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
Tell me about your CT experience. What kinds of exams and protocols are you most comfortable running?
What they are checking: Whether their experience covers routine and specialized studies so they can work independently.
Tell me about a time you calmed a scared or confused patient so you could get the scan done.
What they are checking: Whether they combine compassion with skill, which the posting calls out directly.
This role has late shifts, every other weekend and a call rotation. How have you handled call before?
What they are checking: Whether they can reliably respond when called in, which keeps the scanner available for emergencies.
What would you do
A patient starts having a contrast reaction on the table. Walk me through your first steps.
What they are checking: Whether they stop the injection, call for help and know the reaction protocol without freezing.
A stroke alert comes in while you have a scheduled patient on the table. How do you handle it?
What they are checking: Prioritizing time-critical patients and communicating clearly with the waiting patient.
About the work
Before giving IV contrast, what do you check, and what would make you stop?
What they are checking: Checking kidney function, allergy history and IV placement, since contrast reactions and extravasation cause harm.
How do you keep radiation dose as low as possible while getting a diagnostic image?
What they are checking: Whether they truly apply ALARA with protocols and positioning, especially for children.
How do you decide whether an image is good enough or needs to be repeated?
What they are checking: Balancing image quality against extra radiation, rather than repeating scans without a good reason.
How do you confirm you have the right patient and the right exam before you scan?
What they are checking: Whether they always use two identifiers and verify orders, since a wrong scan exposes a patient for nothing.
How do you keep your Illinois license and ARRT certification current?
What they are checking: Whether they take continuing education seriously, since a lapse means they cannot work.
