What interviewers for Medical Officer actually ask
The question bank for this role is still being written. These are the first three competencies in the model the interview is scored against.
Builds a differential from history and examination, orders investigations that change management, and revises the working diagnosis when findings do not fit.
Identifies the sick patient early, initiates resuscitation and treatment within competence, and calls for senior or specialist help without delay.
Explains diagnosis, risks and options in plain language, obtains informed consent, breaks bad news with care, and respects a patient's right to decline.
What they are really assessing
Interviewers rarely score whether you seemed nice. They score against a model like this one, usually without telling you it exists. Each competency has a weak, adequate and strong shape, and the difference is almost always the level of specific detail you volunteer without being asked.
Diagnostic reasoning
Builds a differential from history and examination, orders investigations that change management, and revises the working diagnosis when findings do not fit.
- Weak
- Describes diagnosis as pattern-matching or 'ordering the usual bloods'; cannot name the differentials considered or an occasion when the first diagnosis was wrong.
- Adequate
- Presents a case with a sensible differential and investigations, but cannot articulate the pre-test reasoning or what would have made them change course.
- Strong
- Presents a specific case: the differential ranked by likelihood and danger, why each test was ordered, the finding that did not fit, how they revised the diagnosis, and what they learned about their own bias.
Recognising deterioration & escalation
Identifies the sick patient early, initiates resuscitation and treatment within competence, and calls for senior or specialist help without delay.
- Weak
- Cannot describe a specific deteriorating patient; speaks about 'stabilising' without naming actions; suggests calling for help is a sign of weakness or was delayed.
- Adequate
- Describes a case with sensible initial management and a call to a senior, but timing and the content of the escalation call are vague.
- Strong
- Describes the patient, the trigger (observations, lactate, mental state), the ABCDE actions taken, what they said to the senior and when, the outcome and the debrief or M&M discussion.
Communication & shared decision-making
Explains diagnosis, risks and options in plain language, obtains informed consent, breaks bad news with care, and respects a patient's right to decline.
- Weak
- Describes consent as getting a signature; examples of breaking bad news are generic; a patient refusing treatment is framed as 'non-compliant'.
- Adequate
- Uses a structure for difficult conversations and gives an example, but cannot say how they checked understanding or handled a patient whose choice they disagreed with.
- Strong
- Describes a specific conversation: how they prepared, the words used, checking understanding, the patient's decision (including one they disagreed with), how it was documented and what happened next.
Clinical governance & error disclosure
Participates in audit, morbidity and mortality review and incident reporting; discloses errors to patients honestly and changes practice as a result.
- Weak
- Cannot describe an error of their own; treats M&M as blame; no audit they have run or contributed to.
- Adequate
- Describes an adverse event and an incident report, and an audit they took part in, but the disclosure to the patient and the resulting practice change are unclear.
- Strong
- Describes their own error or a near-miss: what happened, how they told the patient and family, the incident and M&M process, the system change proposed, and evidence that it was implemented.
Leading the clinical team
Runs ward rounds, resuscitations or theatre lists with clear roles, supervises juniors safely, and handles conflict with nursing and other specialties constructively.
- Weak
- Describes leadership as giving instructions; cannot give an example of a junior's mistake they caught or a disagreement with nursing staff resolved well.
- Adequate
- Describes supervising juniors and running a round, and a disagreement with nursing, but the example lacks what they did differently afterwards.
- Strong
- Gives a specific situation (a resuscitation, an overloaded call, a junior out of depth): how roles were assigned, what they said in the moment, how the conflict or error was handled and the debrief afterwards.
Managing uncertainty & resources
Makes safe decisions with incomplete information and limited beds, theatre time or investigations, and can justify the trade-offs made.
- Weak
- Says resource constraints 'are not my problem' or that they 'order everything to be safe'; cannot describe a prioritisation decision between patients.
- Adequate
- Describes prioritising a theatre list or ICU bed and choosing investigations carefully, but the reasoning about risk to the patients not prioritised is missing.
- Strong
- Describes a specific decision (ICU bed, referral out, withholding an investigation), the risks to each patient, who they consulted, how it was communicated to families and the outcome.
Ethics, confidentiality & professionalism
Applies HPCSA ethical rules on confidentiality, conflicts of interest, capacity and end-of-life decisions, and raises concerns about colleagues' fitness to practise.
- Weak
- Cannot describe an ethical dilemma they faced; treats confidentiality as absolute or ignores it; would not raise a concern about an impaired colleague.
- Adequate
- Describes a dilemma (capacity, minor's consent, disclosure) and a reasonable decision, but did not seek advice or document the reasoning.
- Strong
- Describes a specific dilemma, the principles and rules that applied, who they consulted (senior, ethics committee, medical protection), what they decided, how it was documented and the follow-up.

The same shape as a real first-round interview, pitched at mid-level Medical Officer and scored throughout.
Warm-up, then Motivation & fit
Build rapport, settle nerves, and get a short walk-through of your background. Why this role, why this employer, and what you are actually looking for.
Your experience
Two or three real situations from your CV in depth: context, what you did, what happened, what you would change.
Pitched at mid-level scope: registrar or experienced medical officer: runs the ward or clinic day-to-day, first call for complex cases, teaches juniors and participates in audit and research.
Role-specific questions
The core competencies and domain knowledge for the role, with follow-ups on anything vague.
Drawn from this role's domain: differential diagnosis for common presentations in the candidate's specialty, aBCDE approach and early management of the deteriorating patient and informed consent, capacity and consent for minors, and the rest of the competency model.
Your questions, then Wrap-up
Your questions for the interviewer, and yes, they are assessed. Next steps and a clean finish.
What changes with seniority
The questions barely change between levels. What changes is the answer they will accept.
| Junior | Mid | Senior | |
|---|---|---|---|
| Scope of ownership | Medical officer or junior dentist: manages own patients and lists with consultant cover, supervises interns and students. | Registrar or experienced medical officer: runs the ward or clinic day-to-day, first call for complex cases, teaches juniors and participates in audit and research. | Specialist or consultant: ultimate clinical responsibility for own patients, supervises registrars, contributes to protocols and department governance. |
| Tolerance for ambiguity | Manages routine and moderately complex cases independently; escalates atypical or high-risk cases. | Makes management decisions on complex patients with consultant discussion; handles resource conflicts between patients. | Owns decisions where evidence is thin or patients are at the edge of guidelines; accountable for outcomes. |
| People leadership | Supervises interns and students; first escalation point for nursing at night. | Leads the junior team on rounds and calls; gives formal feedback. | Trains and assesses registrars; handles performance concerns in the team. |
| Who they deal with | Consultants, referring clinics, nursing, pharmacy, families. | Consultants, other specialties, ICU, theatre management, families. | Head of department, hospital management, referrers, medical aids, HPCSA, universities. |
What your report would say
Every competency above scored from your own answers, the sentence that cost you quoted back, and your weakest answers rewritten the way a strong Medical Officer would have said them.
- Describes a specific conversation: how they prepared, the words used, checking understanding, the patient's decision (including one they disagreed with), how it was documented and what happened next.
The format, not a result. Scores on your report come from what you actually said.
