Likely interview questions for this role

Written from this job description, not a generic list. Each one notes what the interviewer is really checking.

Behavioral

Tell me about a time you noticed something off with a patient during treatment, maybe a symptom or a change in how they looked, and you had to decide whether to stop and call the physician.

clinical judgment and willingness to halt treatment when something seems wrong rather than push through

Tell me about a time a patient was frightened or in distress on the treatment table and you had to keep things moving on schedule while still calming them down.

ability to balance patient emotional needs against a tightly booked day shift schedule

Tell me about a time you caught a charting or documentation error, maybe in IMPAC or a paper chart, before it caused a problem downstream.

attention to detail in documentation that affects billing and continuity of care

Describe a time you had to give a physician feedback or a recommendation about a technical limitation, maybe equipment or patient positioning, that affected how a procedure could be done.

confidence and clarity communicating with physicians as a clinical peer rather than staying silent

Technical

Walk me through how you position and immobilize a patient for a treatment site like head and neck, and how you confirm the setup matches the prescription before you turn on the beam.

whether the candidate follows a rigorous, repeatable verification process before delivering radiation

How do you calculate treatment units from a prescription, and what do you do when your calculation doesn't match what the planning system shows?

technical competence with dosimetry math and comfort catching and resolving discrepancies rather than assuming the machine is right

What's your experience with CT simulation, and have you worked with brachytherapy or stereotactic radiosurgery setups?

actual hands-on breadth across the specific treatment modalities this department runs

How do you keep audio and visual contact with a patient during treatment, and what would make you interrupt a beam-on to check on them?

internalized safety habits versus rote compliance language

How do you personally track your radiation exposure, and what would you do if your dosimeter badge reading came back higher than expected?

seriousness about personal and staff radiation safety, not just patient safety

Situational

Say you're doing your daily equipment output checks on the linear accelerator and you get a reading that's borderline, not clearly bad but not clean either. What do you do?

judgment around equipment safety thresholds and whether they escalate versus treat patients on questionable equipment

A student is in your clinic and about to set up a patient in a way you think is slightly off. How do you handle that in the moment?

teaching ability and how they correct others without undermining confidence or safety

You notice a patient's weekly weight has dropped noticeably. Walk me through what you do next.

whether they know the actual clinical protocol for escalating nutritional or status changes to the care team

This role treats a wide age range, from kids to elderly patients. How do you adjust your approach when treating a young child versus an older adult who may be confused or fragile?

awareness of developmental and age-specific care needs mentioned explicitly in the posting
