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 a patient had a reaction to contrast. What did you see, and what did you do first?
recognition of contrast reaction symptoms and whether they escalate to the radiologist appropriately and quickly
You're PRN, so you might walk into a shift on a unit or protocol you haven't touched in a while. How do you get yourself oriented fast without slowing the department down?
adaptability and self-sufficiency, which matters a lot for a per diem hire who won't get the same ramp-up as staff
Tell me about a time you had to call a code blue or recognized a patient was crashing during a scan. What happened?
clinical vigilance and comfort responding to emergencies while operating equipment
How do you handle a patient who is anxious, confused, or combative and needs to stay still for the scan?
bedside manner and de-escalation skill with the range of patients a Level 1 trauma center sees
Technical
How do you decide on kVp, mA, and pitch settings for a CT abdomen versus a CT chest, and how do you think about dose while you're doing it?
real technical fluency with CT protocols and ALARA dose awareness, not just button-pushing
Tell me about starting an IV on a patient with difficult access. What's your approach before you call for help?
actual IV skill level and judgment about when to escalate versus keep trying
Walk me through your daily QA checks on the CT scanner. What are you actually looking for?
whether they understand equipment quality assurance beyond just running a checklist
What's your experience with post-processing and reconstructions, and can you tell me about a study where the initial images weren't good enough and you had to redo something?
hands-on familiarity with reconstruction workflow and honesty about troubleshooting imperfect scans
Situational
Walk me through how you scan a trauma patient who comes in unstable, from the moment they hit your table to when the radiologist gets images.
whether the candidate can handle level 1 trauma pace and prioritize speed without sacrificing image quality or safety
Say a physician orders a contrast study on a patient whose creatinine just came back high. What do you do?
understanding of renal risk with contrast and whether they know when to hold and call rather than proceed
A patient arrives for a scan and you can't get a clear history, or the order doesn't match what you're seeing. How do you handle it?
attention to documentation accuracy and willingness to stop and verify rather than proceed on assumption
You get called in on short notice for a PRN shift and the department is already behind. What's going through your head as you walk in?
whether the flexibility and short-notice demands of a PRN role are something they've actually thought through, not just agreed to on paper
