Internal recruitment is filling an open role with someone who already works for you, through a promotion or a transfer. It is usually faster, but every internal move opens another seat.
| Internal | External | |
|---|---|---|
| Time to fill | Often shorter, candidate already known | Longer, includes sourcing and screening |
| Ramp-up | Knows the systems and people | Needs full onboarding |
| New skills | Limited to what the team has | Can bring in skills the team lacks |
| Side effect | Opens another seat to backfill | Can frustrate staff who wanted the role |
Most employers use both. A common rule is to post internally first for a set number of days, then open externally.

A hotel’s night manager resigns. The general manager promotes a front desk agent who has covered nights for a year. Her front desk seat is filled by a part-time night auditor moving to full-time. The part-time auditor shifts are then filled with an external hire.
Three people end up in new roles, but only one is a new hire, at the entry-level position that is easiest to fill and train. The night manager seat was filled in 9 days. The last external search for that role took 34 days and ended with a candidate who left in 4 months.
The plan worked because the hotel mapped the chain before announcing the promotion. Without that, the front desk would have been short for weeks while the general manager celebrated a fast hire.
Internal recruitment works best when you know in advance who could step up. Once or twice a year, ask each manager two questions for every role on their team: who could do this job now, and who could do it within a year with training? The answers make a simple bench list.
Roles with nobody on the bench are your risks. For those, pick one or two people who are interested, give them a development step such as covering shifts, a training plan or shadowing, and check progress at the next review. When a vacancy comes, you start with known candidates instead of an empty list.
A pharmacy chain needs 3 full-time technicians across 2 stores. Before advertising externally, it asks its 11 part-time technicians who wants more hours. Five say yes; the 3 with the strongest reviews move to full-time.
The 3 part-time openings that follow are easier to fill externally and need less training. Over the year, the chain fills 70% of its full-time technician openings from its part-time staff, and full-time vacancies are filled in an average of 12 days instead of 31.
Promoting a shift lead to assistant manager, or transferring a cashier who wants more hours to an open full-time role at another store.
Known performance, faster ramp-up, lower hiring cost and a career path that helps retention.
Fewer new skills and ideas, a backfill chain to manage, and resentment if the process is not seen as fair.
No. A posting is one way to recruit internally. Internal recruitment also covers direct approaches and succession plans.
Usually for the role being filled, because sourcing and onboarding costs are lower. Remember to count the cost of backfilling the seat the internal candidate leaves.
Many employers interview every qualified internal applicant. It shows the process is real and gives each person useful feedback.
