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
This role starts in radiography and expects you to earn your CT credential within a year. How are you planning to get there while working nights?
What they are checking: Whether they have a real, workable plan for the CT credential instead of treating the deadline as someone else's problem.
Tell me about a time you had to position a patient who was in a lot of pain. How did you get a diagnostic image without hurting them?
What they are checking: Whether they balance image quality with patient comfort and adapt technique rather than forcing a standard position.
The posting mentions helping the department coordinator with projects and clinical leadership. Tell me about a time you took on work beyond your scans.
What they are checking: Whether they step up for department needs, which matters on a registry night shift with little oversight.
What would you do
You're the tech on a 7p to 7a shift at Walworth and you're asked to flex from X-ray to CT mid-shift. How do you handle the switch?
What they are checking: Whether they can change modalities calmly and safely when a small night crew has to cover everything.
You're about to give IV contrast and the patient mentions a past reaction that isn't in the chart. What do you do?
What they are checking: Whether they stop and escalate a contrast allergy instead of pushing ahead to stay on schedule.
An anxious patient refuses to hold still for a CT scan. How do you gain their cooperation?
What they are checking: Whether they can calm and instruct a scared patient so the exam succeeds on the first try.
About the work
Walk me through how you corroborate a patient's clinical history with the ordered procedure before you image them.
What they are checking: Whether they catch wrong or incomplete orders before exposure, since the radiologist depends on that history to read the study.
How do you start and maintain an IV on a patient with difficult veins at 3 a.m. when help is limited?
What they are checking: Whether they have practical IV skills and know when to stop sticking and call for help.
How do you keep aseptic technique during a contrast injection or other procedure that calls for it?
What they are checking: Whether infection prevention is a habit for them, not something they do only when someone is watching.
What would you check before you start a shift on equipment you haven't used in a few weeks?
What they are checking: Whether a PRN tech stays current on equipment and modality competencies between shifts.
