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
The posting asks people without a CT credential to get it within 12 months of hire. Where are you in that process?
What they are checking: Whether they have a realistic plan to meet a clear requirement of the job in the stated time.
Tell me about a time you worked with a patient who was claustrophobic, confused or in a lot of pain. How did you get the scan done?
What they are checking: Patient care skills that get a usable scan without forcing or rushing a frightened or hurting person.
What would you do
As a PRN float, you could be called in any time, day or night. How do you get up to speed fast on a shift?
What they are checking: Adapting quickly to staffing, scanner and protocol differences, which a float technologist faces every time.
An ED trauma, an inpatient with a scheduled biopsy and an outpatient waiting all need the scanner. How do you decide the order?
What they are checking: Prioritizing by clinical urgency and communicating delays clearly to the teams and patients who are waiting.
You notice something on the images that looks urgent, like a bleed. What do you do?
What they are checking: Knowing to alert the radiologist right away rather than letting a critical finding wait in the normal reading queue.
About the work
The posting lists biopsies, TAVR, coronary CT, Watchman, OR planning scans, ablations and fiducial placement. Which of those have you done, and walk me through one.
What they are checking: Whether they have real experience with at least three of the advanced procedures this role specifically requires.
How do you screen a patient before giving IV contrast?
What they are checking: Checking kidney function, allergy history and medications like metformin to prevent a contrast reaction or kidney injury.
Talk me through what you do if a patient starts reacting to contrast on the table.
What they are checking: Recognizing mild versus severe reactions quickly and knowing the steps to take and who to call.
How do you keep radiation dose as low as reasonably possible, especially for a child or a young adult?
What they are checking: Applying ALARA through protocol choice, technique and positioning rather than just running the default scan.
For a coronary CT, what do you do to get a good heart rate and a clean scan?
What they are checking: Understanding heart rate control, gating and breath holds, which decide whether a cardiac study is usable.
