Recruitment and selection

A person specification is a document that sets out the skills, qualifications, experience and personal qualities required of the ideal candidate for a job — it describes the type of person the business wants to recruit.

One benefit is that internal recruitment is lower-risk because the candidate is already known. The business has seen the employee's work, attitude and reliability, so it can judge their suitability more accurately than for an outside applicant. This reduces the chance of a poor appointment, and it is also cheaper and faster than recruiting externally, although it does not bring in fresh ideas.

The first method is an interview, where the business meets the candidate to discuss their experience and suitability. An interview lets the firm assess communication skills, personality and how well the candidate fits the team, and it can probe the candidate's answers in detail. However, interviews are subjective, so they should not be relied on alone.

The second method is testing — for example aptitude, skills or psychometric tests. Testing gives objective evidence of a candidate's ability that is harder to fake than an interview answer, allowing the firm to compare candidates fairly on the skills the job actually requires.

Using the two together — an interview for fit plus a test for ability — gives a more reliable and balanced selection decision than either method alone.

Internal recruitment fills a vacancy by promoting or moving an existing employee, and it has clear advantages. It is cheaper and faster than external recruitment because there is less advertising and a shorter selection process, and it is lower-risk because the candidate's work and attitude are already known to the firm. It also motivates staff: offering promotion shows employees there is a route to advance, which can improve retention and effort throughout the business.

However, internal recruitment has disadvantages. It brings no new ideas or skills from outside, so a firm needing fresh thinking or a capability it lacks will not gain it. Promoting one employee also creates another vacancy that must then be filled, and it can cause rivalry or resentment among colleagues who were not chosen, which may harm morale.

The better choice depends on the firm's needs. Where the firm wants to motivate staff and keep the appointment low-risk, internal recruitment is preferable. Where it needs new skills, fresh ideas or a wider talent pool — for example for a senior or specialist role — external recruitment is more appropriate despite its higher cost. In practice many firms use both, recruiting internally where they can and externally where they must.

Using an assessment centre — where candidates complete tasks and exercises over a day while assessors observe — offers the bank real benefits. It is the most thorough selection method: it sees candidates actually doing relevant tasks (teamwork, problem-solving, presentations) rather than just describing themselves, which gives a far more reliable picture than an interview alone. For a graduate scheme that the bank invests heavily in, this reduces the risk of a costly bad appointment and helps identify candidates with genuine potential.

However, assessment centres have drawbacks. They are expensive and time-consuming to run, requiring assessors, venues and a full day per cohort. Some strong candidates may underperform in the artificial, high-pressure setting, while confident performers may shine without being the best long-term hires. For a small number of vacancies the cost could outweigh the benefit.

Judgement. For this bank, an assessment centre is likely to be worthwhile specifically because it is recruiting many graduate trainees for an expensive, long-term programme. When the cost of a wrong hire is high and there are many candidates to compare fairly, the thoroughness of an assessment centre justifies its cost. The decision would be less justified for a single, low-level or temporary vacancy, where a CV, interview and references would be enough. So the bank should use an assessment centre for its graduate scheme, but reserve simpler methods for routine roles — the criterion being the importance of the role and the cost of a poor appointment.

Recruitment and selection determine who joins a business, so they shape the quality of its workforce. They are clearly important to success, but whether success depends on them more than on other factors is open to debate.

The case that success depends heavily on recruitment and selection. Getting the right people is the foundation of performance. Effective recruitment attracts strong applicants, and effective selection — using job descriptions, person specifications and a combination of methods — ensures the firm appoints capable, well-matched staff. This raises productivity, quality and customer service, while poor recruitment leads to mis-hires that lower performance, increase labour turnover and waste training. For a service or knowledge-based business, where the workforce is central to what it sells, the quality of recruitment and selection can be decisive. A poor appointment to a senior role can damage the whole firm.

The case that other factors matter more. First, recruitment is only the start: even excellent hires must then be trained, motivated and retained, so HRM as a whole — not just hiring — drives results. Second, success depends on factors outside HR entirely: the product, marketing, finance and operations. A firm with brilliant staff but a product no one wants will still fail. Third, external factors (the economy, competition, regulation) can outweigh the quality of the workforce. Fourth, a good induction, leadership and culture can develop average recruits into strong performers, reducing reliance on perfect selection.

Weighing it up (criterion). How far success depends on recruitment and selection depends on how people-dependent the business is and how skilled its roles are. For firms where skilled people are the competitive advantage (consultancies, hospitals, software houses), it is a major determinant of success. For capital-intensive firms, or where the product or finance is the binding constraint, it matters less.

Judgement. Recruitment and selection are a significant determinant of success — but not the only or always the most important one. They are most decisive for people-dependent, skill-intensive firms, where the right hires create lasting competitive advantage. Even there, however, recruitment must be supported by training, motivation and retention, and by a viable product, sound finance and effective operations. The most defensible conclusion is that good recruitment and selection are necessary for success but not sufficient on their own — they set the workforce's potential, but realising it depends on the rest of HRM and the wider business.
