Lesson 3: Screening and the Working Interview

Here is an uncomfortable truth about interviews. Left unstructured, most of them measure warmth, confidence and conversational skill. Those matter in a dental office, genuinely. They are also the exact traits a candidate who interviews well and works poorly has in abundance, which is how practices end up saying "she was wonderful in the interview" about someone they let go in July.

The fix is not a harder interview. It is a repeatable one. Same questions, same order, for every candidate for the same role, scored against the definition you wrote in Lesson 1. That is the whole idea, and it is the single change that most improves hiring outcomes in a small practice.

This lesson covers the sequence: phone screen, structured interview, and the working interview, which is common in dentistry and carries more legal weight than most owners realize. For the deep reference version, including a long structured question bank and reference check script, see the Practice Guide chapter on hiring dental staff.

The phone screen: fifteen minutes, same questions

The phone screen exists to prevent a bad in person interview, and it costs a quarter of the time. Ask every candidate the same short set and take notes in the same format so the calls are comparable afterward.

A workable sequence: what interested you in this role, walk me through what a normal day looks like in your current job, why are you looking, the schedule is these days and hours and does that work for you consistently, the posted range is this and is that in line with what you are looking for, which licenses or permits do you hold and in which state, and what questions do you have for me.

That last one is not filler. A candidate who has no questions after twelve minutes is either not interested or not curious, and curiosity is one of the more reliable predictors of someone who will figure out your software without being walked through every screen. Pay attention to what they ask about. Questions about training and how the day runs are a good sign. Questions only about time off before anything else is discussed are not disqualifying, but they are information.

Structured interviews: ask about the past, not the hypothetical

Hypothetical questions ask what someone would do. People are good at inventing the right answer to those, because the right answer is usually obvious. Behavioral questions ask what someone did, and inventing a detailed, consistent past is much harder.

So: "Tell me about a time you noticed something had been missed, like a lab case that was not back or a patient who had not been confirmed. What did you do?" Then follow up until you have specifics. What happened next. Who else was involved. How did it turn out. What would you do differently.

Pick eight to twelve questions that cover the competencies on your one page, and use the same ones for every candidate for that role. A few areas worth covering in almost any dental hire:

• Reliability and ownership. A time they caught something that had been missed. A week with more work than time, and how they chose what came first. A mistake they made, how they found out, and what they did.
• Composure. The most chaotic day they have had in an office and what they did to keep it moving. A time a patient or coworker was rude and how they handled it in the moment and afterward.
• Coachability. Feedback that was hard to hear, and what changed as a result. Something they learned in the last year and how they learned it.
• Teamwork. A coworker they found difficult and what they actually did about it. What they do when their own work is done and someone else is behind.
• Role specific judgment. Walk me through your setup and assist for a crown prep. Walk me through what you do with a claim denied for missing information. Walk me through how you would fill a one hour opening tomorrow at ten.

Score each answer right after the interview, before you talk to anyone else about the candidate. Scoring after a group conversation is just recording whoever spoke most confidently in the debrief.

What to listen for, and what reveals nothing

Strong answers share a shape. They are specific, they include what the person actually did rather than what the team did, they acknowledge the messy part, and they end with a result. Weak answers stay general, drift into what should happen in principle, and quietly relocate every failure to someone else.

A few signals worth weighting:

• Ownership of a real mistake. "I have never really made a significant mistake" is not humility and it is not a great memory. It usually means either no reflection or no candor, and both are expensive in a clinical setting where noticing your own error early is the entire safety mechanism.
• Every previous coworker was the problem. One difficult former workplace is a fact of life. A pattern where the assistants were lazy, the front desk was hostile and the last three doctors were unreasonable is a pattern about the narrator.
• How they talk about patients. Listen for whether patients appear in their stories as people or as obstacles to the schedule.
• Whether they stay in their lane. A clinical candidate who answers "do I really need this crown?" by diagnosing for the doctor is telling you something about how they will handle scope.

And the questions that reveal nothing: what is your greatest weakness, where do you see yourself in five years, are you a team player, describe yourself in three words. These are rehearsed. They cost you interview minutes you could spend on a behavioral question that actually differentiates candidates. Cut them.

The working interview: useful, and not casual

Working interviews are common in dentistry for a good reason. An hour or two chairside tells you things a conversation never will: whether someone anticipates, whether they clean up behind themselves, whether the team relaxes or stiffens when they are in the room, whether they ask a question or guess.

Now for the part that gets practices in trouble. A working interview is not a neutral, informal favor. When a candidate does real work in your office, you have moved into territory governed by employment law, and the rules involved are federal, state, and sometimes local.

The obligations that owners most often underestimate:

• Pay. Wage and hour law generally treats work that an employer permits a person to perform as work that must be paid. Unpaid "trial days" and "shadow days" where the candidate actually does productive work are a recurring source of wage claims, and enforcement in dentistry is not hypothetical. Exactly how the pay must be handled, at what rate, and through what mechanism is governed by federal law plus your state's wage rules, which are sometimes stricter.
• Scope and credentials. A candidate may only perform duties they are legally permitted to perform in your state with the credentials they actually hold, and dental assisting and hygiene scope is state specific, as the team structure chapter explains. Verify licenses and permits before the day, not after. Radiography credentials in particular are registered and regulated differently from state to state, and our overview of x-ray registration and inspection is a reasonable orientation to how those regimes differ.
• Insurance. How workers' compensation and professional liability coverage treat a working interview participant is a question for your carriers, in advance, in writing.
• Patients. Patients should know who is in the room and why, and the person should be supervised throughout.
• Records. Whatever payroll and employment paperwork your jurisdiction requires for someone performing paid work applies here too.

Running the day so it tells you something

Assuming you have the structure squared away, design the day rather than improvising it. A planned two to four hours beats an unplanned full day.

Decide in advance what they will do and what you are watching for. Observe the morning huddle. Set up and break down a room. Assist on a couple of procedures. Process instruments. For a front office candidate, shadow first, then handle real calls with someone beside them. Pick tasks that surface the competencies from your one page, not just tasks that are convenient.

Then collect team input in a structured way rather than as a vibe. Ask the people who worked next to them three specific questions: did they follow instructions, did they pitch in without being asked, and would you want to work beside them every day. A vague "she seemed nice" from your lead assistant is not data. An answer to the third question is.

Watch for the quiet things. Did they wash their hands without being prompted. Did they ask before doing something they were unsure about, or guess. Did they notice the room was not turned. Did they still have energy at hour three. These are the behaviors that show up every day for the next four years, and they are almost impossible to read across a desk.

THE CHAIRSIDE TAKE

Ask every candidate the same behavioral questions in the same order and score them before you talk to anyone else, because an unstructured interview is mostly a personality test you did not intend to give. Use a working interview, they are genuinely revealing in a clinical setting, but build the structure with an employment attorney first, since the pay, insurance and scope questions around them are state specific and the downside of guessing is a wage claim rather than an awkward conversation. And when your lead assistant tells you the candidate did not wash their hands without being asked, believe her over the interview.
