Recruitment agency explained

A recruitment agency acts as a hiring partner between a company and potential candidates. The company has a role to fill. The agency helps define the search, identify relevant people, approach candidates, qualify interest and support the hiring process.

In some cases, an agency works mainly with active applicants. In other cases, especially for specialist or senior roles, the agency proactively approaches people who are already employed and not actively applying.

What do recruitment agencies do?

The exact scope depends on the agency and the agreement, but most recruitment agencies support several parts of the hiring process.

Recruitment agencies help companies turn a hiring need into a structured search. That usually starts with clarifying the role, understanding the must-have experience and building a candidate profile that reflects the actual business problem.

Once the profile is clear, the agency searches the market, approaches relevant people and qualifies whether they have the right background, motivation and expectations. The strongest agencies do not simply send CVs. They explain why a candidate is relevant and where the possible risks are.

A recruitment agency can also support the process after the shortlist is created. This includes coordinating interviews, collecting feedback, keeping candidates engaged and helping both sides move toward a clear decision.

How recruitment agencies work

Most searches start with an intake conversation. The agency needs to understand the business, the role, the hiring problem, the market and the reason the role exists. A weak brief usually creates weak shortlists.

After the brief, the agency maps the market and starts outreach. Strong agencies do not simply forward CVs. They test whether candidates match the real hiring need, understand the candidate’s motivation and explain why each person may or may not be relevant.

When should a company use a recruitment agency?

A recruitment agency is useful when the role is important, the candidate market is difficult to reach or the internal team does not have enough time, network or hiring expertise to run the search properly.

For sales roles, external support can be especially valuable because the best candidates are often already employed, selective and not actively applying to job ads.

Types of recruitment agencies

Not every agency works in the same way. Understanding the model helps companies choose the right partner.

  • Generalist recruitment agencies
    Support a wide range of roles across different functions and industries. They can be useful for broad hiring needs, but may have less depth in specialist roles.
  • Specialist recruitment agencies
    Focus on a specific function, market or seniority level. For example, a sales recruitment agency understands sales roles, sales performance signals and candidate motivations in commercial positions.
  • Executive search firms
    Usually focus on senior leadership roles, confidential searches or hard-to-reach candidates. The process is often more research-heavy and targeted.
  • Temporary or staffing agencies
    Help companies find temporary, contract or flexible workers, often for operational or high-volume hiring needs.
  • Contingency agencies
    Usually receive a fee only when a candidate is hired. This can work well for some roles, but the depth of search may vary between providers.
  • Retained or engaged search partners
    Work with more commitment from both sides, often using an upfront or staged fee. This model is common when the search requires focus, market mapping and proactive headhunting.

What to check before working with an agency

Before choosing an agency, look at how well they understand the role beyond the job title. A useful recruitment partner should ask about business context, team structure, success criteria and the type of candidate who would realistically perform in the position.

It is also important to understand how the agency will search. Some agencies rely mostly on active applicants, while others actively map the market and approach people who are not currently applying. The right approach depends on the importance and difficulty of the hire.

Finally, check how the agency communicates. Strong partners give honest market feedback, screen for motivation and fit, and keep the process clear. If the role is in sales, they should also understand the difference between roles such as SDR, BDR, AE, BDM and Sales Manager.

HEMES perspective

At HEMES, recruitment is most effective when the agency understands the commercial reality of the role. A sales hire is not only a person with sales on their CV. The right candidate needs to match the company’s sales cycle, market, buyer type, targets, team stage and expectations for ownership.

That is why sales recruitment benefits from a specialist approach. It reduces noise, improves qualification and gives companies a clearer view of what the market can realistically provide.

I had an amazing time working together with David, seeing his journey through SDR, then team lead then Account Executive, and learning things fast was incredible. A marketing background is a great addition to David skillsets, he's great with any sort of tech stack which is another great skill of his, not to talk about the ability to sell to any type of the business. Highly recommended to any senior sales-type roles!
