Let’s run a detailed analysis on the different sources of recruitment, their importance, and methods to make informed choices on the source of recruitment that can bring the best talent on board.
What Are the Sources of Recruitment?
The sources of recruitment meaning are simple, and it states that “It is a bunch of methods and channels through which talented candidates are identified and attracted for employment in a particular company that is looking for human resources to run their business operations.” The sources of recruitment are further categorised into internal and external sources of recruitment.
Although the end goal of all types of sourcing in recruitment is to hire top candidates to fill vacant job positions, the effectiveness, and the scale it can reach vary drastically. Additionally, the method of applying for jobs by candidates also contributes to the choice of source through which companies prefer to hire top talent to run their business operations seamlessly.
Why Are Sources of Recruitment Important?
The 5 key reasons that shed light on the importance of sources of recruitment include:
1. Aligns with Business Hiring Goals
The sources of recruitment in HRM help organisations target the right candidates based on role type, urgency, and skill level. A robust source of recruitment ensures the onboarded candidate’s skills and expertise align with the company’s workforce planning and growth strategy.
2. Influences Talent Reach and Diversity
The different sources of recruitment tap into a wide talent pool, ideal for filling immediate and long-term roles. This enables broader reach and enhances diversity across locations, industries, and experience levels.
3. Determines Hiring Speed and Volume
The sources of the recruitment and selection process directly impact hiring speed and volume, which is crucial for bulk hiring in a short time.
4. Impacts Candidate Experience
Where and how job-seeking candidates discover job opportunities shapes their first impression. Strong sourcing channels ensure a professional, accessible, and engaging candidate journey from the start to onboarding.
5. Affects Long-Term Employee Retention Rates
Top talent sourced from the right hiring channels is more likely to stay in a firm for longer term, reducing turnover and facilitating in building of a stable, high-performing workforce over time.
What Are the Types of Internal Sources of Recruitment?
When we try to explain the internal sources of recruitment in layman’s terms, it simply states that ” The internal sources of recruitment are the ways to fill the vacant positions from the talent within the organisation or find talent through the support of the internal workforce”.
Here are a few internal sources of recruitment in HRM that companies use to recruit the right candidates for vacant roles.
- Employee Referrals: It is an interesting method used as an internal source of recruitment, as the candidates are hired outside the company, similar to external sources of recruitment, but the employees working within the organisation act as a catalyst to provide a ready list of candidates matching the JD through their network.
- Promotions: Employees within the company are elevated to higher positions that are vacant based on eligibility, performance, skills, and expertise.
- Transfers: In this mode, employees from one department or branch are transferred to another department or location to fill a critical position. In most cases, the designation remains the same.
- Succession Planning: Here, the company’s board of directors or the decision-making committee identifies the next set of leaders from the current pool of eligible employees capable of managing all the responsibilities and ensuring continued business growth in a challenging environment.
- Internal job posting: Here, the company puts an advertisement within the work premises through emails, internal newsletters, etc. The eligible employees can apply and get an interview opportunity.
What Are the Types of External Sources of Recruitment?
The external sourcing strategies involve hiring channels that fall outside the periphery of an organisation. The methods adopted by the recruitment don’t involve any active participation of internal employees.
Here are the key external sources of recruitment:
- External recruitment online platforms: The hiring team will run job-related advertisements with detailed JDs in various online-based recruitment platforms like Naukri, Indeed, Shine, etc..
- Social media: The HR team or a dedicated social media recruitment team will share job postings with targeted content on different social media platforms like LinkedIn, Facebook, Instagram, or Twitter. These types of sourcing in recruitment are ideal for building both active and passive talent pools.
- Recruitment Agencies: Companies partner with top recruitment agencies like ALP Consulting to hire and onboard top candidates to fill their vacant positions in a short duration.
- Campus Hiring: The company will collaborate with top colleges and universities across India to conduct interviews for final-year graduates and offer them jobs for entry-level roles.
- Walk-ins: The companies will arrange walk-in interviews where the candidates can directly attend interviews within the office premises on the scheduled dates and get a job offer if they successfully crack the interview.
What Factors Influence the Choice of Recruitment Source?
Here are the factors that persuade companies on the choice of internal and external sources of recruitment:
1. Nature of the Job Role
The role complexity, expertise, seniority, and the number of possible candidates available to fill that position (especially for niche roles) determine the choice of sources for recruitment. Usually, companies use multiple types of sourcing in recruitment to increase the chances of hiring the best talent.
2. Urgency of Hiring
If there is a tight deadline to hire a candidate, then internal sources of recruitment seem to be the best choice. For roles that require meticulous planning and specialised expertise, external sources of recruitment in HRM are the best strategy as they offer access to a wider talent pool with diverse expertise.
3. Budget and Cost Constraints
The sources of recruitment and selection are heavily dependent on costs and budget constraints. Social media or internal referrals and promotions are low-cost sourcing options preferred by companies over job portals or campus hiring, which are a little more expensive.
4. Target Candidate Profile
Intrinsic factors like demographics, location, skill level, and experience of the desired candidates shape whether digital platforms, campus drives, or niche job portals are the most effective sources of recruitment in HRM.
5. Company Size and Brand Recognition
Companies with high brand value may attract applicants through organic channels, while start-ups or lesser-known firms may rely more on recruitment partners, social media marketing, or job fairs to attract talent.
6. Geographical Reach and Scalability
Recruitment across multiple regions or countries may require global job portals, RPOs, or outsourcing firms that can provide access large talent pool that is ready to be hired for filling both domestic and overseas job requirements.
