around 20 applications. Despite this volume, only half of those applicants move forward, and 72% of recruiters say that time spend screening unqualified candidates significantly slows down hiring.
The inefficiency has knock-on effects, with 28% of candidates dropping out of the hiring process entirely. Among them, 28% report accepting another offer in the meantime, while 25% cite lengthy delays as the reason for disengaging.
In a climate of tighter hiring budgets and increasing to do more with less, continuing to rely on external sourcing is no longer sustainable. Employers without a well-defined process for engaging internal and referred talent risks higher costs, slower hires, and losing top candidates to faster-moving competitors.
The impact on morale and retention
Overlooking internal candidates can also damage employee morale and results in higher turnover. Talented employees who see limited growth opportunities internally may seek roles elsewhere, increasing turnover costs.
By contrast, cost-effective recruitment strategies that prioritise internal mobility and referrals can reduce turnover, shorten onboarding times, and improve overall workforce engagement.
Internal talent pools: Unlocking mobility and retention
Internal mobility, the practice of moving employees across teams, departments, or roles, is a powerful strategy for driving cost-effective recruitment. It enables hiring managers to fill vacancies faster with candidates who already understand day-to-day organisational processes, reduces onboarding time while increasing retention.
Why internal mobility matters:
- Faster onboarding: Internal hires are more likely to hit the ground running as they’re already familiar with the culture, systems, and processes.
- Higher retention: Employees promoted or moved internally are more likely to stay with the organisation in the long-term, reducing costly turnover.
- Improved morale: Offering career growth opportunities boosts engagement and job satisfaction across the workforce.
How to leverage internal talent pools effectively:
- Build a live internal talent map: Maintain an up-to-date database of employee skills, experiences, and future career aspirations. This helps identify potential candidates for upcoming roles proactively.
- Promote internal vacancies: Use your career page and internal communication channels to advertise opening clearly and regularly. Make it easy for employees to discover and apply for these roles.
- Collaborate with learning and development: Align training initiatives with future organisational needs to prepare employees for new opportunities, creating a pipeline of ready internal candidates.
It’s worth noting careers pages and direct applications are among the most effective recruitment channels, with 71% of recruiters citing their importance. A well-maintained internal talent pool complements this by ensuring you maximise the value of existing employees before looking externally.
Employee referrals: Your most trusted channel
Employee referral programmes consistently deliver some of the best recruitment outcomes, often outperforming external channels in quality, retention, and cultural fit. This makes referrals a cornerstone of any cost-effective recruitment strategy.
Why referrals work:
- Better cultural fit: Employees tend to refer candidates from their networks who align well with organisational values and culture.
- Higher retention: Referral hires stay longer, reducing rehiring and training costs.
- Faster hiring: Referral candidates typically move through the hiring process more quickly that those who come from other sources.
How to activate and optimise your referral programme
- Simplify the referral process: Use intuitive platforms or software to make submitting referrals quick and easy and remove barriers that discourage participation.
- Offer meaningful rewards: Monetary incentives are a great way of motivating employees to refer candidates. If budget is an issue, recognition, and non-monetary perks can also be effective.
- Provide clear job context: When sharing openings, include detailed role descriptions and ideal candidate profiles so employees can make informed referrals.
- Spotlight success stories: Publicly recognise employees who refer successful hires to encourage ongoing participation.
- Maintain confidentiality: Respect privacy by keeping referral statuses confidential, which builds trust in the process.
Additionally, referrals often foster cross-team collaboration, as employees engage with colleagues to identify strong candidates. This secondary benefits strengthens organisational culture while supporting cost-effective recruitment.
We found that 68% of large businesses and 52% of SMEs rate employee referrals as highly effective recruitment channels, underscoring their critical role in reducing hiring cost and improving outcomes.
Social media: Empowering employee advocacy
Social media has become an indispensable tool in recruitment, but employee-led sharing far outperforms traditional employer branding efforts. By empowering your workforce to act as brand ambassadors, you can dramatically increase your reach and attract diverse, high-quality candidates at minimal cost.
Why employee advocacy matters
- Extended reach: Employees’ personal networks often include passive candidates who may not be actively job hunting but are open to opportunities.
- Authentic messaging: Job posts shared by employees feel more genuine and trustworthy than corporate ads.
- Cost efficiency: Leveraging existing employee networks reduces reliance on paid job advertising.
Strategies to harness social media for recruitment
- Develop a social referral strategy: Encourage employees to share job openings and content on various platforms. Provide clear guidelines to maintain consistent messaging.
- Create advocacy toolkits: Equip employees with content packs, branded templates, and regular nudges to make sharing easy and engaging.
- Leverage social amplification: By tapping into employee networks, you can exponentially increase job visibility, attracting candidates from a broader and more diverse pool.
- Showcase company culture and values: Use social media to highlight your organisation’s unique culture. DEI initiatives, and benefits like hybrid or remote work options, factors that can help attract and retain top candidates.
While our research shows that paid listings are rated as the most effective hiring channel, social media is growing as a tool to attract candidates, both for SMEs and larger businesses.
