How this list is built
The questions are editorial: they are written for this page, not copied from any employer, and no public source says which employer asks which question. What is sourced is the training. Federal rules in the Code of Federal Regulations (CFR) require nurse aide programs to cover communication and interpersonal skills, infection control, safety and emergency procedures, promoting residents' independence and respecting residents' rights (42 CFR § 483.152, eCFR). Those five areas shape the sections below, so each question tests something you were trained to do.
Each entry gives the answer in a few sentences, one line on why a question like it is useful to ask, and a place to read more. For the wider picture of healthcare hiring, start with the healthcare interviews guide. If you are weighing a move up the ladder, the nurse interview questions show the next role, and the x-ray technician interview questions show a technical imaging path. For a records-based route, see the outpatient coding interview questions.
The situation, task, action, result (STAR) method is a way to structure a story answer in four parts: situation, task, action and result. Use it for any "tell me about a time" question. Examples marked illustrative are invented scenarios, not reports of real events.
What a CNA is and how you qualify
Nursing assistants typically complete a state-approved education program and pass their state's competency exam (Bureau of Labor Statistics, August 2026). Nursing-home aide programs must run at least 75 clock hours, including at least 16 hours of supervised practical training (eCFR, 42 CFR § 483.152). That leaves 59 hours of other training if 75 is the total, and the practical share is 21.3% of the minimum.1
Activities of daily living are the basic self-care tasks, such as bathing, dressing, eating and moving about, that a patient may need help with. Demand is large: nursing assistants and orderlies together held 1,558,700 jobs in 2025, and the Bureau projects 3 percent growth from 2025 to 2035, an increase of 41,100 jobs (Bureau of Labor Statistics, 2026). That 41,100 is 2.6% of the 2025 total, consistent with the rounded 3 percent.1 Two corrections: there is no single national exam, because programs are state-approved and the exam is state-run, and the Bureau treats orderlies as a separate occupation.
Knowing it is half the job. Saying it is the other half.

Why do you want to be a CNA?
Give one true reason tied to the work itself, then one detail that shows you know the job. A CNA gives basic care and helps patients with activities of daily living, so name that daily care, such as helping someone eat, wash or move safely, instead of only saying you like helping people. Close with what you want next, such as staying on one unit or building toward nursing.
Why it is asked: a specific reason shows you understand the daily work. Read the full explanation: Bureau of Labor Statistics, nursing assistants.
Tell me about your training and certification.
State the facts plainly: your state, your program, how many hours it ran, and when you passed the state competency exam. Nursing assistants typically finish a state-approved program and pass that exam, so have both ready. Mention the supervised practical part, where you performed tasks on a real person under a nurse's direct watch. If you are still in training, say when you finish.
Why it is asked: it confirms you meet the entry route and can describe it clearly. Read the full explanation: eCFR, nurse aide training requirements.
What is your greatest weakness as a CNA?
Name a real, bounded weakness and show the habit you built around it. An illustrative answer: "I used to leave charting until the end of a shift and worry I would forget a reading. Now I write each reading down right after I take it." Avoid a fake weakness such as "I care too much", and end on what you changed.
Why it is asked: a strong answer shows self-awareness and a fix. Read the full explanation: healthcare interviews guide.
Residents' rights and communication
How do you communicate with a resident who is confused or cannot speak clearly?
Say you slow down, face the resident, use short sentences and watch for signs such as expression, gestures and discomfort. Explain each step before you do it. Check with the nurse or the care plan for known communication needs. Communication and interpersonal skills are one of the areas programs teach before any resident contact, so refer to that training and give one concrete example.
Why it is asked: a good answer shows patience and respect, not just talking louder. Read the full explanation: eCFR, training areas.
How do you protect a resident's privacy and dignity?
Describe actions: closing the door or curtain before personal care, covering the resident as much as possible, knocking and introducing yourself, and offering choices such as what to wear. Add that you share information about a resident only with the care team who need it. Respecting residents' rights is one of the five areas federal rules require programs to teach, and the nursing-home rule on resident rights states that a resident has a right to personal privacy and confidentiality of personal and medical records.
Why it is asked: personal care is intimate, so interviewers want to hear respect in your habits. Read the full explanation: eCFR, residents' rights training.
What would you do if a resident refuses a bath or a meal?
Stay calm, do not force it, and find out why: pain, cold, fear or tiredness are common reasons. Offer a choice, such as a later time or a partial wash, then tell the nurse. In STAR form (illustrative): the situation is a resident saying no to a morning bath; your task is to keep them clean and comfortable; you offered the bath after breakfast; the result was that they agreed and you reported the refusal.
Why it is asked: it shows whether you respect choice while still raising concerns. Read the full explanation: nurse interview questions.
How would you handle an upset family member?
Listen without interrupting, acknowledge the worry in plain words, and avoid arguing or giving medical explanations that belong to the nurse. Say what you can do now, such as getting the nurse, and then do it. Keep your tone steady and document what was said according to facility policy. Do not promise outcomes you cannot control.
Why it is asked: families are part of the job, and a calm answer shows you know your limits. Read the full explanation: healthcare interviews guide.
Infection control and safety
How do you prevent the spread of infection?
Say you wash or sanitize your hands before and after contact with each resident, wear gloves and other protective items when the task calls for them, keep clean and used items apart, and follow the facility's rules for isolation precautions. Infection control is one of the five areas nurse aide programs teach before any resident contact, so name what you learned and when you use it.
Why it is asked: infection control protects residents who are often frail. Read the full explanation: eCFR, training areas.
What would you do if a resident falls?
Stay with the resident and do not try to lift them unless your facility's policy says otherwise. Call the nurse right away, tell them what you saw and heard, and keep the resident calm and warm until help arrives. Afterwards, write down what happened as the facility requires. Safety and emergency procedures are part of the training every aide program must include.
Why it is asked: it tests whether you stay calm and escalate quickly. Read the full explanation: eCFR, safety and emergency procedures.
What would you do if a resident is choking?
Programs teach the Heimlich maneuver as part of safety and emergency procedures. Say you would recognize the signs, such as a resident who cannot speak or cough, call out for help and use the technique you were trained in, following facility policy. Afterwards you tell the nurse and document what happened. If you have not used it outside class, say so honestly and describe your practice.
Why it is asked: emergencies are rare but the response must be automatic. Read the full explanation: eCFR, training content.
How do you take and record vital signs?
Vital signs are the basic body measurements: temperature, pulse, breathing rate and blood pressure. Taking and recording vital signs is the first basic nursing skill listed in the federal training rule. A strong answer names what you measure, says you record each reading promptly and accurately, and reports anything outside the resident's normal range to the nurse instead of judging it yourself.
Why it is asked: accurate numbers drive nursing decisions. Read the full explanation: eCFR, basic nursing skills.
Independence and scope of practice
How do you help a resident stay independent?
Let the resident do what they can, even slowly: buttoning a shirt, washing their face, choosing an outfit. Help only with the parts they cannot do, and praise effort. Promoting residents' independence is one of the five areas of required training, so say that doing everything for someone can weaken their skills and confidence.
Why it is asked: it separates caring help from taking over. Read the full explanation: eCFR, training areas.
What would you do if asked to do a task you were not trained for?
Say you would not do it. Explain that you would tell the nurse you have not been trained, and ask who can do it or for training and supervision. Federal program rules aim to keep students from performing services they have not trained for, and what a CNA may do varies by state, so check your state's nurse aide registry or board.
Why it is asked: it tests whether you know your limits. Read the full explanation: eCFR, program requirements.
What would you do if you saw a coworker treat a resident roughly?
Make sure the resident is safe first. Then report what you saw to the nurse in charge or the person your facility names, with facts instead of opinions. Do not stay silent or only confront the coworker alone. Reporting duties are set by facility policy and by federal and state rules, so say you would follow them.
Why it is asked: it checks that you put residents' safety above comfort with coworkers. Read the full explanation: healthcare interviews guide.
Teamwork and pressure
How do you manage your time when several residents need you at once?
Say you sort by urgency first: safety needs and call lights for pain or falls come before routine tasks. Then you group tasks, keep residents informed ("I will be back in five minutes"), ask a teammate for help and tell the nurse if you cannot keep up. Avoid claiming you never feel rushed.
Why it is asked: a full assignment is normal, so interviewers listen for priorities. Read the full explanation: nurse interview questions.
Tell me about a time you worked as part of a team.
Use the STAR method with a true story from work, school, clinical training or volunteering. Give the situation and your task in two sentences, spend most of the time on what you did, such as covering a colleague's break or passing on a handover note, and end with the result. If you lack care experience, choose a story that shows reliability and communication.
Why it is asked: care happens in shifts and hand-offs, so teamwork matters. Read the full explanation: healthcare interviews guide.
How do you cope with the emotional side of the job, such as a resident's death?
Be honest and steady. Say that loss is part of long-term care, that you allow yourself to feel it, and that you rely on healthy habits and on talking with your team or supervisor. Show that you can keep caring for other residents that day. Avoid saying you feel nothing.
Why it is asked: it shows whether you can sustain the work without burning out. Read the full explanation: nurse interview questions.
What questions do you have for us?
Ask two or three real questions: the typical number of residents per aide on a shift, how new aides are oriented and supervised, and how the team handles hand-offs. Avoid asking about pay or time off first. A good question shows you are thinking about doing the job well.
Why it is asked: your questions show how seriously you take the role. Read the full explanation: healthcare interviews guide.
Follow-up questions
What are the common interview questions and answers for CNA roles?
The eighteen above cover the recurring themes: why you chose the work, your training, residents' rights and communication, infection control, emergencies, independence, scope and teamwork. Rehearse them out loud, because the wording matters less than a clear, honest example in your own voice.
How do I prepare for a CNA interview with no experience?
Use your training: the supervised practical hours, your clinical placement and the skills you practiced. Prepare two stories from any setting, such as volunteering or caring for a relative, with the STAR method. The healthcare interviews guide covers the general approach to role questions.
Do you need a degree to be a CNA?
No degree is the entry route. Nursing assistants typically complete a state-approved education program and pass their state's competency exam (Bureau of Labor Statistics).
Is a CNA the same as an orderly?
No. The Bureau of Labor Statistics lists nursing assistants and orderlies as separate occupations on a combined page, so check the job title and duties in each posting.
What other healthcare roles have similar interviews?
Nursing and administrative roles share the behavioral questions but differ in technical ones. See the nurse interview questions and the medical billing interview questions.
- A CNA gives basic care and helps with activities of daily living; entry is a state-approved program plus the state exam.
- Federal rules set at least 75 training hours with at least 16 supervised practical hours for nursing-home aide programs.
- Prepare for five themes: communication, infection control, safety, independence and residents' rights.
- Answer with concrete actions and a STAR story, and say plainly when something is beyond your training.
- Report concerns to the nurse; do not decide medical questions yourself.
