Comparing Internal and External Recruitment
| Feature | Internal Recruitment | External Recruitment |
|---|---|---|
| Cost | Low. Minimal advertising costs and no agency fees are required. | High. Involves costs for advertising, recruitment agency fees, and a longer selection process. |
| Speed | Quick. The pool of applicants is small and they are readily available within the business. | Slow. The process involves advertising, shortlisting from a large pool, and longer notice periods for employed candidates. |
| Applicant Pool | Limited to existing employees within the organisation. | Large and diverse, drawn from the wider local, national, or international labour market. |
| Introduction of New Ideas | Limited. Candidates already share the existing company culture and perspectives. | High. New employees bring fresh ideas, different experiences, and new skills to the business. |
| Impact on Morale | Can be positive, as it shows career progression opportunities. Can be negative for unsuccessful internal candidates. | Can be demotivating for existing staff who feel overlooked for promotion opportunities. |
| Risk | Low. The candidate's work ethic, personality, and abilities are already known to the business. | High. The new hire is an unknown quantity and may not fit the company culture, potentially leading to failure in the role. |

The Foundation: Job Analysis, Job Descriptions and Person Specifications
Effective recruitment begins not with an advert, but with a thorough job analysis to confirm the need for a new employee and to understand the role's requirements. This analysis produces two essential documents. The first is the job description, an objective, written statement detailing the duties, tasks, and responsibilities of the post. It includes the job title, reporting structure, main purpose, and key accountabilities. The second is the person specification, which focuses on the ideal candidate. It outlines the necessary qualifications, skills (e.g., technical, communication), experience, and personal attributes (e.g., leadership, teamwork) required to perform the job successfully. These documents are the bedrock of the process; a vague job description attracts unsuitable applicants, while an unrealistic person specification deters qualified ones, wasting valuable time and resources.

Sourcing Talent from Within: Internal Recruitment
Internal recruitment involves filling a vacancy with an existing employee from within the business, either through promotion or a sideways move. Common methods include advertising on internal notice boards, via the company intranet, or through internal newsletters and staff emails. The principal advantages are that it is generally quicker and significantly less expensive than seeking external candidates. The applicant is a known entity, already familiar with the business culture, procedures, and objectives, which reduces induction time and risk. Furthermore, it can be a powerful motivator for staff, who see clear opportunities for career progression. However, a major drawback is the limited pool of applicants, which may mean the best possible candidate is not appointed. It can also create resentment among unsuccessful internal candidates and stifle the introduction of new ideas and skills from outside the organisation.
Methods include internal adverts, company intranet, staff newsletters, and word of mouth.
Advantages: Cost-effective, quicker, candidate is known, boosts morale, lower induction needs.
Disadvantages: Limited applicant pool, can cause internal conflict, stifles new ideas, creates another vacancy to fill.
Casting the Net Wider: External Recruitment
External recruitment involves seeking candidates from outside the organisation. This approach is essential when a business is expanding, requires skills not currently present internally, or wishes to inject fresh perspectives. A wide range of methods can be used, including online job boards (e.g., LinkedIn, Indeed), specialist recruitment agencies, advertisements in newspapers and trade journals, university 'milk rounds', and social media campaigns. The main advantage is access to a much larger and more diverse pool of applicants, increasing the chance of finding the best possible candidate with new skills and ideas. However, external recruitment is typically more time-consuming and expensive due to advertising costs and agency fees. There is also a greater risk involved, as the new employee is an unknown quantity and may not fit into the company's culture, potentially leading to higher staff turnover if the wrong choice is made.
When evaluating recruitment methods, always consider the context provided in the case study. For a senior management role requiring specialist skills, external recruitment via a headhunter might be most appropriate. For a junior supervisory role, internal promotion could be more effective and motivating. Justify your choice.
The Selection Process: From Application to Offer
Once applications are received, the selection process begins. This is a systematic procedure for choosing the most suitable candidate. The first stage is shortlisting, where applications (CVs and application forms) are reviewed against the person specification to create a smaller, manageable list of candidates to take forward. Following this, various selection methods are employed. The most common is the interview, which can be one-to-one, a panel interview, or a telephone/video call. To gain a more objective measure of a candidate's abilities, businesses often use testing. This includes psychometric tests (assessing personality), aptitude tests (measuring specific skills), and for some roles, intelligence tests. For management or graduate positions, an assessment centre might be used, involving a series of tasks, group exercises, and presentations over a day or two to observe candidates in various work-related situations.
Shortlisting is the process of reducing the number of applicants to a manageable number for interview, based on the person specification.
Interviews are a core selection method but can be subjective if not well-structured.
Testing (psychometric, aptitude) provides objective data on a candidate's skills and personality.
Assessment centres offer a holistic view of a candidate's performance in simulated work scenarios.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
A hotel needs a new front desk manager quickly. Current supervisor is capable but lacks formal leadership training. Recommend internal vs external recruitment.
- 1
Internal (promote supervisor):
- Fast, knows systems/culture, motivates others seeking promotion. − Needs leadership training (2.1.6); creates vacancy at supervisor level.
A software company needs a new Senior Developer with a salary of $80,000. It can promote an internal Junior Developer or hire externally. Using the data below, calculate the total cost for each option and recommend which to choose.
External Recruitment Data:
- Recruitment agency fee: 15% of annual salary
- Advertising costs:
- Management time for interviews (40 hours @
Internal Recruitment Data:
- Management time for internal process (10 hours @
- Advanced training course for promoted employee:
- Cost to recruit a replacement junior developer (backfill):
- 1
Step 1: Calculate the total cost of external recruitment. This involves adding the agency fee, advertising, and management time.
- Agency Fee: 15% of 12,000
- Advertising Costs:
- Management Time: 40 hours * 4,000
- Total External Cost = 2,000 + 18,000
