How to Run a Working Interview for a Dental Assistant

A résumé tells you where someone has been. A half-day in your operatory tells you whether they'll fit your team, your pace, and your patients. But only if you structure it — an unstructured working interview is just a stressful shift that leaves everybody guessing.

Why offices do this at all

Dental assisting is a role where a person can interview beautifully and still not work out — and where a quiet candidate who barely says a word can turn out to be the best hire you've made in years. What separates them isn't confidence in a chair across your desk. It's how they move in an operatory: whether they anticipate, whether they stay calm when the schedule slips, whether a nervous patient relaxes around them.

You cannot see that in a conversation. You can see it in about four hours.

Get these three things right before the day

Most working interviews go sideways for administrative reasons, not clinical ones. Handle these first.

1. Pay for the time.

If a candidate is performing work that benefits your practice, the safe and fair assumption is that the time is compensated. Agree on the rate and the hours in writing beforehand so nobody is surprised. Wage and hour rules are a legal question, not a dental one — if you're unsure how a working interview should be classified and paid in your state, ask your employment attorney or HR advisor rather than copying what the office down the road does. This article is general guidance, not legal advice.

2. Sort out patient consent and privacy.

You're bringing a non-employee into treatment areas where protected health information lives. Decide in advance how you'll handle patient notification, HIPAA paperwork, and any confidentiality agreement, and be straightforward with patients about who is in the room. Most patients are completely fine with it when they're simply told.

3. Know what they're actually allowed to do.

Scope of practice isn't a preference — it's regulated. What an unregistered assistant, a registered dental assistant, and a radiology-certified assistant may each perform in Texas is defined by the state, and it depends on the individual's current credentials. Verify the specifics at tsbde.texas.gov and confirm the candidate's own credentials before the day, not during it. When in doubt, keep them in a supporting role and evaluate the rest.

A structure that actually works (tap through it)

Here's a half-day shape you can reuse for every candidate. Running the same sequence each time is what makes the comparison fair — and what protects you from hiring on charm.

The five things worth watching for

Skill you can teach. These five are much harder to install in someone who doesn't already have them.

Anticipation. Do they watch the procedure and reach for the next thing, or wait to be asked every single time? This is the single best predictor of how they'll feel to work next to in six months.
Recovery. Everybody makes a mistake during a working interview — they're in a strange room with strange trays. What you're grading is what happens next: do they say something, fix it, and move on, or do they go quiet and hide it?
Patient presence. Watch the patient, not the candidate. Does the person in the chair get calmer or more tense when this assistant is nearby?
Sterilization discipline. Infection control habits are visible within an hour, and they tell you how someone was trained and whether they cut corners under time pressure.
Fit with your actual team. Ask your hygienist and your front desk what they thought. They will notice things the doctor won't, and they're the ones who have to work with this person daily.

One scorecard, every candidate

Write down the five things above, score each one 1–5 the same afternoon, and keep the sheets. It takes four minutes and it turns "I liked her" into something you can actually compare a week later when you've seen three people. It also keeps your process consistent — which matters if a hiring decision is ever questioned.

What not to do

Don't run it unstructured. "Just come hang out Thursday" produces a day where the candidate stands around and everybody's too busy to evaluate anything.

Don't use it as free labor. Beyond the fairness problem, word travels fast in a market this size. East Texas dental is a small world, and a reputation for stringing candidates through unpaid days will cost you the good ones.

Don't skip it because the candidate is new. A recent graduate with no office history is exactly who a working interview is most useful for — you're evaluating trained habits and temperament instead of a job list. New assistants who trained on real equipment usually show it in the first hour.

Don't decide alone. If your assistant and hygienist both hesitate, listen to that.

Before and after the working interview

A working interview is one stage, not the whole process. Ahead of it, a structured conversation narrows the field — we keep a list of interview questions worth asking dental assistant candidates, and a companion piece on what to look for in a new RDA hire. Afterward, the hire either sticks or doesn't largely on the strength of the first week — here's how we'd structure that.

And if you're hiring in the Longview, Kilgore, Henderson or Tyler area and would rather start from a shorter list, you can request a graduate from us directly. There's no fee — we'd simply rather our students land somewhere good, and you'd rather meet people who have already spent 12 weeks on real equipment. More on how that works on our hiring partners page.
