Latest / Hiring & Firing with Fexingo: Recruitment, Performance, and Workforce Decisions / Why Internal Mobility Beats External Hiring Every Time
Transcript
- Lucas: So here's a number that stopped me this week. LinkedIn's 2025 Workforce Report found that employees who move internally are 24 percent more likely to stay with the company for at least three years, compared to someone hired from the outside. Luna: And that's not just about retention — it's about performance too, right? Lucas: Exactly. Internal hires hit full proficiency about 40 percent faster than external hires. That's according to the same dataset. They know the systems, the culture, the unspoken norms. They don't need three months to figure out which Slack channel actually gets decisions made. Luna: Forty percent faster — that's almost half the ramp time. So the productivity gap is real. Lucas: And it compounds. The report also showed that companies with strong internal mobility programs see 18 percent higher overall productivity from their workforce. Not from any one hire — from the whole organization. Luna: So why don't more companies do this? I feel like the default is still to post a job externally, even when there's a perfectly good candidate two floors up. Lucas: Partly it's inertia. But partly it's a structural problem. Most companies don't actually know what skills exist inside their own walls. Managers hoard talent because they don't want to lose a good performer. And the systems — applicant tracking systems — are built for external candidates. They don't surface internal talent. Luna: You're saying the technology itself is biased toward external hiring. Lucas: Completely. The typical ATS treats an internal applicant almost the same as an external one — same workflow, same resume parse, same screening questions. But an internal candidate's resume doesn't capture their institutional knowledge, their relationships, their track record inside the company. So they get filtered out just as often. Luna: Which is insane, because the internal candidate already has a performance history you can verify. Lucas: Right. And yet, the data from a 2024 Gartner survey showed that only 22 percent of organizations have a formal internal mobility program with dedicated resources. The rest rely on word of mouth or manager discretion. Luna: So most companies are leaving 78 percent of the opportunity on the table, roughly. Lucas: And it's not just about cost savings. It's about reducing bias. External hiring has all kinds of well-documented biases — affinity bias, credentialism, overvaluing pedigree. Internal mobility sidesteps a lot of that because you're judging someone on actual performance, not on a resume. Luna: But isn't there a risk of inbreeding? Of not bringing in fresh ideas? Lucas: That's the classic counterargument, and it's valid — to a point. The best internal mobility programs are balanced. You still hire externally for roles where you genuinely need new thinking. But the default should be internal. Think of it like a farm system in baseball. The major league team doesn't go out and sign a free agent for every open slot. They develop players from within. Luna: And they supplement with external talent when there's a gap. Lucas: Exactly. Procter & Gamble is the canonical example. They've built their entire culture around promoting from within. Almost every senior leader started there as an entry-level employee. And they've consistently outperformed competitors on both retention and innovation metrics. Luna: What about the technology side? Are there tools that actually help? Lucas: A few. There's a newer category of talent marketplace platforms — companies like Gloat and Fuel50 — that let employees express interest in different roles, projects, mentors. They surface hidden skills. But adoption is still low. Most HR departments haven't budgeted for it. Luna: So what's the first step for a company that wants to get better at this? Lucas: I'd say start with transparency. Publish all open roles internally before they go external. Give internal candidates a head start — say five business days. That alone can shift the culture. Then start tracking mobility metrics: what percentage of roles are filled internally? What's the time to fill for internal versus external? And crucially, ask in exit interviews: did you know about other opportunities here? If the answer is no, that's a system failure. Luna: That's such a simple fix. And I imagine it also boosts engagement, because people see a future for themselves. Lucas: Massively. LinkedIn's data shows that employees who are able to move internally are 75 percent less likely to leave the company. That's almost as powerful as a raise. And it costs way less than recruiting a replacement. Luna: I want to circle back to something you said earlier about managers hoarding talent. That seems like the hardest barrier to overcome. Lucas: It is. Because if you're a manager and your best employee gets poached internally, you lose productivity. There's no incentive for you to let them go. So companies need to create incentives. Some firms now tie manager bonuses to internal promotion rates — if you develop talent that moves up, you get rewarded. Luna: That aligns incentives beautifully. Instead of penalizing the manager for losing someone, you reward them for developing people. Lucas: Exactly. And it changes the conversation from 'you're stealing my star' to 'you're giving my star a growth opportunity.' That's a huge cultural shift. Luna: So what does the data say about the actual cost difference? Internal hire versus external hire, all in. Lucas: The Society for Human Resource Management estimates that the average cost per hire for an external employee is about $4,700. For an internal hire, it's roughly $1,000. But that's just the direct cost. The real savings are in time and productivity. External hires take months to ramp. Internal hires are already productive from day one in terms of cultural context. Luna: That's a no-brainer on paper. But in practice, it requires discipline. Lucas: It does. And it requires leadership to model it. If the CEO always brings in external executives, the message is clear: internal mobility doesn't apply at the top. That trickles down. Luna: So the C-suite has to walk the walk. Lucas: Absolutely. One company that does this well is Nvidia. They've historically promoted from within for most senior roles. And they've managed to maintain a very strong culture while also innovating rapidly. They're a good counterexample to the 'fresh blood' argument. Luna: I hear that argument a lot in tech, especially for engineering roles. The idea that you need to hire externally to get the latest skills. Lucas: And sometimes you do. If you need an expert in a brand-new field — say, quantum computing — you might have to look outside. But for the vast majority of roles, the skills can be developed internally. Especially if you invest in learning and development. The payback on that investment is huge. Luna: And it ties into what we talked about a few episodes ago — skills-based hiring. If you're mapping skills internally, you can see who's ready for the next step. Lucas: Exactly. That's the infrastructure piece. You need a skills taxonomy. You need to know what your people know. Most companies don't have that. But the ones that do — like Unilever, IBM — they're seeing real results in both retention and agility. Luna: So if a listener is an HR leader at a mid-sized company, what's one metric they should start tracking tomorrow? Lucas: Internal fill rate. The percentage of roles filled by internal candidates. That's the leading indicator. If it's below 30 percent, you have a mobility problem. The best-in-class companies are above 60 percent. Luna: Sixty percent — that's a high bar. Lucas: It is. But it's achievable. And it's worth pursuing because the alternative — constant external hiring — is expensive, slow, and demoralizing for your existing talent. People want to grow. If they can't see a path, they leave. And then you have to hire externally to replace them. It's a vicious cycle. Luna: It's a retention tool disguised as a hiring strategy. Lucas: That's exactly what it is. And it's one of the few strategies where the HR department and the finance department can agree: it saves money and it builds culture. Luna: Speaking of building culture — if these conversations have helped you think differently about your own team or hiring approach, that's exactly why we keep doing this show. And listener support is what keeps it going without ads. If you've gotten value, you can help at buy me a coffee dot com slash fexingo. Lucas: Yeah, and honestly, every bit helps us keep digging into the numbers and the stories that actually matter. So with that, let's look ahead — next episode, we're talking about the rise of fractional executives. That's a topic where internal mobility meets a whole new talent model. Luna: Fractional executives — part-time C-suite talent. That's going to be a good one. Lucas: It is. But for now, the takeaway: look inside first. Your next great hire might already be on your payroll.
