Interval Guide: Choosing the Right Recruitment Model for Your Hiring Needs

At Interval Group, we know that no two hiring needs are the same. Some organisations need specialist contractors at short notice, others want long-term employees to grow with their business, while some prefer full-service project delivery or outsourced solutions. Choosing the right recruitment model can save time, reduce costs, and ensure you get the right talent exactly when you need it.

In this article, we explore the main types of recruitment models and how to decide which one best fits your goals — with examples and insights relevant to local and international employers alike.

1. Contract / Freelance Recruitment

Hiring contractors or freelancers offers flexibility — ideal for project-based work, short-term gaps, or specialist expertise that doesn’t justify a full-time headcount.

When to use:

• You need a specific skillset for a defined period

• Workload fluctuates or funding is project-based

• Speed and flexibility are key

Advantages:

• Fast onboarding

• No long-term employment costs or commitments

• Access to highly skilled professionals on demand

Considerations:

• Higher daily or hourly rates

• Requires clear scope and deliverables

• Can limit knowledge transfer if not managed well

2. Permanent Recruitment

Permanent recruitment suits roles where you need long-term commitment, cultural alignment, and growth potential. These are often strategic hires — managers, technical specialists, or leadership roles — where the value lies as much in stability as in capability.

When to use:

• You’re investing in someone for the long term

• You have time for a thorough hiring process

• You need a candidate who can grow with the company

Advantages:

• Strong cultural fit and loyalty over time

• Predictable employment costs

• Helps build institutional knowledge

Considerations:

• Longer hiring timelines

• Less flexibility to scale up or down quickly

3. Executive Search

Executive search is a targeted, research-driven model for senior, niche, or confidential appointments. It involves proactive headhunting rather than reactive advertising.

When to use:

• You’re hiring C-suite or senior management

• The role requires discretion or market mapping

• Talent is scarce or highly competitive

Advantages:

• Access to passive, high-calibre talent

• Discreet and strategic approach

• Comprehensive assessment and referencing

Considerations:

• Longer timelines and higher fees

• Requires strong partnership with the search firm

4. Retained vs Contingent Recruitment

Recruitment can be managed either on a retained or contingent basis:

• Retained: You engage one agency exclusively, often with an upfront fee. The consultant acts as an extension of your business, managing the full process end to end.

• Contingent: You brief multiple agencies, and only the one that delivers a successful placement gets paid.

  
  

When to use retained:

• You want a dedicated partner and deeper candidate engagement

• You’re hiring a senior or sensitive position

• Quality and fit matter more than speed

When to use contingent:

• You need to fill multiple roles quickly

• The talent pool is wide and competitive

• You prefer a low-commitment model

Advantages of retained:

• Higher quality shortlists

• Market insight and consistent messaging

Advantages of contingent:

• Fast access to active candidates

• No upfront costs

5. Recruitment Process Outsourcing (RPO)

RPO involves outsourcing all or part of your recruitment process to a third party. It’s often used by larger organisations looking to streamline hiring across multiple functions or regions.

When to use:

• You have ongoing, high-volume hiring needs

• You want consistency and compliance across regions

• You need to reduce internal HR workload

Advantages:

• Scalable and cost-efficient

• Access to data, technology, and market intelligence

• Frees up internal HR for strategic tasks

Considerations:

• Less direct control

• May not suit smaller or one-off hiring needs

6. Consulting (Project-Based or Statement of Work (SOW))

For organisations focused on deliverables rather than headcount, a Statement of Work (SOW) approach may be best. Instead of hiring individuals, you engage a consultancy or managed service provider to deliver defined outcomes — from digital transformation projects to compliance reviews.

When to use:

• You want accountability for delivery, not just talent supply

• Projects are complex, time-bound, or regulated

• You need specialist teams with measurable outputs

Advantages:

• Clear commercial structure (pay for outcomes)

• Reduced administrative burden

• Lower compliance risk

Considerations:

• Higher cost if mis-scoped

• Requires clear deliverables and governance

How to Decide: The Key Questions

Choosing the right recruitment model starts with understanding your goals:

1. What’s the urgency? – Do you need someone tomorrow or can you take your time to find the perfect fit?

2. Is the role permanent or project-based? – Are you filling a gap or building long-term capability?

3. What’s your budget and risk appetite? – Are you ready for permanent commitments or prefer flexible cost models?

4. How much control do you want? – Would you rather manage recruitment internally or outsource it completely?

5. Where will the person work? – Local, hybrid, or cross-border hiring can all affect compliance and model choice.
