Internal vs External: Smart Decisions When Hiring Devs

Written by Strider Staff | July 10, 2025

Choosing between internal and external hiring is a strategic decision. Whether you’re filling a leadership role or expanding your tech team, understanding the differences between both recruitment models can help you allocate time, effort, and resources wisely.

In this article, we’ll walk through the pros and cons of each approach, when to use them, and how to build a structured hiring process that works for your company’s needs.

Difference Between External and Internal Hiring

Internal and external hiring represent two distinct strategies for filling open roles, each with its own process and implications.

Internal hiring happens when an existing employee steps into a new position, either through a promotion or a lateral move. Since the person is already part of the organization, there’s no need to engage in external sourcing. This often shortens the time to hire and reduces onboarding friction.

External hiring, on the other hand, brings in candidates from outside the company. To attract the right talent, the HR team may rely on job postings, social media outreach, referrals, recruiting events, or agency partnerships. 

Unlike internal moves, this approach introduces new perspectives but usually requires more time and resources to find the right match.

Pros and Cons of Each Recruitment Model

Before choosing between hiring options, it’s worth stepping back to evaluate the advantages and limitations of each.

Neither model is inherently better than the other, but understanding their trade-offs allows managers to make decisions that align with the timing, needs, and goals of your company.

Internal Hiring: Pros

  • Faster turnaround: internal candidates are easier to reach and often require fewer steps in the selection process, which helps when the role needs to be filled quickly.
  • Familiarity with the company: they already understand the business model, internal workflows, and company culture.
  • Simplified vetting process: reference checks and performance insights are readily available through their current team.
  • Proven track record: the candidate’s performance history within the company offers a level of predictability.
  • Shorter onboarding period: the transition is smoother since they’re already integrated into the organization.
  • Positive internal signal: promoting from within reinforces the idea that employees can grow in the company, which can improve morale, retention, and even enhance the company’s reputation.

Internal Hiring: Cons

  • Limited candidate pool: relying solely on internal options can reduce diversity of thought and innovation.
  • Backfilling challenge: moving someone internally means opening up their previous position, which could trigger another round of hiring.
  • Managing expectations: employees who applied but weren’t selected might need extra support to stay engaged and productive.

External Hiring: Pros

  • Access to a broader talent market: bringing in external candidates gives you more options to find someone whose experience and skills are a close match to the role.
  • Fresh perspectives: new hires often contribute new ideas based on different professional experiences.
  • Competitive insights: people coming from other companies, including competitors, can provide valuable context or strategies.
  • Opportunity for strategic change: a new hire can be the catalyst for adjusting team dynamics or introducing new workflows.
  • No internal disruption: unlike internal moves, bringing someone from outside doesn’t trigger a vacancy elsewhere in the company.
  • Stronger fit for specialized roles: in cases where the internal talent pool lacks the required experience, external hiring may be the only realistic path.

External Hiring: Cons

  • Higher investment of time and resources: recruitment, interviews, onboarding, and training all require significant company bandwidth and budget.
  • Slower return on investment: it can take months before a new hire starts delivering value at full capacity.
  • Longer ramp-up period: external candidates need time to learn the company's systems, tools, and internal network.

Strategies to Recruit External Hires

External hiring requires more time and coordination than internal moves, which makes it essential to approach it with structure and foresight.

Without a clear plan, companies risk wasting time, money, and even damaging their reputation among candidates.

These strategies help streamline the process while maintaining a strong employer brand.

Select the right acquisition channels

Start by identifying where the role will be promoted — whether it’s job boards, media campaigns, referral programs, or career events.

Each channel has its cost and reach, so tracking where qualified applicants come from will give you better direction for future hires.

Protect and Promote Your Employer Reputation

In the tech world, word spreads quickly. Candidates often share their experiences, especially the negative ones.

A hiring process that feels disorganized or dismissive can discourage future applicants and hurt your standing in the market.

Prioritize Transparency and Efficiency

Build a process that evaluates both technical skills and cultural fit with speed and clarity

Make use of tools that centralize communication and candidate data so that all decision-makers stay aligned and applicants aren’t left in the dark.

Close the Loop With Unsuccessful Candidates

Failing to communicate with candidates who invested time in your process sends the wrong message.

Providing timely, respectful feedback preserves goodwill and reflects positively on your brand, even if someone wasn’t the right fit this time.

Deliver a Well-structured Onboarding Experience

Once the hire is made, ensure that the onboarding process helps them understand their responsibilities and start contributing early.

A new employee who feels supported from day one is more likely to stay engaged and perform well.

Strategies for Internal Hiring

Choosing an internal candidate doesn’t eliminate the need for structure. In fact, a well-defined internal hiring process helps maintain fairness, manage expectations, and reduce the risk of perceived favoritism.

A clear framework not only protects your decision but also reinforces trust in your company’s growth opportunities.

Start With a Job Description

Define what the role demands in terms of skills, responsibilities, and expectations. This ensures that internal applicants understand what’s required and helps reduce assumptions based on tenure or relationships.

Maintain Transparency With Current Leadership

If an internal candidate is under consideration, their current manager needs to be looped in early.

Giving them time to prepare for a potential departure allows for better planning and reinforces internal alignment.

Clarify the Recruitment Steps

Even for internal candidates, outline the full process. Whether it involves technical assessments, interviews with peers, or a final decision panel, make the timeline and expectations visible from the start.

Leverage Performance Insights

Use your access to their current leadership and HR records to evaluate how the candidate handles feedback, collaborates with others, navigates challenges, and contributes technically.

These qualitative insights can often carry more weight than a resume or test score, and help Hiring Managers make informed decisions.

When to Use Internal and External Hiring

There’s no universal answer when deciding between internal and external recruiting. Each open role comes with its own context, urgency, and long-term goals.

In some cases, promoting from within supports continuity and rewards loyalty. In others, bringing in external talent opens the door to fresh ideas and specific expertise. Many companies even combine both approaches — starting with internal outreach and expanding the search if no strong fit emerges.

The most effective hiring strategies remain flexible, aligning with what the business needs at that specific point in time.

Final Thoughts

Internal and external hiring each offer clear advantages and potential drawbacks.

What matters most is matching your strategy to the role at hand and maintaining a consistent, transparent process that supports long-term results.

By treating every hire as a business-critical decision, you increase your chances of finding the right person at the right time, regardless if they're already on your team or just about to join it.

Whether you're hiring externally or promoting from within, success starts with finding the right fit. See how Strider helped Blue River build the team they needed.
