Short version: A CNA interview turns on three signals — safe patient care (transfers, vitals, infection control, HIPAA), bedside judgment (when to escalate to the RN and how to document), and reliability (attendance, weekends, holidays, and the ability to take a callout shift). Expect a mix of scenario questions ('a resident refuses their bath — what do you do?'), technical questions on ADLs and vitals, HIPAA and abuse-reporting basics, and behavioral questions on teamwork with charge nurses. Below are the twenty questions unit managers, DONs, and home-health supervisors actually ask, with sample answers you can adapt line for line.

How to prep for a CNA interview
Certified Nursing Assistants (BLS occupation code 31-1131) work under a licensed nurse across four main settings: hospitals (medical-surgical, telemetry, ED, ICU), skilled nursing and long-term care (SNF/LTC — the largest employer), home health and hospice, and assisted living. Roughly 1.5 million CNAs work in the U.S., and the interview is remarkably consistent across settings: 20–30 minutes with a unit manager, DON (Director of Nursing), or staffing coordinator, sometimes with a working-interview shadow shift attached. What decides most offers is not the résumé — it's whether you can answer three questions with genuine detail: how you'd handle a difficult resident, how you'd escalate a change in condition to the RN, and how you'd cover a Saturday-night callout without complaint.
Prep three artifacts before the interview:
- Your STAR bank. Six short stories from clinical rotations or prior CNA work — each with a Situation, Task, Action, and Result. Cover a difficult resident, a fall or near-fall, an escalation to the RN, a HIPAA moment, a hard family conversation, and a shift you covered short-staffed.
- Your credentials line. Certification (state, expiration, registry number), BLS/CPR status, TB and immunization status, and any specialty training (dementia, hospice, restorative).
- Two questions of your own. One about the ratio (residents per CNA on days, evenings, nights); one about how the unit escalates.
Six scenario questions (patient-care decisions)
These are the questions that separate CNAs who read the room from CNAs who read the textbook. Every answer should show respect for the resident's dignity, a plan you'd act on, and a moment where you'd loop in the RN.
1. A resident refuses their morning bath. What do you do?
What they're screening for: Do you respect resident autonomy, or do you steamroll it? Do you know how to try again without escalating?
Sample answer: "I'd stop and ask what's going on — sometimes it's pain, sometimes it's cold, sometimes they just want an hour. I'd acknowledge their choice, note the refusal in the CNA notes, and come back mid-morning with a different approach — offer a bed bath, a warm washcloth, or wait until after breakfast when they're more settled. I'd flag the RN if the refusal is a change from baseline or if I see skin breakdown risk, because a bath refusal that turns into three days is a skin-integrity conversation."
2. You walk into a resident's room and find them on the floor. Walk me through the next five minutes.
What they're screening for: Do you assess before you move them? Do you call for help? Do you know your facility's post-fall protocol?
Sample answer: "First, I don't move them until I know why. I'd call for help — pull the cord and call for the nurse — check responsiveness, look for obvious injury (bleeding, deformity, pain), take a set of vitals if I can, and stay with the resident. I'd let the RN lead the assessment. Once cleared to move, I'd use a mechanical lift or two-person assist — never lift solo — and complete the post-fall documentation and neuro checks per protocol. If the resident hit their head or is on anticoagulants, that's a call I'd want the RN to make about sending out."
3. A resident with dementia is agitated and swinging at you during a transfer. What do you do?
What they're screening for: De-escalation. Not restraints. Not force.
Sample answer: "I'd step out of arm's reach, lower my voice, and stop the transfer. Agitation during care is almost always the resident telling me the timing or the approach isn't working. I'd try again in ten minutes with a different lead-in — a familiar song, a photo they respond to, a co-worker they trust. If it's a pattern, I'd bring it to the RN and the care plan meeting because it might be pain, a UTI, or a medication side effect showing up as behavior. Physical restraint isn't my call and isn't the answer."
4. You notice a resident's blood pressure is 178/104 during morning vitals. What's your next step?
What they're screening for: Do you know when to escalate? Do you re-check first?
Sample answer: "I'd re-check on the opposite arm with a manual cuff after five minutes of rest, since automatic cuffs can read high on the first pass. If it's still elevated and above baseline for that resident, I'd document and notify the RN immediately — I wouldn't wait for the end of my rounds. I'd let them know the baseline, the two readings, and any symptoms — headache, chest pain, vision change. That's not a decision I make; it's information the nurse needs to make one."
5. A family member asks you what medications their mother is on. How do you handle it?
What they're screening for: HIPAA. Politely.
Sample answer: "I'd redirect kindly — 'Medication questions are best answered by the nurse; let me grab them for you.' I don't share med lists, diagnoses, or care plan details, even with immediate family, without the RN and without confirming they're on the release. I'd also let the nurse know the family had a question so they can circle back before the family leaves."
6. You're two hours into your shift and realize you're going to be short on time to finish rounds. What do you do?
What they're screening for: Prioritization and communication — not martyrdom.
Sample answer: "I'd re-prioritize by clinical need — anyone with skin-integrity risk, anyone on a two-hour turn schedule, anyone with a swallowing precaution for the meal cart. I'd let the charge nurse know I'm behind and where I might need help, and I'd ask another CNA if they can pick up two of my rooms. I'd rather be honest at hour two than surprised at hour six, and I'd document what got done and what got deferred so the next shift can pick it up cleanly."
Six technical questions (ADLs, vitals, safety)
7. What is a normal range for adult resting heart rate, blood pressure, and O2 saturation — and when would you escalate?
Sample answer: "Normal HR is 60–100, BP under 130/80 for most residents (their own baseline matters more than the textbook), and O2 sat 95% or above on room air. I'd escalate a HR under 50 or over 120, a systolic under 90 or over 160, or a sat below 92% — sooner if the resident has symptoms."
8. Describe how you'd transfer a resident from bed to wheelchair.
Sample answer: "I'd check the care plan for the transfer status — independent, one-assist, two-assist, mechanical lift, or dependent. I'd lock the wheelchair, position it on the resident's stronger side, raise the bed to the resident's mid-thigh, use a gait belt for a stand-and-pivot, and never lift from under the arms. If it's a two-assist or mechanical lift resident, I'd stop and get a second person or the Hoyer. Body mechanics protect the resident and my back."
9. What are the five moments for hand hygiene?
Sample answer: "Before touching a resident, before a clean or aseptic procedure, after body-fluid exposure risk, after touching a resident, and after touching the resident's surroundings. I use soap and water when hands are visibly soiled or after C. diff exposure — alcohol gel isn't enough for those."
10. What does 'ADL' stand for and what do you document?
Sample answer: "Activities of Daily Living — bathing, dressing, grooming, toileting, transferring, and eating. I document what the resident did independently, what they needed cueing for, and what required physical assist. I also document intake, output, and any refusals. Documentation drives the MDS assessment and the resident's care level, so it has to be honest and specific."
11. What are the signs of skin breakdown, and what would you do if you saw a stage 1 area on a resident?
Sample answer: "Redness that doesn't blanch, warmth, tenderness, or a change from baseline. Stage 1 is intact skin with non-blanchable redness. I'd reposition off the area immediately, document what I saw and where, notify the RN, and make sure the two-hour turn schedule is followed on my next round. Skin breakdown is a whole-team problem, but the CNA is usually the first to see it."
12. Walk me through how you'd feed a resident with a swallowing precaution.
Sample answer: "I'd check the care plan for the diet consistency — regular, mechanical soft, pureed — and the liquid consistency — thin, nectar, honey. I'd sit the resident upright at 90 degrees, small bites, alternate solids and liquids, and watch for coughing, throat clearing, or a wet voice. I'd never feed a resident lying flat, and I'd never rush — aspiration risk is the biggest cause of pneumonia hospitalizations from LTC."
Five behavioral questions (teamwork & reliability)
13. Tell me about a time you disagreed with a nurse. How did you handle it?
Sample answer: "I'd never disagree in front of a resident or family. If I felt a call was off — say the RN wanted to send a resident to lunch but I'd just seen them dizzy on transfer — I'd pull them aside privately, share what I saw and my concern, and then defer to their clinical judgment. My job is to give the nurse accurate information; theirs is to decide. I remember one time I flagged a resident's mental status seemed off; the RN checked, and it turned out to be an early UTI. That's the loop that works."
14. Tell me about a time you had to work a double or cover a callout.
Sample answer: "Last February our unit had two callouts on a snow day and I stayed for a double. I paced my breaks, used the second half to catch up on documentation, and asked the charge nurse for a light dinner assignment on the second shift so I could stay sharp for showers and med-pass assist. I don't volunteer for doubles every week — that's how you burn out — but I'll take one when the residents need it."
15. Tell me about a difficult resident or family member and how you built trust.
Sample answer: "One family — a daughter of a resident with advanced dementia — was very anxious and would call the unit three or four times a day. I started sending her a two-sentence update at the end of my morning rounds — 'Mom ate 75% of breakfast, walked to the dining room with a one-assist, and is watching the birds' — and her calls dropped to once a week. She wasn't difficult; she was scared, and she wanted proof someone was paying attention."
16. What's your availability, and how do you feel about weekends and holidays?
Sample answer: "I'm available for the shift you're hiring for, plus every-other weekend, and I can take Thanksgiving or Christmas — I'd rather commit to one and know than promise both and swap. I know CNAs on the floor make the unit run on those days; I want to be a reliable name on the schedule, not the one the DON is chasing."
17. What do you do when you're having a hard day at work?
Sample answer: "I take a five-minute break somewhere quiet, drink water, and reset. If the day is heavy — a resident I'm close to is declining, or we've had a code — I take advantage of the EAP and talk to my charge. I've learned that pretending I'm fine on Tuesday means I'm short on Thursday. Taking care of the residents means taking care of the CNA doing it."
Three HIPAA & ethics questions
18. What is HIPAA and how does it apply to your day?
Sample answer: "HIPAA protects protected health information — anything that identifies a resident and their care. Practically, I don't discuss residents in hallways, elevators, or breakrooms; I don't post on social media about work; I don't share information with family without confirming they're on the release; and I don't leave charts open where visitors can see them. If someone I know casually turns out to be a resident's family friend, I don't share that they're on the unit either."
19. If you suspected abuse or neglect — from a family member or a coworker — what would you do?
Sample answer: "I'm a mandatory reporter. I'd document exactly what I saw or heard, when, and where — no interpretation, just facts — and report it immediately to my DON. If a coworker was involved, I'd still report; I wouldn't confront them first, and I wouldn't wait to be sure. Adult Protective Services or the state ombudsman gets involved when the facility can't act, but the first call is up the chain."
20. If you made a mistake — say, you documented wrong or missed a vital sign — what do you do?
Sample answer: "I tell my charge nurse right away, correct the documentation with a proper late entry (never white-out, never backdate), and think through what changed in my workflow that let it happen — was I short on time, was I distracted, was I asked to double-task? Mistakes are inevitable in this work; hiding them is what harms residents."
Questions to ask the unit manager back
- What are the CNA-to-resident ratios on days, evenings, and nights?
- How does the unit escalate when a CNA sees a change in condition — text, TigerConnect, in-person?
- What's the tenure of the CNA team? (a proxy for how the unit treats staff)
- Is there a career-ladder program — restorative CNA, med-tech certification, LPN bridge, tuition assistance?
- What's the culture around callouts — how do you handle short-staffing without punishing the team that showed up?
Frequently asked questions
Twenty to thirty minutes with a unit manager, DON, or staffing coordinator, sometimes followed by a working shadow shift of 1–4 hours. Long-term care and skilled-nursing employers frequently offer on the spot if the interview goes well and your certification, TB, and drug-screen paperwork are current. Hospitals move slower — usually a second interview with the nurse manager and a formal offer 3–7 days later.
Clean scrubs or business casual — a plain top, dark pants, and closed-toe shoes. Avoid strong fragrance, long nails, or lots of jewelry — the setting is clinical. Bring copies of your CNA certification, state registry printout, BLS/CPR card, TB test, immunization record, and driver's license. For hospital interviews add a printed résumé and a two-line references sheet.
Safe transfers and body mechanics, accurate vitals and reporting, ADL support with dignity, infection control and hand hygiene, HIPAA, de-escalation for dementia and agitation, teamwork with the licensed nurse, and reliability — attendance, weekend coverage, and callout willingness. In hospital settings, add telemetry familiarity, phlebotomy or blood-glucose checks if you have them, and turn-and-position discipline for pressure-injury prevention.
Name something specific about the facility — a Medicare star rating, a specialty unit (dementia, hospice, rehab, memory care), a hospital system reputation, or a location that matches your commute. Then connect it to your goal: 'I want to build hours in memory care because I'm applying to an LPN program that requires 500 supervised hours; this unit's dementia program is the reason I applied here first.' Real reasons beat scripted ones.
Blaming residents for behavior, discussing prior residents by name, treating HIPAA as a formality, dismissing weekend and holiday coverage, being vague about escalation to the RN, and any hint you'd move a fallen resident before assessing. In some settings, gaps in TB clearance, immunization, or lapsed BLS are automatic disqualifiers before the interview even starts.
The BLS OES median for CNAs is roughly $38,200; hospital CNAs commonly earn $18–$26 an hour, and long-term care CNAs earn $16–$22 an hour, with shift differentials of $1.50–$4.00 an hour for evenings and nights and $2–$5 for weekends. Bilingual, memory-care, and hospice specialties push the top of the range. Ask what the facility offers for shift differential, weekend premium, and PTO accrual as three separate line items — that combination often moves an offer by $2,000–$4,000 a year.
Yes — and you should. Ratios are the single biggest signal of whether the unit will burn you out. A day-shift ratio of 1 CNA to 6–8 residents is typical in SNF; 1 to 10–15 on nights is common. Anything above that is a warning. Hospitals will name a med-surg ratio (often 1:8–1:12 for CNAs). If the answer is vague — 'it depends' — that's usually the answer.
