| Best Fit For | Predictable, steady hiring with strong internal capability | Rapid growth, mass hiring, or new market entry | Evolving hiring needs with limited internal bandwidth |
How to choose the right model
- Analyse hiring volume & forecast – high fluctuation = RPO/Embedded.
- Assess internal capability – strong internal HR favours In‑House.
- Cultural fit importance – Embedded = highest alignment.
- Cost vs speed vs quality balance – Embedded offers sweet spot if culture + efficiency matter.
Trial support – consider pilot embedded recruiter for 3–6 months to see impact.
If embedded recruitment sounds like the right fit, this guide breaks down how the model works — and what to consider when comparing different recruitment models across cost, control, and candidate quality.

Comparing different recruitment models
In‑House suits low-volume, high-control hiring; RPO offers scalability and expertise for fluctuating needs; Embedded Recruitment blends internal alignment with agency flexibility, reducing time‑to‑fill and boosting quality.
Each model has trade‑offs in cost, control and cultural fit. Let’s dive in.
1. What is In‑House Recruitment?
Internal Talent Acquisition teams manage the full hiring process.
- Pros: Full control, deep cultural fit, employer brand alignment.
- Cons: Limited scalability, headcount constraints, less external insight.
In-house recruitment works well for companies with predictable, ongoing hiring needs and enough internal resources to support the entire recruitment lifecycle. For instance, a stable financial services company hiring for recurring roles (like analysts or account managers) may prefer to manage talent acquisition directly. This model offers the highest level of control and internal cultural alignment, but may falter during peak periods or when specialised skills are needed.
2. What is RPO (Recruitment Process Outsourcing)?
A provider handles all or part of the TA cycle under contract.
- Pros: Flex capacity, expertise, tech‑driven analytics.
- Cons: Less integration, potential misalignments with culture, upfront costs.
RPO solutions are ideal for organisations facing rapid growth, mass hiring, or expansion into new markets. Think of a retail chain opening multiple locations or a logistics company during peak seasons. RPOs can scale quickly and deliver high-volume talent pipelines. However, they may feel transactional and disconnected from internal teams, especially if employer branding and candidate experience are priorities.
3. What is Embedded Recruitment?
Recruiters sit within your TA team as strategic partners
- Pros: Cost predictability & efficiency: Embedded models often reduce costs by 40–70 % and save over 80 recruiter‑hours/month
- Cultural alignment: Recruiters learn your values, improving quality of hire and retention
- Speed: Time‑to‑fill cut by 50 % compared to traditional agency models
- Cons: Requires core team buy‑in, may not fit adhoc hiring.
Embedded recruitment is perfect for companies with steady but varied hiring needs who lack the internal bandwidth to manage them effectively. Our embedded teams work with exactly these clients: we integrate within their systems and processes, act as a strategic partner, and handle everything from sourcing to onboarding. This model combines agency-level scalability with the familiarity and alignment of an in-house recruiter.

A real-world example of embedded recruitment in action comes from Glan Agua, a water infrastructure company operating across Ireland and the UK. Facing talent shortages, they partnered with Rent a Recruiter, who embedded recruiters within their team. Over 17 months, they engaged 8,000+ passive candidates and presented 180 qualified applicants — significantly boosting hiring outcomes.
This case is highlighted in AIHR’s guide to top recruiting strategies for 2026, which cites embedded partnerships as a best practice for companies seeking both flexibility and talent impact.
This use case demonstrates the benefits uncovered when comparing different recruitment models in real-world settings — particularly for organisations with project-based or region-specific hiring needs.
Comparing different recruitment models, how do costs compare?
-
In‑House: Salary, benefits, ATS fees. High fixed cost, limited scale.
-
RPO: Modular pricing; pay per hire or slot. More predictable but can balloon with overspend.
-
Embedded: Often flat or scalable retainer; lower total cost per hire. Often 40-70% cheaper than traditional commissioning fees.
