Selection is the cheapest retention intervention available, and it is the one most hospitals do worst. Nearly a quarter of newly hired registered nurses leave within a year, and first-year departures account for 29 percent of all separations — much of which is a mismatch on shift, unit, or expectations that a better interview would have surfaced before the offer.
Structure the interview
The evidence here is old, large, and consistently ignored. Across decades of personnel selection research, structured interviews predict job performance roughly twice as well as unstructured ones. The most-cited synthesis puts structured interviews at the top of the validity hierarchy alongside general mental ability, and unstructured conversation well below.
Structured means: the same questions, in the same order, for every candidate for the role; agreed in advance; scored against a defined rating scale; by interviewers who record ratings before discussing them.
That last clause does most of the work. An unstructured panel converges on whoever spoke most confidently, and the discussion afterwards manufactures the reasons.
What to assess in a nurse
Four things predict whether a nurse will be safe and stay, and none of them is answered by "why did you become a nurse?"
Clinical judgment. Present a deteriorating patient and ask what they notice, what they do, and in what order. You are listening for assessment before intervention, and for the recognition that something is wrong before the numbers say so.
Prioritization under load. Give a realistic four- or five-patient assignment with three competing demands and ask what happens first. There is no single right answer; the reasoning is the signal.
Escalation. Ask about a time they were worried and the physician or charge nurse disagreed. What a nurse does when they are overruled and still uneasy is the closest thing to a safety culture test that fits in an interview.
Delegation and teamwork. Particularly for roles supervising assistants or practical nurses. See scope of practice.
Situational questions ("what would you do if…") and behavioural questions ("tell me about a time when…") both work when scored consistently. Behavioural questions favour experienced candidates; situational questions are fairer to new graduates, who have fewer stories.
Include the people they will work with
Peer interviews — two or three staff nurses from the unit, with their own structured questions — do two things. They assess fit against how the unit actually runs, and they give the existing team ownership of the hire, which measurably improves how a new nurse is received.
The manager keeps the decision. The peers get a real say and an honest explanation when it goes the other way.
Tell them the truth about the job
A realistic preview lowers early turnover, and it works by losing you some candidates on purpose. Say the ratio. Say how often the unit runs short. Say what the call and weekend requirement really is, and what the orientation is actually like rather than what the brochure says.
A shadow shift is the strongest version of this and is worth the disruption for hard-to-fill posts. A nurse who spends four hours on the unit and still wants the job is a different prospect from one who has seen a conference room.
The alternative is discovering the mismatch at week six, at $60,090 a departure.
What you may not ask
Salary history. Eighteen states and the District of Columbia now restrict employers from asking about or relying on a candidate's prior pay, with penalties in some jurisdictions running well into six figures. Two more restrict it for public employers. If your recruiters use a national script, it needs to be the compliant one everywhere.
Anything that probes a protected characteristic, including the familiar traps: childcare arrangements dressed up as a scheduling question, health or disability questions before an offer, and "how long do you plan to keep working?" to an older candidate.
Anything you would not ask every candidate. Which is the point of structure.
Decide quickly
Nurses interview in parallel. At 78 days to fill an average experienced post, a two-week gap between the interview and the offer is not a neutral delay — it is the interval in which someone else hires them.
Agree the decision timetable before the first interview, get the peer feedback in within 24 hours, and have the offer authority in the room or on the phone. Most hiring delay in healthcare is internal approval, not deliberation. See recruitment metrics.
