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
Describe a time you had to mentor or train another technologist on a CT technique or workflow. What was the situation and how did you approach it?
actual mentoring experience, since the posting explicitly requires mentoring newer techs
Tell me about a quality control check you caught that would have affected image quality or patient safety if it had gone unnoticed.
whether QC and daily log review are treated as a real responsibility or an afterthought
Tell me about a time a radiologist or ordering physician questioned your protocol choice or positioning. How did you respond?
ability to advocate for sound technical judgment while staying collaborative with radiologists
Technical
Walk me through how you set your technical factors for a routine chest and abdomen CT on an average-sized adult, and what makes you adjust those factors on the fly.
whether the candidate genuinely understands independent selection and modification of technique rather than relying on presets
Tell me about your experience with contrast injection. How do you screen a patient before you push contrast, and what do you do if you notice signs of extravasation or a reaction mid-injection?
safety judgment and protocol knowledge around IV contrast, since injection is done under radiologist supervision but the tech is first line
How comfortable are you with 3-D reconstruction and CT angiography on an AW workstation, and can you give an example of a case where the post-processing changed how the exam was read?
hands-on proficiency with the specific workstation and advanced study types named in the posting, not just basic scanning
Walk me through how you handle charge capture and HIS/RIS documentation at the end of a shift. What happens if you notice a discrepancy in the daily log?
reliability with the administrative side of the job, since the posting calls out charge entry and log review specifically
Describe a case where cross-sectional anatomy knowledge helped you catch something unusual on a scan before the radiologist reviewed it.
depth of anatomical knowledge beyond rote scanning protocols
Situational
You're covering call and a trauma patient comes in needing an immediate CT, but your prior patient's images haven't been verified in PACS yet. How do you handle both at once?
prioritization under a fast-paced, understaffed call scenario and understanding of the PACS verification workflow
How do you approach positioning and communication differently between a scared pediatric patient, a confused elderly patient, and an anxious adult who's claustrophobic?
actual age-specific competency required by the posting, not textbook language
This role has rotating weekends every fourth week, call every eighth week, and a midday 12 to 8:30 shift. What has your experience been with a schedule like this, and how do you manage your energy and focus for an evening shift after a night on call?
realistic fit with the specific, demanding schedule rather than generic willingness to work shifts
You notice a coworker skipping a radiation safety step to save time during a busy stretch. What do you do?
commitment to radiation protection standards even under peer or time pressure
You're not yet CT registered but have your six months of CT experience going into this role. What's your plan for getting ARRT CT certified within six months of hire, and how do you study on top of a full clinical schedule?
concrete follow-through on the mandatory certification timeline, a hard requirement of the posting
