Questions to Ask in a CNA Interview
Questions for interviewing certified nursing assistant candidates, covering shift routines, personal care, reporting to the nurse, infection control, safe transfers, dementia care, and end-of-life work. Written for charge nurses, unit managers, and staffing coordinators who hire aides.
The questions
Open any question for the note
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 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 both can struggle if moved without support.
Walk me through how you start a shift. What do you check first?
Why ask it
Experienced aides describe a sequence: report from the outgoing shift, a quick look at each person, then who needs help first. Candidates who begin with their task list rather than laying eyes on people tend to miss overnight changes.
How do you introduce yourself to someone you are helping with bathing or toileting for the first time?
Why ask it
Listen for whether they speak to the person, explain what they are about to do, and wait for a response, including with residents who cannot answer. This is the single most revealing question about how someone treats people in their care.
Tell me about a resident who refused care. What did you do?
Why ask it
Good answers involve backing off, finding out what the refusal was about, trying later, and telling the nurse. Answers that involve talking someone into it, or completing care over an objection, describe a practice you will have to correct.
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
You are testing judgment about escalation. A candidate who names specifics is safer than one who says they report everything, which in practice means nothing gets flagged. Listen for a change in breathing, a fall, new confusion, a refusal of fluids, or skin that was intact yesterday.
What have you noticed about someone's condition that turned out to matter?
Why ask it
Aides see changes before anyone else because they see people undressed and up close. A concrete story shows they connect observation to action rather than waiting to be asked: less appetite for two days, a reddened heel, a resident who has gone quiet.
How do you keep someone covered and comfortable during personal care when there is a roommate in the room?
Why ask it
The practical answer mentions curtains, closed doors, keeping the person covered as they work, and not discussing care in the hallway. Candidates who have never thought about the roommate have not thought much about dignity either.
What is your routine for hand hygiene and gloves during a round of care?
Why ask it
Look for changing gloves between tasks on the same person and hand hygiene between rooms rather than a general statement about following protocol. Vague answers here often mean habits learned under time pressure rather than in training.
How do you transfer someone who can bear weight only partly, and when do you get a second person?
Why ask it
The answer should include checking the care plan, using the equipment the facility provides, and a clear threshold for asking for help. Anyone who describes lifting alone to save time is a risk to residents and to their own back.
Tell me about a shift when you were short staffed. What did you do differently?
Why ask it
Everyone has had these shifts, so the interesting part is triage: who they saw first, what they told the nurse, what they let slide. Answers claiming nothing slipped are usually less honest than answers that name what did.
How do you respond to someone with dementia who is asking to go home?
Why ask it
Skilled answers sit with the feeling and redirect gently, without arguing about the facts or making promises. Correcting the person repeatedly, or telling them a family member is coming when they are not, are both signs of untrained instinct.
What do you do when a family member is unhappy with the care their relative is getting?
Why ask it
You want to hear listening first, then what is within their role, then handing it to the nurse or manager rather than defending themselves or blaming the previous shift. How they describe the family tells you a good deal about their patience.
Have you disagreed with a nurse about someone's care? How did you raise it?
Why ask it
A candidate who has never raised a concern in years of work either has not been listened to or does not speak up. The useful answer describes going back with a specific observation rather than an argument in front of the resident.
What do you document, and what does your charting look like at the end of a shift?
Why ask it
Charting intake, output, care given, and refusals is what protects both the resident and the facility. Candidates who leave documentation until the last ten minutes of every shift, and say so, are telling you where errors will appear.
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.
How do you protect your back and your own health over a long stretch of shifts?
Why ask it
Injury is the main reason aides leave the work. Candidates who mention equipment, asking for help, and their own limits last longer than those who describe pushing through, and their answer also tells you whether previous employers made help available.
What do you do after a hard shift, and who do you talk to?
Why ask it
This is asked in place of a question about resilience, which invites a rehearsed answer. Naming a person, a routine, or a habit is a sign of someone who has found a way to keep doing the work after a resident dies.
What is outside your scope as a CNA, and what do you do if you are asked to do it anyway?
Why ask it
A clear answer names the boundaries in your state and a plan to decline and tell the nurse. Candidates who are hazy about scope, or who describe having given medications because the unit was busy, need that corrected before their first shift.
What certifications do you hold, and when do they renew?
Why ask it
Verify certification and registry status separately rather than relying on the answer, but the question surfaces lapses, out-of-state credentials, and pending renewals early, which is where onboarding usually stalls.
What would you like to know about this unit, our staffing, and how we support aides?
Why ask it
Candidates who ask about ratios, equipment, orientation length, and who covers breaks have done this work and are deciding whether to stay. No questions at all, in a job this demanding, often means they are applying everywhere and will leave the same way.

Practical guidance for the conversation itself
Structuring the interview
Ask for a past shift, not a hypothetical
Hypothetical questions produce textbook answers. Asking what happened on a particular shift, and then asking what they would do differently, separates candidates who have done the work from those who have studied it.
Walk the unit together
Ten minutes on the floor tells 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
Candidates who learn the real caseload after they start leave within weeks. Naming the ratio, the break coverage, and the hardest shift in the rotation costs you a few applicants and saves the turnover.
Verify credentials yourself
Check the state registry for certification status and any findings before an offer, and confirm renewal dates. Do this independently of what the candidate said, for every hire.
What strong answers have in common
- They speak about residents by describing what the person wanted, not only what the task required.
- They escalate with specifics: what changed, when, compared with what.
- They name their scope of practice without being prompted.
- They describe asking for help with transfers rather than managing alone.
- They can say what they got wrong once and what they changed.
Answers that warrant a follow-up question
Care completed over a refusal
A resident has the right to decline. If a candidate describes finishing a bath despite 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 handovers really are poor. Repeated blame across several stories usually predicts the same pattern on your unit.
Tasks outside scope described casually
Giving medication, adjusting oxygen, or interpreting a symptom for a family member are not aide duties. Casual mention suggests a previous employer let boundaries slip.
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.
- 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, since this is the main reason new aides stay or go.
- Judge attitude toward personal care and toward being corrected, both of which are harder to teach than technique.
