by Esthetician interviews mix technique with retail. Spas and med spas want to know you can read a client's skin correctly, stay inside your license's scope, and sell the products on the back bar without sounding like a pitch.
The technical questions test whether you know when a treatment is contraindicated and when a chemical peel is outside what your license allows. The retail and client questions test whether people actually want to sit in your chair again.
Here are the 20 questions spas and med spas ask most, with sample answers specific enough to show real judgment.

How the interview usually works
- Application and license verification. Employers confirm your state esthetics license is active and check any additional certifications, like laser or dermaplaning training.
- Interview with a spa director, owner, or lead esthetician. Mixes background questions with scenario questions about client care and scope of practice.
- Skills demonstration or working interview. Many spas have candidates perform a mock facial or demonstrate a specific technique before making an offer.
- Reference check. Often includes calling a previous employer to confirm rebooking rates and retail performance, not just technical skill.
General and background questions
1. What inspired you to become an esthetician, and what services are you licensed to perform?
Why they ask: They want to hear a real reason alongside a clear, accurate statement of your scope, since spas need to know exactly what they can book you for.
How to answer: Give a specific reason and list your actual licensed services.
Sample answer: I started as a client getting monthly facials for cystic acne and got curious about why certain ingredients worked when others made it worse, which led me into a 600-hour esthetics program. I'm licensed for facials, chemical exfoliation with alpha and beta hydroxy acids, microdermabrasion, waxing, and lash and brow tinting. I'm not licensed for medical-grade peels or laser work, which I know some spas offer under a supervising physician.
2. What's your state license, and do you hold any additional certifications?
Why they ask: They're confirming your credentials are current and finding out if you have specialized training that expands what they can book you for.
How to answer: State your license status plainly and name any relevant additional certifications.
Sample answer: I've held my esthetics license in this state for 3 years and it's current through next spring. I also completed a separate 40-hour dermaplaning certification last year and a manufacturer training on LED light therapy devices, since I wanted to be able to offer both without needing extra supervision once I started at my last spa.
3. What services do you offer clients, and where do you draw the line on what's outside your scope?
Why they ask: A spa needs an esthetician who knows exactly where their license stops, since offering something outside scope creates real liability.
How to answer: Name your core services and give a concrete example of something you'd decline or refer out.
Sample answer: I offer facials, superficial chemical peels using glycolic and salicylic acid, extractions, waxing, and brow shaping. If a client asks for a TCA peel above 20% or anything that penetrates past the epidermis, I explain that's outside my license and refer them to the dermatologist our spa partners with. I had a client push back on that once, insisting her old esthetician did it, and I held the line since a licensing board complaint isn't worth it for either of us.
4. How do you stay current on new products, techniques, and skin care regulations?
Why they ask: Products and techniques change fast, and a vague answer about "reading a lot" doesn't show a real habit.
How to answer: Name specific resources and a recent example of something you learned and applied.
Sample answer: I follow continuing education requirements for my license renewal, which in my state means 12 hours every 2 years, and I try to take at least one hands-on course a year beyond the minimum. Last year I took a manufacturer training on a new enzyme peel line and started using it on clients with rosacea who couldn't tolerate our older AHA formula. I also follow updates from my state cosmetology board directly rather than relying on secondhand information from coworkers about what's allowed.
5. What do you believe are the most important qualities of a successful esthetician?
Why they ask: A generic answer about "loving beauty" doesn't show they understand what actually keeps clients rebooking.
How to answer: Name 1 or 2 specific qualities tied to real client outcomes.
Sample answer: Accurate skin reading matters more than almost anything else, since recommending the wrong treatment for someone's actual skin type or condition is how you lose a client for good. Close behind that is being honest even when it costs you a sale, like telling a client a treatment won't help their specific concern instead of booking it anyway. Clients notice that honesty and it's usually why they come back and refer friends.
Technical and role-specific questions
6. Walk me through your sanitation and disinfection process between clients.
Why they ask: Sanitation failures are the fastest way to lose a license and put clients at real risk.
How to answer: Describe your specific process: disinfectant type, contact time, and single-use items.
Sample answer: I clean visible debris off tools first, then disinfect metal implements in an EPA-registered hospital-grade disinfectant for the full contact time on the label, usually 10 minutes, not just a quick wipe. Anything that touches broken skin or blood, like a lancet, is single-use and goes straight into a sharps container. I change linens and wipe down the treatment bed, trolley, and any bottles I touched with gloved hands between every single client, no exceptions for a quick or simple service.
7. What's your process for screening a new client for contraindications before a treatment?
Why they ask: Skipping this step is how estheticians cause burns, reactions, or complications that could have been avoided with 2 minutes of questions.
How to answer: Describe your intake questions and what would make you modify or decline a treatment.
Sample answer: Every new client fills out an intake form covering medications, especially retinoids and isotretinoin, recent sun exposure, pregnancy, and any history of cold sores or skin conditions like rosacea or eczema. I follow up verbally too, since forms get filled out quickly and people forget things like a recent Botox appointment. If someone's on isotretinoin, I won't perform a chemical peel or aggressive extraction, since their skin barrier is compromised and the risk of a bad reaction is real, not theoretical.
8. Walk me through how you'd handle a client asking for a chemical peel stronger than what's allowed under your license.
Why they ask: This tests whether you'll hold a legal and safety line under direct client pressure.
How to answer: State the limit clearly and offer an alternative within your scope.
Sample answer: I'd explain specifically what I can offer, like a 30% glycolic peel, and why a stronger medium-depth peel needs to be done by a physician or nurse under medical supervision in my state. I'd offer to build a series of lighter peels over a few months instead, which can get meaningful results for a lot of concerns without the downtime or risk of a deeper peel. If she really wants the stronger option, I'd give her the name of the dermatology office we refer to rather than just saying no and leaving her without a next step.
9. How do you approach retail recommendations without being pushy?
Why they ask: Retail sales are a real part of spa revenue, and they want someone who sells through genuine fit, not pressure that drives clients away.
How to answer: Describe tying recommendations directly to what you observed during the treatment.
Sample answer: I only recommend something I specifically noticed during the facial, so it's tied to a real observation, not a general pitch. If I see a client's skin is dehydrated, not oily, I'll say that directly and suggest the hyaluronic serum we used during the treatment, explaining why it addressed what I saw. I don't push if they say no once. At my last job, that approach got me one of the higher retail attachment rates on the team, and I think it's because clients trusted the recommendation was actually about their skin.
10. Walk me through your consultation process for a new client's first facial.
Why they ask: A rushed or generic consultation leads to a treatment that doesn't match the client's actual skin or goals.
How to answer: Describe your intake, skin analysis, and how you set expectations.
Sample answer: I start with the intake form, then do a visual and tactile skin analysis under good lighting, checking for oil production, texture, and any active breakouts before I touch a single product. I ask what result they're hoping for, since a client might say "acne" but actually mean post-acne marks, which needs a different approach than active breakouts. I explain the treatment plan before I start, including anything that might cause temporary redness, so there are no surprises when they look in the mirror after.
11. What's your understanding of bloodborne pathogen precautions during extractions or waxing?
Why they ask: Both services carry a real risk of skin breaks, and OSHA-style precautions aren't optional.
How to answer: Name the specific precautions you take.
Sample answer: I wear gloves for every extraction and change them if they touch anything outside the treatment area. Any lancet or single-use tool that touches broken skin goes directly into a sharps container, never back on my tray. For waxing, if I nick skin with a stick or see any bleeding, I stop, apply pressure with a clean gauze, and use a fresh applicator and clean wax pot area before continuing, since double-dipping into shared wax after any skin break is a real cross-contamination risk.
12. How do you handle clients with different skin types, especially when it comes to laser or peel candidacy?
Why they ask: Darker skin tones carry higher risk for certain treatments, and a generic "I treat everyone the same" answer misses that.
How to answer: Reference skin type classification and a specific example of adjusting a treatment plan.
Sample answer: I take Fitzpatrick skin type into account for anything involving heat or aggressive exfoliation, since higher Fitzpatrick types carry a higher risk of post-inflammatory hyperpigmentation from treatments that would be low-risk on lighter skin. For a client with Fitzpatrick type 5 wanting a glycolic peel, I'd start at a lower percentage and shorter contact time than I would for type 2 skin, and watch closely for any sign of overreaction before increasing strength in later sessions.
Behavioral questions
13. Tell me about a time you dealt with a difficult client.
Why they ask: Client friction is routine in this job, and they want to see you handle it without losing your professionalism or the client.
How to answer: Describe the situation, what you did, and the outcome.
Sample answer: A client came in furious that her skin had broken out after a facial the week before, done by a different esthetician. Instead of getting defensive on my coworker's behalf, I looked at her chart, saw she'd had extractions on active cystic acne, which commonly causes a short breakout as things surface, and explained that clearly along with what I'd do differently this session to minimize it. She calmed down once she understood it was a known reaction, not a mistake, and rebooked before she left.
14. Tell me about a time a client was unhappy with their treatment result.
Why they ask: Managing a dissatisfied client well is often what determines whether they ever come back.
How to answer: Describe listening first, then the specific fix you offered.
Sample answer: A client felt her brow wax left one side noticeably higher than the other, and honestly, when I looked again, she had a point. I didn't argue with her perception. I apologized, fixed the shape right there at no charge, and made a note in her file about her natural brow asymmetry so the next esthetician wouldn't repeat the same imbalance. She's been a regular for over a year since.
15. Tell me about a time you upsold a product or service naturally, without pressure.
Why they ask: They want proof your retail approach actually works, not just a description of your philosophy.
How to answer: Give a real example with an outcome.
Sample answer: During a facial, I noticed a client's skin was reacting to sun exposure with visible redness she mentioned happened every summer. I pointed it out during the treatment and recommended a mineral SPF we carried, explaining specifically why a mineral formula would suit her reactive skin better than a chemical sunscreen. She bought it that day and has repurchased it every 2 months since, which became one of my more reliable recurring retail sales.
16. Tell me about a time you had to say no to a client's request.
Why they ask: Saying no while keeping the relationship intact is a real skill, and they want to see you've done it.
How to answer: Describe the request, why you declined, and how you kept the client.
Sample answer: A client wanted me to wax over an area with visible irritation from a new retinol she'd started using that week. I said no, explained that waxing over compromised skin barrier risks tearing or a bad reaction, and offered to reschedule for the following week once her skin calmed down. She was frustrated in the moment, but she came back for the rescheduled appointment and has trusted my judgment on timing ever since.
Situational questions
17. A client has a visible active cold sore and wants a lip wax. What do you do?
Why they ask: This is a direct contraindication with a real risk of spreading the virus, and they want to see you handle it without embarrassing the client.
How to answer: State that you'd decline the service and explain why, discreetly.
Sample answer: I'd decline the lip wax and explain quietly that waxing over an active cold sore can spread the virus to other areas of the face and worsen the outbreak itself. I'd offer to reschedule once it's healed, usually 7 to 10 days, and I wouldn't make a big deal of it in front of anyone else in the room. Most clients appreciate the honesty once it's framed as protecting their skin, not refusing to serve them.
18. Mid-facial, a client has a visible skin reaction to a product you applied. What do you do?
Why they ask: Reactions happen even with a good patch-test process, and they want an immediate, calm response.
How to answer: Describe stopping the treatment, removing the product, and assessing severity.
Sample answer: I'd stop immediately, remove the product with cool water or a gentle cleanser, and assess how severe the reaction looks, mild redness versus swelling or hives. For a mild reaction, I'd apply a calming, fragrance-free product and let her rest before continuing with something else, and I'd document exactly what caused it in her file. For anything that looks like a real allergic reaction, swelling near the eyes or difficulty breathing, I'd stop the service entirely and get her medical attention rather than try to treat it myself.
19. A client asks you to perform extractions on a client who's currently on isotretinoin. What do you do?
Why they ask: Isotretinoin significantly thins the skin barrier, and treating it like a normal appointment can cause real harm.
How to answer: State that you'd decline aggressive extraction and explain the medical reason.
Sample answer: I'd decline extractions and any chemical exfoliation for a client currently on isotretinoin, since the medication makes skin much more fragile and prone to tearing or scarring from manipulation that would be routine on unmedicated skin. I'd explain that clearly, since a lot of clients don't realize their skin is that vulnerable while on the medication, and offer a gentle, hydrating facial instead that supports their skin without the risk.
20. A regular client is 20 minutes late and your schedule is fully booked after them. What do you do?
Why they ask: Scheduling conflicts happen constantly, and they want to see you protect other clients' time without losing the late one.
How to answer: Describe offering a shortened service or rebooking rather than running the whole schedule late.
Sample answer: I'd offer her a shortened version of her usual service that fits in the remaining time, explaining honestly that I have a client booked right after her and can't run over. If a shortened service doesn't make sense for what she booked, like a full chemical peel that needs its full processing time, I'd offer to reschedule rather than rush a treatment that needs precise timing to be safe. I'd rather have an honest conversation about the time than let it cascade into every client that day running late.
Questions to ask the interviewer
- What products and brands do you carry, and is there training provided before I start recommending them?
- What's the typical client volume per day, and how much time is scheduled between appointments?
- Do you offer any services that require a license beyond standard esthetics, like laser or advanced peels, and is there a path to get certified for them here?
- How does retail commission work, and what's a realistic target for a new esthetician?
- Is there a supervising physician or dermatologist relationship for treatments outside my scope?
- What does the working interview or skills demonstration typically involve?
How to prepare
- Know your state's licensing scope cold, including exactly where superficial treatments end and medical-grade treatments begin.
- Review contraindications for common medications and conditions, like isotretinoin, recent Botox, and active cold sores, since these come up constantly in interviews and on the job.
- Prepare 2 or 3 specific client stories: a difficult client, an unhappy client, and a time you said no to a request.
- Practice describing your sanitation process out loud, step by step, since a vague answer here is a real red flag to spa owners.
- Bring your license and any additional certifications to the interview, since most spas verify this before extending an offer.
