Mammographer Interview Questions & Guide
Positioning critique, compression conversations and screening-programme QC — what mammography interviews really test.
- Typical format
- Panel + image critique
- Length
- 30–45 min
- Core themes
- Positioning quality, QC, empathy
- Classic test
- Critique CC/MLO positioning
Clinical & Technical
What makes a technically good MLO view? Critique one for us.
What they’re testing: Positioning standards are the core craft — expect a live critique.
A strong answer covers
- Pectoral muscle to nipple level at the correct angle, relaxed and convex
- Inframammary fold open, nipple in profile, no skin folds, breast lifted ‘up and out’
- Symmetry with the paired view; adequate compression without blur
- Use the PGMI (or local) grading language and say what you’d correct
Why do we compress, and how do you explain it to a patient who’s dreading it?
What they’re testing: Physics + empathy in one answer — exactly the mammographer’s job.
A strong answer covers
- Thinner tissue: less scatter, less dose, less motion, better separation of structures
- Explain in patient language: ‘firm pressure for a few seconds that makes the picture clearer and the dose lower’
- Patient controls the pace; communicate throughout; stop means stop
- Mention techniques for tolerance: timing with the breath, gradual application
A patient has implants. How does your technique change?
What they’re testing: Implant-displacement competence is a standard checkpoint.
A strong answer covers
- Eklund (implant-displaced) views in addition to standard views where the implant allows
- Manual exposure considerations; AEC unreliable over implant
- Gentler compression on implant-inclusive views; rupture concerns → don’t force
- Know when MRI is the answer for implant integrity
Safety
What daily/weekly QC does a mammography unit need?
What they’re testing: Screening-programme discipline; mammography is the most QC-audited modality.
A strong answer covers
- Daily/weekly phantom image checks and detector checks per programme schedule
- AEC consistency, compression force calibration checks at their intervals
- Documentation and action thresholds — who you tell when a test fails, and the unit comes out of use
- Name your framework: NHSBSP/ACR MQSA or local equivalent
How do you think about dose in mammography?
What they’re testing: Dose literacy specific to a screening population of well women.
A strong answer covers
- Screening irradiates healthy people — optimisation duty is at its highest
- Mean glandular dose as the metric; kept under programme limits and audited
- Compression, correct target/filter selection and positioning right-first-time as dose tools
- Repeat rate awareness — every retake doubles that view’s dose
Patient Care
The screening recall letter has terrified your patient. She asks ‘do I have cancer?’. What do you say?
What they’re testing: Recall anxiety management — daily reality in assessment clinics.
A strong answer covers
- Honest context: most recalls are not cancer — extra views/ultrasound usually resolve them
- Don’t promise outcomes; explain today’s steps and when she’ll know more
- Calm, unrushed manner; privacy; written information
- Know the clinic pathway so your explanation matches what actually happens
How do you make mammography accessible for a patient with limited mobility or a disability?
What they’re testing: Inclusion and problem-solving under positioning constraints.
A strong answer covers
- Pre-plan: extra time slots, hoists/wheelchair-adapted technique, second radiographer
- Modified positioning while protecting image quality; document limitations
- Dignity and consent throughout; involve carers as the patient wishes
- Honesty about diagnostic limits and alternative pathways where views are impossible
Behavioural
Tell me about a time you made, or nearly made, an error at work. What did you do?
What they’re testing: Honesty, insight and safety culture — not whether you’re error-free.
A strong answer covers
- Pick a real, low-drama example and own it plainly
- Walk through disclosure: who you told, how fast, what the incident report said
- Finish with the system change or personal habit that came out of it
- Never claim you’ve never made a mistake — that reads as unsafe
Describe a conflict with a colleague and how you resolved it.
What they’re testing: Teamworking under pressure; whether you escalate appropriately rather than personally.
A strong answer covers
- Use STAR: the situation, your specific actions, the outcome
- Show you addressed the issue directly and early, not via gossip
- Acknowledge the other person’s perspective credibly
- End with the working relationship intact or improved
The list is overrunning, an inpatient add-on arrives, and an outpatient is complaining about the wait. What do you do?
What they’re testing: Prioritisation, communication and knowing when to call for help.
A strong answer covers
- Triage on clinical urgency first, not on who is loudest
- Communicate revised expectations to everyone waiting
- Escalate to the coordinator/senior early rather than silently absorbing it
- Mention protecting scan quality — rushing is where errors happen
Why mammography, and why this department?
What they’re testing: Genuine motivation and whether you’ve done your homework on them.
A strong answer covers
- Tie your interest to concrete experience (placement, cases, a mentor)
- Name something specific about their service — equipment, specialties, research, reputation
- Connect their needs to what you bring
- Avoid generic answers that would fit any hospital
Questions to Ask Them
Interviews end with “any questions for us?” — and a flat “no” wastes free marks. Pick two or three:
What does the first six months look like for someone joining this team?
Why it lands: Shows you think about onboarding and fit, and surfaces how structured their support actually is.
How is out-of-hours / on-call structured, and how is it staffed?
Why it lands: Practical, and interviewers respect candidates who ask; vague answers are a flag.
What CPD or postgraduate study does the department support?
Why it lands: Signals ambition; most mammography interviews score commitment to development.
What’s the equipment fleet and is any replacement planned?
Why it lands: Shows technical curiosity and tells you what you’d actually be working on.
How does the team handle incident reporting and learning from errors?
Why it lands: A safety-culture question — asking it marks you as a mature clinical professional.
