Questions to Ask a CNA Candidate in an Interview
Questions to ask a CNA candidate in an interview, for the charge nurses, unit managers and staffing coordinators who hire nursing assistants. The 53 questions are in five groups: background, daily care, judgment, people, and stamina and fit. The standard ones are here (tell me about yourself, why they became a CNA, a resident who refused care, a shift that ran short) beside practical ones on reporting, scope, dignity and safe transfers, which separate a careful aide from one who simply interviews well. Each has a note on what a strong or weak answer sounds like and what to ask next. This is the interviewer's side of the table; a candidate can read it as a fair picture of what a CNA interview asks.

The questions
Each question, and why to ask it
Background
Tell me about yourself. What should I know that is not on your application?
Why ask it
They will have rehearsed this one, and that is its use: two easy minutes while the nerves settle. Notice what they lead with, whether it is six years on a memory care hall, a parent they nursed at home or nursing prerequisites at night. If they mention children, health or anything else personal, let it pass without a follow-up and steer back to the work.
Why did you become a CNA, and what has kept you in the work?
Why ask it
Nearly everyone says they like helping people, so ask for the moment it started. A grandmother they looked after, a resident from clinicals, or needing steady work that turned into something more are all real answers. The second half matters most with experienced aides, because the reasons people stay are the ones your unit has to keep supplying.
What kind of setting have you worked in, and how many residents or patients were you responsible for on a shift?
Why ask it
The ratio tells you what pace the candidate is used to. Someone who carried eight residents on days in a skilled nursing facility has a different working rhythm from someone who spent a year one-to-one in home care, and either can struggle if moved without support. Ask which shift it was, since the same hall is a different job at night.
Which part of the job are you best at, and which part do you still find hard?
Why ask it
This is the strengths and weaknesses question with the job put back into it. An aide who says showers run long, or that charting is where they fall behind, has told you what to cover in orientation. A weakness that is really a boast, such as caring too much, tells you only that they prepared.
Why do you want to work at this facility, and on this unit?
Why ask it
A candidate who knows whether you run rehab, long-term care or memory care has at least read the posting. A shorter drive, day shifts or a friend on staff are honest reasons and easy to plan around. If the unit they picture is not the unit you have, correct it now instead of in week two.
Why are you leaving your current job, or why did you leave the last one?
Why ask it
Staffing, pay and a manager who did not listen are the usual reasons, and none of them counts against anyone. Pay attention to how they speak about the residents they left behind. If their complaint is also true of your building, say so before they find out for themselves.
What would the last nurse you worked under say about you?
Why ask it
It brings the reference check into the room. A real answer sounds like something a nurse would say: her rooms were done before breakfast, he needed reminding to chart. Follow it by asking whether you may call that nurse, and watch how quickly the yes comes.
Why should we hire you over another aide with the same certificate?
Why ask it
Most candidates dread this one, so ask it warmly and give them a moment. The answers worth having are small and checkable: two years without a call-out, the aide a night nurse asked for by name, steady hands with a mechanical lift. If all you get is 'I am a hard worker', ask what a coworker would have seen that showed it.
What certifications do you hold, and when do they renew?
Why ask it
Ask it, then check the registry yourself whatever the answer. Its use is in what comes up early: a certificate from another state that has not been transferred, a renewal due next month, a CPR card that lapsed. Requirements differ by state and employer, so say which ones you need in hand before a first shift.
Which shifts, weekends and holidays can you reliably work?
Why ask it
Settle this before the offer, not when the first schedule goes up. Ask what they can work and leave the why alone: the reason behind a limit is often something an employer should not be asking about, and your HR lead can tell you where that line sits where you are. Then tell them your real weekend and holiday rotation.
If you are newly certified, what did your clinical hours involve, and what surprised you about the work?
Why ask it
For a new aide this stands in for a work history. How many residents they helped with, what care they gave with their own hands, and who was watching are the facts to get. The surprise is usually the smell, the pace or how attached they became, and each of those points to a different kind of orientation.
Daily care
Walk me through how you start a shift. What do you check first?
Why ask it
A practiced answer is a sequence: report from the aide going off, eyes on every resident, then whoever is wet, hungry or trying to get up. Stop them there and ask what they look at on that first walk down the hall. Breathing, color and whether the bed is as low as it should be are the details of someone who has done it.
How do you introduce yourself to someone you are helping with bathing or toileting for the first time?
Why ask it
The order matters more than the words: knock, use the person's name, give your own, say what you are there to do, then wait. Ask what changes when the resident cannot answer. An aide who still explains each step to someone who gives nothing back has understood the job.
How do you keep someone covered and comfortable during personal care when there is a roommate in the room?
Why ask it
Curtain pulled all the way, door shut, a bath blanket over whatever is not being washed. Then the parts people forget: the roommate's visitor in the next chair, and what gets said aloud about a brief or a bowel movement with someone lying six feet away. If the roommate has never crossed their mind, ask how they would want it done for their own mother.
What is your routine for hand hygiene and gloves during a round of care?
Why ask it
'I follow protocol' is not an answer, so have them narrate one resident from the doorway in. The detail to expect, measured against your own policy, runs something like this: hands cleaned on the way in, gloves changed after perineal care and before touching the clean brief or the bed rail, hands cleaned again on the way out. The habit to probe is gloves worn in place of washing.
What changes about your routine when a resident is on isolation precautions?
Why ask it
The first thing should be reading the sign on the door before going in, then gown and gloves on and off in the right order and equipment that stays in the room. The better candidates add something of their own: a person on precautions sees fewer faces all day, so they make a point of not rushing out.
How do you transfer someone who can bear weight only partly, and when do you get a second person?
Why ask it
Three things belong in the answer: the care plan checked for how this person transfers, the gait belt or lift it calls for, and a stated point at which they stop and fetch someone. Then ask about the day no second person was free. 'I waited and told the nurse' is what you want, and 'I just did it myself' is how injury reports begin.
A resident on your hall is unsteady and keeps getting up alone. What do you do?
Why ask it
Be wary of any fix that amounts to keeping the person where they cannot get up. That can count as a restraint, and restraints are not an aide's decision to make. The practical answers are offering the toilet on a schedule, the call light and walker where a hand can find them, the bed at its lowest, shoes that grip, and looking in more often.
How do you look after the skin of someone who cannot turn themselves?
Why ask it
Ask where on the body they look, because people who have done this for a while say tailbone, hips and heels before you finish the question. The rest of a sound answer is turning on the schedule in the care plan, heels floated off the mattress, a dry and smooth sheet, and redness reported to the nurse the same day.
How do you help someone at a meal who eats slowly or has trouble swallowing?
Why ask it
Picture the answer: the aide sitting down at eye level, the resident upright, small bites, no hurry because the trays are due back. Checking the diet and drink texture against the care plan belongs in there too, and coughing at meals should reach the nurse. An aide who alters a texture on their own judgment has left their role.
How do you take a set of vital signs, and what makes you take a reading again?
Why ask it
Anyone certified can list the measurements, so the second half does the work. You are hoping for the aide who rechecks a blood pressure that looks wrong, counts breathing without announcing it, and carries an odd number to the nurse instead of writing it down and moving on. Which readings aides take differs by employer, so say how it runs on your unit.
How do you help someone keep doing things for themselves when it would be quicker to do it for them?
Why ask it
Handing over the washcloth, laying out two shirts to choose from, waiting while someone does up their own buttons. The aide who does everything for everyone is fast and well liked, and residents lose ability under that kindness. Ask what gives when the clock is against them, because that is when the habit is tested.
What do you chart, and when in the shift do you get it done?
Why ask it
Meals, fluids, bowel movements, care given and care refused are the usual list, though what aides chart differs by employer. The timing is the telling half, because charting from memory in the last ten minutes is how a refused shower gets recorded as given. Ask whether they have used paper, a wall kiosk or a tablet, and say which you run.
Judgment
How do you decide what to report to the nurse right away and what can wait until the end of the shift?
Why ask it
'I report everything' sounds safe and tells you nothing, so ask for an example of each kind. Trouble breathing, a fall, chest pain or sudden confusion goes to the nurse at once; a poor lunch or a reddened heel still gets reported, before the shift ends. The aide to worry about is the one who sat on something because the nurse looked busy.
What have you noticed about someone's condition that turned out to matter?
Why ask it
Aides see people undressed and up close, so they are often the first to spot a change. You want a story with an ending: half a breakfast left two days running, a new bruise, a talkative resident gone quiet, and then whom they told and what came of it. If nothing comes to mind, ask what would make them look twice at someone they bathe every day.
Tell me about a resident who refused care. What did you do?
Why ask it
The story usually turns on a reason: the water was cold last time, the aide was a stranger, it was the hour her husband used to visit. Stopping, finding that reason, coming back later or sending a different aide, and telling the nurse make up the whole of a good answer. When the story ends with the shower happening anyway, ask how.
What is outside your scope as a CNA, and what do you do if you are asked to do it anyway?
Why ask it
Scope differs by state and by any extra certification, so listen for limits that match yours and correct them where they do not. The second half is harder, because the person asking is usually a nurse in a hurry. Something like 'I am not allowed to do that, but I can get the vitals for you' shows they can refuse without a standoff.
You walk into a room and find a resident on the floor. What do you do, in order?
Why ask it
The order is the answer. Stay with the person, call for the nurse, do not move them until they have been assessed, then report what you saw and chart it the way your policy asks. The instinct to get someone back into bed before anyone knows is the one to listen for, and it deserves a follow-up if you hear it.
Three call lights come on while you are halfway through giving a shower. What do you do?
Why ask it
No answer is perfect, which is why it is worth asking. Safety sorts most of it: the person in the shower cannot be left, and the resident who climbs out of bed outranks the one who wants the channel changed. What separates candidates is whether they call a teammate or the nurse, or try to be in three rooms at once.
What do you do when the care plan says one thing and what you see in front of you says another?
Why ask it
Care plans go stale. A resident listed as a one-person assist can no longer stand, or a diet order was never updated after a hospital stay. The answer to hope for is the safer course today and a word to the nurse so the plan gets changed, not a quiet workaround that the next aide knows nothing about.
Have you been on shift during an emergency, such as choking, a seizure or someone found unresponsive? What was your part?
Why ask it
You are checking that they know the aide's part: call for help, stay, do what they are trained and permitted to do, and give the nurse a clear account afterwards. A candidate who has never faced one can answer as a what-if. Either way, ask whether their CPR card is current if your employer requires one.
What would you do if you saw a coworker being rough with a resident, or speaking to one in a way that frightened them?
Why ask it
Only one answer is acceptable: make sure the resident is safe and report it straight away to the nurse or whoever your policy names. Aides are generally required to report suspected abuse, though to whom and how fast depends on your state and employer, so finish by explaining how it works in your building. Reluctance to get a colleague in trouble is the thing to explore.
How do you keep residents' information private, on the floor and on your phone?
Why ask it
Everyone has sat through the privacy training, so ask about the places it slips: talk in the elevator, an assignment sheet left in a pocket, a break-room selfie with a resident in the background. A candidate who says they never post about work has thought it through. Puzzlement at the phone half of the question is your cue to explain your policy.
Tell me about a mistake you made at work. How did it come to light?
Why ask it
Who reported it matters more than what it was. The aide who went to the nurse and said the bed alarm was left off is the one you can trust on nights. A spotless record should worry you more than a candid story, and if reporting an error does not cost people their jobs on your unit, say that out loud.
People
How do you respond to someone with dementia who is asking to go home?
Why ask it
Going home usually stands for something: a mother, a kitchen, a job to get to. Aides who are good at this ask about the house or walk with the person for a while, and do not argue that this is home now. Facilities differ on how far a comforting untruth may go, so say where yours stands on telling a resident that her husband is on his way.
Tell me about a time a resident hit, grabbed or swore at you during care. What did you do in the moment?
Why ask it
Listen to the tone as much as the steps. An aide who took it personally tells the story as an insult, and one who has learned the work tells you what the resident was frightened of. The steps themselves are stepping back, giving the person room, trying again later or with a different face, and telling the nurse.
How do you talk with a resident who is hard of hearing, cannot speak, or does not share your language?
Why ask it
Speaking louder is not a method. Facing the person, checking that hearing aids are in and working, short sentences, a whiteboard or picture cards, and patience are. For a language gap, ask what they would do beyond gestures, and tell them what interpreting your facility provides.
Tell me about a resident you got to know well. What did you learn about them that was not in the chart?
Why ask it
Aides who see the person can tell you that she takes her coffee lukewarm or that he laid bricks for forty years and hates being lifted. It is a gentle question with a hard edge, since a candidate who can only list diagnoses has been working on tasks. A new aide can answer from clinicals or from caring for a relative.
When did you last do more for a resident than your assignment asked?
Why ask it
This is the above-and-beyond question, and the best answers are small: ten minutes spent setting a resident's hair before her daughter came, the radio station a man had listened to for years found again. Ask whether the nurse knew. Extra kindness that goes around the care plan, such as a snack for someone on a restricted diet, is a different story and needs a follow-up.
What do you do when a family member is unhappy with the care their relative is getting?
Why ask it
The complaint is usually specific: Dad still in pajamas at eleven, the hearing aids left in a drawer. A good answer hears it out, fixes what an aide can fix on the spot, and takes the rest to the nurse without arguing or blaming the night shift. Note the word they use for the family, because 'demanding' and 'worried' can describe the same daughter.
Have you disagreed with a nurse about someone's care? How did you raise it?
Why ask it
Pay attention to what they brought with them: 'she was a one-person transfer on Monday and her knees buckled twice today' gets a nurse's attention where 'I don't think that's right' does not. Where it was said counts too, since the hallway is fine and the bedside is not. Years on the floor with no such story deserve a gentle second ask.
What do you do when another aide on your hall is not pulling their weight?
Why ask it
Every unit has had this, so a candidate with no story is being polite. Good answers go to the coworker first, and to the charge nurse once residents are going without. Covering for someone in silence until resentment sets in, and airing it at the nurses' station, are both worth a second question.
What do you tell the aide coming on after you, and what do you want to be told when you arrive?
Why ask it
A real handoff is specific: who had a bad night, who has not eaten, who is on the commode right now, whose daughter left upset. Candidates who can reel off that kind of list have worked on halls where report mattered. If your shifts overlap by five minutes, be honest about how much report there is time for.
Have you cared for someone who was dying? What did you do for the family?
Why ask it
Keep this part of the interview quiet and unhurried. Answers grounded in small practical acts indicate real experience: mouth care, repositioning, dimming the room, offering a chair and a glass of water to a daughter who has not slept. Some candidates will not have had this work yet, and saying so plainly is a fair answer.
Stamina and fit
Tell me about a shift when you were short staffed. What did you do differently?
Why ask it
The telling detail is what they chose to drop. Moving showers to the next day and saying so at report is triage; quietly skipping turns and fluids is not. An account in which nothing slipped is harder to believe than one that names what did, and this is a fair moment to say how often your own unit runs short.
What do you do in the middle of a shift when you can feel your patience running out?
Why ask it
Anyone who has worked a hall knows the moment, and the honest candidates admit it. Handing a resident to a teammate for ten minutes, stepping off the floor for a glass of water, or telling the nurse they need a minute all stop it landing on whoever puts a light on next. 'That never happens to me' is the reply to doubt.
How do you protect your back and your own health over a long stretch of shifts?
Why ask it
Years of lifting and repositioning wear aides down, so this is really a question about whether they will still be doing the job. Using the lift even when it takes longer, raising the bed before a brief change and waiting for a second person are the habits to hear. If they describe pushing through because no help ever came, you have learned about their last employer as much as about them.
What do you do after a hard shift, and who do you talk to?
Why ask it
It stands in for the resilience question, which invites a rehearsed answer. A sister they call from the parking lot, a walk before going indoors, a rule about not picking up extra the day after a resident dies: anything that specific means they have a way of putting the work down. Take what they offer and do not dig further.
When have you been asked to stay over or pick up a shift, and how do you decide when to say no?
Why ask it
You need to know whether you can ask, and they need to hear that they are allowed to refuse. An aide who never says no tends to leave all at once, while one who will do a double now and then but not back to back is giving you something you can schedule around. Be straight about how often you mandate overtime.
When were you last corrected on the floor, and what did you change?
Why ask it
Correction is constant in this job and comes from nurses, surveyors, families and residents alike. A candidate who can repeat what they were told and show what they did differently will take orientation well. Never having been corrected means either nobody was supervising or the story is being left out.
Where do you want to be in a few years: still at the bedside, in nursing school, or somewhere else?
Why ask it
Nursing school is a good answer, and so is wanting to stay an aide, which deserves more respect than it usually gets. If they plan to study, talk now about class schedules and any tuition help you offer. A unit that knows about the plan can build a schedule around it, and one that finds out late loses the aide.
What do you need from a charge nurse and a unit to do this job well?
Why ask it
It turns the interview around a little before the usual closing question. Lifts that work, a nurse who comes when called, and a fair split of the heaviest residents are the common requests. If one of them is something you cannot provide, this is the moment to say it.
What would you like to know about this unit, our staffing, and how we support aides?
Why ask it
Leave real time for this and answer with numbers. Ratios by shift, who covers breaks, how long orientation runs and what happens when someone calls out are the questions of someone choosing a job, and pay is a fair one too. If they have none, offer those answers anyway, since a newly certified aide may not yet know what to ask.
Interviewing nursing assistants
Practical guidance for the conversation itself
Structuring the interview
Pick a dozen and ask everyone the same ones
Nobody gets through the whole list in one sitting. Choose two or three from each group, put that same core set to every candidate for the post, and keep the rest for follow-ups. Answers to the same question are the only ones you can fairly compare.
Mix the standard questions with the scenarios
The familiar openers, such as tell me about yourself and why they became a CNA, settle a nervous candidate and fill in the background. The scenarios, such as a resident on the floor, three call lights at once or a care plan that no longer fits, show how they think on a hall. An interview made only of the first kind favors good talkers.
Ask experienced aides for a real shift
A what-if tends to get the textbook answer. Where the candidate has experience, ask what happened on a particular shift and then what they would do differently now. Keep the what-ifs for new aides and for emergencies they may never have met.
Walk the unit together
Where your policy allows a visitor on the floor, ten minutes there can tell you more than another twenty in an office. Watch whether they greet residents, whether they notice a call light, and whether they step aside for a wheelchair without being asked.
Be honest about the ratio
An aide who learns the real caseload on the first shift has a reason to keep looking. Naming the ratio, the break coverage and the hardest shift in the rotation may cost you an applicant or two, and the ones who accept know what they agreed to.
Verify credentials yourself
Check the state registry for certification status and any findings before an offer, and confirm renewal dates. Do it for every hire, independently of what the candidate said. What else has to be checked before a start date depends on your state and employer.
Ask about availability, not the reasons behind it
Shifts, weekends and overtime are fair subjects. Family, health, age, religion and similar matters generally are not, and the rules differ by country and state. If you are unsure whether a question is allowed, check with whoever handles HR before the interview, not after it.
What strong answers have in common
- They talk about what the resident wanted, not only what the task required.
- They escalate with specifics: what changed, when, compared with what.
- They name the limits of their role without being prompted.
- They describe waiting for a second person or the lift, not managing a transfer alone.
- They can tell you about a mistake they reported themselves and what they do differently now.
- They do not hesitate over reporting rough handling by someone else.
- There is a nurse in their stories: someone they told, and a point at which they told them.
Answers that warrant a follow-up question
Care completed over a refusal
Declining care is the resident's decision. If a candidate describes finishing a bath despite an objection, ask what they would do now, and treat the answer as a training question rather than an automatic no.
Blaming the previous shift
Some handoffs really are poor, and one such story means little. Blame that turns up in three different stories is likely to turn up on your unit too.
Tasks outside scope described casually
Scope varies by state and by extra certification, but giving medication, adjusting oxygen or explaining a symptom to a family member is outside an aide's role in most places. A casual mention suggests a previous employer let the boundary slip, so ask who told them to do it.
Handling everything alone
A candidate who dealt with the fall, the angry son and the short shift single-handed sounds capable. Ask at what point the nurse heard about each one. 'Straight away' is the answer you are hiring for.
No questions about staffing
Not always a problem for a newly certified aide, but from an experienced candidate it can mean they have stopped expecting an honest answer.
Interviewing someone newly certified
- Ask about clinical placement in detail: how many residents, what care they gave, who supervised.
- Turn the experience questions into what-ifs: what they would do if a resident refused a bath, or if they walked in and found someone on the floor.
- Ask what part of training they found hardest, which is usually more informative than asking what they enjoyed.
- Say plainly how long orientation lasts and who will precept them. A new aide weighing two offers will want to know, and deserves a true answer.
- Judge attitude toward personal care and toward being corrected, both of which are harder to teach than technique.
If you are the one being interviewed
- Have one real story ready for each of the usual scenarios: a refusal, a fall, a short shift, a mistake and an unhappy family member.
- Answer the fall and emergency questions in the order you would act. The sequence is what the interviewer is listening for.
- Say when you told the nurse. Most of the scenario questions are checking whether you report and how soon.
- If you are newly certified, say so and answer from clinicals. A plain 'I have not had that yet, but here is what I would do' is a good answer.
- Bring your own questions about ratios, lifts, orientation and who covers breaks.
