What is the Infectious Diseases ST4 interview, and how do you practise for it?
Combined Infection Training ST4 (Group 1) national interview, about 45 minutes: three 10-minute stations, each with its own pair of interviewers, and five scored questions in all. Station 1 is a prepared 3-minute research-paper presentation with discussion, then suitability and commitment; Station 2 is a brief written clinical scenario from any infection specialty, then an ethics, professionalism and governance situation given verbally; Station 3 is medical registrar suitability, opened by a one-minute summary of your acute take experience. Here, one examiner asks the questions. MedMock lets you practise it out loud against an AI interview panel, with examiner-style feedback on any station you finish.

About Infectious Diseases (ST4) recruitment
- The lead recruiter for combined infection training is Scotland.
- Group 1 includes infectious diseases programmes that are dual accredited with general internal medicine, and it is not possible to single accredit in infectious diseases.
- Group 1 eligibility requires completion of the internal medicine training stage 1 programme or equivalent.
- Group 1 candidates answer an additional medical registrar suitability question lasting ten minutes, focused on two Capabilities in Practice from the Internal Medicine Stage 1 curriculum.
- With the medical registrar question included, the raw interview score is the sum of ten scores and must be 30 or above. An applicant found not appointable for ST3 cannot be considered appointable for ST4.
- Applicants in contention for both vacancies get two independent final assessment scores and rankings, ranked against the other applicants within each vacancy.
- All infection trainees spend two years on combined infection training, then three further years of higher specialty training in ID/general medicine, ID/microbiology or ID/virology.
