Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
A patient on their fifth week of treatment is exhausted and tearful. How do you support them?
What they are checking: Whether they offer real emotional support while recognizing side effects that the care team should know about.
Tell me about a time you caught an error before it reached a patient.
What they are checking: Whether they have the attention to detail and willingness to speak up that radiation safety depends on.
What would you do
During the morning warm-up, a machine check comes back outside tolerance. What do you do?
What they are checking: Whether they will stop and escalate to physics rather than treat patients on equipment that may be off.
You're casual on-call across La Crosse and Tomah. How will you stay current on two sites' equipment and routines?
What they are checking: Whether they will keep their skills fresh and know each location's setup despite working less often.
How do you organize the daily treatment and simulation schedule with other therapists and the department secretary?
What they are checking: Whether they can coordinate a schedule that keeps patients moving and the department running smoothly.
A patient says something about a new symptom you think the doctor should hear about before treatment. What do you do?

About the work
Walk me through how you set up a patient for treatment and confirm you're delivering the right dose to the right spot.
What they are checking: Whether they follow strict patient ID, positioning and verification steps, since errors in radiation can cause lasting harm.
You perform beam-on time or monitor unit calculations that get reviewed by the oncologist and physicist. How do you double-check your own work before it goes to review?
What they are checking: Whether they take ownership of accuracy instead of relying on the review to catch their mistakes.
Tell me about your experience with simulation. What do you do to make sure the setup can be repeated every day?
What they are checking: Whether they understand that good simulation and immobilization make every later treatment accurate.
What radiation safety practices do you follow to protect yourself, coworkers and patients?
What they are checking: Whether they know and follow ALARA and room safety habits as second nature.
